Description

Technical Field

[0001] This invention relates to the field of magnetron technology, and more particularly to an mounting structure for an anode assembly. Background Technology

[0002] A magnetron is a vacuum tube that generates microwaves and is also a core component of a household microwave oven. With the increasing popularity of household microwave ovens, the demand for magnetrons is growing, and the quality requirements for magnetrons are becoming increasingly stringent. The anode assembly, as the primary site of electron movement, is affected by processes such as installation, positioning, and welding, all of which have a significant impact on the magnetron parameters.

[0003] Patent No. ZL 201621408954.7 discloses a magnetron anode assembly and a magnetron equipped with the magnetron anode assembly, including an anode cylinder and a plurality of radially distributed anode blades disposed within the anode cylinder. The upper ends of the plurality of anode blades are provided with a first large connecting ring and a first small connecting ring, and the lower ends of the plurality of anode blades are provided with a second large connecting ring and a second small connecting ring. The upper end of each anode blade is provided with a first mounting groove for mounting the first large connecting ring and the first small connecting ring, and the lower end is provided with a second mounting groove for mounting the second large connecting ring and the second small connecting ring. The first mounting groove is provided with a first protrusion, and the second mounting groove is provided with a second protrusion. The upper ends of a portion of the anode blades are connected to the first large connecting ring through the first protrusion, and the lower ends are connected to the second small connecting ring through the second protrusion. The upper ends of another portion of the anode blades are connected to the first small connecting ring through the first protrusion, and the lower ends are connected to the second large connecting ring through the second protrusion.

[0004] Most current magnetrons use the above structure, with the cross-link embedded in the mounting groove of the anode blade and fixed by welding. This structure is simple, easy to operate, and improves assembly efficiency. However, this structure lacks necessary limiting and positioning mechanisms, leading to inaccurate positioning and loosening during assembly, which can cause positional deviations and cause the magnetron's operating frequency to deviate from the design value. Furthermore, the solder is located between the cross-link and the anode blade, and the contact surface is planar. During welding, the solder spreads irregularly in all directions, resulting in uneven solder distribution, poor welding stability, and problems such as detachment, loosening, and weak welds.

Detailed Implementation

[0041] 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.

[0042] Reference Figures 1 to 7 One embodiment provided by the present invention:

[0043] An anode assembly mounting structure is disclosed. The anode assembly includes an anode cylinder 1, and anode blades 2, a first connecting ring 3, and a second connecting ring 4 installed inside the anode cylinder 1. The anode blades 2 are evenly distributed around the axis of the anode cylinder 1 and arranged radially. One end of the anode blade 2 is welded and fixed to the inner wall of the anode cylinder 1, and the other end is suspended towards the axis of the anode cylinder 1. The anode blades 2 are provided with a first step 500 and a second step 600 on the side near the axis of the anode cylinder 1. The first connecting ring 3 is connected to the anode blade 2 through the first step 500, and the second connecting ring 4 is connected to the anode blade 2 through the second step 600. Adjacent anode blades 2 are connected to each other through the first connecting ring 3 and the second step 600. The anode assembly is characterized in that a solder guiding mechanism 700, a limiting mechanism 800, and a positioning mechanism 900 are respectively provided between the first connecting ring 3 and the first step 500, and between the second connecting ring 4 and the second step 600.

[0044] The anode assembly includes an anode cylinder 1, anode blades 2, a first connecting ring 3, and a second connecting ring 4. The anode cylinder 1 is a cylindrical shape open at both ends. The anode blades 2, the first connecting ring 3, and the second connecting ring 4 are installed inside the anode cylinder 1. There can be eight anode blades 2, two first connecting rings 3, and two second connecting rings 4. The anode blades 2 are placed vertically and evenly distributed around the axis of the anode cylinder 1 in a radial arrangement. One end of the anode blade 2 is welded to the inner wall of the anode cylinder 1. Solder can be placed on the anode blade 2, and after the solder melts, it flows into the gap between the anode blade 2 and the anode cylinder 1 under the action of gravity and capillary action. The solder cools and the weld is fixed. The other end of the anode blade 2 is suspended, and the suspended ends of all the anode blades 2 converge towards the axis of the anode cylinder 1.

[0045] The anode blade 2 has a first step 500 and a second step 600, located on the side closest to the axis of the anode cylinder 1. The first step 500 is used to install the first connecting ring 3, and the second step 600 is used to install the second connecting ring 4. The first connecting ring 3 is connected to the anode blade 2 via the first step 500, and the second connecting ring 4 is connected to the anode blade 2 via the second step 600. Adjacent anode blades 2 are connected to each other via the first connecting ring 3 and the second step 600 and fixed by welding. Solder layers can be provided on the inner wall of the first connecting ring 3 and the outer wall of the second connecting ring 4, respectively. The contact areas between the inner wall of the first connecting ring 3 and the first step 500, and the contact areas between the outer wall of the second connecting ring 4 and the second step 600, serve as the welding areas. After the solder melts, it is distributed within the welding areas, and after the solder cools, the welding is completed.

[0046] The anode assembly also includes a flow guiding mechanism 700, a limiting mechanism 800, and a positioning mechanism 900, located between the first connecting ring 3 and the first step 500, and between the second connecting ring 4 and the second step 600, respectively. The flow guiding mechanism 700 guides the solder, causing the molten solder to converge in the welding area and preventing it from spreading irregularly. This can be achieved through a first solder groove 710, a first protrusion 711, a second solder groove 720, and a second protrusion 721. The limiting mechanism 800 provides a limiting function, securing the first connecting ring 3 to the first step 500 and the second connecting ring 4 to the second step 600. This can be achieved through a first fixing part 810, a first limiting pit 811, a first limiting part 812, a first inclined surface 813, a first tenon joint 814, a second fixing part 820, a second limiting pit 821, a second limiting part 822, a second inclined surface 823, and a second tenon joint 824. The positioning mechanism 900 is used to provide positioning function so that the installation positioning of the first interlocking ring 3 and the second interlocking ring 4 is more accurate. It can be achieved by the first positioning groove 910, the first positioning part 911, the first groove 912, the second positioning groove 920, the second positioning part 921, and the second groove 922.

[0047] This invention, by adding a flow guiding mechanism 700, can guide the flow of solder, causing the molten solder to converge in the welding area, improving solder uniformity and welding stability, and preventing the solder from spreading irregularly in all directions, which could lead to problems such as desoldering, loosening, and weak welding. By adding a limiting mechanism 800 and a positioning mechanism 900, it can provide limiting and positioning functions, ensuring that the first interlocking ring 3 is fastened to the first step 500 and the second interlocking ring 4 is fastened to the second step 600, while improving the accuracy of installation and positioning between the two, overcoming issues such as inaccurate positioning and easy loosening, and preventing the magnetron's operating frequency from deviating from the design value.

[0048] Reference Figure 2 In this embodiment, preferably, the inner wall of the first connecting ring 3 is provided with a solder layer, and the first step 500 includes a first mounting surface 510 and a first supporting surface 511. The first mounting surface 510 is in close contact with the inner wall of the first connecting ring 3, and the first supporting surface 511 is in cooperation with the bottom surface of the first connecting ring 3. The outer wall of the second connecting ring 4 is provided with a solder layer, and the second step 600 includes a second mounting surface 610 and a second supporting surface 611. The second mounting surface 610 is in close contact with the outer wall of the second connecting ring 4, and the second supporting surface 611 is in cooperation with the bottom surface of the second connecting ring 4.

[0049] By providing a solder layer on the inner wall of the first connecting ring 3, the first step 500 includes a first mounting surface 510 and a first supporting surface 511. The first mounting surface 510 is in close contact with the inner wall of the first connecting ring 3, and the first supporting surface 511 mates with the bottom surface of the first connecting ring 3, thus achieving the installation of the first step 500 and the first connecting ring 3. By providing a solder layer on the outer wall of the second connecting ring 4, the second step 600 includes a second mounting surface 610 and a second supporting surface 611. The second mounting surface 610 is in close contact with the outer wall of the second connecting ring 4, and the second supporting surface 611 mates with the bottom surface of the second connecting ring 4, thus achieving the installation of the second step 600 and the second connecting ring 4.

[0050] By setting the above structure, the solder layer melts during the welding process. The melted solder can fill the gap between the first assembly surface 510 and the inner wall of the first interlocking ring 3, and between the second assembly surface 610 and the outer wall of the second interlocking ring 4. The solder is then cooled to achieve welding and fixation.

[0051] Reference Figure 3In this embodiment, preferably, the flow guiding mechanism 700 includes a first solder groove 710 and a second solder groove 720; the first solder groove 710 is disposed on the first mounting surface 510 and is arranged in a ring around the axis of the anode cylinder 1, and the inner side wall of the first connecting ring 3 is provided with a first protrusion 711 that matches the first solder groove 710, and the first protrusion 711 is embedded in the first solder groove 710; the second solder groove 720 is disposed on the second mounting surface 610 and is arranged in a ring around the axis of the anode cylinder 1, and the outer side wall of the second connecting ring 4 is provided with a second protrusion 721 that matches the second solder groove 720, and the second protrusion 721 is embedded in the second solder groove 720.

[0052] A first solder groove 710 is provided on the first assembly surface 510. The first solder groove 710 is arranged in a ring and distributed around the axis of the anode cylinder 1.

After the solder melts, it will converge in the gap between the first protrusion 711 and the first solder groove 710, and between the second protrusion 721 and the second solder groove 720, guiding the flow direction of the solder, avoiding the solder from spreading irregularly in all directions, and improving the welding stability and solder concentration.

[0054] In this embodiment, preferably, the first solder groove 710 and the first protrusion 711 are arranged in several groups at intervals, and the longitudinal section of the first mounting surface 510 and the inner sidewall of the first interlocking ring 3 is wavy; the second solder groove 720 and the second protrusion 721 are arranged in several groups at intervals, and the longitudinal section of the second mounting surface 610 and the outer sidewall of the second interlocking ring 4 is wavy.

[0055] By setting several groups of first solder grooves 710 and first protrusions 711 at intervals, the first solder groove 710 can be an arc groove or a U-shaped groove, so that the longitudinal section of the first mounting surface 510 and the inner sidewall of the first interlocking ring 3 is wavy. By setting several groups of second solder grooves 720 and second protrusions 721 at intervals, the second solder groove 720 can be an arc groove or a U-shaped groove, so that the longitudinal section of the second mounting surface 610 and the outer sidewall of the second interlocking ring 4 is wavy.

[0056] By setting the above structure, the shape of the contact surface can be optimized, and multiple layers of solder flow channels can be formed between the first assembly surface 510 and the inner side wall of the first interlocking ring 3, and between the second assembly surface 610 and the outer side wall of the second interlocking ring 4. The flow channels of each layer are interconnected and completely cover the welding area. After the solder melts, it can be concentrated in the welding area to prevent solder leakage and further improve the welding stability and solder concentration.

[0057] Reference Figure 4 In this embodiment, preferably, the limiting mechanism 800 includes a first fixing part 810 and a second fixing part 820; the first fixing part 810 is disposed on the first support surface 511 and is disposed on the side away from the axis of the anode cylinder 1, and the first interlocking ring 3 is fastened between the first fixing part 810 and the first assembly surface 510; the second fixing part 820 is disposed on the second support surface 611 and is disposed on the side close to the axis of the anode cylinder 1, and the second interlocking ring 4 is fastened between the second fixing part 820 and the second assembly surface 610.

[0058] By providing a first fixing part 810 on the first support surface 511, the first fixing part 810 is located on the side away from the axis of the anode cylinder 1. A first interlocking ring 3 is formed between the first fixing part 810 and the first mounting surface 510, and the distance between the two is equal to the width of the first interlocking ring 3. The first interlocking ring 3 is fastened between the first fixing part 810 and the first mounting surface 510. By providing a second fixing part 820 on the second support surface 611, the second fixing part 820 is located on the side closer to the axis of the anode cylinder 1. A second interlocking ring 4 is formed between the second fixing part 820 and the second mounting surface 610, and the distance between the two is equal to the width of the second interlocking ring 4. The second interlocking ring 4 is fastened between the second fixing part 820 and the second mounting surface 610.

[0059] By setting the above structure, installation constraints can be formed on both the inner and outer sides of the first interlocking ring 3 and the inner and outer sides of the second interlocking ring 4, thereby improving installation stability and positioning accuracy.

[0060] In this embodiment, preferably, the first fixing part 810 has a first limiting pit 811 on the contact surface with the first connecting ring 3, and the first connecting ring 3 has a first limiting part 812 that matches the first limiting pit 811, with the first limiting part 812 embedded in the first limiting pit 811; the second fixing part 820 has a second limiting pit 821 on the contact surface with the second connecting ring 4, and the second connecting ring 4 has a second limiting part 822 that matches the second limiting pit 821, with the second limiting part 822 embedded in the second limiting pit 821.

By providing a second limiting pit 821 in the second fixing part 820 and a second limiting part 822 in the second connecting ring 4, the second limiting pit 821 and the second limiting pit 821 are matched in shape and position and are located at the contact surface between the second fixing part 820 and the second connecting ring 4, and the second limiting part 822 is embedded in the second limiting pit 821.

[0062] By setting the above structure, when installing the first interlocking ring 3 and the second interlocking ring 4, precise positioning can be provided by the assembly relationship between the first limiting part 812 and the first limiting pit 811, and between the second limiting part 822 and the second limiting pit 821. In addition, considering the ease of installation, most of the assembly adopts clearance fit, and there is a certain amount of looseness between the components. This structure can form a constraint in the axial direction of the anode tube, which can prevent the first interlocking ring 3 and the second interlocking ring 4 from falling off.

[0063] Reference Figure 5 In this embodiment, preferably, the limiting mechanism 800 includes a first inclined surface 813 and a second inclined surface 823; the first inclined surface 813 is disposed on the first assembly surface 510 and the angle between it and the first support surface 511 is an acute angle; the inner side wall of the first connecting ring 3 is provided with a first tenon joint 814 that matches the first inclined surface 813, and the first tenon joint 814 is tenon-jointed with the first inclined surface 813; the second inclined surface 823 is disposed on the second assembly surface 610 and the angle between it and the second support surface 611 is an acute angle; the outer side wall of the second connecting ring 4 is provided with a second tenon joint 824 that matches the second inclined surface 823, and the second tenon joint 824 is tenon-jointed with the second inclined surface 823.

The second inclined surface 823 is inclined away from the axis of the anode cylinder 1, so that the angle between the second inclined surface 823 and the second support surface 611 is an acute angle. A second tenon 824 is provided on the outer wall of the second connecting ring 4. The second tenon 824 matches the shape and position of the second inclined surface 823, and the second tenon 824 is tenoned and installed with the second inclined surface 823. The inclination angles of the first inclined surface 813 and the second inclined surface 823 are small, which is intended to play a limiting role after tenoning, so as not to affect the longitudinal installation of the first connecting ring 3 and the second connecting ring 4.

[0065] By setting up the above structure, when installing the first interlocking ring 3 and the second interlocking ring 4, longitudinal pressure is applied to the first interlocking ring 3 and the second interlocking ring 4, so that they are squeezed into the installation area of ​​the first step 500 and the second step 600. The tenon and mortise relationship limits their movement and provides longitudinal constraint, preventing the first interlocking ring 3 and the second interlocking ring 4 from leaving the installation area and improving installation stability.

[0068] By setting the above structure, accurate positioning can be provided when installing the first interlocking ring 3 and the second interlocking ring 4 through the snap-fit ​​relationship between the first positioning part 911 and the first positioning groove 910, and the second positioning part 921 and the second positioning groove 920. At the same time, restricting the axial rotation of the first interlocking ring 3 and the second interlocking ring 4 around the anode cylinder 1 can provide circumferential constraint and improve assembly stability.

[0069] In this embodiment, preferably, the first positioning groove 910 is opened along the axial direction of the anode cylinder 1 and extends to the first support surface 511, and the width of the bottom wall of the first positioning groove 910 is greater than the width of the opening of the first positioning groove 910; the second positioning groove 920 is opened along the axial direction of the anode cylinder 1 and extends to the second support surface 611, and the width of the bottom wall of the second positioning groove 920 is greater than the width of the opening of the second positioning groove 920.

[0070] By setting a first positioning groove 910 to be opened along the axial direction of the anode cylinder 1, the first positioning groove 910 is a blind groove. The beginning of the first positioning groove 910 provides an insertion space for the first positioning part 911, and the end of the first positioning groove 910 extends to the first support surface 511, so that the first connecting ring 3 maintains the same installation depth on each anode blade 2. The width of the bottom wall of the first positioning groove 910 is greater than the width of the opening of the first positioning groove 910. The direction of the opening of the first positioning groove 910 is opposite to the direction of the axis of the anode cylinder 1. The bottom wall of the first positioning groove 910 and the opening of the first positioning groove 910 are set opposite to each other. It can be understood that the space inside the first positioning groove 910 narrows towards the opening direction of the first positioning groove 910. The cross-section of the first positioning groove 910 can be T-shaped or trapezoidal. By setting a second positioning groove 920 along the axial direction of the anode cylinder 1, the second positioning groove 920 is a blind groove. The beginning of the second positioning groove provides an insertion space for the second positioning part 921. The end of the second positioning groove 920 extends to the second support surface 611, so that the second interlocking ring 4 maintains the same installation depth on each anode blade 2. The width of the bottom wall of the second positioning groove 920 is greater than the width of the opening of the second positioning groove 920. The direction of the opening of the second positioning groove 920 is the same as the direction of the axis of the anode cylinder 1. The bottom wall of the second positioning groove 920 and the opening of the second positioning groove 920 are set opposite to each other. It can be understood that the space inside the second positioning groove 920 narrows towards the opening direction of the second positioning groove 920. The cross-section of the second positioning groove 920 can be T-shaped or trapezoidal.

[0071] By setting the above structure, after the first positioning part 911 is engaged with the first positioning groove 910 and the second positioning part 921 is engaged with the second positioning groove 920, since the groove space of the first positioning groove 910 and the second positioning groove 920 is narrowed, the first positioning part 911 and the second positioning part 921 can be tightly held to prevent them from leaving the groove space, thereby playing a limiting role, providing radial constraint, and improving assembly stability.

[0072] Reference Figure 7 In this embodiment, preferably, the positioning mechanism 900 includes a first groove 912 and a second groove 922; the first groove 912 is disposed on the first connecting ring 3, the width of the first groove 912 is equal to the width of the first support surface 511, and the first groove 912 is engaged with the first support surface 511; the second groove 922 is disposed on the second connecting ring 4, the width of the second groove 922 is equal to the width of the second support surface 611, and the second groove 922 is engaged with the second support surface 611.

[0073] A first groove 912 is provided in the first connecting ring 3. The shape of the groove 912 matches the cross-sectional shape of the first support surface 511, and the width of the first groove 912 is equal to the width of the first support surface 511. The first groove 912 engages with the first support surface 511. A second groove 922 is provided in the second connecting ring 4. The shape of the groove 922 matches the cross-sectional shape of the second support surface 611, and the width of the second groove 922 is equal to the width of the second support surface 611. The second groove 922 engages with the second support surface 611.

[0074] By setting the above structure, when the first interlocking ring 3 and the second interlocking ring 4 are installed axially along the anode tube on the first support surface 511 and the second support surface 611, the first groove 912 and the first support surface 511, and the second groove 922 and the second support surface 611, are mutually engaged, which can improve the positioning accuracy. In addition, since the anode blades 2 are arranged radially, the first groove 912 and the second groove 922 can limit the distance between adjacent anode blades 2, further improving the assembly accuracy.

[0075] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
