Description

Technical Field

[0001] This utility model relates to the field of electric stove technology, and in particular to a plasma flame confinement device for electric stoves. Background Technology

[0002] When electric stoves are in operation, especially those using plasma flames, the shape and range of the flame need to be effectively constrained to ensure thermal efficiency and heating uniformity. Existing technologies use a constraining shell to constrain the flame.

[0003] The existing constraint shell is fixed to the support frame by connectors. However, the existing fixing structure has insufficient connection strength. In the high-temperature operation or vibration environment of the electric stove, the constraint shell may loosen or shift. The constraint shell may also deform due to uneven stress, which will affect the flame constraint effect and the operation stability of the equipment. During operation, the electric stove needs to monitor the working temperature through a temperature sensor. The temperature sensor needs to be maintained or replaced. The temperature sensor installation structure in the existing technology is complicated and is mostly installed by bolt fastening or welding. This makes the disassembly process cumbersome, and the maintenance work time-consuming and labor-intensive, which reduces the maintenance efficiency of the equipment and affects the normal use of the equipment.

[0004] Therefore, this utility model proposes a plasma flame confinement device for electric stoves to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems in the existing technology of plasma flame confinement devices for electric stoves, such as the insufficiently stable fixing method of the confinement shell, which may loosen, shift or deform in high temperature or vibration environments, and the complex installation structure of the temperature sensor, which leads to cumbersome and laborious disassembly and maintenance, affecting maintenance efficiency, this utility model aims to provide an improved plasma flame confinement device for electric stoves that can effectively solve the above problems.

[0006] This utility model provides a plasma flame confinement device for an electric stove, comprising: a support frame, a confinement shell installed on the top of the support frame, a fixing mechanism, and an installation mechanism.

[0007] The fixing mechanism includes a fixing block, bolts, connecting blocks, connecting rods, and clamping blocks; the installation mechanism includes an installation block, a locking block, a knob, a limit block, a temperature sensor, a limit hole, and a slot.

The inner wall of the connecting rod is rotatably connected to the clamping block, and the end of the clamping block is rotatably connected to the inner wall of the connecting block. When the bolt rotates, it drives the connecting block to move so as to pull the clamping block to rotate and lock the outer wall of the constraint shell.

[0009] Furthermore, the mounting block is fixedly connected to the left side of the outer wall of the constraint housing. The lower part of the inner wall of the mounting block is rotatably connected to the locking block. The inner wall of the mounting block is rotatably connected to the knob. The outer wall of the locking block has a locking groove. The limiting block is installed on the outer wall of the mounting block. The top wall of the limiting block is fixedly connected to the temperature sensor. The outer wall of the limiting block has a limiting hole. The end of the locking block is slidably connected to the inner wall of the limiting hole. When the knob is rotated to coincide with the locking groove, the locking block can rotate so that the end of the locking block slides out of the limiting hole.

[0010] Preferably, the top of the support frame has a ring-shaped structure to support the constrained shell.

[0011] Preferably, the inner wall of the clamping block is provided with an arc-shaped groove to increase the contact area with the outer wall of the constraint shell and the clamping stability.

[0012] Preferably, the inner wall of the connecting block and the end of the clamping block are rotatably connected by a pin.

[0013] Preferably, the mounting block and the constraint shell are fixedly connected by welding.

[0014] Preferably, when the locking block slides in connection with the inner wall of the limiting hole, its end has a wedge-shaped structure to enhance the reliability of insertion and locking.

[0015] Preferably, the inner wall of the limiting hole is machined with a guide slope to facilitate the smooth sliding of the end of the locking block into or out.

[0016] Preferably, the knob's pivot passes through the mounting block and aligns with the slot of the locking block.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting a fixing mechanism, uses the rotation of bolts to drive the connecting block to move, and links multiple connecting rods and clamping blocks, so that the clamping blocks can simultaneously tighten inward from multiple directions and lock the constraint shell. This solves the problem that the existing constraint shell fixing method is not stable enough and is prone to displacement or deformation in high temperature or vibration environment. It achieves the effect of multi-point uniform locking, high fixing reliability, and ensuring the stability of the constraint shell structure.

[0019] 2. This utility model, by setting up an installation mechanism, uses a knob and a slot on the card block to control the rotation locking and release of the card block, so that the end of the card block can easily slide out of the limiting hole of the limiting block. This solves the problem of complex disassembly and inconvenient maintenance of components such as temperature sensors in the prior art, which affects the efficiency of equipment use. It achieves the effect of quickly disassembling and installing temperature sensors without complicated tools, greatly improving the convenience of equipment maintenance. Attached Figure Description

[0029] Example:

[0030] Please refer to Figures 1 to 6 This utility model provides a plasma flame confinement device for electric stoves, which aims to solve the problems in the prior art where the confinement shell 201 is not fixed securely enough, is prone to displacement or deformation during long-term use, and the temperature sensor 301 is inconvenient to disassemble and maintain, thus affecting the efficiency of equipment use and maintenance.

[0031] Please refer to Figures 1 to 3The electric stove plasma flame confinement device includes a support frame 1 and a confinement shell 201 installed at the top of the support frame 1. The top of the support frame 1 has a ring structure to support the confinement shell 201. The electric stove plasma flame confinement device also includes a fixing mechanism 2, which is located inside the support frame 1. The fixing mechanism 2 includes a fixing block 204, a bolt 205, a connecting block 206, a connecting rod 203, and a clamping block 202. The fixing block 204 is fixedly connected to the middle of the inner bottom wall of the support frame 1. The bolt 205 is threadedly connected to the inner wall of the fixing block 204. The connecting block 206 is rotatably connected to the upper middle part of the outer wall of the bolt 205. Multiple connecting rods 203 are equidistantly rotatably connected to the outer wall of the fixing block 204. The inner wall of the connecting rod 203 is rotatably connected to the clamping block 202. The inner wall of the connecting block 206 and the end of the clamping block 202 are rotatably connected by a pin. The inner wall of the clamping block 202 is provided with an arc-shaped groove to improve the contact area with the outer wall of the confinement shell 201 and the clamping stability.

[0032] Please refer to Figure 1 , Figures 4 to 6 The plasma flame confinement device for the electric stove also includes an installation mechanism 3. The installation mechanism 3 includes an installation block 307, a locking block 304, a knob 306, a limiting block 303, a temperature sensor 301, a limiting hole 302, and a slot 305. The installation block 307 is fixedly connected to the left side of the outer wall of the confinement housing 201. The installation block 307 and the confinement housing 201 are fixedly connected by welding. The locking block 304 is rotatably connected to the lower middle part of the inner wall of the installation block 307. The knob 306 is rotatably connected to the inner wall of the installation block 307. The rotating shaft of the knob 306 passes through the installation block 307 and is connected to the locking block. The slots 305 of the 304 are aligned. The outer wall of the 304 has a slot 305. The limiting block 303 is installed on the outer wall of the mounting block 307. The temperature sensor 301 is fixedly connected to the top wall of the limiting block 303. The outer wall of the limiting block 303 has a limiting hole 302. The inner wall of the limiting hole 302 is machined with a guide slope so that the end of the 304 can slide in or out smoothly. The end of the 304 is slidably connected to the inner wall of the limiting hole 302. When the 304 is slidably connected to the inner wall of the limiting hole 302, the end has a wedge-shaped structure to enhance the reliability of insertion and locking.

[0033] Please refer to Figure 3 and Figure 4The fixing mechanism 2 has a fixing block 204, which is fixedly connected to the middle of the inner bottom wall of the support frame 1. The fixing block 204 serves as the basic support component of the fixing mechanism 2 and can withstand the reaction force generated by subsequent clamping actions. The inner wall of the fixing block 204 is machined with internal threads, and the outer wall of the bolt 205 is machined with external threads that match the internal threads of the fixing block 204. The bolt 205 is threadedly connected to the inner wall of the fixing block 204 by thread engagement. The connecting block 206 is sleeved on the upper middle part of the outer wall of the bolt 205. The connecting block 206 and the bolt 205 are rotatably connected, so that when the bolt 205 rotates in place, it can drive the connecting block 206 to move up and down along the axis of the bolt 205. Multiple connecting rods 203 are evenly distributed on the circumferential surface of the outer wall of the fixing block 204. One end of each connecting rod 203 is rotatably connected to the outer wall of the fixing block 204 through a rotating shaft, and the other end of the connecting rod 203 extends outward to form a fulcrum structure for installing the clamping block 202.

[0034] The fixing mechanism 2 is provided with multiple clamping blocks 202, each corresponding to a connecting rod 203. The clamping block 202 is located in the inner space of the connecting rod 203, and its middle position is rotatably connected to the inner wall of the connecting rod 203 via a pin. This allows the clamping block 202 to swing around the connection point on the connecting rod 203 in a lever-like manner. The end of the clamping block 202 extends into the inner space of the connecting block 206, and the inner wall of the connecting block 206 is rotatably connected to the end of the clamping block 202 via a pin. This multi-link mechanical transmission structure ensures that when the connecting block 206 moves downward under the drive of the bolt 205, it can simultaneously pull the ends of all the clamping blocks 202 downward. The movement forces the first end of the clamping block 202 to swing inward and tighten around the connecting rod 203. In the assembled state, the constraint shell 201 is placed on the top of the support frame 1, and the first end of the clamping block 202 faces the outer wall of the constraint shell 201. By rotating the bolt 205, the connecting block 206 is driven to move downward, which drives the clamping block 202 to clamp the constraint shell 201. In order to increase the contact area and stability of clamping, the inner wall of the first end of the clamping block 202 is provided with an arc-shaped groove to improve the contact area with the outer wall of the constraint shell 201 and the clamping stability. Through this spiral drive and connecting rod clamping structure, a strong lock is achieved on the constraint shell 201, which effectively prevents loosening or displacement in high temperature or vibration environments.

[0035] Please refer to Figure 1 and Figure 2 The top of the support frame 1 has a ring structure for supporting the constraint housing 201. The constraint housing 201 is a cylindrical or ring-shaped component, and its lower edge is placed on the ring structure at the top of the support frame 1. The support frame 1 provides a stable radial limiting and axial support base for the constraint housing 201, ensuring that the constraint housing 201 can be accurately initially positioned before the installation and fixing mechanism 2 is installed.

[0036] Please refer to Figure 3 and Figure 4 The clamping structure of the fixing mechanism 2 has been further optimized. The inner wall of the first end of the clamping block 202, which is used to contact the outer wall of the constraint housing 201, is provided with an arc-shaped groove to improve the contact area and clamping stability with the outer wall of the constraint housing 201. The radius of curvature of the arc-shaped groove matches the radius of curvature of the outer wall of the constraint housing 201, so that the clamping block 202 can form a surface contact with the outer wall of the constraint housing 201 when clamped, rather than a point contact or line contact, which greatly enhances the friction and fixing reliability of the clamping. At the same time, at the transmission connection between the connecting block 206 and the clamping block 202, the inner wall of the connecting block 206 and the end of the clamping block 202 are rotatably connected by a pin. The pin passes through the connecting hole at the corresponding position of the connecting block 206 and the connecting hole at the end of the clamping block 202, realizing flexible rotational cooperation. This ensures that when the connecting block 206 moves axially along the bolt 205, it can smoothly pull the end of the clamping block 202 to move synchronously, and make the clamping block 202 swing stably around the fulcrum on the connecting rod 203.

[0037] Please refer to Figures 4 to 6 The quick-release structure of the mounting mechanism 3 has also been optimized. The mounting block 307 serves as the mounting base of the mounting mechanism 3. The mounting block 307 and the constraint housing 201 are fixedly connected by welding. The welding connection ensures high strength and permanent fixation between the mounting block 307 and the constraint housing 201, avoiding loosening caused by the connection method under high temperature or vibration environments. The rotating shaft of the knob 306 passes through the mounting block 307 and is aligned with the slot 305 of the locking block 304. The rotating shaft of the knob 306 is located on the inner wall of the mounting block 307 and is rotatably connected to the mounting block 307. The locking block 304 is also rotatably connected to the lower middle part of the inner wall of the mounting block 307. The slot 305 on the locking block 304 is located exactly below the end of the rotating shaft of the knob 306. The end of the rotating shaft of the knob 306 has a protruding structure. When the knob 306 rotates... When rotated to a specific position, the protruding structure can coincide with the notch of the slot 305, thereby releasing the rotation lock on the locking block 304. The inner wall of the limiting hole 302 on the limiting block 303 is machined with a guide slope to facilitate the smooth sliding of the end of the locking block 304 into or out. The guide slope is set at the entrance of the limiting hole 302. When the locking block 304 rotates to reset, the end of the locking block 304 can automatically align and slide into the limiting hole 302 along the guide slope. The end of the locking block 304 itself has also been optimized. When the locking block 304 slides in connection with the inner wall of the limiting hole 302, the end has a wedge-shaped structure to enhance the reliability of insertion and locking. The wedge-shaped structure provides a good guiding function during insertion and can form a tighter self-locking fit with the inner wall of the limiting hole 302 after locking into place, preventing the temperature sensor 301 from accidentally coming out.

[0038] Working principle: When locking the constraint housing 201 in the fixing mechanism 2, the constraint housing 201 is first aligned and placed at the top of the support frame 1. The top of the support frame 1 has a ring structure, and the part used to support the constraint housing 201 provides the initial positioning for the constraint housing 201. At this time, the constraint housing 201 is located inside the support frame 1. A fixing block 204 is fixedly connected to the middle of the inner bottom wall of the support frame 1. A bolt 205 is threadedly connected to the inner wall of the fixing block 204. A connecting block 206 is rotatably connected to the upper part of the outer wall of the bolt 205. When locking is required, the bolt 205 is rotated. Since the bolt 205 and the fixing block 204 are threadedly connected, the rotation of the bolt 205 will drive the rotatably connected connecting block 206 to move up and down along the axis of the bolt 205 on the inner wall of the fixing block 204. Multiple connecting rods 203 are rotatably connected at equal intervals to the outer wall of the fixing block 204. Clamping blocks 202 are rotatably connected to the inner wall of the connecting rods 203. The end of the clamping block 202 rotates... The connecting block 206 is rotatably connected to the inner wall of the connecting block 206. The inner wall of the connecting block 206 and the end of the clamping block 202 are rotatably connected through a pin. When the connecting block 206 moves downward, the connecting block 206 will pull the ends of all the clamping blocks 202 downward synchronously through the pin. Since the middle part of the clamping block 202 is rotatably connected to the inner wall of the connecting rod 203, the connecting rod 203 acts as a fulcrum. When the end of the clamping block 202 is pulled downward, the head end of the clamping block 202 will swing inward around the rotation point on the connecting rod 203. The inner wall of the head end of the clamping block 202 is provided with an arc-shaped groove to improve the contact area with the outer wall of the constraint shell 201 and the clamping stability. The arc-shaped groove of the clamping block 202 tightens inward and finally clamps the outer wall of the constraint shell 201, forming a stable multi-point ring connection. By setting a fixing mechanism 2 inside the support frame 1, the constraint shell 201 can be prevented from shifting or deforming in high temperature or vibration environment, ensuring the structural integrity during long-term use.

[0039] When disassembling the temperature sensor 301, the temperature sensor 301 is fixedly connected to the top wall of the limiting block 303. The limiting block 303 is installed on the outer wall of the mounting block 307, which is fixedly connected to the left side of the outer wall of the constraint housing 201 by welding. In the locked state, the locking block 304 is rotatably connected to the lower part of the inner wall of the mounting block 307. The end of the locking block 304 is slidably connected to the inner wall of the limiting hole 302 opened on the outer wall of the limiting block 303. The end of the locking block 304 has a wedge-shaped structure to enhance the reliability of insertion and locking. The end of the locking block 304 is locked inside the limiting hole 302, restricting the limiting block 303 and preventing it from being removed from the mounting block 307. At this time, the knob 306, which is rotatably connected to the inner wall of the mounting block 307, passes through the mounting block 307 and aligns with the slot 305 of the locking block 304. The end of the knob 306's rotating shaft is locked on the outer wall of the locking block 304, preventing the locking block 304 from rotating freely. When disassembly is required, first rotate the knob 306 so that the end of the knob 306's rotating shaft is aligned with the locking block. When the slots 305 on the outer wall of 304 coincide, the rotational limit of the knob 306 on the locking block 304 is released, and the locking block 304 gains the freedom of rotation. Then, the locking block 304 is rotated, causing it to rotate within the inner wall of the mounting block 307. The end of the locking block 304 rotates within the limiting hole 302 and eventually slides out from the inner wall of the limiting hole 302. The inner wall of the limiting hole 302 is machined with a guide slope to facilitate the smooth sliding in and out of the end of the locking block 304. The guide slope helps the end of the locking block 304 slide out. After the end of the locking block 304 slides completely out of the limiting hole 302, the limiting effect of the locking block 304 on the limiting block 303 is released. At this time, the limiting block 303, together with the temperature sensor 301 fixed thereon, can be easily removed from the mounting block 307. By setting the mounting mechanism 3 on the outer wall of the constraint housing 201, the temperature sensor 301 can be quickly disassembled and installed, which greatly improves the maintenance efficiency of the temperature sensor 301 and prevents the temperature sensor 301 from affecting the normal use of the equipment due to inconvenient disassembly.
