Description

Technical Field

[0001] This utility model belongs to the field of plasma stove technology, specifically relating to a burner structure for a plasma stove. Background Technology

[0002] Plasma cooktops, also known as electric flame cooktops, are a new type of flame generation method. They use a high-frequency changing electric field, where two electrodes generate an electric arc under a certain voltage. The electric arc is a beam of high-temperature ionized gas, and the electric flame cooktop uses the continuous electric arc as energy for heating the pot.

[0003] For example, the existing Chinese patent with announcement number CN222417577U discloses a high-efficiency electric flame stove burner head, including a burner head top plate, a gas collection box, multiple flame outlet pipes disposed on the burner head top plate, multiple ceramic tubes corresponding to the flame outlet pipes and disposed on the bottom plate of the gas collection box, and an anode needle disposed on the bottom wall of the ceramic tubes.

[0004] Regarding the aforementioned technologies, the inventors have discovered at least the following problems: Existing electric flame stove burners generally adopt a split structure, with the plasma flame tube resting on the ceramic tube. The burner head fixing cover ultimately presses the flame tube firmly against the ceramic tube, thus fixing the entire burner head. This design aims to facilitate disassembly and maintenance of the burner head later. However, there is a lack of limiting measures between the flame tube and the ceramic tube. During later maintenance, when the burner head fixing cover is lifted, the flame tube resting on the ceramic tube is easily touched by the burner head fixing cover and falls off the ceramic tube, reducing the efficiency of burner head maintenance. Furthermore, the fallen flame tube is easily lost, causing unnecessary trouble. Utility Model Content

[0005] The purpose of this invention is to provide a burner structure for a plasma stove to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a burner head structure for a plasma stove, comprising a mica heat insulation plate, a plasma flame injector, and a burner head fixing cover. The plasma flame injector is installed between the mica heat insulation plate and the burner head fixing cover. The plasma flame injector includes a telescopic probe, an ignition needle, a ceramic tube, and a flame injector. The ignition needle is disposed at the upper end of the telescopic probe. The ceramic tube is sleeved on the ignition needle. The flame injector is sleeved on the upper end of the ceramic tube. The burner head fixing cover abuts against the outside of the flame injector.

[0007] A limiting groove is provided on one side of the ceramic tube, and a through hole is provided on one side of the flame tube. A limiting rod adapted to the limiting groove is slidably installed in the through hole.

[0008] In a preferred embodiment, the mica heat insulation plate is provided with an air inlet pipe, and an air intake fan is installed inside the air inlet pipe.

[0009] In a preferred embodiment, the ceramic tube has inclined ventilation holes on its sidewall.

[0010] In a preferred embodiment, a handle is fixedly connected to one end of the limiting rod.

[0011] In a preferred embodiment, a ceramic anti-slip sleeve is fitted onto the surface of the limiting rod, and the ceramic anti-slip sleeve abuts against the limiting rod and the inner wall of the through hole.

[0012] In a preferred embodiment, a guide block is provided on one side of the ceramic tube, and a guide groove adapted to the guide block is provided on the inner side of the lower end of the flame tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The burner head structure of this plasma stove, through the setting of limiting grooves, through holes, limiting rods and handles, allows the flame tube to be first fitted onto the upper end of the ceramic tube when assembling the plasma flame components. Then, the limiting rod is controlled by the handle to slide along the through hole, so that one end of the limiting rod is inserted into the limiting groove. This can limit the flame tube and the ceramic tube to each other. In later maintenance, when the burner head fixing cover is lifted, the flame tube will not fall off the ceramic tube due to the contact of the burner head fixing cover, avoiding the loss of the flame tube and reducing unnecessary trouble.

[0015] The burner head structure of this plasma stove, through the cooperation of the guide block and the guide groove, allows the guide groove to be aligned with the guide block and fitted onto the ceramic tube when the flame tube is connected, which facilitates the guidance of the flame tube and ensures that the through hole is aligned with the limiting groove, making subsequent operations convenient.

Detailed Implementation

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-3 This utility model provides a burner head structure for a plasma stove, including a mica heat insulation plate 1, a plasma flame injector 2, and a burner head fixing cover 3. The plasma flame injector 2 is installed between the mica heat insulation plate 1 and the burner head fixing cover 3. The plasma flame injector 2 includes a telescopic probe 21, an ignition needle 22, a ceramic tube 23, and a flame tube 24. The ignition needle 22 is located at the upper end of the telescopic probe 21, the ceramic tube 23 is sleeved on the ignition needle 22, and the flame tube 24 is sleeved on the upper end of the ceramic tube 23. The burner head fixing cover 3 abuts against the outside of the flame tube 24. The mica heat insulation plate 1 is provided with an air inlet pipe 11, and an air inlet fan 12 is installed inside the air inlet pipe 11. Inclined ventilation holes 231 are opened on the side wall of the ceramic tube 23. With the setting of the plasma flame element 2, the air inlet fan 12 can be activated to blow air into the burner head fixing cover 3 during operation. The air enters the ceramic tube 23 through the ventilation hole 231, and the ignition needle 22 ionizes the air to generate a flame that is ejected from the flame tube 24.

[0023] Reference Figure 1 and Figure 3 A limiting groove 25 is provided on one side of the ceramic tube 23, and a through hole 26 is provided on one side of the flame tube 24. A limiting rod 27 adapted to the limiting groove 25 is slidably installed in the through hole 26. A handle 28 is fixedly connected to one end of the limiting rod 27. With the setting of the limiting groove 25, through hole 26, limiting rod 27 and handle 28, when assembling the plasma flame component 2, the flame tube 24 is first put on the upper end of the ceramic tube 23, and then the limiting rod 27 is controlled to slide along the through hole 26 by the handle 28, so that the limiting rod 27 is slidable along the through hole 26, thereby limiting the flame tube 24. One end of the rod 27 is inserted into the limiting groove 25, thereby limiting the flame tube 24 and the ceramic tube 23 to each other. During later maintenance, when the furnace head fixing cover 3 is lifted, the flame tube 24 will not fall off the ceramic tube 23 due to the contact of the furnace head fixing cover 3, thus avoiding the loss of the flame tube 24 and reducing unnecessary trouble. When it is necessary to disassemble the flame tube 24 of a certain plasma flame component 2 separately, the limiting rod 27 can be pulled out from the limiting groove 25 by the handle 28, and the flame tube 24 can be removed.

[0024] Furthermore, a ceramic anti-slip sleeve 29 is fitted onto the surface of the limiting rod 27. The ceramic anti-slip sleeve 29 abuts against the inner wall of the through hole 26. By setting the ceramic anti-slip sleeve 29, the friction between the limiting rod 27 and the inner wall of the through hole 26 can be increased, preventing the limiting rod 27 from becoming too loose and sliding out of the through hole 26, thereby improving the stability of the limiting rod 27.

[0025] Furthermore, a guide block 210 is provided on one side of the ceramic tube 23, and a guide groove adapted to the guide block 210 is opened on the inner side of the lower end of the flame tube 24. Through the cooperation of the guide block 210 and the guide groove, when the flame tube 24 is fitted, the guide groove can be aligned with the guide block 210 and fitted onto the ceramic tube 23, which facilitates the guidance of the flame tube 24 and allows the through hole 26 to be aligned with the limiting groove 25, which facilitates subsequent operations.

[0026] The working principle and usage process of this utility model are as follows: First, when assembling the plasma flame component 2, align the guide groove with the guide block 210, and first put the flame tube 24 on the upper end of the ceramic tube 23 to facilitate the guidance of the flame tube 24, so that the through hole 26 can be aligned with the limiting groove 25. Then, control the limiting rod 27 to slide along the through hole 26 through the handle 28, so that one end of the limiting rod 27 is inserted into the limiting groove 25, thereby limiting the flame tube 24 and the ceramic tube 23 to each other. During later maintenance, when the furnace head fixing cover 3 is lifted, the flame tube 24 will not fall off the ceramic tube 23 due to the contact of the furnace head fixing cover 3, avoiding the loss of the flame tube 24 and reducing unnecessary trouble. When it is necessary to disassemble the flame tube 24 of a certain plasma flame component 2 separately, the limiting rod 27 can be pulled out from the limiting groove 25 through the handle 28, and the flame tube 24 can be removed.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
