Technical Field

[0001] This utility model relates to the field of stoves, and in particular to a burner and a stove including the burner. Background Technology

[0002] In stoves, the burner head with top air intake is often removable for easy cleaning. To make the structure of the burner head more robust, the burner cap and mixing chamber are often fixed in place.

[0003] In existing technologies, the burner cap and mixing chamber are typically fixed using screw connections or interference fits. Screw connections are suitable for structures with thicker materials, but their application conditions are limited, and the structure is also more complex. With interference fit connections, the large area of ​​interference between the burner cap and mixing chamber can easily lead to abnormal noises due to alternating hot and cold temperatures. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the burner head structure being relatively complex and prone to abnormal noise in the prior art, and to provide a burner and a stove containing the burner.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A burner includes a burner cap and a mixing chamber, both the burner cap and the mixing chamber having an inner ring and an outer ring, the inner ring of the burner cap being mounted on top of the inner ring of the mixing chamber, and the lower end face of the outer ring of the burner cap being supported on top of the outer ring of the mixing chamber and sealingly connected to the top end face of the outer ring of the mixing chamber.

[0007] The outer ring of the burner cap is fitted with the outer ring of the mixing chamber with a clearance, and multiple fasteners are connected between the outer ring of the burner cap and the outer ring of the mixing chamber.

[0008] The fasteners are spaced apart along the circumferential direction of the outer ring of the fire cap.

[0009] In this design, the outer ring of the burner cap and the outer ring of the mixing chamber are fitted with a clearance. Multiple fasteners connect the outer ring of the burner cap and the outer ring of the mixing chamber. Different connection or fitting methods are adopted according to different structural parts, which helps to simplify the structure of the burner head and also helps to reduce abnormal noise.

[0010] Preferably, the top of the outer ring of the mixing chamber has a first stepped portion, and the lower end face of the outer ring of the burner cap is supported on the first stepped portion and sealed to the first stepped portion.

[0011] In this design, the above-mentioned structural configuration allows the first step to provide some support and initial positioning for the outer ring of the burner cap, which helps to ensure the reliability of the connection between the burner cap and the mixing chamber.

[0012] Preferably, the outer ring of the burner cap has a plurality of first connecting holes spaced apart in the circumferential direction, the outer ring of the mixing chamber has a plurality of second connecting holes spaced apart in the circumferential direction, and the fastener is a semi-knurled pin.

[0013] One of the knurled portion and the smooth portion of the semi-knurled pin is installed in the first connecting hole, and the other is installed in the second connecting hole.

[0014] Preferably, one of the first connecting hole and the second connecting hole is a through hole and the other is a blind hole.

[0015] Preferably, the first connecting hole is a through hole, the second connecting hole is a blind hole, the knurled portion of the semi-knurled pin is embedded in the second connecting hole, and the smooth portion of the semi-knurled pin is inserted into the first connecting hole.

[0016] In this design, the knurled part of the semi-knurled pin is embedded into the mixing chamber through the second connecting hole, which provides a more secure fixation. The smooth part of the semi-knurled pin engages with the outer ring of the burner cap through the first connecting hole. The friction between the smooth part and the burner cap surface is small, which reduces the friction during thermal expansion and contraction, making the positioning more reliable.

[0017] Preferably, a plurality of first connecting holes are evenly arranged along the side wall of the outer ring of the burner cap, and a plurality of second connecting holes are evenly arranged along the side wall of the outer ring of the mixing chamber.

[0018] In this design, the multiple first connection holes and multiple second connection holes are evenly arranged, and the connection positions are evenly distributed, which helps to improve the reliability of the connection between the burner cap and the mixing chamber.

[0019] Preferably, the inner ring of the burner cap is interference-fitted with the inner ring of the mixing chamber.

[0020] In this design, the inner diameters of the burner cap and the inner diameter of the mixing chamber are relatively small, resulting in a relatively small contact area between them. The use of an interference fit can reduce the risk of abnormal noise while ensuring a seal.

[0021] Preferably, the top of the inner ring of the mixing chamber has a second step, and the lower end face of the inner ring of the burner cap is supported on the second step.

[0022] In this design, the above-mentioned structural configuration allows the second step to provide some support and initial positioning for the inner ring of the burner cap, which helps ensure the reliability of the connection between the burner cap and the mixing chamber.

[0023] Preferably, a cushioning material is filled between the burner cap and the mixing chamber.

[0024] In this solution, the above-mentioned structural design, with the addition of cushioning material, can further reduce abnormal noises and improve the user experience.

[0025] This utility model also provides a stove, which includes the above-mentioned burner.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] In this application, the outer ring sidewall of the burner cap and the outer ring sidewall of the mixing chamber are fitted with a clearance, and multiple fasteners are connected between the outer ring sidewall of the burner cap and the outer ring sidewall of the mixing chamber. Different connection or fitting methods are adopted according to different structural parts, which helps to simplify the structure of the burner head and also helps to reduce abnormal noise.

[0046] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0047] like Figures 1 to 6 As shown, this embodiment provides a burner and a stove including the burner. The burner includes a burner cap 10 and a mixing chamber 20. Both the burner cap 10 and the mixing chamber 20 have an inner ring and an outer ring. The inner ring 102 of the burner cap is installed on top of the inner ring 202 of the mixing chamber. The lower end face of the outer ring 101 of the burner cap is supported on top of the outer ring 201 of the mixing chamber and is sealed to the top end face of the outer ring 201 of the mixing chamber. The side wall of the outer ring 101 of the burner cap and the side wall of the outer ring 201 of the mixing chamber are clearance-fitted, and a plurality of fasteners are connected between the side wall of the outer ring 101 of the burner cap and the side wall of the outer ring 201 of the mixing chamber. The plurality of fasteners are spaced apart along the circumferential direction of the outer ring 101 of the burner cap.

[0048] In this embodiment, the side wall of the outer ring 101 of the burner cap and the side wall of the outer ring 201 of the mixing chamber are fitted with a clearance. Multiple fasteners are connected between the side wall of the outer ring 101 of the burner cap and the side wall of the outer ring 201 of the mixing chamber. Different connection or fitting methods are adopted according to different structural parts, which helps to simplify the structure of the burner head and also helps to reduce abnormal noise.

[0049] It should be noted that the specific detailed structure of the burner cap 10 and the mixing chamber 20 and their corresponding working principles are not the main improvement direction of this application. This application mainly focuses on how the burner cap 10 and the mixing chamber 20 are specifically matched and connected. As for the specific detailed structure of the burner cap 10 and the mixing chamber 20 and their corresponding working principles, those skilled in the art should be familiar with them, and will not be elaborated here.

[0050] like Figures 3 to 5 As shown, the top of the outer ring 201 of the mixing chamber has a first step portion 203, and the lower end face of the outer ring 101 of the burner cap is supported on the first step portion 203 and sealed to the first step portion 203.

[0051] With the above configuration, the first step 203 can provide some support and initial positioning for the outer ring 101 of the burner cap, which helps to ensure the reliability of the connection between the burner cap 10 and the mixing chamber 20.

[0052] like Figures 3 to 6 As shown, the outer ring 101 of the burner cap has a plurality of first connecting holes 30 spaced apart in the circumferential direction, and the outer ring 201 of the mixing chamber has a plurality of second connecting holes 40 spaced apart in the circumferential direction. As a preferred implementation, the fastener is a semi-knurled pin 50.

[0053] In this case, one of the knurled portion and the smooth portion of the semi-knurled pin 50 is installed in the first connecting hole 30, and the other is installed in the second connecting hole 40.

[0054] To further simplify the structure and optimize the burner's performance, one of the first connecting hole 30 and the second connecting hole 40 is a through hole and the other is a blind hole.

[0055] Specifically, in this embodiment, such as Figure 3 and Figure 5 As shown, the first connecting hole 30 is a through hole, the second connecting hole 40 is a blind hole, the knurled part of the semi-knurled pin 50 is inserted into the second connecting hole 40, and the smooth part of the semi-knurled pin 50 is inserted into the first connecting hole 30.

[0056] Among them, the knurled part of the semi-knurled pin 50 is embedded into the mixing chamber 20 through the second connecting hole 40, and is fixed relatively firmly. The smooth part of the semi-knurled pin 50 is engaged with the outer ring 101 of the flame cap through the first connecting hole 30. The friction between the smooth part and the surface of the flame cap 10 is small, which reduces the friction during thermal expansion and contraction, making the positioning more reliable.

[0057] In other alternative embodiments, the first connecting hole 30 may be configured as a blind hole, while the second connecting hole 40 may be configured as a through hole.

[0058] It should be noted that the number of the first connecting hole 30 and the second connecting hole 40 is not limited here and can be adapted according to actual needs. For example, as shown... Figure 6 As shown, there are four first connecting holes 30 and four second connecting holes 40.

[0059] In addition, in other alternative embodiments, the fastener may be configured with other structures, not limited to the semi-rolling pin 50 of this application.

[0060] To further improve the reliability of the connection, the plurality of first connection holes 30 are arranged evenly along the side wall of the outer ring 101 of the burner cap, and the plurality of second connection holes 40 are arranged evenly along the side wall of the outer ring 201 of the mixing chamber.

[0061] With this configuration, the multiple first connection holes 30 and multiple second connection holes 40 are evenly distributed, and the connection positions are uniformly distributed, which helps to improve the reliability of the connection between the burner cap and the mixing chamber 20.

[0062] Furthermore, in this embodiment, the inner ring 102 of the burner cap and the inner ring 202 of the mixing chamber are interference-fitted. Since the inner rings 102 and 202 of the mixing chamber have relatively small diameters and a relatively small contact area, the interference fit ensures a tight seal while reducing the risk of abnormal noise.

[0063] Reference Figures 3 to 5 It is understood that the top of the inner ring 202 of the mixing chamber has a second step 204, and the lower end face of the inner ring 102 of the burner cap is supported on the second step 204. The second step 204 can provide a certain degree of support and initial positioning for the inner ring 102 of the burner cap, which helps to ensure the reliability of the connection between the burner cap and the mixing chamber 20.

[0064] Furthermore, a cushioning material is filled between the burner cap 10 and the mixing chamber 20. The specific material and filling location of the cushioning material are not limited here, and can be adapted to actual design requirements.

[0065] By filling the holes with cushioning material, abnormal noises can be further reduced, which helps to improve the user experience.

[0066] In summary, in this embodiment, the outer ring sidewall of the burner cap and the outer ring sidewall of the mixing chamber are clearance-fitted, and multiple fasteners connect the outer ring sidewall of the burner cap and the outer ring sidewall of the mixing chamber. Different connection or fit methods are adopted according to different structural parts, which helps to simplify the structure of the burner head and also helps to reduce abnormal noise. The inner ring 102 of the burner cap and the inner ring 202 of the mixing chamber are interference-fitted. The inner ring 102 of the burner cap and the inner ring 202 of the mixing chamber have small diameters and relatively small contact areas. The interference fit can reduce the risk of abnormal noise while ensuring sealing. In addition, the fastener is specifically set as a semi-knurled pin 50. The smooth part of the semi-knurled pin 50 fits with the outer ring 101 of the burner cap through the first connecting hole 30. The friction between the smooth part and the surface of the burner cap 10 is small, which reduces the friction during thermal expansion and contraction, making the positioning more reliable.

[0067] It should be noted that the stove can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the stove to perform corresponding operations, thereby realizing intelligent control of the stove and improving the user experience.
