Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, specifically to a burner assembly and a stove. Background Technology

[0002] Currently, the burners of tabletop cooktops are typically one-piece structures, and ignition usually uses open flame ignition. Specifically, a flame tube is connected to the valve body assembly, with the flame nozzle facing the burner head. An ignition needle is positioned near the flame nozzle. When the ignition switch is pressed, the electric spark generated by the ignition needle ignites the gas mixture near the flame nozzle. The flame is then sprayed along the axis of the flame nozzle towards the burner head, and guided by a guide on the burner head (located below the burner cap) to the burner cap's flame holes for ignition. However, because the burner head is one-piece molded, the cost is relatively high. Utility Model Content

[0003] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a burner assembly is provided, the technical solution of which is as follows.

[0004] The burner assembly includes a burner and an igniter. The burner has a support frame, an injector, a flame distribution seat, and a flame cap. The injector is positioned by the support frame. The flame cap and the flame distribution seat enclose a mixing chamber, which is connected to the injector. The igniter is located outside the outer ring of the flame cap. The support frame and the flame distribution seat are separate and located below the flame distribution seat. The support frame has an ignition plate, which is opposite to the igniter.

[0005] The burner assembly of this utility model has two aspects. First, the support frame and the flame distribution seat are set separately, so that the burner head is at least partially constructed as a split structure, which reduces the cost compared with the integral cast burner head. Second, the support frame has an ignition plate body, which is located below the flame distribution seat and opposite to the igniter. Thus, the ignition plate body can guide the flame sprayed by the igniter to the flame hole of the burner cap to achieve ignition, thus meeting the ignition requirements.

[0006] For example, the support frame also has a support plate with mounting holes, through which the ejector tube passes. The support plate and the ignition plate are an integral structure; or, the support plate and the ignition plate are separate structures. This configuration facilitates positioning the ejector tube within the support plate. Furthermore, when the support plate and the ignition plate are an integral structure, they are integrally formed and can be formed by stamping or bending, facilitating manufacturing. When the support plate and the ignition plate are separate structures, the ignition plate can be installed or removed from the support plate, facilitating cleaning or maintenance.

[0007] Exemplarily, the flame distributor base has a base bottom wall, and the projection of the ignition plate body onto the plane where the base bottom wall is located is within the base bottom wall. With such a setting, it can ensure that the ignition plate body guides the flame ejected by the igniter to the flame holes of the burner cap, and reduces the space occupied by the burner.

[0008] The ignition plate body has an ignition wall. The ignition wall has a far edge away from the support plate body and a connection edge opposite to the far edge. The flame distributor base has a base bottom wall, and the far edge is connected or abutted to the base bottom wall. With such a setting, the far edge is located below the base bottom wall. The flame ejected by the igniter towards the ignition wall can reduce the flame passing through below the base bottom wall. The ignition wall can guide more flames to the flame holes of the burner cap, improving the ignition efficiency, and can reduce the flames wandering below the base bottom wall, thereby reducing the burning hazard of the flames to the components below the base bottom wall, and further improving the lifespan of the burner.

[0009] Exemplarily, the igniter has a flame ejection port. The flame ejected through the flame ejection port forms a flame ejection area on the ignition wall. The flame ejection area has a length L1, and the ignition wall has a length L2, where L1 < L2; and / or, in the axial direction of the central axis of the flame distributor base, the connection edge is lower than the flame ejection port. With such a setting, not only can it prevent the flame ejected from the flame ejection port to the ignition wall from overflowing from both sides of the ignition wall, enabling the ignition wall to guide more flames to the flame holes of the burner cap, but also it can ensure that the ignition wall guides the flame ejected by the flame ejection port to the flame holes of the burner cap, thereby improving the ignition efficiency, and can reduce the flames wandering below the base bottom wall, thereby reducing the burning hazard of the flames to the components below the base bottom wall, and further improving the lifespan of the burner.

[0010] Exemplarily, the support plate body and the ignition plate body are of a split structure. The ignition plate body further has a first connection wall connected to the support plate body and / or a second connection wall connected to the base bottom wall. With such a setting, when the ignition plate body further has a first connection wall connected to the support plate body, it can ensure that the support plate body supports the ignition plate body and improves the connection stability between the ignition plate body and the support plate body; when the ignition plate body further has a second connection wall connected to the base bottom wall, it can ensure that the ignition plate body guides the flame ejected by the igniter to the flame holes of the burner cap and improves the connection stability between the ignition plate body and the base bottom wall; when the ignition plate body further has a first connection wall connected to the support plate body and a second connection wall connected to the base bottom wall, it can not only ensure that the ignition plate body guides the flame ejected by the igniter to the flame holes of the burner cap, improves the connection stability between the ignition plate body and the base bottom wall, but also can ensure that the support plate body supports the ignition plate body and improves the connection stability between the ignition plate body and the support plate body.

[0011] For example, the ignition plate body also has a first connecting wall, which is connected to the connecting edge, and the first connecting wall has an adjacent edge adjacent to the connecting edge, and the adjacent edge is connected to an enclosing wall. With this configuration, the first connecting wall is connected to the supporting plate body, which can ensure that the supporting plate body supports the ignition plate body, improve the stability of the connection between the ignition plate body and the base wall, and improve the structural strength of the ignition plate body.

[0012] For example, the side of the enclosing wall away from the first connecting wall is connected to or abuts against the base wall; or, the ignition plate body also has a second connecting wall, which is connected to the side of the enclosing wall away from the first connecting wall. This arrangement, where the side of the enclosing wall away from the first connecting wall is connected to or abuts against the base wall, improves the stability of the connection between the ignition plate body and the base wall, and also increases the structural strength of the ignition plate body; the second connecting wall being connected to the side of the enclosing wall away from the first connecting wall, and thus connecting to the base wall, not only facilitates the connection between the ignition plate body and the base wall, further improving the stability of the connection between the ignition plate body and the base wall, but also further improving the structural strength of the ignition plate body.

[0013] For example, the ignition plate body further includes a first reinforcing member, one end of which is connected to the ignition wall and the other end of which is connected to the first connecting wall; and / or, the first connecting wall is provided with a first through hole; and / or, the first connecting wall is provided with a second through hole, a first flange is formed around the second through hole, the inner wall surface of the first flange is formed with threads, the support plate body is provided with a first fixing hole, and fasteners are connected to the first fixing hole and the second through hole by thread engagement; and / or, the ignition plate body is provided with a strip hole, part of which is provided on the ignition wall and part of which is provided on the first connecting wall. This design, by incorporating reinforcing components, not only enhances the stability of the connection between the first connecting wall and the ignition wall but also further improves the structural strength of the ignition plate. The first through-hole allows liquids flowing from or spilling from the cookware to drain when the burner assembly is used in the stove, preventing corrosion of the ignition plate due to prolonged liquid accumulation. The fasteners, passing through the first fixing hole and the second through-hole and threadedly connected, not only ensure the stability of the connection between the first connecting wall and the support plate but also facilitate installation or disassembly for cleaning or maintenance. Finally, the strip-shaped holes allow liquids flowing from or spilling from the cookware to drain when the burner assembly is used in the stove, preventing corrosion of the ignition plate due to prolonged liquid accumulation.

[0014] For example, the ignition plate body also has a first connecting wall and a second connecting wall, the first connecting wall being connected to the connecting edge and the second connecting wall being connected to the distance edge. This arrangement ensures that the ignition plate body guides the flame ejected by the igniter to the flame hole of the flame cap, improving the stability of the connection between the ignition plate body and the support plate body, and also improving the stability of the connection between the ignition plate body and the base wall.

[0015] For example, the support plate and the ignition plate are an integral structure, with the connecting edge connected to the support plate and a second connecting wall connected to the base wall away from the edge. This configuration ensures that the ignition plate guides the flame ejected by the igniter to the flame hole of the flame cap, improves the stability of the connection between the ignition plate and the base wall, and has a simple structure that is easy to manufacture.

[0016] For example, the support plate includes a first plate portion and a second plate portion, which are connected and located on different planes to form a step. A mounting hole is provided on the first plate portion, and the ignition plate body is connected to, abuts against, or has a gap with the second plate portion. This arrangement, with the first and second plate portions on different planes forming a step, not only ensures that the first plate portion supports the ejector tube, but also facilitates the connection, abutment, or gap between the ignition plate body and the second plate portion. When the ignition plate body is connected to or abuts against the second plate portion, the second plate portion can be guaranteed to support the ignition plate body, thus expanding the application range of the support plate body.

[0017] For example, the support plate also includes a third plate portion connected to the side of the first plate portion away from the second plate portion, and the third plate portion and the first plate portion are located on different planes to form a step. With this configuration, when the burner assembly is applied to the stove, the third plate portion and the first plate portion are located on different planes to form a step, which facilitates the connection of the third plate portion to the crossbeam body.

[0018] For example, the second plate portion extends away from the first plate portion on the side that bends away from the burner seat to form a second flange; and / or, the third plate portion extends away from the first plate portion on the side that bends away from the burner seat to form a third flange. With this configuration, when the second flange is provided, interference with the connection between the ignition plate and the second plate portion is avoided, and the structural strength of the second plate is strengthened; when the third flange is provided, when the burner assembly is applied to the stove, interference with the connection between the support plate and the crossbeam is avoided, and the structural strength of the third plate is strengthened; when both the second and third flanges are provided, not only is interference with the connection between the ignition plate and the second plate portion avoided by the second flange, strengthening the structural strength of the second plate, but also, when the burner assembly is applied to the stove, interference with the connection between the support plate and the crossbeam is avoided by the third flange, strengthening the structural strength of the third plate.

[0019] For example, the periphery of the first plate extends in a bend away from the burner seat, with multiple extensions. The second plate is connected to the first plate via one of these extensions. Among the multiple extensions is a relative extension opposite to the first plate. The third plate is connected to the second plate via the relative extension. This configuration facilitates the connection between the second plate and the ignition plate body when the burner assembly is applied to the stove, facilitates the connection between the third plate and the crossbeam body, and strengthens the structural strength of the supporting plate body.

[0020] According to another aspect of this utility model, a stove is provided, which includes a housing and a burner assembly as described above. The housing encloses a receiving cavity, and at least one crossbeam is disposed within the receiving cavity. At least a portion of the burner is located within the receiving cavity. The support frame also has a support plate, which is connected to at least one crossbeam. Since the burner assembly described above has the aforementioned beneficial effects, the stove including the burner assembly described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0021] For example, the accommodating cavity is provided with two crossbeams, and the support plate has a second plate portion and a third plate portion. The second plate portion is engaged or threadedly connected to one of the two crossbeams, and the third plate portion is engaged or threadedly connected to the other of the two crossbeams. This arrangement ensures that the burner is supported and facilitates the fixed connection between the support plate and the crossbeams.

Detailed Implementation

[0040] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0041] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0042] This invention provides a burner assembly. The burner assembly of this invention can be applied to stoves. The following will describe in detail one embodiment of the burner assembly according to the accompanying drawings.

[0043] See also Figures 1 to 11 The burner assembly may include a burner 10 and an igniter 20. The burner 10 may have a support frame 110, an injector 120, a burner seat 130, and a burner cap 140. The injector 120 can be positioned by the support frame 110. The burner cap 140 and the burner seat 130 can enclose a mixing chamber 150. The mixing chamber 150 can communicate with the injector 120. It should be noted that the burner cap 140 can be annular, and the annular burner cap 140 can have an outer ring 142 and an inner ring 143. The igniter 20 can be located outside the outer ring 142 of the burner cap 140, so that the burner 10 can meet the requirements of a tabletop stove. The burner cap 140 may be provided with flame holes 141, which allow the gas and air in the mixing chamber 150 to mix in a certain proportion to form a good combustible mixture. The support frame 110 can be separately installed from the burner seat 130 and can be located below the burner seat 130. The support frame 110 can have an ignition plate 112, and the ignition plate 112 can be opposite to the igniter 20. Specifically, the igniter 20 sprays a flame toward the ignition plate 112, and the flame is guided along the ignition plate 112 to the burner seat 130, and then from the burner seat 130 to the flame hole 141 of the burner cap 140. The flame ignites the combustible mixture, thereby achieving ignition. When the ejector tube 120 is positioned by the support frame 110 and the support frame 110 and the burner seat 130 are separately installed, the burner head of the burner 10 has a split structure. The support frame 110, ejector tube 120, and burner seat 130 can be made of stainless steel, making the entire burner head a stainless steel burner head. This avoids rusting due to oil corrosion over time, and the stainless steel burner head is lighter than a one-piece cast burner head, which also reduces processing and installation costs. Of course, the support frame 110, ejector tube 120, fire seat 130 and fire cap 140 can be made entirely or partially of stainless steel to suit different application scenarios.

[0044] The burner assembly of this utility model has two aspects. First, the support frame 110 and the flame distribution seat 130 are separately set, so that the burner head is at least partially constructed as a split structure, which reduces the cost compared with the integral cast burner head. Second, the support frame 110 has an ignition plate 112, which is located below the flame distribution seat 130 and opposite to the igniter 20. Thus, the ignition plate 112 can guide the flame sprayed by the igniter 20 to the flame hole 141 of the burner cap 140 to achieve ignition, thus meeting the ignition requirements.

[0045] See Figure 11The support frame 110 also has a support plate 111, on which mounting holes 1111 can be formed. The ejector tube 120 can pass through the mounting holes 1111. The support plate 111 and the ignition plate 112 can be an integral structure. Thus, the support plate 111 and the ignition plate 112 can be formed by stamping or bending, which is convenient for processing and manufacturing.

[0046] See also Figures 2 to 10 The support frame 110 also has a support plate 111, on which mounting holes 1111 can be formed. The ejector tube 120 can pass through the mounting holes 1111. The support plate 111 and the ignition plate 112 can be separate structures. In this way, the ignition plate 112 can be installed or removed relative to the support plate 111, which is convenient for cleaning or maintenance.

[0047] In one embodiment of this utility model, in conjunction with reference to Figures 4 to 8The ejector tube 120 may include an inner ring ejector tube 121 and an outer ring ejector tube 122. The mounting hole 1111 may include a first hole 1111a and a second hole 1111b. The first hole 1111a and the second hole 1111b may be spaced apart on the support plate 111. A first positioning boss 1211 may be provided on the outer wall of the inner ring ejector tube 121. The inner ring ejector tube 121 may be divided into a first tube segment 1212 and a second tube segment 1213 by the first positioning boss 1211. The first tube segment 1212 may pass through the first hole 1111a and be located above the support plate 111, while the second tube segment 1213 may be located below the support plate 111. The first positioning boss 1211 may be connected to the support plate 111. Specifically, the first positioning boss 1211 may be welded to the support plate 111. Alternatively, the first positioning boss 1211 may be connected to the support plate 111 by means of adhesive or screws. The outer ring ejector tube 122 passes through the second hole 1111b. A second positioning boss 1221 may be provided on the outer wall of the outer ring ejector tube 122. The outer ring ejector tube 122 can be divided into a third tube segment 1222 and a fourth tube segment 1223 through the second positioning boss 1221. The third tube segment 1222 can pass through the second hole 1111b and be located above the support plate 111, while the fourth tube segment 1223 can be located below the support plate 111. The second positioning boss 1221 can be connected to the support plate 111. Specifically, the second positioning boss 1221 can be welded to the support plate 111. Of course, the second positioning boss 1221 can also be connected to the support plate 111 by means of adhesive or screws. Thus, the inner ring ejector tube 121 is connected to the support plate 111 through the first positioning boss 1211, and the outer ring ejector tube 122 is connected to the support plate 111 through the second positioning boss 1221. This avoids the phenomenon of deformation or air leakage of the inner ring ejector tube 121 and the outer ring ejector tube 122 due to direct connection between the outer wall of the inner ring ejector tube 121 and the outer wall of the outer ring ejector tube 122 and the support plate 111.

[0048] See also Figures 2 to 6 The ignition base 130 has a base wall 131, and the projection of the ignition plate 112 onto the plane of the base wall 131 can be located within the base wall 131. Specifically, the ignition wall 1121 can be perpendicular to the base wall 131. This ensures that the ignition plate 112 guides the flame ejected by the igniter 20 to the flame hole 141 of the burner cap 140, and reduces the space occupied by the burner 10. Of course, it is also possible that the ignition wall 1121 forms an angle with the base wall 131.

[0049] See again Figures 2 to 6The ignition plate 112 may have an ignition wall 1121. The ignition wall 1121 may have a remote side 1121a and a connecting side 1121b. The remote side 1121a is located away from the support plate 111, and the connecting side 1121b is opposite to the remote side 1121a. The burner seat 130 has a base wall 131, and the remote side 1121a is connected to or abuts against the base wall 131. Thus, the remote side 1121a is located below the base wall 131. The flame sprayed by the igniter 20 toward the ignition wall 1121 can reduce the flame passing under the base wall 131. The ignition wall 1121 can guide more flame to the flame hole 141 of the burner cap 140, improving ignition efficiency and reducing the flame wandering under the base wall 131, thereby mitigating the scorching damage to the components below the base wall 131 and improving the life of the burner 10.

[0050] See also Figure 3 and Figure 6 The outer edge of the burner 10, away from edge 1121a and base wall 131, can have a distance D, which can be 0mm to 7mm, for example, 0mm, 2mm, 4mm, 7mm, etc. When the distance D is within this range, the efficiency of the ignition wall 1121 in guiding the flame to the flame hole 141 of the burner cap 140 is high, improving ignition efficiency and reducing the flame wandering below the base wall 131, thereby mitigating the scorching damage to components below the base wall 131 and improving the lifespan of the burner 10. A distance D greater than this range should be avoided, as this would cause the flame injected by the igniter 20 onto the ignition wall 1121 to be blocked by the base wall 131 and unable to be guided to the flame hole 141 of the burner cap 140. A distance D less than this range should also be avoided, as this would create a gap between the ignition wall 1121 and the base wall 131, preventing the flame injected by the igniter 20 onto the ignition wall 1121 from being guided to the flame hole 141 of the burner cap 140. In one embodiment of this utility model, the spacing D can be 7mm. The ignition wall 1121 guides the flame to the fire hole 141 of the fire cover 140 with high efficiency, which improves the ignition efficiency and reduces the flame wandering below the base wall 131, thereby reducing the burning damage to the components below the base wall 131 caused by the flame, and thus improving the life of the burner 10.

[0051] Further, the ignition wall 1121 can form an angle with the bottom wall 131, and the projection of the ignition wall 1121 onto the plane where the bottom wall 131 is located can be at least partially within the bottom wall 131. Specifically, within the range of the distance D between the far edge 1121a and the outer edge of the bottom wall 131, the ignition wall 1121 can be inclined from the far edge 1121a towards the outer ring 142 of the burner cap 140, thus enhancing the guiding effect of the ignition wall 1121. Within the range of the distance D between the far edge 1121a and the outer edge of the bottom wall 131, the ignition wall 1121 is inclined from the far edge 1121a towards the inner ring 143 of the burner cap 140, thus saving the space occupied by the burner 10. Within the range of the distance D between the far edge 1121a and the outer edge of the bottom wall 131, the ignition wall 1121 can be perpendicular to the bottom wall 131, thus ensuring the ignition effect of the ignition wall 1121 and saving the space occupied by the burner 10.

[0052] Referring to Figure 2 、 Figure 3 and Figure 5 ,the igniter 20 can have a flame ejection port 210. The flame ejected through the flame ejection port 210 can form a flame ejection area 1122 on the ignition wall 1121. The flame ejection area 1122 can have a length L1, and the ignition wall 1121 can have a length L2, where L1 < L2. That is, in the length direction, the flame ejection area 1122 is located within the ignition wall 1121. In this way, it is avoided that the flame ejected from the flame ejection port 210 to the ignition wall 1121 overflows from both sides of the ignition wall 1121, enabling the ignition wall 1121 to guide more flames to the flame holes 141 of the burner cap 140, improving the ignition efficiency, and reducing the flames wandering under the bottom wall 131, thereby reducing the burning hazard to the components under the bottom wall 131 caused by the flames, and further improving the lifespan of the burner 10.

[0053] Referring to Figure 2 and Figure 3 ,the igniter 20 can have a flame ejection port 210, and the ignition wall 1121 can have a connecting edge 1121b opposite to the far edge 1121a. In the direction of the central axis of the flame dividing base 130, the connecting edge 1121b can be lower than the flame ejection port 210. In this way, it can be ensured that the ignition wall 1121 guides the flame ejected from the flame ejection port 210 to the flame holes 141 of the burner cap 140, and reduces the flames wandering under the bottom wall 131, thereby reducing the burning hazard to the components under the bottom wall 131 caused by the flames, and further improving the lifespan of the burner 10. It should be noted that the lower the connecting edge 1121b is than the flame ejection port 210, the more flames are ejected from the flame ejection port 210 onto the ignition wall 1121, and it is more capable of reducing the flames wandering under the bottom wall 131, thereby reducing the burning hazard to the components under the bottom wall 131 caused by the flames.

[0054] Referring to Figure 2 、 Figure 3 and Figure 5 , the igniter 20 may have a flame ejection port 210. The flame ejected through the flame ejection port 210 may form a flame ejection area 1122 on the ignition wall 1121. The flame ejection area 1122 may have a length L1, and the ignition wall 1121 may have a length L2, where L1 < L2; in the axial direction of the fire distribution base 130, the connecting edge 1121b may be lower than the flame ejection port 210. In this way, not only can the flame ejected from the flame ejection port 210 to the ignition wall 1121 be prevented from overflowing from both sides of the ignition wall 1121, enabling the ignition wall 1121 to guide more flames to the fire holes 141 of the burner cap 140, but also it can ensure that the ignition wall 1121 guides the flame ejected from the flame ejection port 210 to the fire holes 141 of the burner cap 140, thereby improving the ignition efficiency and reducing the flames wandering under the bottom wall 131, thus reducing the burning hazard to the components under the bottom wall 131 and further increasing the lifespan of the burner 10.

[0055] Referring to Figure 2 、 Figure 9 and Figure 10 , the support plate body 111 and the ignition plate body 112 are of a split structure, and the ignition plate body 112 further has a first connecting wall 1123 connected to the support plate body 111. The first connecting wall 1123 and the ignition wall 1121 may be of an integral structure, which is convenient for processing and manufacturing. The first connecting wall 1123 and the ignition wall 1121 may also be of a split structure, which is convenient for installation or disassembly, thus facilitating cleaning or maintenance. In this way, it can ensure that the support plate body 111 supports the ignition plate body 112 and improves the stability of the connection between the ignition plate body 112 and the support plate body 111.

[0056] Referring to Figure 2 、 Figure 10 and Figure 11 , the support plate body 111 and the ignition plate body 112 are of a split structure, and the ignition plate body 112 further has a second connecting wall 1128 connected to the bottom wall 131. In this way, it can ensure that the ignition plate body 112 guides the flame ejected by the igniter 20 to the fire holes 141 of the burner cap 140 and improves the stability of the connection between the ignition plate body 112 and the bottom wall 131.

[0057] Referring to Figure 2 、 Figure 9 and Figure 10The support plate 111 and the ignition plate 112 are separate structures. The ignition plate 112 also has a first connecting wall 1123 connected to the support plate 111 and a second connecting wall 1128 connected to the base wall 131. In this way, it can not only ensure that the ignition plate 112 guides the flame sprayed by the igniter 20 to the flame hole 141 of the flame cap 140, improving the stability of the connection between the ignition plate 112 and the base wall 131, but also ensure that the support plate 111 provides support for the ignition plate 112, and improve the stability of the connection between the ignition plate 112 and the support plate 111.

[0058] See again Figure 2 and Figure 9 The ignition plate body 112 also has a first connecting wall 1123, which can be connected to the connecting edge 1121b. The first connecting wall 1123 can have an adjacent edge 1123a adjacent to the connecting edge 1121b, and the adjacent edge 1123a can be connected to an enclosing wall 1124. Specifically, there can be two enclosing walls 1124, which can be respectively connected to two adjacent edges 1123a of the first connecting wall 1123. The first connecting wall 1123 and the enclosing wall 1124 can be an integral structure for easy manufacturing. Alternatively, the first connecting wall 1123 and the enclosing wall 1124 can be separate structures for easy installation or disassembly, thus facilitating cleaning or maintenance. Thus, the first connecting wall 1123 is connected to the support plate 111, which ensures that the support plate 111 supports the ignition plate 112, improves the stability of the connection between the ignition plate 112 and the base wall 131, and improves the structural strength of the ignition plate 112.

[0059] For example, the side of the enclosing wall 1124 away from the first connecting wall 1123 can be connected to or abut against the base wall 131. Specifically, the side of the enclosing wall 1124 away from the first connecting wall 1123 can be spot-welded to the base wall 131 to avoid uneven gas distribution in the mixing chamber 150 due to damage to the base wall 131. Of course, the side of the enclosing wall 1124 away from the first connecting wall 1123 and the base wall 131 can also be connected by other methods, such as bonding. In this way, the stability of the connection between the ignition plate 112 and the base wall 131 is improved, and the structural strength of the ignition plate 112 is also improved.

[0060] See again Figure 2 and Figure 9, the ignition plate body 112 further has a second connecting wall 1128, and the second connecting wall 1128 is connected to the side of the enclosing wall 1124 away from the first connecting wall 1123. Specifically, the second connecting wall 1128 can be spot-welded to the seat bottom wall 131 to avoid uneven gas distribution in the mixing chamber 150 due to damage to the seat bottom wall 131. Of course, the second connecting wall 1128 and the seat bottom wall 131 can also be connected by other connection methods, such as pasting. The number of the second connecting walls 1128 can correspond to the number of the enclosing walls 1124. When the number of the enclosing walls 1124 is two, the number of the second connecting walls 1128 can be two, and the two second connecting walls 1128 can extend in directions away from each other on their respective corresponding enclosing walls 1124 to facilitate the processing of other parts of the ignition plate body 112. Thus, the second connecting wall 1128 is connected to the side of the enclosing wall 1124 away from the first connecting wall 1123. When the second connecting wall 1128 is connected to the seat bottom wall 131, it not only facilitates the connection between the ignition plate body 112 and the seat bottom wall 131, further improving the connection stability between the ignition plate body 112 and the seat bottom wall 131, but also further improves the structural strength of the ignition plate body 112.

[0061] Referring in combination to Figure 2 , Figure 5 and Figure 9 , a gap S is formed between the remote edge 1121a and the seat bottom wall 131, where 0 mm < S ≤ 1 mm. For example, the gap S can be 0.2 mm, 0.5 mm, 0.7 mm, 1 mm, etc. Thus, when the gap S is within this range, it can ensure that the ignition wall 1121 guides the flame ejected by the igniter 20 to the flame holes 141 of the burner cap 140, avoiding the phenomenon that the remote edge 1121a abuts against the seat bottom wall 131 and causing the distributor seat 130 to tilt due to too small gap S, and avoiding the flame passing through the gap due to too large gap S, reducing the ignition effect. In an embodiment of the present invention, the gap S can be 1 mm, which can ensure that the ignition wall 1121 guides the flame ejected by the igniter 20 to the flame holes 141 of the burner cap 140.

[0062] Referring in combination again to Figure 2 and Figure 9 , the ignition plate body 112 can further include a first reinforcing member 1125. One end of the first reinforcing member 1125 can be connected to the ignition wall 1121, and the other end can be connected to the first connecting wall 1123. The first reinforcing member 1125 can be a reinforcing rib. Thus, it not only enhances the connection stability between the first connecting wall 1123 and the ignition wall 1121, but also further improves the structural strength of the ignition plate body 112. The number of the first reinforcing members 1125 is not specifically limited herein as long as it can improve the structural strength of the ignition plate body 112.

[0063] Referring in combination again to Figure 2 and Figure 9 A first through hole 1123b may be provided on the first connecting wall 1123. Thus, when the burner assembly is applied to the stove for cooking, liquid flowing or spilling from the pot can flow out through the first through hole 1123b, preventing corrosion of the ignition plate 112 due to prolonged liquid accumulation. Furthermore, the number of first through holes 1123b can be one or more, to quickly drain liquid from the ignition plate 112.

[0064] See again Figure 2 , Figure 5 and Figure 9 A second through hole 1123c can be provided on the first connecting wall 1123. A first flange 1123d can be formed around the second through hole 1123c, and a thread (not shown in the figure) can be formed on the inner wall surface of the first flange 1123d. That is, the second through hole 1123c can be a flanged tapping hole. The support plate 111 can be provided with a first fixing hole 1112. Fasteners are connected by threaded engagement through the first fixing hole 1112 and the second through hole 1123c. The fasteners can be screws or bolts, etc. The fasteners can pass through the first fixing hole 1112 and the second through hole 1123c in sequence and then be connected by threaded engagement. It should be noted that the second through hole 1123c and the first fixing hole 1112 can be located between the inner ring ejector tube 121 and the outer ring ejector tube 122 to avoid the inner ring ejector tube 121 or the outer ring ejector tube 122 interfering with the installation of the ignition plate 112. Thus, by connecting the fasteners through the first fixing hole 1112 and the second through hole 1123c with threads, not only is the stability of the connection between the first connecting wall 1123 and the support plate 111 ensured, but installation and disassembly are also convenient for cleaning or maintenance. Of course, the first connecting wall 1123 and the support plate 111 can also be connected by other methods, such as snap-fit ​​connections or welding. Furthermore, the number of second through holes 1123c can be one or more to enhance the stability of the connection between the first connecting wall 1123 and the support body. The number of first fixing holes 1112 corresponds to the number of second through holes 1123c.

[0065] See again Figure 2 and Figure 9 The ignition plate 112 may be provided with strip-shaped holes 1126, a portion of which may be located on the ignition wall 1121 and a portion on the first connecting wall 1123. Thus, when the burner assembly is applied to the stove for cooking, liquid flowing from or spilling from the pot can flow out through the strip-shaped holes 1126, preventing corrosion of the ignition plate 112 due to prolonged liquid accumulation. Furthermore, the number of strip-shaped holes 1126 may be one or more, to quickly drain liquid from the ignition plate 112.

[0066] See again Figure 2 and Figure 9 The ignition plate 112 may further include a second reinforcing member 1127, one end of which can be connected to the enclosing wall 1124 and the other end to the first connecting wall 1123. The second reinforcing member 1127 may be a reinforcing rib. When there are two enclosing walls 1124, there can be two second reinforcing members 1127, with each second reinforcing member 1127 corresponding to one enclosing wall 1124. This not only enhances the stability of the connection between the first connecting wall 1123 and the enclosing wall 1124, but also further improves the structural strength of the ignition plate 112. Of course, the number of second reinforcing members 1127 may also be one or more, as long as it can improve the structural strength of the ignition plate 112.

[0067] See also Figure 2 and Figure 10 The ignition plate 112 may also have a first connecting wall 1123 and a second connecting wall 1128. The first connecting wall 1123 can be connected to the connecting edge 1121b, and the second connecting wall 1128 can be connected to the edge away from 1121a. The first connecting wall 1123 can be connected to the support plate 111, and the second connecting wall 1128 can be connected to the base wall 131. That is, the cross-section of the ignition plate 112 can be C-shaped. The ignition wall 1121, the first connecting wall 1123, and the second connecting wall 1128 can be an integral structure for easy processing and manufacturing. The ignition wall 1121, the first connecting wall 1123, and the second connecting wall 1128 can also be separate structures for easy installation or disassembly, thus facilitating cleaning or maintenance. The first connecting wall 1123 can be connected to the support plate 111 by spot welding or adhesive bonding. The second connecting wall 1128 can be connected to the base wall 131 by screws or welding. In this way, the ignition plate 112 can guide the flame sprayed by the igniter 20 to the flame hole 141 of the flame cap 140, which improves the stability of the connection between the ignition plate 112 and the support plate 111, and also improves the stability of the connection between the ignition plate 112 and the base wall 131.

[0068] In an embodiment not shown in the figure, one, two or more drain holes may be provided on the first connecting wall 1123, so that when the burner assembly is applied to the stove for cooking, liquid flowing out or spilling from the pot can be drained out, preventing corrosion of the ignition plate 112 due to long-term accumulation of liquid.

[0069] In an embodiment not shown in the figure, the ignition plate 112 may further include a first reinforcing rib and a second reinforcing rib. One end of the first reinforcing rib may be connected to the first connecting wall 1123, and the other end may be connected to the ignition wall 1121. One end of the second reinforcing rib may be connected to the second connecting wall 1128, and the other end may be connected to the ignition wall 1121. This not only enhances the stability of the connections between the first connecting wall 1123 and the ignition wall 1121, and between the second connecting wall 1128 and the ignition wall 1121, but also further improves the structural strength of the ignition plate 112. Of course, the ignition plate 112 may also include either the first reinforcing rib or the second reinforcing rib, expanding the application scenarios. The number of the first and second reinforcing ribs is not specifically limited here, as long as it can improve the structural strength of the ignition plate 112.

[0070] See also Figure 2 and Figure 11 The support plate 111 and the ignition plate 112 are an integral structure. The connecting edge 1121b can be connected to the support plate 111, and the edge away from 1121a can be connected to the second connecting wall 1128. The second connecting wall 1128, the ignition wall 1121, and the support plate 111 can be an integral structure, which is convenient for processing and manufacturing and saves costs. The second connecting wall 1128 and the ignition wall 1121 can be separate structures, which is convenient for installation or disassembly, thus facilitating cleaning or maintenance. In this way, it can be ensured that the ignition plate 112 guides the flame sprayed by the igniter 20 to the flame hole 141 of the flame cap 140, which improves the stability of the connection between the ignition plate 112 and the base wall 131, and the structure is simple and easy to process.

[0071] In an embodiment not shown in the figure, the ignition plate 112 may further include a third reinforcing rib, one end of which may be connected to the second connecting wall 1128 and the other end of which may be connected to the ignition wall 1121. This not only enhances the stability of the connection between the second connecting wall 1128 and the ignition wall 1121, but also further improves the structural strength of the ignition plate 112.

[0072] In an embodiment not shown in the figure, the ignition plate 112 may further include a fourth reinforcing rib, one end of which may be connected to the support plate 111 and the other end of which may be connected to the ignition wall 1121. This not only enhances the stability of the connection between the support plate 111 and the ignition wall 1121, but also further improves the structural strength of the support plate 111 and the ignition plate 112.

[0073] In an embodiment not shown in the figure, the ignition wall 1121, the enclosing wall 1124, the first connecting wall 1123, and the second connecting wall 1128 can also be enclosed to form an enclosure with an opening on one side. The ignition plate 112 can also be in the shape of a sheet, a square prism, or a triangular prism. It is sufficient that the ignition plate 112 guides the flame ejected by the igniter 20 to the flame hole 141 of the flame cap 140 to meet the ignition requirements.

[0074] In some embodiments, the support plate 111 can be a plate structure parallel to the ignition base 130, which can not only support the ejector tube 120, but also connect to the ignition plate 112. It has a simple structure and is easy to process and manufacture.

[0075] See also Figure 2 , Figure 12 and Figure 13 The support plate 111 may include a first plate portion 1113 and a second plate portion 1114. The first plate portion 1113 may be connected to the second plate portion 1114, and the first plate portion 1113 and the second plate portion 1114 may be located on different planes to form a step. A mounting hole 1111 may be provided on the first plate portion 1113. The ignition plate 112 may be connected to, abut against, or have a gap with the second plate portion 1114. Understandably, the first hole 1111a and the second hole 1111b may be provided on the first plate portion 1113. Specifically, the second plate portion 1114 may be farther away from the ignition base 130 than the first plate portion 1113. Of course, the second plate portion 1114 may also be closer to the ignition base 130 than the first plate portion 1113. The interval between the second plate portion 1114 and the first plate portion 1113 is related to the distance between the second plate portion 1114 and the ignition base 130, so that the support plate 111 can be adapted to different scenarios. Thus, the first plate portion 1113 and the second plate portion 1114 are located on different planes to form a step, which not only ensures that the first plate portion 1113 supports the ejector tube 120, but also facilitates the connection, contact, or gap between the ignition plate body 112 and the second plate portion 1114. When the ignition plate body 112 and the second plate portion 1114 are connected or contacted, the second plate portion 1114 can support the ignition plate body 112, thus expanding the application range of the support plate body 111.

[0076] In some embodiments, when the ignition plate 112 has a first connecting wall 1123, the first connecting wall 1123 is connected to the second plate portion 1114. Specifically, the second plate portion 1114 and the first connecting wall 1123 can be connected by fasteners, and the second plate portion 1114 can be provided with a first fixing hole 1112. The fasteners pass through the first fixing hole 1112 and the second through hole 1123c of the first connecting wall 1123 and are threaded together. The fasteners can be screws or bolts, etc. The fasteners can pass through the first fixing hole 1112 and the second through hole 1123c in sequence and then be threaded together. Of course, the first connecting wall 1123 and the second plate portion 1114 can also be connected by welding or snap-fit ​​connection, etc. In this way, on the one hand, the ignition plate 112 can guide the flame sprayed by the igniter 20 to the flame hole 141 of the flame cap 140, and on the other hand, the second plate 1114 can support the ignition plate 112, thereby indirectly supporting the flame distribution seat 130.

[0077] In some embodiments, when the ignition wall 1121 is connected to the support plate 111, the ignition wall 1121 and the second plate portion 1114 can be an integral structure to facilitate manufacturing and save costs. Alternatively, the ignition wall 1121 and the second plate portion 1114 can be separate structures for easier cleaning and maintenance. This ensures that, on the one hand, the ignition wall 1121 guides the flame ejected from the igniter 20 to the flame hole 141 of the flame cap 140; on the other hand, it ensures that the second plate portion 1114 supports the ignition wall 1121, thereby indirectly supporting the flame distribution seat 130.

[0078] In one embodiment of this utility model, a first flanged hole 1113c and a second flanged hole 1113d may be provided on the first plate portion 1113. The first flanged hole 1113c and the second flanged hole 1113d may be disposed between the first hole 1111a and the second hole 1111b, and a thermocouple 160 may be disposed on either the first flanged hole 1113c or the second flanged hole 1113d. Specifically, the thermocouple 160 may be disposed on the first flanged hole 1113c. In this way, on the one hand, the connection between the thermocouple 160 and the first plate portion 1113 is enhanced by connecting the first flanged hole 1113c and the thermocouple 160; on the other hand, when the burner assembly is applied to the stove for cooking, liquid flowing out or spilling from the pot can flow out through the second flanged hole 1113d, preventing corrosion of the first plate portion 1113 due to prolonged accumulation of liquid.

[0079] See also Figure 12 and Figure 13The side of the second plate portion 1114 away from the first plate portion 1113 can be bent and extended in a direction away from the ignition seat 130 to form a second flange 1114a. In this way, the second flange 1114a is prevented from interfering with the connection between the ignition plate body 112 and the second plate portion 1114, and the structural strength of the second plate body is strengthened.

[0080] See again Figure 12 and Figure 13 A third through hole 1114b may be provided on the second plate portion 1114. Thus, when the burner assembly is used in a stove for cooking, liquid flowing or spilling from the pot can flow out through the third through hole 1114b, preventing corrosion of the support plate 111 due to prolonged liquid accumulation. Specifically, when the ignition plate 112 is the embodiment described above with a first through hole 1123b, the first through hole 1123b can be positioned opposite to the third through hole 1114b, ensuring that liquid can flow from the first through hole 1123b through the third through hole 1114b to the outside, preventing corrosion of the ignition plate 112 and the support plate 111 due to prolonged liquid accumulation.

[0081] In an embodiment not shown in the figure, the number of third through holes 1114b can be one, two, or more, to more quickly drain the liquid on the second plate portion 1114. Specifically, when the number of third through holes 1114b is two, it not only speeds up the drainage of liquid from the ignition plate 112, but also ensures the structural strength of the second plate.

[0082] See again Figure 2 , Figure 12 and Figure 13 The support plate 111 may further include a third plate portion 1115, which may be connected to the side of the first plate portion 1113 away from the second plate portion 1114, and the third plate portion 1115 and the first plate portion 1113 are located on different planes to form a step. Thus, when the burner assembly is applied to the stove, the third plate portion 1115 and the first plate portion 1113 are located on different planes to form a step, which facilitates the connection of the third plate portion 1115 to the crossbeam 40.

[0083] See again Figure 2 , Figure 12 and Figure 13A locking part 1115a may be provided on the third plate 1115. It should be noted that the burner 10 may also have a nozzle tube 320. The end of the ejector tube 120 away from the support plate 111 is connected to a damper plate 170. The damper plate 170 is connected to the nozzle tube 320. A spring 330 may be provided at the connection between the damper plate 170 and the nozzle tube 320. After the nozzle tube 320 is connected to the ejector tube 120, the spring 330 is compressed and applies a spring force to the ejector tube 120 away from the nozzle tube 320. Therefore, when the burner 10 is installed on the stove, it can first be locked with the locking engagement part 410 of the crossbeam 40 through the locking part 1115a, so that the ejector tube 120 is positioned by the support plate 111, and the ejector tube 120 is prevented from moving by the spring force applied by the spring 330, so that the support plate 111 and the crossbeam 40 can be fixedly connected. Thus, when the burner assembly is applied to the stove, the third plate 1115 and the first plate 1113 are spaced apart along the central axis of the burner seat 130, which facilitates the connection between the third plate 1115 and the crossbeam 40. The locking part 1115a engages with the locking engagement part 410 on the crossbeam 40 to position the support plate 111, thereby facilitating the fixed connection between the support plate 111 and the crossbeam 40.

[0084] See again Figure 2 , Figure 12 and Figure 13 The side of the third plate portion 1115 away from the first plate portion 1113 can be bent and extended toward the burner seat 130 to form a third flange 1115b. In this way, when the burner assembly is applied to the stove, the third flange 1115b is prevented from interfering with the connection between the support plate 111 and the crossbeam 40, and the structural strength of the third plate is strengthened.

[0085] See again Figure 2 , Figure 12 and Figure 13 The second plate portion 1114, on the side away from the first plate portion 1113, can be bent and extended in a direction away from the burner base 130 to form a second flange 1114a. The third plate portion 1115, on the side away from the first plate portion 1113, can be bent and extended in a direction towards the burner base 130 to form a third flange 1115b. In this way, not only is the second flange 1114a prevented from interfering with the connection between the ignition plate body 112 and the second plate portion 1114, thus strengthening the structural strength of the second plate body, but also, when the burner assembly is applied to the stove, the third flange 1115b is prevented from interfering with the connection between the support plate body 111 and the crossbeam body 40, thus strengthening the structural strength of the third plate body.

[0086] See also Figure 2 and Figure 12A first through hole 1115c can be provided on the third plate portion 1115, and a fourth flange can be formed around the first through hole 1115c. The fourth flange can be configured as a locking part 1115a. That is to say, the first through hole 1115c can be a flange hole. In this way, on the one hand, when the burner assembly is applied to the stove, the fourth flange engages with the locking part 410 on the crossbeam 40 to position the support plate 111, and the structure is simple and easy to process and manufacture; on the other hand, when the burner assembly is applied to the stove for cooking, liquid flowing out or spilling from the pot can flow out through the first through hole 1115c, preventing corrosion of the third plate portion 1115 due to long-term accumulation of liquid.

[0087] See also Figure 2 and Figure 13 The third plate portion 1115 may be provided with a second through hole 1115d, and a portion of the hole wall of the second through hole 1115d may extend outward to form a locking portion 1115a. In this way, on the one hand, when the burner assembly is applied to the stove, the locking portion 1115a engages with the locking engagement portion 410 on the crossbeam 40 to position and support the plate 111, and the structure is simple and easy to manufacture; on the other hand, when the burner assembly is applied to the stove for cooking, liquid flowing out or spilling from the pot can flow out through the second through hole 1115d, preventing corrosion of the third plate portion 1115 due to long-term accumulation of liquid.

[0088] See again Figure 2 , Figure 12 and Figure 13 The periphery of the first plate portion 1113 can be bent and extended in a direction away from the burner seat 130, with multiple extensions 1113a. The second plate portion 1114 can be connected to the first plate portion 1113 through one of the extensions 1113a. Among the multiple extensions 1113a, there may be a corresponding extension 1113b opposite to the first plate portion 1113. The third plate portion 1115 can be connected to the second plate portion 1114 through the corresponding extension 1113b. It should be noted that the extension 1113a can be a flange of the first plate portion 1113. In this way, when the burner assembly is applied to the stove, it is beneficial for the second plate portion 1114 to be connected to the ignition plate body 112, and for the third plate portion 1115 to be connected to the crossbeam body 40, and the structural strength of the supporting plate body 111 is strengthened. The third plate 1115 can be spaced apart from the first plate 1113. The distance between the third plate 1115 and the first plate 1113 is related to the position of the crossbeam 40, so that the support plate 111 can be adapted to different scenarios. Of course, the first plate 1113 and the second plate 1114, and the first plate 1113 and the third plate 1115 can also be connected by other structures, such as blocks or strips.

[0089] See again Figure 2 , Figure 12 and Figure 13 The third plate 1115 may have a fourth through hole 1115e, and a fifth flange 1115f may be formed around the fourth through hole 1115e. The inner wall of the fifth flange 1115f may be threaded. That is to say, the fourth through hole 1115e can be a flanged tapping hole. Fasteners can pass through the second fixing hole 420 and the fourth through hole 1115e in sequence, and then be connected with the threads. In this way, when the burner assembly is applied to the stove, the connection between the support plate 111 and the crossbeam 40 is further strengthened by fasteners passing through the second fixing hole 420 of the crossbeam 40 and the fourth through hole 1115e of the third plate 1115 and being connected with the threads, and the installation or disassembly is convenient, and cleaning or maintenance is easy. The fasteners can be screws or bolts, etc. Of course, the third plate 1115 and the crossbeam 40 can also be connected by other connection methods, such as snap-fit ​​connection or welding. Furthermore, the number of fourth through holes 1115e can be multiple to enhance the stability of the connection between the third plate portion 1115 and the crossbeam body 40. Specifically, the number of fourth through holes 1115e can be two, which not only enhances the stability of the connection between the third plate portion 1115 and the crossbeam body 40, but also facilitates processing and saves costs. The number of second fixing holes 420 corresponds to the number of fourth through holes 1115e.

[0090] In one embodiment of this utility model, the nozzle tube 320 may be connected to a valve body assembly 310, and the valve body assembly 310 may also be connected to an igniter 20. The igniter 20 may also include an ignition needle 220, which may be positioned close to the flame port 210. After pressing the ignition switch, the electric spark generated by the ignition needle 220 ignites the gas mixture near the flame port 210, and the flame is sprayed along the central axis of the flame port 210 toward the ignition plate 112. The flame is guided to the flame hole 141 of the flame cap 140 by the ignition plate 112.

[0091] According to another aspect of this utility model, a stove is provided. (See also...) Figure 1The stove may include a housing and a burner assembly as described above. The housing may enclose a cavity, within which at least one crossbeam 40 may be disposed. At least a portion of the burner 10 may be located within the cavity. The support frame 110 further includes a support plate 111, which may be connected to at least one crossbeam 40. Understandably, the crossbeam 40 may be used to support the burner 10. Specifically, the stove may be constructed as a tabletop stove, which can be placed directly on a stovetop and moved freely for convenient cooking. The tabletop stove may also employ open flame ignition. Since the burner assembly described above has the aforementioned beneficial effects, the stove including the burner assembly described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0092] See also Figure 1 , Figure 12 and Figure 13 The accommodating cavity is provided with two crossbeams 40. The support plate 111 has a second plate portion 1114 and a third plate portion 1115. The second plate portion 1114 is engaged or threadedly connected to one of the two crossbeams 40, and the third plate portion 1115 is engaged or threadedly connected to the other of the two crossbeams 40. In this way, the burner 10 can be supported, and the support plate 111 can be easily fixedly connected to the crossbeams 40.

[0093] See again Figure 1 , Figure 12 and Figure 13 The support plate 111 may have a third plate portion 1115, on which a locking portion 1115a may be provided. The crossbeam 40 may have a locking engagement portion 410, and the locking portion 1115a may engage with the locking engagement portion 410. The locking engagement portion 410 may be a connecting hole or a groove. Thus, the locking portion 1115a engages with the locking engagement portion 410 to position the support plate 111, thereby facilitating the fixed connection between the support plate 111 and the crossbeam 40.

[0094] See again Figure 1 , Figure 12 and Figure 13 The third plate 1115 may also be provided with a fourth through hole 1115e. A fifth flange 1115f may be formed around the fourth through hole 1115e, and the inner wall of the fifth flange 1115f may be threaded. A second fixing hole 420 may be provided on the crossbeam 40. Fasteners are connected by passing through the second fixing hole 420 and the fourth through hole 1115e and engaging with the thread. In this way, the connection between the support plate 111 and the crossbeam 40 is further strengthened by fasteners passing through the second fixing hole 420 and the fourth through hole 1115e and engaging with the thread, and the connection is convenient for installation or disassembly, cleaning or maintenance.
