Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, and in particular to a smoke baffle assembly, a machine head and an integrated stove. Background Art

[0002] Integrated stoves are kitchen appliances that combine multiple functions, including a range hood, gas stove, disinfection cabinet, and storage cabinet. They offer advantages such as space saving, effective fume extraction, energy saving, low consumption, and environmental protection. However, these stoves often produce considerable noise when extracting fume. Existing integrated stoves typically incorporate noise reduction components within the fume collection chamber to mitigate this noise. However, these components are difficult to remove due to their location within the fume collection chamber, making cleaning and replacement of the noise reduction pads extremely challenging. Utility Model Content

[0003] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, a smoke damper assembly is provided. The smoke damper assembly includes a smoke damper, a first noise reduction member, and a second noise reduction member. The first noise reduction member is detachably connected to the smoke damper. When connected to the smoke damper, the first noise reduction member forms an accommodating cavity between the first noise reduction member and the smoke damper. The second noise reduction member is disposed within the accommodating cavity. The first noise reduction member, the second noise reduction member, and the smoke damper are integrally connected.

[0004] The smoke damper assembly provided by the present invention has a first noise reduction member that is detachably connected to the smoke damper, and a second noise reduction member that is disposed in a receiving cavity between the first noise reduction member and the smoke damper. The first noise reduction member and the second noise reduction member can reduce the noise generated when the smoke damper assembly is used to absorb oil smoke. The first noise reduction member can rotate with the smoke damper, so that the second noise reduction member located in the receiving cavity can also rotate with the smoke damper. Furthermore, the first noise reduction member is detachably connected to the smoke damper, so that the smoke damper can be rotated to a position that facilitates the removal of the first noise reduction member. The connection between the first noise reduction member and the smoke damper is then removed, allowing both the first noise reduction member and the second noise reduction member to be removed, thereby making the cleaning, repair, or replacement of the first noise reduction member and the second noise reduction member simpler and more convenient.

[0005] For example, the first noise reduction member includes a connecting portion and an enclosing portion. The connecting portion has an opening, the enclosing portion is connected to the periphery of the opening, and the enclosing portion is recessed away from the smoke shield. The connecting portion is threadedly connected to the smoke shield, and the smoke shield blocks the opening to form a receiving cavity between the enclosing portion and the smoke shield. The connecting portion is threadedly connected to the smoke shield, making the connection between the first noise reduction member and the smoke shield easier to disassemble, and also making it easier to connect the first noise reduction member to the smoke shield. Such an easy disassembly of the first noise reduction member further simplifies the disassembly and assembly of the second noise reduction member, making the smoke shield assembly easier to install and disassemble, and making it easier to clean, repair, or replace the first and second noise reduction members.

[0006] Exemplarily, the enclosure includes an enclosure bottom plate and an enclosure side plate. One end of the enclosure side plate is connected to the periphery of the enclosure bottom plate, and the other end is connected to the connection portion. The enclosure bottom plate is spaced apart by the enclosure side plate and the connection portion. The enclosure bottom plate is provided with a plurality of sound-absorbing holes, and the accommodating cavity is connected to the outside through the plurality of sound-absorbing holes. The plurality of sound-absorbing holes provided on the enclosure bottom plate allow sound waves to enter the accommodating cavity through the plurality of sound-absorbing holes, thereby achieving a better noise reduction effect for the second noise reduction member within the accommodating cavity. Furthermore, the plurality of sound-absorbing holes can achieve small-hole sound absorption, thereby achieving a better noise reduction effect for the first noise reduction member and the second noise reduction member as a whole.

[0007] For example, the enclosing side panels include a first connecting panel and a second connecting panel. The first connecting panel is attached to the connecting portion and surrounds the opening, and the second connecting panel is connected between the enclosing bottom panel and the first connecting panel. With such enclosing side panels connected around the opening, the contact area between the enclosing portion and the connecting portion can be increased, thereby making the connection between the enclosing portion and the connecting portion more stable and improving the stability of the overall device.

[0008] According to another aspect of the present invention, a machine head is provided. The machine head includes a machine head body and a smoke shield assembly as described above. The machine head body and the smoke shield enclose a smoke collecting chamber. The first noise reduction member and the second noise reduction member are located in the smoke collecting chamber. The smoke shield is rotatable between an open position and a closed position relative to the machine head body. When the first noise reduction member and the second noise reduction member are located in the smoke collecting chamber, the overall noise reduction effect of the first noise reduction member and the second noise reduction member can be better. When such a machine head is disassembled, the smoke shield can be rotated to the open position relative to the machine head body, so that the disassembly of the first noise reduction member and the second noise reduction member exposed outside the machine head can naturally be simpler and more convenient.

[0009] For example, the first noise reduction member includes a first magnet, a first magnetic member is disposed within the smoke collection chamber, and the first magnetic member is connected to the handpiece body. When the smoke shield is in a closed position relative to the handpiece body, the first magnetic member and the first magnet form a magnetic engagement. After the smoke shield is rotated relative to the handpiece body to the closed position, the first magnet and the first magnetic member automatically form a magnetic engagement. When the smoke shield needs to be rotated relative to the handpiece body to the open position, the external force required is not very large, thereby making the overall device more convenient to disassemble, install, and use.

[0010] Exemplarily, the first noise reduction component includes a connecting portion and an enclosure portion. The connecting portion has an opening. The enclosure portion is connected around the opening and is recessed away from the smoke shield. The connecting portion is threadedly connected to the smoke shield. The smoke shield blocks the opening and forms a receiving cavity between the enclosure portion. The first magnet is disposed on the connecting portion. The smoke shield can still be similar to a conventional smoke shield by disposing the first magnet on the connecting portion. This makes the production and processing of the overall device simpler and more convenient. Furthermore, the connecting portion can include a portion made of a magnetic material. The portion made of the magnetic material on the connecting portion can form the first magnet. This makes the structure of the overall device simpler and easier to implement.

[0011] Exemplarily, the enclosure portion includes an enclosure bottom plate and an enclosure side plate, the enclosure side plate is connected to the periphery of the enclosure bottom plate, the enclosure bottom plate is connected to the periphery of the opening through the enclosure side plate, a plurality of sound-absorbing holes are provided on the enclosure bottom plate, and the accommodating chamber is connected to the smoke collecting chamber through the plurality of sound-absorbing holes. Usually, when oil smoke passes through the smoke collecting chamber, a large noise is generated. The accommodating chamber is connected to the smoke collecting chamber through the plurality of sound-absorbing holes. The sound waves generated when oil smoke passes through the smoke collecting chamber can also enter the accommodating chamber through the plurality of sound-absorbing holes from the smoke collecting chamber, and the second noise reduction component in the accommodating chamber can also achieve a better noise reduction effect; and the plurality of sound-absorbing holes can achieve small-hole sound absorption. The first noise reduction component is located in the smoke collecting chamber, so that the plurality of sound-absorbing holes located in the smoke collecting chamber can achieve a better noise reduction effect through small-hole sound absorption. Such a first noise reduction component and a second noise reduction component as a whole can also achieve a better noise reduction effect.

[0012] For example, a positioning pin extending into the smoke collection chamber is provided on the handpiece body, and a hook is provided on the first noise reduction member and / or the smoke shield, which is hooked against the positioning pin when the smoke shield is in the open position relative to the handpiece body. The hook hooking against the positioning pin when the smoke shield is in the open position relative to the handpiece body ensures that the smoke shield will not fall off when the smoke shield is in the open position relative to the handpiece body, thereby maintaining the smoke shield in the open position relative to the handpiece body without applying external force. When the smoke shield is in the open position relative to the handpiece body and the first and second noise reduction members are removed, no external force is required to maintain the smoke shield in the open position relative to the handpiece body, thereby making removal of the first and second noise reduction members more convenient.

[0013] For example, a second magnetic member is provided on the handpiece body, and a second magnet is provided on the smoke shield. When the smoke shield is in a closed position relative to the handpiece body, the second magnetic member and the second magnet form a magnetic engagement. After the smoke shield is rotated relative to the handpiece body to the closed position, the second magnet and the second magnetic member automatically form a magnetic engagement. When the smoke shield needs to be rotated relative to the handpiece body to the open position, the external force required is not very large, thereby making the overall device more convenient to disassemble, install, and use.

[0014] For example, a smoke inlet is provided between the main body of the machine head and the smoke deflector, and above the smoke deflector. The smoke collection chamber is connected to the outside through the smoke inlet, and the smoke inlet is higher than the first and second noise reduction members. Thus, the oil smoke entering the smoke collection chamber through the smoke inlet will pass through the first and second noise reduction members, ensuring that all oil smoke entering the smoke collection chamber passes through the first and second noise reduction members. The first and second noise reduction members can reduce the noise of all oil smoke entering the smoke collection chamber, thereby achieving a better noise reduction effect for the entire device and reducing the noise generated.

[0015] According to another aspect of the present invention, an integrated stove is provided, comprising a main body and any one of the above-described heads, the head being connected to the main body.

[0029] In the following description, numerous details are provided to facilitate 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, and that the present invention 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.

[0030] According to one aspect of the present invention, a smoke shield assembly is provided. The smoke shield assembly can be applied to any suitable device, including but not limited to a handpiece. Therefore, according to another aspect of the present invention, a handpiece is provided. The handpiece can include a handpiece body and any of the smoke shield assemblies to be described below. The handpiece can be applied to any suitable device, including but not limited to an integrated stove. Therefore, according to yet another aspect of the present invention, an integrated stove is provided. See Figure 1 、 Figure 2 and Figure 3 The integrated stove 10 may include a body 12 and any of the heads 11 to be described below, and the head 11 may be connected to the body 12. Figure 4 The nose 11 may include a nose body 200 and a smoke shield assembly 100 .

[0031] See also Figure 5 、 Figure 6 、 Figure 7 and Figure 8The smoke damper assembly 100 may include a smoke damper 110, a first noise reducer 120, and a second noise reducer 130. The first noise reducer 120 is detachably connected to the smoke damper 110. The first noise reducer 120 may be detachably connected to the smoke damper 110 by snapping, threading, or other various forms. When the first noise reducer 120 is connected to the smoke damper 110, an accommodating cavity may be formed between the first noise reducer 120 and the smoke damper 110. The second noise reducer 130 may be disposed in the accommodating cavity, and the first noise reducer 120, the second noise reducer 130, and the smoke damper 110 may be connected as a whole. The first noise reducer 120 may have an enclosure 122, and the enclosure 122 may be recessed away from the smoke damper 110. Such a first noise reducer 120 may naturally form an accommodating cavity between the first noise reducer 120 and the smoke damper 110 when connected to the smoke damper 110. Of course, a receiving cavity can also be formed between the first noise reducing member 120 and the smoke damper 110 in various other suitable forms, which will not be elaborated here. When the second noise reducing member 130 is arranged in the receiving cavity, it is equivalent to the second noise reducing member 130 being arranged between the first noise reducing member 120 and the smoke damper 110. At this time, the connection between the first noise reducing member 120 and the smoke damper 110 is disassembled, and the first noise reducing member 120 and the second noise reducing member 130 can be disassembled and taken out respectively. The second noise reducing member 130 can be noise reducing cotton or various other forms. For the second noise reducing member 130 in the form of noise reducing cotton, such a smoke damper assembly 100 needs to remove the noise reducing cotton for cleaning or replacement after long-term use. In such a smoke damper assembly 100, since it is very simple and convenient to disassemble the second noise reducing member 130, it is also easier and more convenient to clean or replace the noise reducing cotton. The first noise reducer 120, the second noise reducer 130, and the smoke damper 110 are integrally connected, so the first noise reducer 120, the second noise reducer 130, and the smoke damper 110 can rotate synchronously. When the smoke damper assembly 100 is applied to the head 11 of the integrated stove 10, the smoke damper 110 can usually rotate relative to the head body 200. That is, after the smoke damper 110 is rotated relative to the head body 200, the first noise reducer 120 and the second noise reducer 130 can rotate with the smoke damper 110 to a position that is easier to disassemble. Then, the connection between the first noise reducer 120 and the smoke damper 110 can be disassembled and removed. In this way, the removal of the second noise reducer 130 in the smoke damper assembly 100 is simpler and more convenient.

[0032] The smoke damper assembly 100 provided by the present invention has a first noise reduction member 120 that is detachably connected to the smoke damper 110, and a second noise reduction member 130 that is disposed within a receiving chamber between the first noise reduction member 120 and the smoke damper 110. The first noise reduction member 120 and the second noise reduction member 130 can reduce noise generated when the smoke damper assembly 100 is used to absorb oil fumes. The first noise reduction member 120 can rotate with the smoke damper 110, thereby allowing the second noise reduction member 130, located within the receiving chamber, to rotate with the smoke damper 110. Furthermore, the first noise reduction member 120 is detachably connected to the smoke damper 110. Therefore, the smoke damper 110 can be rotated to a position convenient for removal of the first noise reduction member 120. The connection between the first noise reduction member 120 and the smoke damper 110 can then be removed, allowing both the first noise reduction member 120 and the second noise reduction member 130 to be removed, thereby simplifying and facilitating cleaning, repair, or replacement of the first noise reduction member 120 and the second noise reduction member 130.

[0033] In one embodiment of the present invention, see Figure 5The first noise reduction component 120 may include a connecting portion 121 and an enclosing portion 122. The connecting portion 121 may have an opening 1211. The enclosing portion 122 may be connected around the opening 1211. The connecting portion 121 and the enclosing portion 122 may be integrally formed, or the connecting portion 121 and the enclosing portion 122 may be separately processed and then connected together in various forms such as welding, clamping or threaded connection. The enclosing portion 122 may be recessed in a direction away from the smoke shield 110. The connecting portion 121 may be threadedly connected to the smoke shield 110, and the smoke shield 110 may block the opening 1211 and the enclosing portion 122 to form a receiving cavity. When the first noise reducer 120 is not yet connected to the smoke shield 110, the second noise reducer 130 can pass through the opening 1211 and enter the accommodating cavity. For the second noise reducer 130 in the form of noise reduction cotton or the like, the opening 1211 can be of any suitable size due to its excellent flexibility. When installing the smoke shield assembly 100, the second noise reducer 130 can be placed into the accommodating cavity through the opening 1211, and then the smoke shield 110 is connected to the connecting portion 121. The smoke shield 110 can then block the opening 1211, and the second noise reducer 130 is restrained in the accommodating cavity. In this way, the first noise reducer 120, the second noise reducer 130, and the smoke shield 110 are connected as one body. In this smoke damper assembly 100, the accommodating cavity is equivalent to the space formed by the recess of the enclosure portion 122. The smoke damper 110 only serves to block the opening 1211, making the form of the smoke damper 110 more similar to that of a conventional smoke damper. The connection portion 121 is threadedly connected to the smoke damper 110, making the connection between the first noise damper 120 and the smoke damper 110 easier to disassemble. The connection between the first noise damper 120 and the smoke damper 110 is also simpler. This makes the first noise damper 120 easier to assemble and disassemble, thereby simplifying the assembly and disassembly of the second noise damper 130. The smoke damper assembly 100 as a whole is easier to install and disassemble, and cleaning, repair, or replacement of the first and second noise dampers 120 and 130 is also simpler.

[0034] For example, see Figure 5 、 Figure 6 、 Figure 7 and Figure 8The enclosed portion 122 may include an enclosed bottom plate 1221 and an enclosed side plate 1222. One end of the enclosed side plate 1222 may be connected to the periphery of the enclosed bottom plate 1221, and the other end may be connected to the connecting portion 121. The enclosed bottom plate 1221 may be spaced apart by the enclosed side plate 1222 and the connecting portion 121. The enclosed bottom plate 1221 may be provided with a plurality of sound-absorbing holes 1223, and the accommodating cavity may be connected to the outside through the plurality of sound-absorbing holes 1223. The enclosed bottom plate 1221 and the enclosed side plate 1222 may be integrally formed, or they may be separately processed and then connected together by various means such as welding, clamping, or threaded connection. The enclosed side plate 1222 may be connected to the connecting portion 121 by various suitable means such as welding or threaded connection. It is understood that the enclosed side plate 1222 may be connected to the periphery of the opening 1211 to achieve the connection of the enclosed portion 122 to the periphery of the opening 1211. A plurality of sound-absorbing holes 1223 are provided on the enclosed bottom plate 1221, and sound waves can enter the accommodating cavity through the plurality of sound-absorbing holes 1223, so that the second noise reduction component 130 in the accommodating cavity can achieve a better noise reduction effect; and the plurality of sound-absorbing holes 1223 can realize small-hole sound absorption, so that the first noise reduction component 120 and the second noise reduction component 130 as a whole can achieve a better noise reduction effect.

[0035] Exemplarily, the enclosed side panel 1222 may include a first connecting panel 1222a and a second connecting panel 1222b. The first connecting panel 1222a may be attached to the connecting portion 121 and may be arranged around the opening 1211. The second connecting panel 1222b may be connected between the enclosed bottom panel 1221 and the first connecting panel 1222a. The first connecting panel 1222a being attached to the connecting portion 121 means that the first connecting panel 1222a may be parallel to the connecting portion 121. The contact area at the connection between the enclosed portion 122 and the connecting portion 121 is the contact area of the first connecting panel 1222a attached to the connecting portion 121. When the enclosed side panel 1222 is connected around the opening 1211, the contact area at the connection between the enclosed portion 122 and the connecting portion 121 may be larger, thereby making the connection between the enclosed portion 122 and the connecting portion 121 more stable, and thus improving the stability of the overall device.

[0036] See also Figure 4The handpiece 11 provided by the present invention may include a handpiece body 200 and a smoke shield assembly 100. The handpiece body 200 and the smoke shield 110 may enclose a smoke collection chamber, and the first noise reduction member 120 and the second noise reduction member 130 may be positioned within the smoke collection chamber. The smoke shield 110 may rotate relative to the handpiece body 200 between an open position and a closed position. For example, when the handpiece 11 is applied to an integrated stove, the smoke extraction from the integrated stove often produces a loud noise. Since the smoke extracted by the integrated stove can pass through the smoke collection chamber, the first and second noise reduction members 120, 130 may achieve a better overall noise reduction effect. Since the first and second noise reduction members 120, 130, and the smoke shield 110 may be integrally connected, the first and second noise reduction members 120, 130, 130 may rotate synchronously with the rotation of the smoke shield 110. When the smoke shield 110 is rotated to the closed position relative to the main body 200 of the handpiece, the first noise reducer 120 and the second noise reducer 130 can be located in the smoke collection chamber; when the smoke shield 110 is rotated to the open position relative to the main body 200 of the handpiece, the first noise reducer 120 and the second noise reducer 130 can be exposed outside the handpiece 11. Since there is usually oil smoke residue in the smoke collection chamber, and it is very inconvenient to remove the first noise reducer 120 and the second noise reducer 130 in the smoke collection chamber, when such a handpiece 11 is disassembled, the smoke shield 110 can be rotated to the open position relative to the main body 200 of the handpiece, so that the removal of the first noise reducer 120 and the second noise reducer 130 exposed outside the handpiece 11 can be naturally simpler and more convenient.

[0037] In one embodiment of the present invention, see Figure 1 、 Figure 2 、 Figure 3 and Figure 4The first noise reduction component 120 may include a first magnet, a first magnetic component 210 may be provided in the smoke collection chamber, the first magnetic component 210 may be connected to the head body 200, and when the smoke baffle 110 is in a closed position relative to the head body 200, the first magnetic component 210 and the first magnet may form a magnetic fit. The first magnetic component 210 may be provided at any suitable position on the head body 200 and extend into the smoke collection chamber. The first magnet may be a magnetic component provided on the first noise reduction component 120, or the first noise reduction component 120 may include a portion made of a magnetic material. For example, the first noise reduction component 120 may include a portion made of a metal material. This magnetic portion may form a magnetic fit with the first magnetic component 210, and the magnetic force may enable the smoke baffle 110 to be stably maintained in a closed position relative to the head body 200. To remove the first and second noise reduction members 120, 130, an external force can be applied to rotate the smoke shield 110 relative to the handpiece body 200 to an open position. The applied external force can be greater than the magnetic attraction between the first magnetic member 210 and the first magnet. While the smoke shield 110 is in the open position relative to the handpiece body 200, the first and second noise reduction members 120, 130 can be removed and installed. After these operations are complete, the smoke shield 110 can be rotated relative to the handpiece body 200 to a closed position. The first magnet and the first magnetic member 210 will form a magnetic attraction, maintaining the smoke shield 110 in the closed position relative to the handpiece body 200. In this manner, the smoke shield 110 can remain in the closed position relative to the handpiece body 200 when no external force is applied. Among them, after the smoke shield 110 is rotated to the closed position relative to the head body 200, the first magnet and the first magnetic attraction part 210 can automatically form a magnetic fit. When the smoke shield 110 needs to be rotated to the open position relative to the head body 200, the external force required does not need to be very large. Therefore, the overall device can be more convenient to disassemble, install and use.

[0038] For example, the first noise reduction member 120 may include a connecting portion 121 and an enclosing portion 122. The connecting portion 121 may have an opening 1211. The enclosing portion 122 may be connected around the opening 1211. The enclosing portion 122 may be recessed in a direction away from the smoke damper 110. The connecting portion 121 may be threadedly connected to the smoke damper 110, and the smoke damper 110 may block the opening 1211 and form a receiving cavity between the enclosing portion 122. A first magnet may be disposed on the connecting portion 121. The first magnet may be a magnetic member disposed on the connecting portion 121, or the connecting portion 121 may include a portion made of a magnetic material. For example, the connecting portion 121 may include a portion made of a metal material, and this magnetic portion may form a magnetically attractive fit with the first magnetic member 210. The first magnet is disposed on the connecting portion 121, and the smoke damper 110 may still be similar to a conventional smoke damper, so that the production and processing of the overall device can be simpler and more convenient. Furthermore, the connecting portion 121 may include a portion made of a magnetic material, and the portion made of a magnetic material on the connecting portion 121 may form a first magnet, so that the structure of the entire device may be simpler and easier to implement.

[0039] Exemplarily, the enclosed portion 122 may include an enclosed bottom plate 1221 and an enclosed side plate 1222. The enclosed side plate 1222 may be connected to the periphery of the enclosed bottom plate 1221. The enclosed bottom plate 1221 may be connected to the periphery of the opening 1211 through the enclosed side plate 1222. A plurality of sound-absorbing holes 1223 may be provided on the enclosed bottom plate 1221. The accommodating cavity may be connected to the smoke collecting cavity through the plurality of sound-absorbing holes 1223. Typically, when oil smoke passes through the smoke collection chamber, a loud noise is generated. The accommodating chamber is connected to the smoke collection chamber via multiple sound-absorbing holes 1223. The sound waves generated by the oil smoke passing through the smoke collection chamber can then enter the accommodating chamber through the multiple sound-absorbing holes 1223. This allows the second noise reduction member in the accommodating chamber to achieve a better noise reduction effect. Furthermore, the multiple sound-absorbing holes 1223 can achieve small-hole sound absorption. The first noise reduction member 120 is located in the smoke collection chamber, so the multiple sound-absorbing holes 1223 in the smoke collection chamber can achieve a better noise reduction effect through small-hole sound absorption. Thus, the first noise reduction member 120 and the second noise reduction member 130 as a whole can achieve a better noise reduction effect.

[0040] In one embodiment of the present invention, see Figure 3 and Figure 4 The main body 200 of the machine head may be provided with a positioning pin 220 extending into the smoke collecting chamber, and the first noise reduction member 120 and / or the smoke baffle 110 may be provided with a hook 123. When the smoke baffle 110 is in the open position relative to the main body 200 of the machine head, the hook 123 may be hooked on the positioning pin 220. The forms of the positioning pin 220 and the hook 123 may match, for example, Figure 3 and Figure 4In the embodiment shown, the positioning pin 220 can be cylindrical, and the hook 123 can be hook-shaped, and the hook 123 can be hooked on the cylindrical positioning pin 220. The positioning pin 220 and the hook 123 can be arranged in a coordinated manner, for example, Figure 3 and Figure 4 In the illustrated embodiment, the hook 123 can be perpendicular to the smoke deflector 110, allowing the locating pin 220 to be parallel to the smoke deflector 110. Of course, in other embodiments not shown, the locating pin 220 and the hook 123 can be of various other matching configurations, which are not limited herein. When the smoke deflector 110 is in the open position relative to the handpiece body 200, the hook 123 engages the locating pin 220, ensuring that the smoke deflector 110 does not fall off when in the open position relative to the handpiece body 200. This ensures that the smoke deflector 110 remains in the open position relative to the handpiece body 200 without applying external force. When the smoke deflector 110 is in the open position relative to the handpiece body 200 and the first and second noise reducers 120, 130 are removed, no external force is required to maintain the smoke deflector 110 in the open position relative to the handpiece body 200, thereby facilitating removal of the first and second noise reducers 120, 130.

[0041] In one embodiment of the present invention, a positioning pin 220 may be provided on the handpiece body 200, and a hook 123 may be provided on the first noise reduction member 120 and / or the smoke shield 110. A first magnetic member 210 may be provided on the handpiece body 200, and a first magnet may be provided on the first noise reduction member 120. When the smoke shield 110 is in the open position relative to the handpiece body 200, the hook 123 may engage the positioning pin 220, thereby maintaining the smoke shield 110 in the open position relative to the handpiece body 200 without applying any external force. When the smoke shield 110 is in the closed position relative to the handpiece body 200, the first magnet and the first magnetic member 210 may form a magnetic attraction, thereby maintaining the smoke shield 110 in the closed position relative to the handpiece body 200 without applying any external force. When the smoke shield 110 rotates between the open and closed positions relative to the handpiece body 200, an external force naturally acts on the smoke shield 110. Therefore, the smoke shield 110 can remain stable when it is in the open position or the closed position relative to the head body 200. Such a smoke shield 110 does not need to be rotated to be connected to the head body 200, that is, the smoke shield assembly 100 can be set independently of the head body 200. The overall structure of such a head 11 can be simpler and the cost can be lower.

[0042] For example, a second magnetic member (not shown in the figure) may be provided on the handpiece body 200, and a second magnet (not shown in the figure) may be provided on the smoke damper 110. When the smoke damper 110 is in the closed position relative to the handpiece body 200, the second magnetic member can form a magnetic fit with the second magnet. The second magnetic member can be provided at any suitable position on the handpiece body 200. The second magnet can be a magnetic member provided on the smoke damper 110, or it can be a portion of the smoke damper 110 made of a magnetic material. For example, the smoke damper 110 can include a portion made of a metal material, and this magnetic portion can form a magnetic fit with the second magnetic member. The magnetic force can stably maintain the smoke damper 110 in the closed position relative to the handpiece body 200. When it is necessary to remove the first noise reduction member 120 and the second noise reduction member 130, an external force can be applied to rotate the smoke damper 110 to the open position relative to the handpiece body 200. At this time, the external force applied can be greater than the magnetic force between the second magnetic member and the second magnet. When the smoke shield 110 is in the open position relative to the handpiece body 200, the first noise reduction member 120 and the second noise reduction member 130 can be removed and installed. After these operations are completed, the smoke shield 110 can be rotated relative to the handpiece body 200 to the closed position. The second magnet and the second magnetic member will then form a magnetic engagement, maintaining the smoke shield 110 in the closed position relative to the handpiece body 200. In this manner, the smoke shield 110 can remain in the closed position relative to the handpiece body 200 when no external force is applied. After the smoke shield 110 is rotated to the closed position relative to the handpiece body 200, the second magnet and the second magnetic member automatically form a magnetic engagement. When the smoke shield 110 is rotated to the open position relative to the handpiece body 200, a low external force is required. This makes the overall device more convenient to remove, install, and use.

[0043] In one embodiment of the present invention, see Figure 1 、 Figure 2 、 Figure 3 and Figure 4A smoke inlet 300 may be provided between the head body 200 and the smoke baffle 110 and above the smoke baffle 110, and the smoke collecting chamber may be connected to the outside through the smoke inlet 300. Taking the application of the head 11 to an integrated stove as an example, when the integrated stove extracts oil smoke, external oil smoke may enter the smoke collecting chamber through the smoke inlet 300, and enter the fuselage 12 through the smoke collecting chamber. The head 11 may usually be connected to the top of the fuselage 12. The smoke inlet 300 may be higher than the first noise reduction member 120 and the second noise reduction member 130. In this way, the oil smoke entering the smoke collecting chamber from the smoke inlet 300 will pass through the first noise reduction member 120 and the second noise reduction member 130, so that all the oil smoke entering the smoke collecting chamber will pass through the first noise reduction member 120 and the second noise reduction member 130. The first noise reduction member 120 and the second noise reduction member 130 can reduce the noise of all the oil smoke entering the smoke collecting chamber, which can also make the noise reduction effect of the entire device better and the noise generated smaller.
