Description

Technical Field

[0001] This utility model relates to the field of smokers, and in particular to a smoker. Background Technology

[0002] A smoker is a tool used to add smoky aromas and flavors to food or beverages. Injecting smoke into food or beverages not only adds a smoky dimension to the taste but also brings a psychedelic aesthetic to the eyes.

[0003] Existing electric smokers typically consist of two detachable, electrically connected parts. The upper part houses an ignition device (electric arc), while the lower part contains a combustion chamber and a flue. Activating the ignition device ignites the smoking material, and the resulting smoke enters the cup through the smoke channel. During use, the smoking fuel is placed in the combustion chamber, the upper and lower parts are closed, and the ignition device is activated to automatically ignite the smoking material. After a few seconds, the smoking material begins to burn, and the smoke enters the cup through the smoke outlet. However, in existing electric smokers, a smoke outlet is located at the bottom of the combustion chamber, with a flue connecting the smoke outlet and the smoke outlet. In this structure, ash and small particles produced by the combustion of smoking fuel in the combustion chamber enter the flue through the smoke outlet and then fall into the cup through the smoke outlet, affecting the user's drinking experience.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a smoker whose combustion chamber is used to hold the fuel to be burned and to transport smoke upwards. After the fuel burns, the ash remains in the combustion chamber. With the inlet of the flue located above the combustion chamber, the smoke generated after the fuel burns can enter the flue upwards and then be transported through the flue to the smoke outlet located at the lower end of the shell. This allows the smoke generated after combustion to enter the cup when the smoker is placed on the cup, while preventing the ash and small particles generated after combustion from falling directly into the cup, thus improving the user experience of the smoker.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smoker, comprising:

[0008] The housing has an air inlet and a smoke outlet at its lower end.

[0009] A combustion chamber, disposed within the housing, is used to hold fuel to be burned and to convey smoke upwards;

[0010] An ignition device is provided corresponding to the combustion chamber and is used to ignite the fuel to produce smoke.

[0011] A switching device, which is electrically connected to the ignition device, is used to trigger the ignition device to ignite;

[0012] The flue is disposed within the housing. The inlet of the flue is located above the combustion chamber and is used to receive the smoke generated by the combustion of fuel in the combustion chamber. The outlet of the flue is connected to the smoke outlet and is used to deliver smoke to the smoke outlet.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0014] The combustion chamber is used to hold the fuel to be burned and to convey smoke upwards. After the fuel burns, the ash remains in the combustion chamber. In conjunction with the inlet of the flue located above the combustion chamber, the smoke generated after the fuel burns can enter the flue upwards and then be conveyed through the flue to the outlet located at the lower end of the casing. This allows the smoke generated after combustion to enter the cup when the smoker is placed on the cup, while preventing the ash and small particles generated after combustion from falling directly into the cup, thus improving the user experience of the smoker.

[0085] First, it should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0086] Example 1:

[0087] Please refer to Figures 1 to 15 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a housing 10, a combustion chamber 20, an ignition device 30, a switching device 40, and a flue 50.

[0088] The housing 10 is provided with an air inlet 101 and a smoke outlet 102 at its lower end. The combustion chamber 20 is disposed inside the housing 10 and is used to hold fuel to be burned and to convey smoke upwards. The ignition device 30 is disposed corresponding to the combustion chamber 20 and is used to ignite the fuel to generate smoke. The switch device 40 is electrically connected to the ignition device 30 and is used to trigger the ignition device 30 to ignite. The flue 50 is disposed inside the housing 10, with its inlet 501 located above the combustion chamber 20 and used to receive the smoke generated by the combustion of fuel in the combustion chamber 20. The outlet 502 of the flue 50 is connected to the smoke outlet 102 and is used to convey smoke to the smoke outlet 102.

[0089] See Figures 4 to 6 As shown, the housing 10 includes an upper housing 11 and a lower housing 12 connected to the bottom of the upper housing 11. The bottom of the upper housing 11 is provided with a second positioning post 111. Correspondingly, the lower housing 12 is provided with a third mounting post 121 that matches the second positioning post 111. The third mounting post 121 is fixedly connected to the second positioning post 111 by a third screw 122. The ignition device 30 and the flue 50 are both fixed on the lower housing 12.

[0090] See Figure 7 , Figure 8 and Figure 14 As shown, the flue 50 includes a first channel 503, a second channel 504 and a third channel 505. The first channel 503 is connected to the combustion chamber 20 and extends laterally. The second channel 504 is connected to the first channel 503 and extends downward. The third channel 505 is connected to the second channel 504 and extends laterally, and is connected to the smoke outlet 102. The smoke outlet 102 is located at the lower center of the housing 10.

[0091] Specifically, a metal baffle 60 is provided at the top of the inner wall of the first channel 503 to protect the inner top wall of the first channel 504. The inner top wall of the second channel 504 and the metal baffle 60 together have a first ventilation opening 601. The first ventilation opening 601 accelerates fuel combustion in the combustion chamber 20, allowing for rapid and large-scale smoke production. A conical protrusion 602 is provided at the bottom of the metal baffle 60 corresponding to the combustion chamber 20. A fan 70 is provided in the third channel 505, located below the second channel 504, and above the second channel 504 corresponding to the fan 70. The device includes an oil storage device 80, which comprises a smoke channel 81 and an oil storage tank 82 disposed on the outer periphery of the smoke channel 81. The outer periphery of the smoke channel 81 has an oil guiding slope 83 extending downward and outward. The oil guiding slope 83 makes it easier for the e-liquid to come into contact with the oil storage device 80 and be stored in the oil storage tank 80. The contact area is larger than that of the vertical outer wall surface. The top of the smoke channel 81 is higher than the top of the oil storage tank 80, which makes the oil storage capacity of the oil storage tank 80 larger. The e-liquid in the oil storage tank 80 will not flow into the smoke channel 81. A filter screen 90 is disposed between the oil storage device 80 and the fan 70.

[0092] The flue 50 is fixed to the lower shell 12 with screws. The flue 50 includes a left shell 51 and a right shell 52 that are interlocked. A support protrusion 506 is provided between the left shell 51 and the right shell 52 for installing a metal baffle 60, an oil storage device 80, and a filter screen 90. The support protrusion 506 limits the vertical position and, together with the left shell 51 and the right shell 52, fixes the metal baffle 60, the oil storage device 80, and the filter screen 90 in the flue 50. The oil storage device 80 is detachably installed in the flue 50. After the oil storage device 80 is full of e-liquid, it can be removed for direct cleaning. Alternatively, oil-absorbing paper can be placed in the oil storage tank 80. When it is necessary to empty the e-liquid from the oil storage tank 80, only the oil-absorbing paper needs to be replaced, which is more convenient and faster. (See reference) Figure 5 As shown, the lower shell 12 is provided with a third positioning post 123, and the fan 70 is locked in the third positioning post 123 through the positioning hole 71;

[0093] Preferred options, please refer to Figure 4 and Figure 5 As shown, an annular boss 107 is provided on the outer periphery of the top of the smoke outlet 102 inside the housing 10, and the annular boss 107 extends into the flue 50.

[0094] In this embodiment, the flue 50 is made of plastic. The metal baffle 60 prevents the flue 50 from burning and melting due to heat, thus protecting it. Simultaneously, small particles generated by fuel combustion are adsorbed onto the metal baffle 60, preventing them from entering the fan 70. The conical protrusion 602 has a concave-convex structure. The conical protrusion 602's upper surface is positioned away from the inner top wall of the first channel 504, preventing direct contact between the heat source and the flue 50, thereby protecting it. Furthermore, the lower surface of the conical protrusion 602 further increases the adsorption area, making... The lower surface of the conical protrusion 602 can adsorb more small particles produced by fuel combustion, and the two sides of the metal baffle 60 can also be extended downward to provide side plates, thereby more comprehensively protecting the flue 50; the oil storage device 80 is made of metal, which can prevent smoke oil from corroding the fan 70 and can also play a cooling role, preventing the high temperature from burning the fan 70. In conjunction with the setting of the annular protrusion 107, it can further play a role in blocking smoke oil and preventing smoke oil from flowing out of the smoke outlet 102. The structure is cleverly designed; and the filter screen 90 can further purify the smoke passing through the fan 70.

[0095] See Figure 1 and Figure 2 As shown, the lower end of the housing 10 is provided with a plurality of support feet 103 for raising the smoke outlet 102. The smoke outlet 102 is located in the area surrounded by the plurality of support feet 103. When the smoker is placed on a flat surface, the support feet 103 keep the smoke outlet 102 away from the flat surface, so as to avoid contaminating the smoke outlet 102 and thus contaminating the beverages such as alcohol in the cup body 100.

[0096] See Figure 3 , Figure 5 , Figure 6 and Figure 9 As shown, the combustion chamber 20 is disposed on a pull-out member 110, which is removably disposed in the housing 10. The housing 10 has an opening 104 for the pull-out member 110 to extend into and be pulled out.

[0097] Specifically, the bottom of the inlet 501 of the flue 50 is provided with a baffle 507 and a guide plate 508. The lower shell 12 is provided with a left baffle 124 and a right baffle 125. The left baffle 124, the right baffle 125, the baffle 507, and the guide plate 508 together constitute the pull-out groove 105. The pull-out component 110 is pull-outly disposed in the pull-out groove 105. Between the left baffle 124 and the right baffle 125, at the bottom of the pull-out groove 105, a plurality of lower support bars 126 are provided. The plurality of lower support bars 126 form a lower support platform. The upper shell 11 is provided with a plurality of upper support bars 112 at the top of the pull-out groove 105 corresponding to the lower support platform. The plurality of upper support bars 112 form an upper support platform.

[0098] The pull-out component 110 includes an extension rod 1101, a combustion chamber mounting position 1102 disposed at one end of the extension rod 1101, and a handle portion 1103 disposed at the other end of the extension rod 1101. The end of the combustion chamber mounting position 1102 away from the extension rod 1101 is offset from the central axis 108 of the housing 10 and is located on the side of the central axis 108 away from the extension rod 1101, so that the combustion chamber mounting position 1102 is eccentrically arranged relative to the central axis 108 of the housing 10. The combustion chamber mounting position 1102 is hollow. The combustion chamber 20 includes a combustion chamber 21 and a connecting portion 22. The combustion chamber 21 is exposed in the combustion chamber mounting position 1102, and the connecting portion 22 is fixedly connected. The pull-out piece 110 on the extension rod 1101 eliminates the need to open the upper shell 11 before adding fuel. Instead, the pull-out piece 110 is simply pulled out, fuel is loaded into the combustion chamber 21, and then the pull-out piece 110 is pushed into the pull-out slot 105. This makes fuel addition and pouring more convenient. Furthermore, the eccentric arrangement of the combustion chamber mounting position 1102 extends the length of the extension rod 1101, providing ample space for the user to grip and preventing accidental contact with the area near the combustion chamber mounting position. This also prevents burns and makes it easier for the user to grasp the rod. Additionally, the structure of the pull-out piece 110 functions like a scoop, allowing for direct scooping and adding of fuel, eliminating the need for filling tools and further improving operational convenience.

[0099] Preferably, the flue 50 extends towards the opening with an extension plate 509. The extension plate 509 is provided to prevent fuel from entering the housing 10 when the entire smoke generator is inverted. The bottom of the upper support platform is covered with a baffle plate 113. The baffle plate 113 is also provided to prevent fuel from entering the compartment formed between the upper support bars 112. The lower support platform, the baffle plate 113, and the extension plate 509 limit the vertical movement of the pull-out member 110. The bottom of the combustion chamber 21 has an air inlet 211 for accelerating fuel combustion, and the lower end of the housing 10 is opened corresponding to the air inlet 211. A second vent 106 is provided, which facilitates air intake into the combustion chamber 21. Simultaneously, since the lower shell 12 forms a sealed space inside the cup body 100 when it is attached to the top, the fan 70 can drive some of the air from the cup body 100 through the second vent 106 and air inlet 211 into the flue 50, allowing the smoke generated by the burning fuel to enter the cup body 100 more smoothly. A heat insulation plate 23 is provided at the bottom of the combustion chamber 20, which prevents damage to the shell 10 and its internal components during combustion.

[0100] In this embodiment, a latch 1104 is provided at the front end of the combustion chamber mounting position 1102, and correspondingly, a notch 212 is provided at the front end of the combustion chamber 21. The latch 1104 is fastened to the notch 212 to prevent the front end of the combustion chamber 20 from detaching from the pull-out member 110. An anti-detachment structure is provided between the pull-out member 110 and the housing 10 to limit the pull-out member 110 from detaching from the housing 10. The anti-detachment structure includes a first magnetic element (not shown in the figure) and a second magnetic element (not shown in the figure). The first magnetic element is provided on the extension rod 1101, and the second magnetic element is correspondingly provided inside the housing 10, thereby ensuring the stability of the pull-out member 110. When placed at an angle, the entire pull-out member 110 will not slide out.

[0101] See Figure 5 and Figure 10 As shown, the ignition device 30 includes a heating wire 31 and a heating control plate 32. The heating wire 31 is disposed on the inner bottom surface of the combustion chamber 21. The two ends of the heating wire 31 are connected to conductive contacts 33. The conductive contacts 33 pass downward through the combustion chamber 21 and are exposed at the bottom of the combustion chamber 21. The heating control plate 32 is electrically connected to two conductive springs 321. An elastic element 34 is disposed between the bottom of the conductive springs 321 and the housing 10. The elastic force of the elastic element 34 drives the conductive springs 321 to abut against the conductive contacts 33. The combustion chamber 20 is made of ceramic material. The ceramic combustion chamber 20 has the characteristics of being non-conductive, high temperature resistant, and high thermal efficiency, and can play a good heat insulation role to prevent the extension rod 1101 near the combustion chamber 20 from getting too hot.

[0102] Specifically, the conductive contact 33 is connected to a connecting rod 331. The conductive contact 33 is located at the bottom of the combustion chamber 21, and the connecting rod 331 is located in the combustion chamber 21 and connected to a heating wire 31. The heating wire 31 is located on the inner bottom surface of the combustion chamber 21. In this structure, when fuel is filled into the combustion chamber 21, the area around the heating wire 31 is surrounded by fuel. Ignition from below allows the fuel to burn from bottom to top, resulting in more complete contact with the fuel and faster smoke generation. Combined with the setting of the air inlet 211, the fuel combustion can quickly generate a large amount of smoke.

[0103] In some other embodiments, multiple smoke outlets are provided at the bottom of the ceramic combustion chamber. The flue connects the smoke outlets of the combustion chamber and the smoke outlet of the shell. The smoke generated after the fuel in the combustion chamber is burned flows out from the smoke outlets through the flue and then out from the smoke outlet. The combustion chamber is mounted on a pull-out component, so that the combustion chamber can be pulled out of the shell. The pull-out structure combined with the ceramic combustion chamber can prevent burns and enable quick fuel replacement.

[0104] See Figure 2 , Figures 11 to 13As shown, a rotating component 120 for setting the smoking time is provided at the upper middle part of the housing 10. The rotating component 120 includes a rotating shell 1201 and a circuit board 1202 disposed in the rotating shell 1201. The switching device 40 is electrically connected to the circuit board 1202. A plurality of air inlets 101 are provided, and the plurality of air inlets 101 are arranged around the outer periphery of the rotating component 120.

[0105] Specifically, the bottom of the rotating shell 1201 is provided with an annular portion 12011, the outer peripheral wall of the annular portion 12011 is provided with external teeth 12012, and the inner peripheral wall of the annular portion 12011 is provided with internal teeth 12013. The upper end of the shell 10 (specifically the upper end of the upper shell 11) is recessed downward with a first groove 114, and the bottom wall of the first groove 114 is recessed downward with a second groove 115. The first groove 114 and the second groove 115 form an annular step 116, and the top of the annular step 116 is provided with a surface for contact with the shell 10. The bottom abuts against the elastic protrusion 117. The setting of the elastic protrusion 117 can reduce the gap between the housing 10 and the rotating housing 1201, and prevent the rotating housing 1201 from shaking and producing abnormal noise. The inner circumference of the annular step 116 is provided with an elastic locking protrusion 118 that can selectively engage the outer tooth 12012. The outer tooth 12012 and the elastic locking protrusion 118 cooperate. The elastic locking protrusion 118 includes a locking member that holds the outer tooth 12012 and a spring that drives the locking member to abut against the outer tooth 12012, so that the rotating housing 1201 generates a rotating click-like feel and sound when rotating.

[0106] The bottom wall of the second groove 115 is recessed downward to form a third groove 119. A gear 1203 that meshes with the internal gear 12013 is provided in the third groove 119. An encoder 1204 that cooperates with the gear 1203 is electrically connected to the circuit board 1202. The encoder 1204 allows the rotating shell 1201 to adjust the smoking time. By rotating the rotating shell 1201 a certain number of times, the desired smoking time can be selected.

[0107] The top of the rotating shell 1201 has a downward-facing receiving groove 1205. The bottom of the receiving groove 1205 is connected to the area enclosed by the annular portion 12011. A support frame 1206 is provided in the receiving groove 1205. A first mounting post 1151 is provided near the internal tooth 12013 in the second groove 115. The first mounting post 1151 is locked with a first screw 1152. The top of the first screw 1152 has a first nut 1153. The vertical movement of the rotating shell 1201 is restricted between the first nut 1153 and the top of the shell 10. When the first screw 1152 is locked with the first mounting post 1151, the first nut 1153 limits the internal tooth 12013, preventing the rotating shell 1201 from detaching upwards, while not hindering the rotation of the internal tooth 12013 and the gear 1203. The circuit board 1202 is fixed to the bottom of the support frame 1206.

[0108] Furthermore, a first positioning post 12061 is provided at the bottom of the support frame 1206, and correspondingly, a second mounting post 1154 is provided in the second groove 115. The first positioning post 12061 is inserted into the second mounting post 1154, and a second screw 1155 passes through the second mounting post 1154. The top of the second screw 1155 is fixed to the first positioning post 12061, and the bottom of the second screw 1155 has a second nut 1156 to prevent the support frame 1206 from falling out. The switching device 40 is located at the bottom of the circuit board 1202. An elastic pad 130 is provided on the second groove 115 corresponding to the switch device 40. The support frame 1206 can move downward to trigger the switch device 40. The second nut 1156 limits the support frame 1206 from moving upward, but the support frame 1206 can move downward a certain distance. The switch device 40 is a trigger switch. Due to the setting of the elastic pad 130, this distance is supported by the elastic pad 130. When the support frame 1206 is pressed down, the elastic pad 130 first deforms to a certain extent before the trigger switch is activated. The elastic pad 130 is a sponge pad, which increases the distance and prevents accidental activation.

Specifically, the support frame 1206 has multiple exposed slots 12062 around its perimeter, and the rotation count indicator 12021 corresponds to one of these slots. Multiple rotation indicator lights 12021 are provided in the 12062, and the number of exposed slots 12062 is lit in different colors according to the number of rotations. Within the area enclosed by the multiple exposed slots 12062, there are also power indicator light holes 12063, timer display holes 12064, and charging symbol holes 12065. Power indicator lights 12022, timer displays 12023, and charging status indicator lights 12024 are respectively provided. The timer display 12023 counts down. The cover plate 1207 is also provided with a press indicator mark 12071 for the switch device 40 to indicate to the user to press to start.

[0110] The circuit board 1202 is electrically connected to the heating control board 32 via wires passing through the upper shell 11.

[0111] When using it, please refer to Figure 15 As shown, the housing 10 can be placed directly on the cup body 100, and smoke can be delivered directly through the smoke outlet 102. Alternatively, a hose (not shown in the figure) can be connected to the smoke outlet 102 through a connector (not shown in the figure) to deliver smoke through the hose. A sealing ring is set at the end of the connector that is inserted into the smoke outlet 102. The sealing ring can prevent smoke leakage and ensure that the smoke enters the hose after entering the connector from the smoke outlet 102.

[0112] Example 2:

[0113] See Figure 16 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is substantially the same as that of embodiment one, except that:

[0114] In this embodiment, the flue 50 includes a first channel 503 and a second channel 504. The first channel 503 is connected to the combustion chamber 20 and extends laterally. The second channel 504 is connected to the first channel 503 and extends downward, and is connected to the smoke outlet 102. A fan 70 is provided at the bottom of the second channel 504. Smoke enters the first flue 50 from the combustion chamber 20 and then enters the second flue 50. Under the action of the fan 70, it flows out from the smoke outlet 102. In this embodiment, the smoke outlet 102 is eccentrically positioned. In order to make the smoke outlet 102 located in the center, the pull-out member 110 can be shortened, so that the combustion chamber 21 is offset to the right. The length of the first flue 50 can be designed as needed so that the second channel 504 is located in the center.

[0115] Example 3:

[0116] See Figure 17 As shown, it illustrates the specific structure of a preferred embodiment three of the present invention, which is substantially the same as that of embodiment one, except that:

[0117] In this embodiment, the flue 50 includes an upper body 53 disposed on the upper shell 11 and a lower body 54 disposed on the lower shell 12. The first channel 503 is located on the upper body 53, and the second channel 504 is located on the lower body 54. After the upper shell 11 covers the lower shell 12, the first channel 503 and the second channel 504 are connected. In this structure, the upper body 53 can be integrally formed on the upper shell 11, and the lower body 54 can be integrally formed on the lower shell 12. The integral forming setting can eliminate the need for assembly of the flue 50, making the assembly of the entire smoker more convenient. The upper body 53 can also be screwed to the upper shell 11, and the lower body 54 can also be screwed to the lower shell 12, which facilitates the assembly of the internal parts of the flue 50.

[0118] The key design feature of this utility model is:

[0119] The combustion chamber is used to hold the fuel to be burned and to convey smoke upwards. After the fuel burns, the ash remains in the combustion chamber. In conjunction with the inlet of the flue located above the combustion chamber, the smoke generated after the fuel burns can enter the flue upwards and then be conveyed through the flue to the outlet located at the lower end of the casing. This allows the smoke generated after combustion to enter the cup when the smoker is placed on the cup, while preventing the ash and small particles generated after combustion from falling directly into the cup, thus improving the user experience of the smoker.

[0120] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
