Description

Technical Field

[0001] The invention relates to the technical field of stoves, in particular to an alcohol stove capable of evenly controlling fire. Background Art

[0002] An alcohol stove is a small stove that uses alcohol as fuel. It is often used for cooking simple meals or heating, such as in hot pot stoves and pot stoves. As a very convenient heating device, the alcohol stove can meet local heating needs. It can be used in laboratories or for heating food. As a very convenient heating device, the alcohol stove has a wide range of uses and can meet the needs of different heating environments. Existing alcohol stoves have the following problems when used: First, the flame-blocking plates are generally assembled into a scissor shape. When the two plates are separated, the space for the flame to pass through is unevenly distributed circumferentially. The closer to the scissor hinge, the smaller the space the flame can pass through. Therefore, different positions on the bottom of the pot receive different amounts of heat, resulting in uneven heating of the bottom of the pot.

[0003] Secondly, the pot legs are generally made of a serrated metal strip or plate, and the shape and size of the pot legs are fixed. If the shape and size of the pot body do not match the pot legs, then the pot legs will only contact the pot body at one point. When the food in the pot is unevenly distributed as it is eaten, it is very easy to cause the pot body to tilt.

[0004] The above problems all make the existing alcohol stove inconvenient to use. Based on this, the present application proposes an alcohol stove with uniform fire control. Summary of the Invention

[0017] 2. The present application provides an alcohol stove with uniform fire control. By evenly arranging the stove door paddles above the fuel hopper, when the adjustment handle is rotated, several stove door paddles are deflected synchronously, and the circumferential distribution of the gap space is relatively uniform. This can solve the problem of uneven distribution of the gaps formed by the existing scissor-type paddles, which leads to uneven distribution of the flame at the bottom of the food pot, thereby improving the uniformity of food heating.

[0018] 3. The present application provides an alcohol stove with uniform fire control. The pot feet are evenly arranged circumferentially on the top surface of the upper shell. When the diameter of the pot filled with food is large, the auxiliary pot rack is pulled out to match the pot body, and the vertical section of the auxiliary pot rack is used to clamp the pot body to prevent the pot body from tilting. The main support of the pot foot is rotated to tilt the main support of the pot foot to match the shape of the pot body, thereby increasing the contact friction between the main support of the pot foot and the pot body, thereby comprehensively improving the stability of the pot when placed on the main support of the pot foot.

The spaces between adjacent inner edges 301 form snap-on notches 302. During installation, the inner edges 301 are placed on the top surface of the lower shell 1 and rotated so that the inner edges 301 are rotated and inserted under the raised snaps 105, thereby securing the upper shell 3 to the top of the lower shell 1.

[0025] See attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 , Attachment Figure 5 As shown, a support shell 2 is installed inside the lower shell 1. The support shell 2 is in the shape of a truncated cone as a whole. The top of the support shell 2 is provided with a top edge 201 facing the inner periphery, and the top surface of the top edge 201 is evenly circumferentially provided with limiting holes 202. The bottom end of the support shell 2 is provided with a bottom edge 203 facing the outer periphery, and a limiting hole 204 is provided on the bottom edge 203. The bottom edge 203 is placed on the surface of the inner edge 102, and the limiting hole 204 is engaged with the limiting buckle 103. The side of the support shell 2 is also provided with a handle groove 104 corresponding to the lower shell 1.

[0026] See attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 , Attachment Figure 5 As shown, the support housing 2 is mounted with a fuel hopper 4. The fuel hopper 4 is a hollow cylinder. The top edge of the fuel hopper 4 is integrally formed with a pot top rim 401 facing the periphery. Positioning holes 402 are circumferentially defined on the surface of the pot top rim 401. The bottom edge of the pot top rim 401 is provided with a pot rim 403 facing the periphery. Second stoppers 404 are evenly distributed around the circumference of the pot rim 403. During installation, the pot rim 403 is placed on the top rim 201, and the second stoppers 404 engage with the second stopper holes 202.

[0027] See attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 , Attachment Figure 5 As shown, the top rotating cover of the fuel hopper 4 is provided with a furnace door gear ring 5, and the top surface of the furnace door gear ring 5 is evenly provided with adjustment buckles 501 in the circumferential direction, and the bottom edge of the furnace door gear ring 5 is evenly provided with gear teeth 502 toward the periphery. The furnace door gear ring 5 is sleeved on the edge 403 of the pot, and the top surface of the furnace door gear ring 5 after sleeved is flush with the surface of the pot top edge 401.

[0028] See attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6As shown, a furnace door paddle 6 is provided above the furnace door gear ring 5. The furnace door paddle 6 is generally fan-shaped with an arc-shaped edge. Several furnace door paddles 6 are arranged in a circle. The surface of the furnace door paddle 6 is provided with an adjustment groove 601 and a second positioning hole 602 near the outer edge. The second positioning hole 602 is located at one end of the adjustment groove 601. The furnace door paddle 6 is placed on the top surface of the furnace door gear ring 5 and the pot top rim 401. The second positioning hole 602 is aligned with the first positioning hole 402. Positioning buckles 7 are inserted into the second positioning hole 602 and the first positioning hole 402. The adjustment buckle 501 is sleeved in the adjustment groove 601. One end of the adjustment groove 601 is also provided with a large-diameter circular hole with a diameter greater than the width of the second positioning hole 602. The adjustment buckle 501 is inserted into the adjustment groove 601 through the large-diameter circular hole. After the furnace door paddle 6 is installed with the fuel hopper 4 and the furnace door gear ring 5, the center of the adjustment groove 601 and the center of the furnace door gear ring 5 have a certain angle, so that when the furnace door gear ring 5 rotates around its own center, the adjustment buckle 501 has a squeezing effect on the inner wall of the adjustment groove 601, thereby pushing the furnace door paddle 6 to deflect around the center of the second positioning hole 602 when the furnace door gear ring 5 rotates. Figure 6 As shown in FIG, the oven door paddle 6 is fully gathered. Figure 6 In the state shown in (a), when several door paddles 6 are deflected at the same time, the inner ends of the door paddles 6 gradually deflect outwards to form a certain gap space, as shown in the attached figure. Figure 6 In the state shown in (b), the fuel hopper 4, located below the oven door paddle 6, is exposed. Alcohol is placed in the fuel hopper 4. The greater the angle of the oven door paddle 6's deflection, the larger the gap created, allowing more space for the alcohol flame in the fuel hopper 4 to pass through. This increases the amount of heat the pot containing food above the pot legs 10 receives from the flame, accelerating the heating of the food. Therefore, adjusting the angle of the oven door paddle 6's deflection allows the flame size to be controlled.

[0029] See attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 7 As shown, the handle groove 104 on the side of the lower shell 1 and the supporting shell 2 is equipped with an adjusting handle 8, which drives the furnace door gear ring 5 to rotate. Figure 2 , Attachment Figure 3 , Attachment Figure 7As shown, the adjustment handle 8 includes a handle cover 801 and a handle housing 802. A gasket 803 is provided at the contact point between the handle housing 802 and the support housing 2. A symmetrical hook plate 811 is provided at the inner end of the handle cover 801. A hook groove 822 is provided on the outer periphery of the handle housing 802. The end of the hook plate 811 is snap-fitted into the hook groove 822. A sleeve 812 is provided in the middle of the inner end of the handle cover 801. A key shaft end cap 804 is sleeved on the end of the sleeve 812. The key shaft end cap 804 is in the form of two connected cylinders of different diameters. The smaller diameter cylinder is inserted into the inner cavity of the sleeve 812, and the larger diameter cylinder has a cylindrical cavity in the middle. A main key shaft 805 is inserted into the key shaft end cap 804. The main key shaft 805 is provided with a strip spline 851. A shaft sleeve 806 is sleeved on the outer periphery of the strip spline 851. A pin plate 852 is inserted into the main key shaft 805. A spline groove 861 is formed on the inner periphery of the shaft sleeve 806 to match the strip spline 851. The sleeve 806 and the strip spline 851 are sleeved together by the engagement of the strip spline 851 and the spline groove 861. The outer periphery of the shaft sleeve 806 is provided with a cross groove 862. The end of the handle housing 802 is provided with a cross protrusion 821. The cross protrusion 821 is snapped into the cross groove 862, realizing the linkage between the handle housing 802 and the shaft sleeve 806. When the handle housing 802 rotates, it can drive the shaft sleeve 806 to rotate. A furnace door adjustment ring gear 807 is sleeved onto the main key shaft 805. A cross-shaped keyway 871 is provided on the inner circumference of the furnace door adjustment ring gear 807. A pin plate 852 engages within the cross-shaped keyway 871, achieving linkage between the main key shaft 805 and the furnace door adjustment ring gear 807. Rotation of the main key shaft 805 drives the furnace door adjustment ring gear 807, which meshes with the gear teeth 502, thereby driving the furnace door ring gear 5 to rotate. A key shaft end sleeve 808 is sleeved onto the end of the furnace door adjustment ring gear 807.

[0030] See attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 , Attachment Figure 5As shown, a limiting buckle groove 205 is also provided on the top edge 201, and a limiting buckle three 405 is correspondingly provided on the pot edge 403. The limiting buckle three 405 is clamped in the limiting buckle groove 205. A through hole 206 is provided on the side of the supporting shell 2, and a limiting rod hole 303 is provided on the inner edge two 301. The limiting rod 9 is sleeved on the annular curling edge provided at the bottom of the limiting buckle groove 205, and the end of the limiting rod 9 away from the limiting buckle groove 205 passes through the through hole 206 and is inserted into the limiting rod hole 303. The limiting rod 9 comprises a three-bend rod and a ring buckle. The three-bend rod comprises a U-shaped bend section and a vertical bend section. The end of the U-shaped bend section is connected to the ring buckle, which is sleeved on the outer periphery of the bottom curled edge of the limiting buckle groove 205. A portion of the U-shaped bend section passes through the through hole 206, and the vertical bend section is connected to the end of the U-shaped bend section away from the ring buckle. The vertical bend section is inserted into the limiting rod hole 303. When the portion where the U-shaped bend section and the vertical bend section are connected is pressed downward, the bend of the U-shaped bend section deforms, allowing the vertical bend section to move downward out of the limiting rod hole 303. At this time, the upper shell 3 is released from the support shell 2. The upper shell 3 can be separated from the lower shell 1 by rotating the upper shell 3 in the opposite direction. On the contrary, when installing the upper shell 3, first rotate the upper shell 3 so that the inner edge 2 301 is engaged with the protruding buckle 105, and then insert the vertical bending section of the limiting rod 9 into the limiting rod hole 303 to achieve the limiting effect of the upper shell 3 and the lower shell 1 and the supporting shell 2, and prevent the upper shell 3 from rotating and separating from the lower shell 1 when an external force operation error occurs.

[0031] Directions: See attached Figure 1 As shown, the ends of the handle top cover 801 and the handle shell 802 are located outside the handle groove 104. Manually rotate the handle top cover 801 and the handle shell 802. The rotation of the handle shell 802 drives the shaft sleeve 806 to rotate, and the shaft sleeve 806 drives the main key shaft 805 to rotate. Since the pin plate 852 is engaged with the cross key groove 871, the main key shaft 805 drives the furnace door adjustment gear ring 807 to rotate. The furnace door adjustment gear ring 807 is engaged with the gear 502, so the furnace door adjustment gear ring 807 drives the furnace door gear ring 5 to rotate. The adjustment buckle 501 pushes the inner wall of the adjustment groove 601 as the furnace door gear ring 5 rotates, causing the furnace door paddle 6 to rotate around the center of the positioning hole 2 602. Referring to the figures of the present application, when the handle top cover 801 and the handle shell 802 rotate clockwise, it finally drives the furnace door gear ring 5 to rotate counterclockwise, and the furnace door paddle 6 presents the attached Figure 6 In the dispersed state shown in (b), when the handle top cover 801 and the handle housing 802 rotate counterclockwise, the oven door paddle 6 rotates clockwise and gathers. The fully gathered state is the attached state. Figure 6 As shown in (a), the function of adjusting the size of the gap space at the inner end of the furnace door paddle 6 is realized, thereby achieving the purpose of adjusting the size of the flame.

[0032] See attached Figure 1, Attachment Figure 2 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 8 As shown, the pot foot 10 includes a pot foot main support 111, an axis frame 113, an axis seat 115, and an axis cap 119. The top surface of the pot foot main support 111 is provided with an anti-slip protrusion, and the outer end top surface of the pot foot main support 111 is provided with a limiting tongue 112 facing the bottom of the pot foot main support 111. The two side edges of the pot foot main support 111 are bent inward to form a supporting edge, and an auxiliary pot frame 114 is slidably connected to the supporting edge. The auxiliary pot frame 114 is bent by a long U-shaped rod. The bottom end of the limiting tongue 112 is inserted into the middle of the U-shaped auxiliary pot rack 114 to prevent the auxiliary pot rack 114 from being completely pulled out from the supporting edge of the pot leg main support 111 and falling off; the auxiliary pot rack 114 moves along the supporting edge of the pot leg main support 111 to form a telescopic structure with the pot leg main support 111; the outer end bottom of the pot leg main support 111 is connected to the shaft rack 113, and the shaft rack 113 is sleeved on the outer periphery of the shaft seat 115. The middle part of 115 is provided with a through mounting hole, and the shaft seat 115 and the upper shell body 3 are integrally formed, which can save cost, or the shaft seat 115 can also be installed on the top surface of the upper shell body 3; a shaft ring sleeve 116 is sleeved in the mounting hole of the shaft seat 115, and a shaft rod 117 is horizontally penetrated inside the shaft ring sleeve 116. The inner end of the shaft cap 119 penetrates the shaft frame 113, the shaft seat 115 and one end of the shaft ring sleeve 116 are keyed, and the outer end of the shaft cap 119 is keyed to the shaft frame 113. There are two shaft caps 119, which are respectively connected to the shaft frame 113, the shaft seat 115, and the two ends of the shaft ring sleeve 116. The two ends of the shaft rod 117 extend to the outer ends of the two shaft caps 119; a torsion spring 118 is sleeved in the middle part of the shaft rod 117, and one end of the torsion spring 118 is squeezed on the groove wall of the semi-circular groove opened in the middle part of the shaft ring sleeve 116, and the other end of the torsion spring 118 is squeezed on the inner wall of the shaft seat 115.

[0033] There are at least three pot feet 10 and they are evenly distributed along the circumference of the upper shell 3. The pot filled with food is placed on the pot feet 10, and the plurality of pot feet 10 play a supporting role for the pot.

[0034] During use: a pot filled with food is placed on the pot leg main support 111. If the diameter of the pot is greater than the length of the pot leg main support 111, the auxiliary pot rack 114 is pulled outward, and the pot can be placed on the extension section of the pot leg main support 111 and the auxiliary pot rack 114. This allows the pot leg 10 of the present application to match pots of different diameters, expanding the scope of application of the alcohol stove of the present application. The auxiliary pot rack 114 and the pot leg main support 111 remain relatively stable through the friction between the two. At the same time, the vertical section of the auxiliary pot rack 114 located outside the pot leg main support 111 is used to squeeze and clamp the side wall of the pot body, thereby improving the stability of the pot and preventing the pot body from tilting due to uneven distribution of food in the pot during use. In addition, to match pot bodies of different shapes, the present application realizes the rotatable function of the pot leg main support 111 by connecting the shaft cap 119, the shaft rack 113, the shaft ring sleeve 116, and the shaft rod 117, and realizes the reset of the pot leg main support 111 by the torsion spring 118. For example, when the pot body has a circular bottom, the pot foot main support 111 rotates toward the center of the upper shell 3 with the shaft 117 as the central axis, so that the pot foot main support 111 tilts inward to match the circular pot bottom, increasing the contact area between the pot foot main support 111 and the pot body, and further improving the stability of the pot body on the pot foot main support 111. When the pot body leaves the pot foot main support 111, under the action of the torsion spring 118, the pot foot main support 111 rotates in the opposite direction to its horizontal initial state.
