Description

Technical Field

[0001] The present invention relates to the technical field of stoves, and particularly to a multi-functional alcohol stove with linkage adjustment. Background Art

[0002] An alcohol stove is a small cooking appliance fueled by alcohol, commonly used in simple meal cooking or heating processes, such as hot pot stoves, chafing dish stoves, etc. As a very convenient heating device, the alcohol stove can meet the need for local heating. It can be used in laboratories or during food heating. With a wide range of applications, the alcohol stove can adapt to the needs of different heating environments. However, the existing alcohol stoves have the following problems: Firstly, the pot feet are generally composed of a metal strip or plate with serrations. The shape and size of the pot feet are fixed. If the shape and size of the pot body do not match the pot feet, then only one point of the pot feet contacts the pot body. When the food in the pot body is unevenly distributed during consumption, it is extremely easy to cause the pot body to tilt.

[0003] Secondly, the volume of the fuel hopper for placing fuel in the existing alcohol stove is fixed, while the volumes of alcohol blocks vary. Large alcohol blocks cannot be put in, and small alcohol blocks have a flame too far from the bottom of the pot after being lit, resulting in a reduced heating effect on the bottom of the pot.

[0004] Thirdly, the plate for blocking the flame is generally assembled in a scissor shape. When adjusting, the blocking situation of the flame at different positions on the bottom of the pot by the plate is different, resulting in uneven heating of the bottom of the pot.

[0005] The above problems all lead to the inconvenient use of the existing alcohol stoves. Based on this, the present application proposes a multi-functional alcohol stove with linkage adjustment. Summary of the Invention

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0022] Please refer to Figure 1 , appendix Figure 2 As shown, a multifunctional alcohol stove with linkage adjustment includes a housing assembly. The housing assembly includes an upper housing 1 and a lower housing 2. The top surface of the upper housing 1 is circumferentially and evenly provided with pot leg assemblies 3. An oven door assembly 4 and a fuel hopper assembly 5 are arranged in the inner cavity of the lower housing 2. The oven door assembly 4 is located above the fuel hopper assembly 5. An adjusting handle assembly 6 is arranged on one side of the lower housing 2. The adjusting handle assembly 6 is linked with the oven door assembly 4 and the fuel hopper assembly 5.

[0023] Please refer to appendix Figure 1 , appendix Figure 2 , appendix Figure 5As shown in the figure, the furnace door assembly 4 includes a furnace door paddle 41, a furnace door seat ring 42, and a furnace door gear ring 43. An arc-shaped groove 411 and a positioning hole 412 are formed on the outer edge of the surface of the furnace door paddle 41. The furnace door paddle 41 is integrally in a fan-shaped structure with an arc-shaped edge, and the shape of the furnace door paddle 41 is similar to the cross-section of a water droplet; the furnace door seat ring 42 is integrally in a ring shape, and a positioning post 421 corresponding to the positioning hole 412 is provided on the top surface of the furnace door seat ring 42. A moving post 431 corresponding to the arc-shaped groove 411 is provided on the top surface of the furnace door gear ring 43. An annular tooth groove is provided on the outer periphery of the furnace door gear ring 43. The furnace door seat ring 42 is sleeved on the inner periphery of the furnace door gear ring 43. The moving post 431 is slidably sleeved in the arc-shaped groove 411, and the positioning post 421 is rotatably sleeved in the positioning hole 412. When the furnace door gear ring 43 rotates relative to the furnace door seat ring 42 with the furnace door seat ring 42 fixed, the rotation of the moving post 431 is restricted by the arc-shaped groove 411, causing the furnace door paddle 41 to rotate around the central axis of the positioning hole 412, thereby realizing the effect that several furnace door paddles 41 deflect outwards. Thus, a space is formed by the inner end gaps of several furnace door paddles 41 for the flame to pass through. Taking the state shown in the attached Figure 5 in (5b) as a reference, when the furnace door gear ring 43 rotates counterclockwise, several furnace door paddles 41 expand into the state shown in the attached Figure 5 in (5a); conversely, when the furnace door gear ring 43 rotates clockwise, several furnace door paddles 41 close. The fuel hopper assembly 5 is located below the furnace door assembly 4, and alcohol blocks are placed in the fuel hopper assembly 5. The space formed by the expansion of several furnace door paddles 41 is the space where the alcohol block flame shoots upwards. The larger this space is, the larger the flame is, and conversely, the smaller this space is, the smaller the flame is. Thus, the function of adjusting the flame size is achieved.

[0024] Refer to the attached figure 6 and the attached Figure 10 As shown, several column holes 422 and arc-shaped card slots 424 are also formed on the top surface of the furnace door seat ring 42. A ring hopper 423 is connected to the inner periphery of the furnace door seat ring 42.

[0025] Refer to the attached Figure 6, the fuel hopper assembly 5 includes a main hopper 51, a heat insulation plate 52, a guide frame 53 and a guide post 54. A number of guide frames 53 are evenly arranged in the circumferential direction of the heat insulation plate 52. The guide post 54 is slidably sleeved in a column groove integrally formed in the middle of the guide frame 53. The top end of the guide post 54 is connected in the column hole 422. The main hopper 51 covers the outer periphery of the annular hopper 423. The heat insulation plate 52 is placed on an ear plate integrally formed at the inner edge of a number of guide frames 53. The main hopper 51 is placed on the top surface of the heat insulation plate 52. A strip-shaped tooth groove 531 is provided at the outer edge of the guide frame 53. During use, with the furnace door seat ring 42 fixed, by driving the guide frame 53 to move up and down along the guide post 54, the heat insulation plate 52 and the main hopper 51 are driven to move up and down. The space enclosed by the main hopper 51 and the annular hopper 423 is used to place alcohol blocks. When the main hopper 51 moves upward, the space enclosed by the main hopper 51 and the annular hopper 423 decreases, and the volume of alcohol blocks that can be accommodated decreases; conversely, when the main hopper 51 moves downward, the space enclosed by the main hopper 51 and the annular hopper 423 increases, and the volume of alcohol blocks that can be accommodated increases. In practical applications, when the volume of the alcohol blocks is large, the main hopper 51 needs to be moved downward; conversely, when the volume of the alcohol blocks is small, the main hopper 51 is driven to move upward to facilitate placing alcohol blocks of different volumes. When the alcohol blocks are small, the main hopper 51 can be driven to move upward so that the distance between the flame of the burning alcohol blocks and the bottom of the pot is reduced, which is beneficial to the contact between the flame and the bottom of the pot and improves the heat receiving effect of the bottom of the pot.

[0026] Refer to the appendix Figure 1 , the appendix Figure 2 , the appendix Figure 10 As shown, the housing assembly further includes a bracket 7 and a foot pad 8. The bottom end of the lower housing 2 is integrally formed with furnace feet. Anti-slip foot pads 8 are provided at the bottom ends of the furnace feet. A bent ring plate is provided on the inner circumference of the lower housing 2 at the position of the furnace feet. Two bottom ear plates extending outward at the bottom end of the bracket 7 are connected to the bent ring plate at the furnace feet. An upper ear plate extending outward in the middle at the top end of the bracket 7 is inserted into an arc-shaped card slot 424 opened on the top surface of the furnace door seat ring 42. The adjustment handle assembly 6 is installed in the bracket 7. Thus, the overall support structure of the alcohol stove of this application is formed.

[0027] Refer to the appendix Figure 1 , the appendix Figure 2 , the appendix Figure 9As shown, the pot leg assembly 3 includes a main pot leg 31, a shaft bracket 32, a shaft seat 34, and a shaft cap 38. Anti-slip protrusions are provided on the top surface of the main pot leg 31. A limiting tongue 311 facing downward of the main pot leg 31 is provided on the top surface of the outer end of the main pot leg 31. The two side edges of the main pot leg 31 are bent inward to form a supporting edge. An auxiliary pot rack 33 is slidably connected to the supporting edge. The auxiliary pot rack 33 is bent into an L shape from a rectangular ring-shaped long rod. The bottom end of the limiting tongue 311 is inserted into the middle of the rectangular ring shape of the auxiliary pot rack 33 to prevent the auxiliary pot rack 33 from being completely pulled out of the main pot leg 31 and falling off; the auxiliary pot rack 33 moves along the supporting edge of the main pot leg 31 to form a telescopic structure with the main pot leg 31; the bottom of the outer end of the main pot leg 31 is connected to the shaft bracket 32. The shaft bracket 32 is sleeved on the outer periphery of the shaft seat 34. A through mounting hole is provided in the middle of the shaft seat 34. The shaft seat 34 is integrally formed with the upper housing 1, which can save costs, or the shaft seat 34 can also be installed on the top surface of the upper housing 1; a shaft collar sleeve 35 is sleeved in the mounting hole of the shaft seat 34. A shaft rod 36 horizontally penetrates through the shaft collar sleeve 35. The inner end of the shaft cap 38 penetrates through the shaft bracket 32, the shaft seat 34 and is key-connected to one end of the shaft collar sleeve 35. The outer end of the shaft cap 38 is key-connected to the shaft bracket 32. The number of shaft caps 38 is two, which are respectively connected to both ends of the shaft bracket 32, the shaft seat 34, and the shaft collar sleeve 35. Both ends of the shaft rod 36 extend to the outer ends of the two shaft caps 38; a torsion spring 37 is sleeved on the middle of the shaft rod 36. One end of the torsion spring 37 is pressed against the wall of a semi-circular groove provided in the middle of the shaft collar sleeve 35, and the other end of the torsion spring 37 is pressed against the inner wall of the shaft seat 34.

[0028] The number of the pot leg assemblies 3 is at least three and they are evenly distributed along the circumferential direction of the upper housing 1. The pot containing food is placed on the pot leg assemblies 3. The several pot leg assemblies 3 play a supporting role for the pot.

[0029] In use: The pot containing food is placed on the main pot feet 31. If the diameter of the pot is greater than the length of the main pot feet 31, the auxiliary pot rack 33 is pulled outwards, and the pot can be placed on the main pot feet 31 and the extended section of the auxiliary pot rack 33, enabling the pot foot assembly 3 of the present application to match pots of different diameters and expanding the applicable range of the alcohol stove of the present application. The auxiliary pot rack 33 and the main pot feet 31 remain relatively stable through the friction between the two. At the same time, the vertical section of the auxiliary pot rack 33 located outside the main pot feet 31 exerts a squeezing and clamping effect on the side wall of the pot body, improving the stability of the pot and preventing the pot body from tilting when the food in the pot is unevenly distributed during use. In addition, to match pots of different shapes, the present application realizes the rotatable function of the main pot feet 31 through the connection of the shaft cap 38, shaft rack 32, shaft collar 35, and shaft rod 36, and realizes the reset of the main pot feet 31 through the torsion spring 37. For example, when the pot body has a round bottom, the main pot feet 31 rotate around the shaft rod 36 as the central axis in the direction of the center of the upper housing 1, causing the main pot feet 31 to tilt inwards to match the round pot bottom, increasing the contact area between the main pot feet 31 and the pot body, and further improving the stability of the pot body on the main pot feet 31. When the pot body leaves the main pot feet 31, under the action of the torsion spring 37, the main pot feet 31 rotate in the opposite direction to the horizontal initial state.

[0030] Refer to the appendix Figure 1 , appendix Figure 2 , appendix Figure 3 , appendix Figure 4 , appendix Figure 7 and appendix Figure 8 As shown in FIGS., the adjustment handle assembly 6 includes a handle top cover 61, a handle housing 62, a main spindle 63, a bushing 64, a furnace door adjustment gear 65, a telescopic mechanism 66, an end sleeve 67, and a return spring 68.

[0031] The adjustment handle assembly 6 has two functions.

One end of the main spindle 63 is a spline shaft, and the inner wall of the bushing 64 is provided with a spline groove. The sliding key connection between the main spindle 63 and the bushing 64 is realized through the engagement of the spline shaft and the spline groove. A pin plate 631 is sleeved on the main spindle 63, and the pin plate 631 forms a flat key in the shape of a straight line. A cross-shaped keyway is provided on the outer wall of the bushing 64, and four protrusions are provided on the inner end side wall of the handle housing 62 to form a cross-shaped spline. The key connection between the handle housing 62 and the bushing 64 is realized by the engagement of the cross-shaped spline and the cross-shaped keyway. The handle top cover 61 is snap-fitted to the outer end of the handle housing 62.

[0033] The furnace door adjusting gear 65 is sleeved on the main spindle 63 in a non-connected manner and is located between the bushing 64 and the end sleeve 67 to ensure that the furnace door adjusting gear 65 will not axially move; and four protrusions are provided at the inner end of the furnace door adjusting gear 65 to form a cross-shaped keyway and a cross-shaped spline. The pin plate 631 is snap-fitted into the cross-shaped keyway formed by the four protrusions at the inner end of the furnace door adjusting gear 65 to realize the key connection between the main spindle 63 and the furnace door adjusting gear 65. The furnace door adjusting gear 65 meshes with the annular tooth groove on the outer periphery of the furnace door gear ring 43.

[0034] During use: when the handle top cover 61 and the handle housing 62 are manually rotated, since the inner end of the handle housing 62 is key-connected to the bushing 64, the bushing 64 rotates; since the bushing 64 is slidably key-connected to the main spindle 63, the main spindle 63 rotates; since the pin plate 631 is key-connected to the furnace door adjusting gear 65, the furnace door adjusting gear 65 rotates; since the furnace door adjusting gear 65 meshes with the annular tooth groove on the outer periphery of the furnace door gear ring 43, the furnace door gear ring 43 rotates, thus realizing the function of driving the furnace door gear ring 43 to rotate.

[0035] The hopper height adjustment group further includes: a telescopic mechanism 66, an end sleeve 67, and a return spring 68. Among them, the telescopic mechanism 66 plays a role in pushing the main spindle 63 to move in and out. A cross-shaped spline is provided on the inner peripheral wall of the end sleeve 67, and circumferential teeth are provided at the end of the end sleeve 67, and the circumferential teeth mesh with the strip-shaped tooth groove 531; a return rod 681 is sleeved inside the return spring 68. One end of the return rod 681 is connected to the end of the end sleeve 67, and the other end of the return rod 681 extends into the main spindle 63. The return rod 681 is coaxial with the end sleeve 67, the furnace door adjusting gear 65, and the main spindle 63.

[0036] The telescopic mechanism 66 includes two limit plate seats 660, two buttons 661, two tension springs 666, connecting plate one 662, connecting plate two 663, connecting plate three 664, connecting plate four 665, connecting plate sleeve 667, plate sleeve end cover 668, and buffer spring 669.

By inserting the arrow-shaped buckle into the square slot of the limit plate seat 660, the button 661 is connected to the limit plate seat 660. There are three hinge points on the connecting plate one 662 and the connecting plate two 663, and two hinge points on the connecting plate three 664 and the connecting plate four 665. Among them, the outer end of the connecting plate one 662 is hinge-connected to the hinge post of the lower limit plate seat 660, the middle part of the connecting plate one 662 is hinge-connected to the middle part of the connecting plate two 663, and the inner end of the connecting plate one 662 is hinge-connected to the outer end of the connecting plate four 665; the outer end of the connecting plate two 663 is hinge-connected to the hinge post of the upper limit plate seat 660, and the inner end of the connecting plate two 663 is hinge-connected to the outer end of the connecting plate three 664; the inner end of the connecting plate three 664 is hinge-connected to the hinge groove at the lower end of the connecting plate sleeve 667; the inner end of the connecting plate four 665 is hinge-connected to the hinge groove at the upper end of the connecting plate sleeve 667. The two ends of the tension spring 666 are respectively connected to the limit post of one of the limit plate seats 660 and the limit hole of the other limit plate seat 660, so as to connect the two limit plate seats 660 through the tension spring 666.

[0040] At the hinge points of the above connecting plates, it can be realized through the rotational connection of the cylindrical rod and the cylindrical hole. Specifically, as shown in the attached drawings, the outer end and the middle part of the connecting plate one 662 are cylindrical holes, and the inner end is a cylindrical rod, and the cylindrical rod is located on the upper surface of the connecting plate one 662; the outer end of the connecting plate two 663 is a cylindrical hole, the middle part and the inner end are cylindrical rods, and the cylindrical rods are located on the lower surface of the connecting plate two 663; the outer end of the connecting plate three 664 is a cylindrical hole, the inner end is a cylindrical rod, and the cylindrical rod is located on the lower surface of the connecting plate three 664; the outer end of the connecting plate four 665 is a cylindrical hole, the inner end is a cylindrical rod, and the cylindrical rod is located on the upper surface of the connecting plate four 665. The connecting plate one 662, the connecting plate two 663, the connecting plate three 664, and the connecting plate four 665 are common telescopic frame structures made according to the instability of the parallelogram.

[0041] On the inner wall of the handle top cover 61, there are longer outer teeth located in the middle, and four inner teeth symmetrically distributed up and down on both sides of the outer teeth. The handle top cover 61 is connected to the handle housing 62 by the outer teeth being clamped on the handle housing 62; the two upper inner teeth are clamped on the outer walls at both ends of the upper limit plate seat 660, and the two lower inner teeth are clamped on the outer walls at both ends of the lower limit plate seat 660, so as to play a limiting role on the two limit plate seats 660, and the limit plate seat 660 can be prevented from axially moving. Here, the axial direction refers to the axial direction of the entire telescopic mechanism 66, which can be simply regarded as the central axis direction of the handle top cover 61.

[0042] When in use, when it is necessary to adjust the height of the main hopper 51, manually press two buttons 661 simultaneously. The buttons 661 respectively push the outer ends of two limit plate seats 660 to move towards each other. The first connecting plate 662 and the second connecting plate 663 rotate around their middle hinge points, and then drive the third connecting plate 664 and the fourth connecting plate 665 to rotate. The link telescopic mechanism composed of the first connecting plate 662, the second connecting plate 663, the third connecting plate 664, and the fourth connecting plate 665 extends, thereby pushing the connecting plate sleeve 667 to move inward, and pushing the main spindle 63 inward through the plate sleeve end cover 668. The main spindle 63 slides inward relative to the sleeve 64, and the pin plate 631 disengages from the cross-shaped keyway of the furnace door adjusting gear 65. When the main spindle 63 moves inward to the limit position, the pin plate 631 is clamped in the keyway of the cross-shaped spline on the inner wall of the end sleeve 67, thereby realizing the key connection between the main spindle 63 and the end sleeve 67; While pressing the two buttons 661, rotate the handle top cover 61 and the handle housing 62. Then, drive the sleeve 64, the main spindle 63, and the end sleeve 67 to rotate by using the handle housing 62, and drive the guide frame 53 to move up and down through the meshing of the circumferential teeth at the inner end of the end sleeve 67 and the strip-shaped tooth groove 531, thereby realizing the effect of driving the main hopper 51 to move up and down.

[0043] After releasing the two buttons 661 and stopping rotating the handle top cover 61 and the handle housing 62, under the action of the return spring 68, the main spindle 63 is pushed outward to reset. The main spindle 63 pushes the plate sleeve end cover 668, the buffer spring 669, and the connecting plate sleeve 667 to reset the limit plate seat 660, the button 661, the first connecting plate 662, the second connecting plate 663, the third connecting plate 664, and the fourth connecting plate 665, and the tension spring 666 also has the effect of pushing the limit plate seat 660 to reset.

[0044] At the same time, the return spring 68 and the return rod 681 also have the function of assisting the pin plate 631 to reset and engage with the cross-shaped keyway of the furnace door adjusting gear 65. Since the pin plate 631 disengages from the cross-shaped keyway of the furnace door adjusting gear 65 during the process of driving the main spindle 63 to move, when the pin plate 631 returns, it may not be able to align and engage with the cross-shaped keyway of the furnace door adjusting gear 65 at one time. At this time, only need to rotate the handle top cover 61 and the handle housing 62. When rotating the handle top cover 61 and the handle housing 62, the pin plate 631 rotates. Under the push of the return spring 68, as long as the pin plate 631 aligns with the cross-shaped keyway of the furnace door adjusting gear 65, it can be pushed into the cross-shaped keyway, and the key connection between the main spindle 63 and the furnace door adjusting gear 65 is realized again. Similarly, the re-key connection method between the pin plate 631 and the keyway of the cross-shaped spline inside the end sleeve 67 is the same. Only need to rotate the handle top cover 61 and the handle housing 62 until their key connection is achieved.

[0045] Refer to the appendix Figure 10As shown, three brackets 7 are provided in the present application, wherein an adjusting handle assembly 6 is installed in one of the brackets 7, and an end sleeve 67 of the adjusting handle assembly 6 is a main driving component; the three brackets 7 are evenly distributed around the furnace door seat ring 42, providing stable support for the furnace door seat ring 42.

[0046] In summary, the overall usage of this application is: The pot is placed on the main pot foot 31, and the auxiliary pot rack 33 is pulled out to match the large diameter pot body. At the same time, the vertical section of the auxiliary pot rack 33 is clamped on the outer wall of the pot body to improve the stability of the pot body; the main pot foot 31 is rotated around the shaft 36 by turning it to adjust the inclination of the main pot foot 31, so that the main pot foot 31 can match pot bodies of different shapes, so as to increase the contact area between the main pot foot 31 and the pot body, and further improve the stability of the pot body.

[0047] When the gap of the furnace door paddle 41 needs to be adjusted to adjust the flame size, the handle top cover 61 and the handle housing 62 can be rotated; When it is necessary to adjust the height of the main hopper 51 to match the volume of the alcohol block and to reduce the distance between the flame and the bottom of the pot, the two buttons 661 are squeezed at the same time and the handle top cover 61 and the handle shell 62 are rotated.
