Vertical heating stove with multi-stage adjustment function of stove head

Abstract

This invention discloses a vertical heating stove with multi-position adjustable burner head, comprising a support base, a lifting mechanism, an angle rotation mechanism, a suspension mechanism, and a shielding mechanism. The angle rotation mechanism is located at the upper end of the lifting mechanism. The burner head is rotatably connected to a fixed column via a first rotating seat. The suspension mechanism selectively engages with a limiting frame to achieve multi-position pitch adjustment of the burner head. The shielding mechanism moves with the height change of the lifting mechanism to shield or avoid certain angle positioning parts on the limiting frame. When the burner head is raised to a high position, the shielding mechanism restricts the burner head from entering a large pitch angle state. When the burner head is already in a large pitch angle state, the shielding mechanism, in conjunction with the limiting frame, restricts the lifting mechanism from further raising. Simultaneously, through a support state detection and tilt response structure, unfavorable pitch positions can be further restricted based on local support differences in the base or the slope direction.

Description

Technical Field

[0001] This invention belongs to the technical field of heating equipment, and in particular relates to a vertical heating stove with multi-level adjustment function of the burner head. Background Technology

[0002] In settings such as terraces, courtyards, outdoor stalls, semi-open dining areas, and temporary work sites, upright heaters are typically placed around the user and radiate heat to the target area through the burner head. Due to differences in users' standing height, sitting height, and heating distance, the burner head needs to be adjusted in height and tilt to direct the heat radiation towards the upper part of the body, the vicinity of the table, or a specific work area.

[0003] Currently, the height and tilt adjustments of vertical boilers are usually independent. Ground conditions in such scenarios are not always flat and continuous; for example, grass, brick floors, tiled surfaces, courtyard drainage slopes, and temporary paved surfaces may exhibit localized areas of suspension, subsidence, or uneven load-bearing. When the boiler is in a low position, the lever arm of the burner head relative to the supporting base is short, and tilt adjustment has little impact on the overall stability. However, when the burner head is raised, its mass and connecting structures create a higher center of gravity relative to the base. If the burner head is still allowed to enter a large tilt or elevation angle at this point, the center of gravity of the entire unit will shift forward or backward.

[0004] Therefore, when the base of the existing structure is not evenly grounded or is placed at an angle, it is prone to problems such as being in a high position and having a large pitch angle at the same time, as well as insufficient support. Summary of the Invention

[0005] The purpose of this invention is to provide a vertical heating stove with multi-level adjustment of the burner head, in order to solve the technical problem that the height adjustment and pitch adjustment of existing vertical heating stoves are independent of each other, resulting in insufficient support of the whole machine and the risk of tipping over when the burner head is in a high position and enters a large pitch angle.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is described in the claims.

[0007] A vertical heating stove with multi-position adjustable burner head includes a support base and a lifting mechanism mounted on the support base.

[0013] According to some embodiments, the system further includes a first adjustment mechanism, which comprises: a support box fixedly installed at the bottom of the support base, with a rotating plate rotatably installed inside; multiple counterweight boxes, each connected to the support box via a first spring and each connected to the rotating plate via a third pull rope; two sliding rods, each fixedly installed on the support box, with a first sliding plate and a second sliding plate slidably connected thereon respectively; a first pull rope, one end of which is fixedly connected to the second sliding plate and the other end of which is fixedly connected to the rotating plate; and a second pull rope, one end of which is fixedly connected to the first sliding plate and the other end of which is fixedly connected to the rotating plate.

[0015] According to some embodiments, the first shielding mechanism further includes: a shielding box, which is fixedly connected to the first threaded plate and slidably connected to the shielding plate; a third spring, one end of which is fixedly connected to the shielding plate and the other end of which is fixedly connected to the shielding box; and a second connecting hose, one end of which is connected to the shielding box and the other end of which is connected to a liquid storage tank in the first extension box; the structure of the second shielding mechanism is the same as that of the first shielding mechanism, and the second connecting hose on the second shielding mechanism is connected to another liquid storage tank in the first extension box.

[0016] According to some embodiments, the device further includes a swing mechanism comprising: a second rotating shaft rotatably mounted on the support box, on which a counterweight rotating block and a fourth bevel gear are fixedly mounted; a second rotating plate fixedly mounted on the support box, on which a worm gear is rotatably mounted; a third bevel gear fixedly mounted on the worm gear and meshing with the fourth bevel gear; a first rotating plate fixedly mounted on the support box, on which a second positive and negative screw is rotatably mounted; two second threaded plates, both threadedly connected to the second positive and negative screws and slidably connected to the support box; a worm gear fixedly mounted on the second positive and negative screws and meshing with the worm gear; two protrusions respectively connected to the support box via two fourth springs and fixedly connected to the fourth and fifth pull ropes respectively; and two bolts respectively threadedly connected to the two protrusions.

This invention transmits height changes to the angle rotation mechanism through a lifting mechanism, and through the cooperation of a limiting frame and a baffle plate, allows the burner head to select more pitch positions when it is in a low position, and blocks some large pitch angle positioning positions when it is in a high position; when the burner head is already in a large pitch angle state, the baffle plate and the limiting frame cooperate to restrict the lifting mechanism from rising further, thereby forming a safety boundary between height adjustment and pitch adjustment.

[0018] 2. The present invention uses the selective positioning cooperation of the suspension frame and the limiting frame, so that the user can first rotate the suspension frame to release the positioning, and then switch the pitch position of the furnace head by pushing and pulling the suspension frame; the suspension spring provides auxiliary support between the furnace head and the suspension mechanism, which helps to reduce the instantaneous downward pressure during the process of releasing and repositioning.

[0019] 3. The present invention drives the first extrusion block to move through the first extension plate, so that the working fluid enters the second mounting box through the first connecting hose, and drives the two first threaded plates to move towards each other or away from each other through the moving frame, gear frame, spur gear, first rotating shaft, first bevel gear, second bevel gear and first positive and negative screw in sequence, so that the positions of the first shielding mechanism and the second shielding mechanism are adjusted according to the change of the furnace head height.

[0020] 4. The present invention identifies local support differences at the bottom through a support box, a counterweight box, a rotating plate, a sliding plate, and a pull rope, and delivers the working fluid in the corresponding storage tank to the first or second shielding mechanism through a second squeezing block; combined with the response of the counterweight rotating block in the swing mechanism to the tilt direction, it can directionally restrict the selectable gear corresponding to the unfavorable pitch direction.

[0036] To make the above-mentioned objects, features, and advantages of the present invention clearer and more understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the protection scope of the present invention.

[0037] This invention will be described in detail with reference to the accompanying drawings. In the detailed description of the embodiments of this invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged without adhering to the general scale, and the accompanying drawings are merely examples and should not limit the scope of protection of this invention. Furthermore, in actual fabrication, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0038] At the same time, it should be noted in the description of the present invention that the terms "first", "second" or "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] Example 1: As Figures 1 to 4 , Figure 7 and Figure 9 As shown, this embodiment provides a vertical heating stove with multi-level burner adjustment function, including a support base 100 and a lifting mechanism 110 mounted on the support base 100, and also includes an angle rotation mechanism 140. The angle rotation mechanism 140 is located at the upper end of the lifting mechanism 110 and includes a fixed column 144, a burner head 141, a first rotating seat 145, and a limiting frame 146. The fixed column 144 is connected to the upper end of the lifting mechanism 110. A suspension mechanism 150 is rotatably mounted on the burner head 141. The first rotating seat 145 is rotatably connected to the fixed column 144 and fixedly connected to the burner head 141. The limiting frame 146 is located on the pitch and rotation path of the burner head 141 and forms multiple angle positioning parts; the suspension... Spring 143 acts between burner head 141 and suspension mechanism 150 to provide auxiliary support force to burner head 141; first blocking mechanism 160 is disposed between lifting mechanism 110 and limiting frame 146. First blocking mechanism 160 includes blocking plate 163. Blocking plate 163 is used to block or avoid part of the angle positioning part on limiting frame 146 as the height of lifting mechanism 110 changes; when lifting mechanism 110 adjusts angle rotation mechanism 140 to high position, blocking plate 163 blocks part of angle positioning part on limiting frame 146 to limit burner head 141 from entering large pitch angle state; when burner head 141 is in large pitch angle state, blocking plate 163 cooperates with limiting frame 146 to limit lifting mechanism 110 from continuing to rise.

[0040] In this document, "high position" refers to the position where the extension height of the first extension plate 111 relative to the first fixing box 112 reaches or exceeds a preset height threshold; "large pitch angle state" refers to the state where the absolute value of the pitch angle of the burner head 141 relative to the horizontal reference plane reaches or exceeds a preset angle threshold. The multiple angle positioning parts on the limiting frame 146 can be divided into conventional angle positioning parts and large pitch angle positioning parts according to the pitch angle size.

[0041] The support base 100 provides ground support, and the lifting mechanism 110 transmits height changes to the fixed column 144, which then supports the burner head 141 via the first rotating seat 145. The burner head 141 does not rely directly on friction to stop during pitching; instead, it obtains its position through multiple angle positioning parts on the limiting frame 146. Since the mass of the burner head 141 increases relative to the support base 100 after it rises, allowing the burner head 141 to enter larger pitch or tilt angles would reduce the overall stability margin in the longitudinal direction. After the baffle plate 163 is positioned between the lifting mechanism 110 and the limiting frame 146, it can enter part of the positioning path of the limiting frame 146 when the height increases, preventing the corresponding angle positioning part from being selected by the suspension mechanism 150. Conversely, when the burner head 141 is already at a large pitch angle, the positional relationship between the baffle plate 163 and the limiting frame 146 will prevent the lifting mechanism 110 from further sending the angle rotation mechanism 140 to a higher position. Therefore, the height state and the angle state are not two isolated actions, but rather they are mutually verified at the contact boundary between the limit bracket 146 and the baffle 163, allowing the user to make normal multi-level adjustments without continuing to enter an unsuitable angle range in the high position.

[0042] The suspension spring 143 is not used solely for resetting, but rather acts between the burner head 141 and the suspension mechanism 150. When the burner head 141 is tilted, the suspension spring 143 bears a portion of the rotational torque generated by the burner head 141's center of gravity shifting away from the first rotating seat 145, so that the suspension mechanism 150 does not need to fully bear the instantaneous downward pressure generated by the burner head 141's own weight when releasing and repositioning. Thus, even after the baffle plate 163 partially blocks the angle positioning section, the burner head 141 can still switch between permissible positioning sections, and the force direction of the limiting bracket 146 is more clearly defined, reducing the possibility of oblique compression of the positioning section edge. A physical boundary between height and angle is formed between the baffle plate 163 and the limiting bracket 146, allowing the user to perceive the end point of the adjustable range through the structural obstruction during raising or lowering.

[0043] Example 2: Figures 2 to 4 As shown, based on Embodiment 1, the angle rotation mechanism 140 further includes a control cabinet 142, which is fixedly installed on the lifting mechanism 110 and fixedly connected to the limiting frame 146; the suspension mechanism 150 includes a suspension frame 151, which is rotatably connected to the burner head 141 and selectively positioned with the limiting frame 146. The suspension frame 151 is released from positioning by rotating relative to the burner head 141, and its position with the limiting frame 146 is switched by pushing and pulling to adjust the pitch angle of the burner head 141.

[0044] The burner head 141 typically has a certain length. A first rotating seat 145 is positioned between the burner head 141 and the fixed tube column 144. Both the front and rear ends of the burner head 141 generate torque relative to the first rotating seat 145. When the user directly pushes the burner head 141 to tilt, if the positioning structure is not first released, the positioning part on the limit frame 146 is easily subjected to lateral scraping, and the feel of positioning switching is unstable. In this embodiment, the suspension frame 151 is configured as a rotatable component. The suspension frame 151 first rotates relative to the burner head 141, disengaging its positioning engagement with the limit frame 146. Then, the user pushes or pulls the suspension frame 151 as needed, causing the burner head 141 to change its posture around the first rotating seat 145. When the suspension frame 151 is pushed, the burner head 141 can change in the tilt direction; when the suspension frame 151 is pulled, the burner head 141 can change in the depression direction. After reaching the target position, the suspension frame 151 re-engages with another positioning position of the limit frame 146, and the burner head 141 stops at the corresponding tilt position.

[0045] The control cabinet 142 is fixedly connected to the limit frame 146, preventing the limit frame 146 from drifting with the rotation of the suspension frame 151 and maintaining a relatively stable positioning reference. One end of the suspension spring 143 engages with the burner head 141, and the other end engages with the suspension mechanism 150. It provides upward auxiliary support when the suspension frame 151 rotates to release the positioning, preventing the burner head 141 from suddenly dropping due to the instantaneous release of the positioning. When the suspension frame 151 is pushed or pulled to switch positions, the suspension spring 143 can also reduce the user's need to continuously support the weight of the front end of the burner head 141. The baffle plate 163 is still located outside the selectable positioning range of the suspension frame 151. When the baffle plate 163 occupies part of the positioning path, the suspension frame 151 can only engage with the remaining positioning position, thereby further implementing the height limitation of Embodiment 1 into the manual angle adjustment process.

[0046] Example 3: Figures 4 to 10 As shown, based on Embodiments 1 and 2, the lifting mechanism 110 includes a first fixed box 112, a motor 113, a first screw 114, and a first extension plate 111. The first fixed box 112 is fixedly mounted on the support base 100, the motor 113 is fixedly mounted inside the first fixed box 112, the first screw 114 is fixedly connected to the power output shaft of the motor 113, and the first extension plate 111 is slidably mounted on the first fixed box 112 and fixedly connected to the fixed column 144. The first extension plate 111 is also threadedly connected to the first screw 114. When the motor 113 drives the first screw 114 to rotate, the first extension plate 111 moves along the first fixed box 112, and the fixed column 144, control cabinet 142, and furnace head 141 rise and fall with the first extension plate 111.

[0047] To allow changes in height to simultaneously alter the permissible angle range, the lifting mechanism 110 further includes a second fixed box 117, a first pressing block 118, a connecting rod 116, and a connecting block 115. The second fixed box 117 is fixedly mounted on the first fixed box 112. The first pressing block 118 is slidably mounted inside the second fixed box 117. The connecting rod 116 is fixedly mounted on the first pressing block 118 and slidably connected to the second fixed box 117. The connecting block 115 is fixedly mounted on the connecting rod 116 and fixedly connected to the first extension plate 111. When the first extension plate 111 rises, it moves the first pressing block 118 via the connecting block 115 and the connecting rod 116. The first pressing block 118 presses the working fluid in the second fixed box 117, causing the working fluid to enter the first connecting hose 1595. The other end of the first connecting hose 1595 is connected to the second mounting box 153. After the working fluid enters the second mounting box 153, it pushes the moving frame 1593 to move against the second spring 1594. The moving frame 1593 drives the gear frame 1592 to move. The gear frame 1592 drives the spur gear 1591 to rotate. The spur gear 1591 drives the first rotating shaft 157 to rotate. The first rotating shaft 157 causes the first positive and negative screw 155 to rotate through the second bevel gear 156 and the first bevel gear 154.

[0048] The first mounting box 152 is fixedly mounted on the suspension bracket 151, and the mounting bracket 159 is fixedly mounted on the first mounting box 152. The mounting bracket 159 is fixedly connected to the second mounting box 153. The first positive and negative screw 155 is rotatably mounted inside the first mounting box 152, and the two first threaded plates 158 are respectively threaded to both ends of the first positive and negative screw 155. Since the threads at both ends of the first positive and negative screw 155 turn in opposite directions, when the first positive and negative screw 155 rotates, the two first threaded plates 158 move closer to or further away from each other. The first shielding mechanism 160 and the second shielding mechanism 170 are respectively installed on the two first threaded plates 158. When the two first threaded plates 158 approach each other, the first shielding mechanism 160 and the second shielding mechanism 170 move synchronously towards the middle of the limiting frame 146 or the corresponding positioning area, thereby shielding more positioning positions corresponding to the large pitch angle. When the two first threaded plates 158 move away from each other, the first shielding mechanism 160 and the second shielding mechanism 170 avoid the corresponding positioning positions, so that the burner head 141 has a larger range of selectable angles in the low position state.

[0049] If the angle is limited only by a fixed limiting structure, the adjustable range in the low position will be unnecessarily constrained; if it is not limited at all, the angle range in the high position may be too wide. The lifting displacement of the first extension plate 111 is gradually converted into a change in distance between the first blocking mechanism 160 and the second blocking mechanism 170 through the first extrusion block 118, working fluid, moving frame 1593, gear frame 1592, and first positive and negative screws 155. At a lower height, the blocking mechanism is in a yielding position, allowing the suspension frame 151 to select more positioning positions; at a higher height, the blocking mechanism gradually approaches and covers part of the positioning positions, narrowing the selectable angle range with height. When the motor 113 reverses, the first extension plate 111 descends, the first extrusion block 118 moves back, the second spring 1594 pushes the moving frame 1593 to reset, the working fluid returns to the second fixed box 117, the first positive and negative screws 155 reverse their movement, the two first threaded plates 158 move away, the blocking range is released, and initial space is provided for the next lifting and angle adjustment. The first connecting hose 1595 allows for relative installation freedom between the lifting mechanism 110 and the suspension mechanism 150, eliminating the need for a rigid long rod to cross the rotation area when the burner head 141 is tilted.

[0050] Example 4: Figure 7 , Figure 8 , Figure 11 and Figure 12 As shown, based on the aforementioned embodiment, the vertical heating furnace further includes a first adjustment mechanism 120 and an auxiliary support mechanism 130. The first adjustment mechanism 120 includes a support box 121, a rotating plate 125, multiple counterweight boxes 127, a first spring 126, a third pull rope 1291, a slide bar 123, a first sliding plate 122, a second sliding plate 124, a first pull rope 128, and a second pull rope 129. The support box 121 is fixedly installed at the bottom of the support base 100, the rotating plate 125 is rotatably installed inside the support box 121, and the multiple counterweight boxes 127 are respectively connected to the support box 121 through the first spring 126 and connected to the rotating plate 125 through the third pull rope 1291. Two slide rods 123 are fixedly installed on the support box 121. The first slide plate 122 and the second slide plate 124 are slidably connected to the corresponding slide rods 123. One end of the first pull rope 128 is fixedly connected to the second slide plate 124 and the other end is fixedly connected to the rotating plate 125. One end of the second pull rope 129 is fixedly connected to the first slide plate 122 and the other end is fixedly connected to the rotating plate 125.

[0051] When the support base 100 is placed on grass, brick joints, or uneven ground, only a portion of the bottom of the support box 121 may be in full contact with the ground. The counterweight box 127 corresponding to the area in full contact with the ground is supported by the ground and its movement is restricted. The counterweight box 127 that is not in full contact with the ground moves downward relative to the support box 121 under its own weight, and pulls the rotating plate 125 through the third pull rope 1291. If the counterweight box 127 in the corresponding area in front of the burner head 141 moves downward too much, the rotating plate 125 will deflect forward, indicating that the actual support on the rear side is insufficient. At this time, continuing to adjust the forward tilt angle will cause the center of force to move further forward. After the rotating plate 125 deflects, it pulls the corresponding first sliding plate 122 or second sliding plate 124 through the first pull rope 128 or the second pull rope 129, so that the bottom support state is converted into sliding plate displacement.

[0052] The auxiliary support mechanism 130 includes a third fixed box 134, a first extension box 131, two second compression blocks 132, a fourth pull rope 133, and a fifth pull rope 135. The first extension box 131 is mounted on the third fixed box 134 and contains two liquid storage tanks. The two second compression blocks 132 are slidably installed in the two liquid storage tanks respectively. One end of the fourth pull rope 133 is fixedly connected to one of the second compression blocks 132, and the other end is fixedly connected to the first sliding plate 122. One end of the fifth pull rope 135 is fixedly connected to the other second compression block 132, and the other end is fixedly connected to the second sliding plate 124. When the first sliding plate 122 or the second sliding plate 124 is pulled, the corresponding pull rope pulls the corresponding second compression block 132, causing the second compression block 132 to compress the working fluid in the liquid storage tank.

[0053] The first shielding mechanism 160 also includes a shielding box 161, a third spring 162, and a second connecting hose 164. The shielding box 161 is fixedly connected to the first threaded plate 158 and slidably connected to the shielding plate 163. One end of the third spring 162 is fixedly connected to the shielding plate 163, and the other end is fixedly connected to the shielding box 161. One end of the second connecting hose 164 is connected to the shielding box 161, and the other end is connected to the corresponding liquid storage tank. The second shielding mechanism 170 has the same working structure as the first shielding mechanism 160 and is connected to another liquid storage tank through another second connecting hose 164. When the ground support status indicates insufficient support on the front or rear side, the working fluid in the corresponding liquid storage tank enters the first shielding mechanism 160 or the second shielding mechanism 170, causing the corresponding shielding plate 163 to extend and further shield the positioning area on the limit frame 146 corresponding to the unfavorable pitch direction. After the working fluid pressure is released, the third spring 162 pulls the shielding plate 163 to retract, restoring the shielding mechanism to the avoidance state.

[0054] When the burner head 141 is at the same height, if the support base 100 is stably grounded around its entire circumference, the extension of the baffle plate 163 is mainly determined by the height. If the support box 121 detects insufficient support on one side, the second pressing block 132 on the corresponding side drives the corresponding baffle mechanism, reducing the pitch range associated with that direction. After the counterweight box 127 is distributed along the support box 121, it can distinguish the landing state at multiple positions on the edge of the base, reducing the impact of a single point of contact on the overall stability judgment.

[0055] Example 5: Figure 12 and Figure 13 As shown, based on the aforementioned embodiment, the vertical heating furnace further includes a swing mechanism 180. The swing mechanism 180 includes a second rotating shaft 1891, a counterweight rotating block 1893, a fourth bevel gear 1892, a second rotating plate 188, a worm gear 187, a third bevel gear 189, a first rotating plate 184, a second positive and negative screw 185, two second threaded plates 183, a worm wheel 186, two protrusions 181, two fourth springs 182, and two bolts 1894. The second rotating shaft 1891 is rotatably mounted on the support box 121, and the counterweight rotating block 1893 and the fourth bevel gear 1892 are fixedly mounted on the second rotating shaft 1891. The second rotating plate 188 is fixedly mounted on the support box 121, the worm gear 187 is rotatably mounted on the second rotating plate 188, and the third bevel gear 189 is fixedly mounted on the worm gear 187 and meshes with the fourth bevel gear 1892. The first rotating plate 184 is fixedly mounted on the support box 121. The second positive and negative screws 185 are rotatably mounted on the first rotating plate 184. The worm gear 186 is fixedly mounted on the second positive and negative screws 185 and meshes with the worm gear 187. The two second threaded plates 183 are threadedly connected to the second positive and negative screws 185 and slide in cooperation with the support box 121. The two protrusions 181 are respectively connected to the support box 121 through two fourth springs 182, and are respectively fixedly connected to the fourth pull rope 133 and the fifth pull rope 135. The two bolts 1894 are respectively threadedly connected to the two protrusions 181.

[0056] In this embodiment, the counterweight rotating block 1893 rotates around the second rotating shaft 1891. When the support box 121 tilts with the ground, the counterweight rotating block 1893 deflects relative to the support box 121 under the action of gravity. The second rotating shaft 1891 drives the fourth bevel gear 1892 to rotate. The fourth bevel gear 1892 drives the worm gear 187 to rotate through the third bevel gear 189. The worm gear 187 drives the worm wheel 186 and the second positive and negative screws 185 to rotate. Since the threads at both ends of the second positive and negative screws 185 turn in opposite directions, the two second threaded plates 183 will move closer or further apart, thereby changing the movable space of the protrusion 181 under the action of the fourth spring 182.

[0057] When the counterweight rotating block 1893 deflects in one direction, with the corresponding bolt 1894 released from constraint, the protrusion 181 cooperating with the fourth spring 182 on that side moves and pulls the fifth pull rope 135. The fifth pull rope 135 then drives the corresponding second extrusion block 132, causing the working fluid in the reservoir to enter the extrusion box 161 of the first extrusion mechanism 160, pushing the extrusion plate 163 to block the positioning area related to the corresponding elevation angle. When the counterweight rotating block 1893 deflects in the opposite direction, the protrusion 181 on the other side pulls the fourth pull rope 133, which drives another second extrusion block 132, causing the working fluid to enter the second extrusion mechanism 170, blocking the positioning area related to the corresponding depression angle. There is a large transmission resistance between the worm gear 187 and the worm wheel 186. When the counterweight rotating block 1893 is subjected to short-term shaking, the second forward and reverse screws 185 are less likely to produce frequent reciprocating displacement, keeping the movement of the protrusion 181 and the pull rope relatively stable. The swing mechanism 180 converts the slope direction into the action direction of the corresponding side shielding mechanism, so that the height restriction, ground local support restriction and tilt direction restriction form a progressive coordination.

[0058] Overall working principle: Place the support base 100 in the use position so that the support box 121 contacts the ground, the burner head 141 faces the target heating area, the counterweight box 127 is in the initial position under the action of the first spring 126, the suspension bracket 151 cooperates with a certain positioning position of the limit bracket 146, and the baffle plate 163 is kept in the initial avoidance state under the action of the third spring 162.

[0059] When the height needs to be adjusted, the motor 113 is started. The motor 113 drives the first screw 114 to rotate. The first screw 114 drives the first extension plate 111 to move along the first fixed box 112 through the thread action. The first extension plate 111 drives the fixed column 144, control cabinet 142, first rotating seat 145, furnace head 141 and suspension mechanism 150 to be raised or lowered as a whole.

[0060] When the first extension plate 111 rises, the connecting block 115 moves with the first extension plate 111. The connecting block 115 drives the first extrusion block 118 to move in the second fixed box 117 through the connecting rod 116. The first extrusion block 118 extrudes the working fluid. The working fluid enters the second mounting box 153 through the first connecting hose 1595 and pushes the moving frame 1593. The moving frame 1593 drives the gear frame 1592 to move. The gear frame 1592 drives the spur gear 1591 and the first rotating shaft 157 to rotate. The first rotating shaft 157 drives the first positive and negative screws 155 through the second bevel gear 156 and the first bevel gear 154, so that the two first threaded plates 158 move closer to each other. The first blocking mechanism 160 and the second blocking mechanism 170 then move closer to the partial positioning area of ​​the limiting frame 146.

[0061] When it is necessary to adjust the pitch angle of the burner head 141, the user rotates the suspension bracket 151 to disengage the suspension bracket 151 from the limiting bracket 146. Then, the user pushes the suspension bracket 151 to rotate the burner head 141 in the pitch direction, or pulls the suspension bracket 151 to rotate the burner head 141 in the depression direction. During this process, the suspension spring 143 provides auxiliary support to the burner head 141. After reaching the target angle, the user releases or rotates the suspension bracket 151 to re-engage the suspension bracket 151 with another positioning position of the limiting bracket 146.

[0062] When the burner head 141 has been raised to the high position, the first blocking mechanism 160 and the second blocking mechanism 170 have blocked part of the positioning position on the limiting frame 146, and the suspension frame 151 cannot enter the blocked large pitch angle position; when the burner head 141 is in a large pitch angle state, the cooperation position between the blocking plate 163 and the limiting frame 146 prevents the first extension plate 111 from continuing to raise the angle rotation mechanism 140.

[0063] If the height needs to be lowered, the motor 113 reverses, the first screw 114 drives the first extension plate 111 to descend, the connecting block 115 and the connecting rod 116 drive the first pressing block 118 to move back, the second spring 1594 pushes the moving frame 1593 to reset, the working fluid returns from the second mounting box 153 to the second fixed box 117 via the first connecting hose 1595, the gear frame 1592 drives the spur gear 1591 to rotate in the opposite direction, the first forward and reverse screws 155 move in the opposite direction, the two first threaded plates 158 move away, and the first blocking mechanism 160 and the second blocking mechanism 170 release part of the positioning position.

[0064] When the bottom of the support box 121 is partially suspended or partially sunken, the counterweight box 127, which is not in full contact with the ground, moves downward under its own weight. The third pull rope 1291 pulls the rotating plate 125 to deflect. The rotating plate 125 pulls the second slide plate 124 or the first slide plate 122 through the first pull rope 128 or the second pull rope 129. The second slide plate 124 pulls the corresponding second compression block 132 through the fifth pull rope 135. The first slide plate 122 pulls another second compression block 132 through the fourth pull rope 133. The corresponding second compression block 132 squeezes the working fluid in the liquid storage tank, so that the working fluid enters the first shielding mechanism 160 or the second shielding mechanism 170. The shielding plate 163 extends and restricts the pitch position in the corresponding direction.

[0065] When the device is placed on an inclined surface, the counterweight rotating block 1893 deflects relative to the support box 121 in the direction of gravity. The counterweight rotating block 1893 drives the second threaded plate 183 to move via the second rotating shaft 1891, the fourth bevel gear 1892, the third bevel gear 189, the worm 187, the worm wheel 186, and the second positive and negative screws 185. The second threaded plate 183 changes the movable state of the protrusion 181. When the corresponding bolt 1894 is released from constraint, the protrusion 181 pulls the fourth pull rope 133 or the fifth pull rope 135 under the action of the fourth spring 182, thereby driving the corresponding second pressing block 132 and the corresponding blocking mechanism, so that the unfavorable pitch position corresponding to the slope direction is blocked.
