Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a lifting base and a pellet heater. Background Technology

[0002] Pellet heaters are heating devices that use compressed biomass pellets, such as wood chips, as fuel. In recent years, they have become increasingly popular in homes and offices. After the biomass pellets enter the furnace, with a sufficient supply of oxygen, the organic matter in the pellets undergoes an oxidation reaction, releasing heat energy.

[0003] Currently, most outdoor heaters on the market rely on two main design technologies for their movement and braking functions. One type involves installing two ground-level casters at the rear of the base. To move the heater, the entire unit must be tilted backward until the base is completely off the ground, allowing the two casters to bear the load and contact the ground individually. Moving the unit is then accomplished by pushing. While this design meets basic movement needs, it has significant limitations. The tilting operation is cumbersome, and the upper part of the unit, being the core heat dissipation area, remains consistently hot, posing a safety risk when moved directly. The other design uses four casters with brakes on the base. Movement and fixation are achieved by adjusting the brakes on these casters. However, this design lacks ease of operation, requiring manual adjustment of at least two, or even all four, casters, making the process relatively cumbersome. It's worth noting that both designs share the common problem of exposed casters, which negatively impacts the overall appearance and aesthetics of the product.

[0004] Therefore, finding a way to change the current situation where particle heaters are not convenient to handle and operate and affect the overall structure of the product has become a common practice for those skilled in the art. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The purpose of this utility model is to provide a lifting base and a pellet heater to solve the problems existing in the above-mentioned related technologies, improve the convenience of handling and operation of the pellet heater, reduce the labor burden of operators, and improve the moving efficiency of the pellet heater.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1 This embodiment provides a lifting base 100, please refer to... Figures 1-4The device includes a base housing 1 and a lifting unit. The base housing 1 has an open bottom structure, and the top of the base housing 1 can be connected to the heater body 200. The lifting unit includes an upper frame 2, a lower frame 3, a connecting component, and a traveling wheel 4. The upper frame 2 is connected to the base housing 1, and the upper frame 2 is connected to the lower frame 3 via the connecting component. The traveling wheel 4 is connected to the lower frame 3. The connecting component can adjust the distance between the upper frame 2 and the lower frame 3 so that the traveling wheel 4 contacts the ground and lifts the base housing 1.

[0025] The lifting base 100 of this utility model has a base housing 1 that can be connected to the heater body 200. In the lifting unit, the connecting component adjusts the distance between the upper frame 2 and the lower frame 3, allowing the lifting unit to extend and retract. When the lifting unit is in the retracted state, it is located in the inner cavity of the base housing 1, and the base housing 1 can contact the ground. The traveling wheels 4 are located inside the base housing 1, ensuring the structural integrity and aesthetics of the lifting base 100 and the pellet heater. When the connecting component adjusts the relative position of the upper frame 2 and the lower frame 3 to increase the distance between them, the lifting unit is adjusted to the extended state, thereby lifting the base housing 1 and making the traveling wheels 4 at the bottom of the lower frame 3 contact the ground. The traveling wheels 4 can be used to easily move the heater body 200, making it convenient for users to move it to a suitable usage position in the yard, or to move it to a storage position when not in use. This improves the ease of operation of the pellet heater, reduces the workload of operators, increases the efficiency of moving the pellet heater, and effectively prevents the heater body 200 from tilting during movement, thus improving the safety factor of moving the pellet heater.

[0026] In this specific embodiment, the connecting assembly includes a first support rod 5 and a second support rod 6. The first support rod 5 and the second support rod 6 are hinged together to form an X-shaped structure. One end of the first support rod 5 is hinged to the upper frame 2, and the other end of the first support rod 5 is slidably connected to the lower frame 3 and can rotate relative to the lower frame 3. One end of the second support rod 6 is hinged to the lower frame 3, and the other end of the second support rod 6 is slidably connected to the upper frame 2 and can rotate relative to the upper frame 2. The sliding ends of the first support rod 5 and the second support rod 6 are located on the same side. When the first support rod 5 and the second support rod 6 rotate relative to each other, the distance between the upper frame 2 and the lower frame 3 can be changed, thereby realizing the lifting action of the lifting unit. The heater body 200 can be easily moved using the lifting base 100. When the lifting base 100 is not in operation, the first support rod 5 and the second support rod 6 rotate relative to each other to adjust the distance between the upper frame 2 and the lower frame 3 to the minimum, which facilitates the storage of the lifting base 100, reduces the space occupied by the lifting base 100, and improves the adaptability of the lifting base 100.

[0027] In other specific embodiments that can be achieved by this utility model, the connecting component can also be a hydraulic cylinder, a telescopic rod, or other structures. While connecting the upper frame 2 and the lower frame 3, it can change the relative position of the upper frame 2 and the lower frame 3 and adjust the distance between the upper frame 2 and the lower frame 3, thereby lifting and moving the heater body 200.

[0028] To ensure smooth sliding of the first support rod 5 and the second support rod 6, guide pins 7 are connected to the end of the first support rod 5 connected to the lower frame 3 and the end of the second support rod 6 connected to the upper frame 2. Both the first support rod 5 and the second support rod 6 are drive-connected to the guide pins 7. Both the upper frame 2 and the lower frame 3 have guide holes 8 that fit the guide pins 7. The guide pins 7 can slidably pass through the guide holes 8 and can rotate relative to the guide holes 8. The guide holes 8 are elongated holes. The guide pins 7 reciprocate along the length of the guide holes 8, providing guidance for the sliding movement of the first support rod 5 and the second support rod 6, ensuring the accuracy of their movement and improving the operational reliability of the lifting base 100.

[0029] Specifically, the connecting assembly also includes a support shaft 9, which is connected to one of the first support rod 5 and the second support rod 6, and is rotatably connected to the other of the first support rod 5 and the second support rod 6, so as to realize the hinged connection between the first support rod 5 and the second support rod 6.

[0030] More specifically, the lifting unit also includes a transmission assembly, which includes a transmission gear, a toothed cam 10, and a transmission rack 11. The transmission gear is connected to the support shaft 9, and the toothed cam 10 is rotatably connected to the lower frame 3. The rotation axis of the toothed cam 10 is parallel to the hinge axis of the first support rod 5 and the second support rod 6. The transmission rack 11 is slidably connected to the lower frame 3, and both the transmission gear and the transmission rack 11 mesh with the toothed cam 10. The transmission rack 11 slides relative to the lower frame 3, which can drive the meshing toothed cam 10 to rotate. The toothed cam 10 drives the meshing transmission gear to rotate, thereby driving the support shaft 9 to rotate. The support shaft 9 can drive one of the connected first support rod 5 and second support rod 6 to rotate, adjusting the distance between the upper frame 2 and the lower frame 3. The other of the first support rod and second support rod 6 also rotates adaptively to the change in the distance between the upper frame 2 and the lower frame 3, realizing the lifting action of the lifting unit. Therefore, the operator only needs to apply a force to the transmission rack 11 to make it slide back and forth, which will drive the lifting unit to move. In practical applications, the transmission gear and the support shaft 9 can be connected by a key to ensure smooth power transmission.

[0031] In this specific embodiment, the toothed cam 10 has a gear portion and a cam portion. The gear portion meshes with the transmission gear and the transmission rack 11, respectively. The cam portion abuts against one of the first support rod 5 and the second support rod 6. While ensuring smooth power transmission, the toothed cam 10 provides support for the first support rod 5 or the second support rod 6 abutting against the cam portion, thereby improving the structural stability of the lifting unit. This specific embodiment uses gear transmission to transmit force, which is precise and reliable. In other specific embodiments achievable by this utility model, other transmission methods, such as chain and sprocket transmission, can also be used to meet different working conditions and improve the adaptability of the lifting base 100.

[0032] Furthermore, the lower frame 3 has a guide groove 12 adapted to the transmission rack 11. The transmission rack 11 is slidably connected to the guide groove 12, which improves the accuracy of the reciprocating motion of the transmission rack 11 and thus improves the operational reliability of the lifting unit.

[0033] To improve the ease of operation of the lifting base 100, the lifting unit also includes a drive component. The drive component is connected to the transmission rack 11 and can drive the transmission rack 11 to slide back and forth, thereby driving the lifting base 100 to lift.

[0034] In this specific embodiment, the drive component is manually operated, requiring no maintenance and saving 100% of the operating cost of the lifting base. In this specific embodiment, the drive component uses a lever structure, reducing the workload of operators and saving time and effort.

[0035] To improve the uniformity of force distribution between the upper frame 2 and the lower frame 3, two sets of connecting components are used. The transmission components correspond one-to-one with the connecting components, and the transmission racks 11 of both sets of transmission components are connected to the drive components.

[0036] In other specific embodiments achievable by this utility model, the drive assembly includes a linkage rod 13 and an operating rod 14. The linkage rod 13 is inverted U-shaped, with its two sides connected to the transmission racks 11 of two sets of connecting assemblies, respectively. The crossbar of the linkage rod 13 is rotatably connected to the operating rod 14, and the operating rod 14 can slide relative to the linkage rod 13. The operating rod 14 is also rotatably connected to the base housing 1, allowing the operator to use the operating rod 14 to drive the linkage rod 13 to slide, thereby driving the lifting unit and achieving the lifting of the lifting unit. In practical applications, an elongated hole can be provided on the operating rod 14, allowing the operating rod 14 to rotatably connect to the linkage rod 13 and slide relative to it, thus achieving the purpose of driving the linkage rod 13 to slide. To prevent the base housing 1 from affecting the operation of the drive assembly, a notch can be provided on the side of the base housing 1 closest to the drive assembly to ensure the normal use of the linkage rod 13 and the operating rod 14. In addition, a buckle 15 can be provided on the heater body 200. The buckle 15 can be connected to the operating lever 14. When the operating lever 14 is not working, the operating lever 14 can be adjusted to be close to the heater body 200 and the operating lever 14 can be connected to the buckle 15, which facilitates the fixation of the operating lever 14, further reduces the space occupied by the lifting base 100, and improves the flexibility and adaptability of the lifting base 100.

[0037] In practical applications, the linkage rod 13 can also be pulled directly to drive the lifting unit. Alternatively, in other specific embodiments achievable with this invention, a motor drive can be used, where the motor drives the transmission gear to rotate, thereby driving the lifting unit to perform lifting actions; or a hydraulic cylinder can be used, where the hydraulic cylinder drives the transmission rack 11 to slide back and forth, which can also drive the lifting unit to achieve the lifting purpose.

[0038] Furthermore, to improve the convenience of the heater body 200, the wheels 4 can be omnidirectional wheels with brakes, which improves the movement efficiency of the pellet heater and also helps to improve the safety of transportation operations.

[0039] Example 2 This embodiment provides a pellet heater, including a heater body 200 and the aforementioned lifting base 100, wherein the heater body 200 and the base housing 1 are detachably connected.

[0040] The heater body 200 can be "lifted" using the lifting base 100, and then the heater body 200 can be moved using the walking wheels 4, which improves the ease of moving the pellet heater and reduces the workload of the operator.

[0041] The heater body 200 is detachably connected to the base housing 1, further enhancing the flexibility and adaptability of the lifting base 100. Operators can flexibly choose whether to equip the heater body 200 with the lifting base 100 based on actual usage conditions, or to achieve multi-purpose functionality for the lifting base 100, improving its adaptability and facilitating the fulfillment of various personalized needs. In practical applications, the base housing 1 and the heater body 200 can be connected by bolts, ensuring a secure connection and convenient assembly / disassembly, further improving the ease of operation of the lifting base 100.

[0042] When moving a heavy item like a pellet heater, the base shell 1 of the lifting base 100 can be connected to the pellet heater. When the pellet heater does not need to be moved, the distance between the upper frame 2 and the lower frame 3 is small, the base shell 1 is in contact with the ground, and the wheels 4 are not in contact with the ground. When the pellet heater needs to be moved, the lifting unit is activated, and the first support rod 5 and the second support rod 6 rotate relative to each other. The change in the angle between them increases the distance between the upper frame 2 and the lower frame 3, and the wheels 4 are in contact with the ground. By continuing to adjust the distance between the upper frame 2 and the lower frame 3, the base shell 1 separates from the ground, allowing the lifting base 100 to "lift" the pellet heater. After the lifting base 100 lifts the pellet heater, the heater body 200 can be easily moved using the wheels 4, improving the moving efficiency of the pellet heater and reducing the workload of the operators.

[0043] It should also be explained here that the number of traveling wheels 4 can be multiple, and the number and distribution of the traveling wheels 4 can be adjusted according to the shape and specifications of the lower frame 3 to improve the uniformity of force distribution on the lifting base 100 and improve the safety factor of the heater body 200 during movement. Correspondingly, the shape and specifications of the upper frame 2 and the lower frame 3 can be adjusted according to the shape and specifications of the heater body 200.

[0044] The lifting base 100 of this utility model has a simple and compact structure and can be easily connected to the heater body 200. When not in use, the connecting components are all located inside the base shell 1, ensuring the aesthetics of the pellet heater. When it is necessary to move the pellet heater, the lower frame 3 moves downward. After the traveling wheels 4 contact the ground, the distance between the upper frame 2 and the lower frame 3 is adjusted so that the upper frame 2 moves upward, causing the base shell 1 to detach from the ground. The pellet heater can then be easily moved by rotating the traveling wheels 4, saving time and effort, and with low operating costs.

[0045] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
