[0068] 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 scope of protection of the present utility model.

[0069] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture.

[0071] To meet safety regulations, especially the requirements for surface temperature rise, existing counterbalanced heaters are made relatively tall to increase the heat dissipation area and thus reduce the surface temperature. This results in a larger size, especially in height, which increases the cost of transportation and packaging, particularly during sea freight, significantly affecting the container capacity.

[0072] Based on this, this utility model proposes a shell structure for a heater, aiming to solve the problem that the shell of existing heaters is too large, causing inconvenience in transportation. Among other things, Figures 1 to 27 A schematic diagram of the structure of the heater provided by this utility model.

[0073] Please see Figures 1 to 3In one embodiment of this utility model, the housing structure 100 includes a housing 1 and a limiting structure 2. The housing 1 includes an upper housing 11 and a lower housing 12 that can be nested together. The inner cavity of the upper housing 11 and / or the lower housing 12 is used to accommodate a heating element. The lower housing 12 is provided with a first through hole 12a, and the upper housing 11 is provided with a second through hole 11a. The upper housing 11 is movably mounted on the lower housing 12 in the vertical direction. During its movement, the upper housing 11 has an upward position and a downward position. The limiting structure 2 is provided between the upper housing 11 and the lower housing 12 to limit the vertical movement of the upper housing 11 when the upper housing 11 is in the upward position and / or the downward position. At least when the upper housing 11 is in the upward position, the inner cavities of the upper housing 11 and the lower housing 12 are interconnected, and the first through hole 12a and the second through hole 11a are respectively connected to the outside.

[0074] It should be noted that the shell 1 is the main load-bearing structure and needs to have a certain strength and hardness. Its material can be various, including metals such as iron or aluminum, or alloys such as steel or aluminum alloys; this invention does not limit this. Furthermore, the first through hole 12a and the second through hole 11a are used to connect with external air, allowing external air to enter and exit the shell 1 for heat exchange with the heating element inside the shell 1, thereby enabling the heater 1000 to heat the external air. The shapes of the first through hole 12a and the second through hole can be various, including circular and rectangular; this invention does not limit this. Furthermore, the location of the first through hole 12a can be various, including the bottom of the lower shell 12 or the side of the lower shell 12; this invention does not limit this. Similarly, the location of the second through hole 11a can be various, including the top of the upper shell 11 or the side of the upper shell 11; this invention does not limit this.

[0075] It should also be noted that there are multiple ways in which the upper shell 11 and the lower shell 12 can be fitted together. The upper shell 11 can be fitted inside the lower shell 12, or the lower shell 12 can be fitted inside the upper shell 11, as long as they can be fitted together. This utility model does not limit this. Furthermore, when the upper shell 11 is in the lower position, please refer to... Figures 6 to 9 The upper shell 11 and the lower shell 12 largely overlap vertically to reduce the overall height of the shell 1, significantly decreasing its overall volume. This saves packaging materials, reduces packaging costs, and facilitates transportation. When the upper shell 11 is in the raised position, please refer to... Figures 10 to 12The upper shell 11 and the lower shell 12 are offset from each other in the vertical direction to increase the overall height of the shell 1, which can significantly increase the heat exchange area of ​​the shell 1 and reduce the surface temperature of the shell 1, thereby helping to improve the heat exchange effect of the shell 1.

[0076] In the technical solution of this utility model, when the housing 1 needs to be transported, the upper housing 11 moves downward to the lower position so that the upper housing 11 and the lower housing 12 overlap vertically, thereby reducing the overall height of the housing 1 and significantly reducing its volume, thus facilitating packaging and transportation. When the housing 1 needs to dissipate heat, the upper housing 11 moves upward to the raised position so that the upper housing 11 and the lower housing 12 are misaligned vertically, thereby increasing the overall height of the housing 1 and significantly increasing its heat exchange area, reducing its surface temperature, and thus improving its heat exchange effect. In this way, through the movement of the upper housing 11, the housing 1 can both increase its height to increase its heat dissipation area and reduce its surface temperature to ensure that its heat dissipation meets safety regulations, and decrease its height to reduce its volume, making it easier to package and transport. This solves the problem that the housing 1 of the existing heater 1000 is too large, causing inconvenience in transportation.

[0077] To limit the position of the upper housing 11, please refer to... Figures 7 to 9 The limiting structure 2 includes a limiting part 21 disposed on the lower housing 12 and a mating part 22 disposed on the upper housing 11. The limiting part 21 can cooperate with the mating part 22 to limit the position. Thus, by providing the mutually cooperating limiting part 21 and the mating part 22, the upper housing 11 is limited when it is in the raised position or the lowered position, thereby positioning the upper housing 11 in the raised position or the lowered position. Further, please refer to... Figure 7 and Figure 10 Two limiting parts 21 and / or two mating parts 22 are provided. At least one limiting part 21 can be mated with the two mating parts 22 respectively for limiting. In this way, by providing two limiting parts 21 and two mating parts 22, the upper housing 11 can be positioned in both the raised position and the lower position.

[0078] For further information, please refer to [link / reference]. Figures 7 to 9In the limiting part 21 and the mating part 22, one is a positioning protrusion 211 and the other is a mating groove 221. Thus, the engagement of the positioning protrusion 211 and the mating groove 221 limits the movement of the upper housing 11, thereby allowing the upper housing 11 to be positioned on the lower housing 12. It is understood that the limiting part 21 and the mating part 22 can be either the limiting part 21 being the positioning protrusion 211 and the mating part 22 being the mating groove 221, or the limiting part 21 being the mating groove 221 and the mating part 22 being the positioning protrusion 211. This invention does not limit the specific configuration.

[0079] The limiting part 21 can be configured in various ways. It can be fixedly disposed on the lower housing 12 or movably disposed on the lower housing 12. This invention does not limit the specific configuration. Specifically, in this embodiment, please refer to... Figure 8 and Figure 9 The limiting part 21 or the mating part 22 is elastically movable in the horizontal direction. Thus, through the elastic movement of the limiting part 21 or the mating part 22, the limiting part 21 can engage with the mating part 22 to limit the movement of the upper housing 11, allowing the upper housing 11 to be positioned on the lower housing 12. At the same time, the limiting part 21 can separate from the mating part 22 to release the limitation on the upper housing 11, allowing the upper housing 11 to move in the vertical direction.

[0080] It should be noted that the horizontally elastically movable arrangement of the limiting part 21 or the mating part 22 means that either the limiting part 21 or the mating part 22 can be elastically movable in the horizontal direction; this utility model does not limit this. Furthermore, "elastically movable" means that the limiting part 21 or the mating part 22 can move through its own elastic deformation or through the driving force of an elastic element; this utility model does not limit this either.

[0081] It should also be noted that the above two related technical features: "one of the limiting part 21 and the mating part 22 is a positioning protrusion 211 and the other is a mating groove 221" and "the limiting part 21 or the mating part 22 is elastically movable in the horizontal direction" can be selected or can be set at the same time. This utility model does not limit this.

[0082] In some embodiments, please refer to Figure 9 and Figure 12The limiting part 21 is configured as the positioning protrusion 211, and correspondingly, the mating part 22 is configured as the mating groove 221. The upper housing 11 is provided with a sliding groove 111 extending in the vertical direction, and the mating groove 221 is provided in the sliding groove 111. In this way, by setting the sliding groove 111, the horizontal movement of the positioning protrusion 211 is restricted, so that the positioning protrusion 211 can move in the vertical direction. This facilitates the sliding of the positioning protrusion 211 and allows the positioning protrusion 211 to slide smoothly into the mating groove 221, thereby ensuring the limiting effect of the limiting structure 2 and helping to improve the stability of the limiting structure 2.

[0083] If the limiting part 21 or the mating part 22 moves through its own elastic deformation, after prolonged use, the limiting part 21 or the mating part 22 may not rebound sufficiently, causing the limiting to fail. Based on this, please refer to... Figure 8 and Figure 9 The limiting structure 2 further includes a reset member 23 disposed on the lower housing 12, which is used to reset the limiting part 21 to a position where it can engage with the mating part 22 for limiting. Thus, by providing the reset member 23, the limiting part 21 or the mating part 22 can be driven to interact, allowing the limiting part 21 to engage with the mating part 22 for limiting. This enables the limiting part 21 or the mating part 22 to be made of a higher strength material, reducing the risk of failure of the limiting structure 2 and thus helping to extend the service life of the limiting structure 2.

[0084] In one embodiment of this utility model, please refer to Figure 4 and Figure 14 The housing structure 100 further includes a guide structure 3, which includes a guide rod 31 and a guide hole 32 that cooperate to guide each other. One of the guide rod 31 and the guide hole 32 is located in the upper housing 11, and the other is located in the lower housing 12. Thus, by providing the guide rod 31 and the guide hole 32, the horizontal movement of the upper housing 11 is restricted, allowing the upper housing 11 to move vertically, thereby improving the stability of the upper housing 11's movement. Furthermore, two guide structures 3 are provided, spaced apart at both ends of the housing 1. Thus, by providing two guide structures 3, the movement of both ends of the upper housing 11 is guided, allowing both ends of the upper housing 11 to move smoothly vertically, thereby improving the stability of the upper housing 11's movement.

[0085] Further, please refer to Figure 19 and Figure 20The limiting structure 2 is disposed between the guide rod 31 and the guide hole 32, thereby integrating the limiting structure 2 and the guide structure 3 together, which helps to improve the space utilization of the housing 1.

[0086] In one embodiment of this utility model, please refer to Figure 4 and Figure 14 The lower housing 12 includes a lower housing body 121 and a mounting member 122 disposed on the lower housing body 121. The limiting structure 2 is disposed between the mounting member 122 and the upper housing 11. Thus, by setting the lower housing body 121 and the mounting member 122 separately for molding, the molding difficulty of the lower housing 12 is reduced. Furthermore, there are various ways to connect the mounting member 122 and the lower housing body 121. The mounting member 122 can be welded to the lower housing body 121 or screwed to the lower housing body 121, etc., as long as it can fix the mounting member 122 to the lower housing body 121. This utility model does not limit this.

[0087] Further, please refer to Figures 14 to 16 The mounting component 122 includes two mounting parts, each of which has a guide groove extending vertically. The two mounting parts are joined together so that the two guide grooves are joined to form the guide hole 32, which facilitates the assembly of the limiting structure 2. Furthermore, the two mounting parts can be connected in various ways, such as by screws or by snap-fit ​​connections, etc., and this utility model does not limit this method.

[0088] In one embodiment of this utility model, please refer to Figures 3 to 5 The housing structure 100 further includes a guide structure 3. The mounting component 122 includes a mounting body 1221 and a mounting part 1222 detachably mounted on the mounting body 1221. The limiting structure 2 is located between the mounting part 1222 and the upper housing 11, and the guide structure 3 is located between the mounting body 1221 and the upper housing 11. Thus, by setting the mounting body 1221 and the mounting part 1222, the limiting structure 2 and the guide structure 3 are respectively set, so that the guide structure 3 is separated from the limiting structure 2, so as to prevent the limiting structure 2 and the guide structure 3 from affecting each other, thereby helping to improve the reliability of the housing 1.

[0089] In one embodiment of this utility model, please refer to Figure 7Two limiting structures 2 are provided, and the two limiting structures 2 are respectively provided at both ends of the length direction of the housing 1. In this way, by providing two limiting structures 2, the two ends of the upper housing 11 are limited, which can improve the limiting effect and share the weight of the upper housing 11, reducing the load of a single limiting structure 2, thereby helping to extend the service life of the limiting structure 2.

[0090] In one embodiment of this utility model, please refer to Figure 5 and Figure 15 A plurality of rollers 4 are provided between the upper housing 11 and the lower housing 12. The plurality of rollers 4 are arranged at intervals along the circumference of the housing 1. In this way, by providing a plurality of rollers 4, rolling friction is formed between the upper housing 11 and the lower housing 12, so as to reduce the friction force of the upper housing 11 and make the movement of the upper housing 11 smoother.

[0091] In order to position the upper housing 11 in the lower position, in this embodiment, please refer to... Figure 17 and Figure 18 The upper housing 11 is provided with a stop 24 to abut against the upper end face of the lower housing 12. Thus, by providing the stop 24 so that the upper end face of the lower housing 12 abuts against it, the upper housing 11 can be positioned in the lower position.

[0092] In one embodiment of this utility model, please refer to Figure 13 An operating lever 5 is provided on the outside of the housing 1. Thus, by setting the operating lever 5, on the one hand, it is convenient for personnel to operate the upper housing 11, and on the other hand, it can also be used to support items, so that the heater 1000 can be used to dry items.

[0093] Please refer to the figure in one embodiment of this utility model. Figure 21 , Figure 25 and Figure 26 The upper housing 11 is provided with an upper barb 112 at its lower end, and the lower housing 12 is provided with a lower barb 123 at its upper end. When in the raised position, the upper barb 112 and the lower barb 123 engage to hook together, so that when the upper housing 11 is in the raised position, the upper barb 112 and the lower barb 123 can fit together, making the side connection between the upper housing 11 and the lower housing 12 more secure, thereby making the structure of the entire housing 11 more reliable.

[0094] In some embodiments, please refer to Figure 21 and Figure 22An anti-slip part 6 is provided between the upper housing 11 and the lower housing 12. The anti-slip part 6 extends in the vertical direction. In this way, by providing the anti-slip part 6, the friction between the upper housing 11 and the lower housing 12 is increased, so as to prevent the housing 1 from being damaged due to the upper housing 11 sliding too fast.

[0095] It is understood that the anti-slip part 6 may be provided on the upper housing 11, or on the lower housing 12, or on both the upper housing 11 and the lower housing. This utility model does not limit this.

[0096] In one embodiment of this utility model, please refer to Figure 22 The lower housing 12 is provided with reinforcing plates 7. By providing the reinforcing plates 7, the two opposite sidewalls of the lower housing 12 are supported, thereby strengthening the lower housing 12 and reducing the risk of deformation. Furthermore, multiple reinforcing plates 7 are provided, spaced apart on the lower housing 12, to further increase the strength of the lower housing 12.

[0097] In one embodiment of this utility model, please refer to Figure 23 and Figure 24 An elastic connection structure 8 is provided between the upper housing 11 and the lower housing 12. By providing this elastic connection structure 8, when the upper housing 11 moves to the raised position, it is positioned on the lower housing 12, thereby maintaining the upper housing 11 in the raised position. Furthermore, the elastic connection structure 8 includes a hook 81 and a spring hook 82, one of which is located on the upper housing 11 and the other on the lower housing 12. Thus, the cooperation of the hook 81 and the spring hook 82 limits the movement of the upper housing 11, thereby positioning the upper housing 11 on the lower housing 12.

[0098] It should be noted that the above three related technical features: "an anti-slip part 6 is provided between the upper shell 11 and the lower shell 12", "a reinforcing plate 7 is provided on the lower shell 12", and "an elastic connection structure is provided between the upper shell 11 and the lower shell 12" can be provided in one, two, or simultaneously. This utility model does not limit the specific features in this regard.

[0099] In one embodiment of this utility model, please refer to Figure 22 and Figure 27 The lower housing 12 is provided with a receiving groove 124 for installing the anti-slip part 6. In this way, by providing the receiving groove 124, the thickness of the lower housing 12 can be reused, thereby helping to make the housing 1 more compact.

[0100] In some embodiments, please continue reading Figure 22 Multiple anti-slip parts 6 are provided, and the multiple anti-slip parts 6 are arranged circumferentially along the upper shell 11 or the lower shell 12 to keep the friction between the upper shell 11 and the lower shell 12 balanced, thereby making the upper shell 11 slide more smoothly.

[0101] The anti-slip part 6 can be made of various materials. Specifically, in this embodiment, the anti-slip part 6 is made of plastic or rubber, which can both increase the friction between the upper shell 11 and the lower shell 12 and prevent the shell from being scratched. It is understood that the material of the anti-slip part 6 includes plastic or rubber, meaning that the anti-slip part 6 can be a plastic anti-slip part or a rubber anti-slip part, and this utility model does not limit it in this way.

[0102] It should be noted that the above three related technical features: "the lower housing 12 is provided with a receiving groove 124", "the anti-slip part 6 is provided in multiple ways", and "the material of the anti-slip part 6 includes plastic or rubber", can be selected to be provided, two of them can be provided, or they can be provided at the same time. This utility model does not limit this.

[0103] In one embodiment of this utility model, the lower housing 12 is elongated in the transverse direction, and the reinforcing plate 7 is provided between the two ends of the lower housing 12 in the width direction. Since the two sides of the lower housing 12 are relatively large in the width direction, they are easily deformed by external impact. Therefore, in this embodiment, by providing the reinforcing plate 7 between the two ends of the lower housing 12 in the width direction, the strength of the lower housing 12 can be improved, thereby reducing the risk of deformation of the lower housing 12.

[0104] This utility model also proposes a heater 1000, which includes a heating element 200 and a shell structure 100. The heating element 200 is disposed in the shell structure 100. The specific structure of the shell structure 100 is as described in the above embodiments. Since this heater 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0105] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
