Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to a shell structure and a heater. Background Technology

[0002] 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.

[0003] Therefore, the large size of the heater causes many inconveniences in transportation. Utility Model Content

[0004] The main purpose of this utility model is to propose a shell structure and a heater, which aims to solve the problem of inconvenient transportation caused by the excessive size of the heater.

[0005] To achieve the above objectives, the present invention proposes a housing structure for use in a heater. The housing structure includes an upper housing, a lower housing, and a sliding structure. The upper and lower housings are nested together, and the inner cavities of the upper and lower housings are interconnected. The lower housing has a first through-hole, and the upper housing has a second through-hole. The sliding structure includes a groove extending in a vertical direction and a slider that slidably engages with the groove. The slider and the groove are respectively disposed between the side surfaces of the upper and lower housings, allowing the upper housing to slide vertically relative to the lower housing, having an upward position and a downward position. At least when the upper housing is in the upward position, the first and second through-holes are connected to the outside.

[0006] In one embodiment, the first through hole is located at the lower end of the lower housing, and the second through hole is located at the upper end of the upper housing; or,

[0007] The first through hole is located at the lower end of the lower housing, and the second through hole is located at the upper end of the upper housing.

[0008] In one embodiment, the housing structure further includes:

[0009] A first limiting structure is disposed between the upper housing and the lower housing to limit the upper housing when the upper housing is in the raised position.

[0010] In one embodiment, the first limiting structure includes:

[0011] A first blocking portion is provided at the upper end of the lower housing; and,

[0012] The first abutting part is provided at the lower end of the upper housing, and is used to abut against the lower side of the first blocking part when the upper housing is in the raised position, so as to restrict the upward movement of the upper housing.

[0013] In one embodiment, the first limiting structure includes:

[0014] An elastic retaining member is disposed between the upper housing and the lower housing, and is used to restrict the downward movement of the upper housing when the upper housing is in the raised position.

[0015] In one embodiment, the upper housing is sleeved around the lower housing;

[0016] An opening is provided on one side of the lower housing, and a control component is installed at the opening. The elastic retaining member is provided on the control component.

[0017] In one embodiment, the control component includes:

[0018] A mounting bracket is installed in the opening, and a resilient retaining member is respectively provided at the upper end of the mounting bracket and near both ends; and,

[0019] The operation keys are mounted on the mounting bracket.

[0020] In one embodiment, the mounting bracket has a limiting groove extending in the vertical direction, the limiting groove having an upper sidewall and a lower sidewall disposed opposite to each other in the vertical direction, and a portion of the upper housing extends into the limiting groove.

[0021] In one embodiment, the upper housing is sleeved around the lower housing;

[0022] The groove is formed on the outer side of the lower housing, and the slider is mounted on the inner side of the upper housing.

[0023] In one embodiment, both the upper housing and the lower housing are elongated in the transverse direction, having long sidewalls in the longitudinal direction and short sidewalls in the transverse direction.

[0024] The groove is formed on the long sidewall of the lower housing, and the slider is correspondingly mounted on the long sidewall of the upper housing; and / or,

[0025] The lower housing has an opening on its short side wall, and a control component is installed at the opening.

[0026] This utility model also proposes a heater, comprising a shell structure and a heating device, the heating device being disposed within the shell structure; the shell structure includes an upper shell and a lower shell, and a sliding structure, the upper shell and the lower shell being sleeved together, the inner cavities of the upper shell and the lower shell being interconnected, the lower shell having a first through hole, and the upper shell having a second through hole; and the sliding structure includes a groove extending in a vertical direction and a slider slidably engaging with the groove, the slider and the groove being disposed between the side surfaces of the upper shell and the lower shell respectively, so that the upper shell can slide vertically relative to the lower shell to have an upward position and a downward position; wherein, at least when the upper shell is in the upward position, the first through hole and the second through hole are respectively connected to the outside.

[0027] In one embodiment, the heating device is disposed within the lower housing.

[0028] The technical solution of this utility model involves a sliding connection between the upper and lower shells via a sliding structure. During its sliding stroke, the upper shell has an upward and a downward position. When the heater is working, when the upper shell slides to the upward position, most of it is misaligned with the lower shell in the vertical direction, satisfying the requirement of a large heat exchange surface area for the shell structure. When the heater is stored or transported, when the upper shell slides to the downward position, most of it overlaps with the lower shell in the vertical direction, reducing the overall volume of the shell structure. The upper and lower shells are connected by a sliding groove and a slider, allowing the slider to be installed within the groove, resulting in a smaller gap and tighter fit between the upper and lower shells, making the structure more compact and reducing the overall volume of the shell structure. This also reduces the entry of external dust and moisture into the shell structure, protecting internal components and circuitry. Because the upper shell can slide vertically and the upper and lower shells are tightly fitted, the overall volume of the heater is smaller when the upper shell is in the downward position. Therefore, the packaging volume for heating is smaller, saving packaging materials compared to existing heaters, thereby reducing packaging costs. Attached Figure Description

[0049] Existing counterbalanced heaters, in order to meet safety regulations, especially the requirements for surface temperature rise, 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, leading to higher costs during transportation and packaging, particularly during sea freight, which significantly affects container capacity. The excessive size of the heaters causes numerous inconveniences during transportation.

[0050] This utility model proposes a shell structure.

[0051] Please see Figure 1 , Figure 2 and Figure 7In one embodiment of this utility model, the housing structure 100 is used in a heater 1000. The housing structure 100 includes: an upper housing 1 and a lower housing 2, and a sliding structure. The upper housing 1 and the lower housing 2 are sleeved together. The inner cavity of the upper housing 1 and the inner cavity of the lower housing 2 are interconnected. The lower housing 2 is provided with a first through hole 22, and the upper housing 1 is provided with a second through hole 12. The sliding structure includes a groove 21 extending in the vertical direction and a slider 11 that slides with the groove 21. The slider 11 and the groove 21 are respectively disposed between the side surfaces of the upper housing 1 and the lower housing 2, so that the upper housing 1 can slide up and down relative to the lower housing 2 to have an upward position and a downward position. At least when the upper housing 1 is in the upward position, the first through hole 22 and the second through hole 12 are respectively connected to the outside.

[0052] The technical solution of this utility model involves an upper shell 1 and a lower shell 2 nested together. The upper shell 1 can be located outside the lower shell 2, or the lower shell 2 can be located outside the upper shell 1. The upper shell 1 and the lower shell 2 are slidably connected by a sliding structure. During the sliding stroke, the upper shell 1 has an upward position (see [reference]). Figure 3 ) and placement location (see below) Figure 6 When the upper shell 1 slides to the raised position, most of the upper shell 1 is misaligned with the lower shell 2 in the vertical direction. This results in a larger overall volume for both the upper and lower shells 1 and 2, and a larger heat exchange surface area for the shell structure 100, thus improving heat exchange efficiency and reducing the surface temperature of the shell, preventing it from becoming too high. Additionally, the temperature inside the shell cavity is reduced through the first through-hole 22 and the second through-hole 12. Therefore, when the upper shell 1 slides to the raised position, the heater 1000 can be activated. When the upper shell 1 slides to the lower position, most of the upper shell 1 overlaps with the lower shell 2 in the vertical direction. This reduces the overall volume occupied by the shell structure 100. During packaging, this saves packaging materials and reduces packaging costs; during transportation, the smaller size allows for increased container capacity. Therefore, sliding the upper shell 1 and lower shell 2 together ensures safety during operation while also improving transportation efficiency. The upper shell 1 and lower shell 2 are connected via a sliding groove 21 and a slider 11. Please refer to [link to relevant documentation]. Figure 10This design allows the slider 11 to be installed within the slide groove 21, achieving a sliding fit. This results in a smaller gap between the upper housing 1 and the lower housing 2, a tighter fit, a more compact structure, and a reduced overall volume of the housing structure 100. (In sliding methods using sliders and slide rails, a larger gap is required between the upper housing 1 and the lower housing 2 for the slider and slide rail to be installed.) It also reduces the entry of external dust and moisture into the housing structure 100, protecting internal components and circuits. Furthermore, a large gap between the upper housing 1 and the lower housing 2 creates a strong sense of layering between the upper and lower housings, leading to an unsightly appearance. Since the upper housing 1 has the function of sliding up and down, this design allows the upper housing 1 to be adjusted in position as needed. Simultaneously, the tight fit between the upper housing 1 and the lower housing 2 reduces the gap between them. This ingenious structural design significantly reduces the overall volume of the heater 1000 when the upper housing 1 is adjusted to the lowered position. Therefore, the required packaging volume for the heater 1000 is also reduced, significantly saving packaging materials compared to existing traditional heaters on the market. This saving not only translates to lower material costs but also reduces overall packaging costs, bringing economic benefits to businesses while also aligning with environmental protection principles.

[0053] For heaters 1000 where a heating device 200 is installed in the inner cavity of the upper housing 1 or the inner cavity of the lower housing 2, a high surface temperature of the heating device 200 can damage the device itself. Therefore, it is necessary to reduce the temperature of the heating device 200 to protect it. In one embodiment, please refer to... Figure 1 and Figure 2 The first through hole 22 is located at the lower end of the lower housing 2, and the second through hole 12 is located at the upper end of the upper housing 1; or, the first through hole 22 is located at the lower end of the lower housing 2, and the second through hole 12 is located at the upper end of the upper housing 1. This results in a significant height difference between the first through hole 22 and the second through hole 12, which is beneficial for enhancing the chimney effect and achieving cooling of the heating device 200 through a larger airflow.

[0054] To prevent the upper housing 1 from disengaging from the lower housing 2 when the upper housing 1 is pulled to slide, the housing structure 100 further includes a first limiting structure 3. The first limiting structure 3 is disposed between the upper housing 1 and the lower housing 2 to limit the upper housing 1 when it is in the raised position. This ensures that the slider 11 remains within the slide groove 21, preventing the upper housing 1 from separating from the lower housing 2.

[0055] For details, please refer to Figure 2 , Figure 7 , Figure 8 , Figure 9 The first limiting structure 3 includes a first blocking part 31 and a first abutting part 32. The first blocking part 31 is disposed at the upper end of the lower housing 2; the first abutting part 32 is disposed at the lower end of the upper housing 1, and is used to abut against the lower side of the first blocking part 31 when the upper housing 1 is in the raised position, so as to restrict the upper housing 1 from moving upward.

[0056] Considering that the upper housing 1 needs to be fixed in position when pulled to the raised position to prevent it from falling back to the lowered position under gravity, the first limiting structure 3 also includes an elastic retaining member 33. (See [link to relevant documentation]). Figure 1 , Figure 2 , Figure 11 An elastic retaining member 33 is disposed between the upper housing 1 and the lower housing 2. When the upper housing 1 is in the raised position, the elastic retaining member 33 restricts the downward movement of the upper housing 1 between the upper housing 1 and the lower housing 2. The elastic retaining member 33 can be fixedly disposed on either the upper housing 1 or the lower housing 2. When fixedly disposed on one of the upper housing 1 or the lower housing 2, the retaining member is between the upper housing 1 and the lower housing 2 and is deformed. The elastic retaining member 33 applies a spring force (i.e., pressure) to the other of the upper housing 1 and the lower housing 2, converting the spring force into a vertical frictional force to overcome the weight of the upper housing 1 and prevent it from sliding down. One or more elastic retaining members 33 can be provided. Generally, multiple elastic retaining members 33 are provided, and their installation positions are symmetrically arranged to ensure uniform force distribution and avoid sliding obstacles caused by uneven force distribution when the upper housing 1 is manually pulled. In addition, the elastic retaining member 33 can keep the upper housing 1 in any position between the raised position and the lowered position.

[0057] In one embodiment, an opening is provided on one side of the lower housing 2, and a control component 4 is installed at the opening. Utilizing the internal space of the lower housing 2, most of the control component 4 is located within the inner cavity of the lower housing 2, making the housing structure 100 more compact and reducing the overall size of the housing assembly. Please refer to... Figure 12The elastic retaining member 33 is disposed on the control component 4, extending to the area between the upper housing 1 and the lower housing 2 and abutting against the upper housing 1, generating pressure at the abutment position. Furthermore, the upper housing 1 is fitted around the lower housing 2. When the upper housing 1 slides to the raised position, the heater 1000 is in working condition. Because most of the upper housing 1 is offset from the lower housing 2 in the vertical direction, the control component 4 is exposed, facilitating adjustment of the heater 1000's settings. When the upper housing 1 is in the lowered position, the heater 1000 is in a stored or transported state. Most of the upper housing 1 overlaps with the lower housing 2 in the vertical direction, and the control component 4 is hidden inside the upper housing 1, providing protection for the control component 4.

[0058] For details, please refer to Figure 7 The control component 4 includes a mounting bracket 41 and an operation key 42. The mounting bracket 41 is mounted on the opening, and an elastic retaining member 33 is respectively provided at the upper end of the mounting bracket 41 and near both ends. To ensure a balanced distribution of the elastic force of the elastic retaining members 33 on the upper housing 1, two mounting brackets 41 can be spaced apart along the length direction, and two elastic retaining members 33 on the same mounting bracket 41 can be spaced apart along the width direction. The operation key 42 is mounted on the mounting bracket 41. The control component includes start and stop buttons, and a knob for adjusting functions.

[0059] In order to confine the upper housing 1 between the raised position and the lowered position, in an alternative embodiment, please refer to Figure 4 , Figure 5 The mounting bracket 41 has a limiting groove 411 extending in the vertical direction. The limiting groove 411 has an upper sidewall and a lower sidewall that are arranged opposite each other in the vertical direction. A portion of the upper housing 1 extends into the limiting groove 411 to limit and abut against the upper sidewall or the lower sidewall. When the portion of the upper housing 1 extending into the limiting groove 411 slides upward to abut against the upper sidewall, the upper housing 1 reaches an raised position; when it slides downward to abut against the lower sidewall, the lower housing 2 reaches a lowered position.

[0060] To minimize the gap between the upper housing 1 and the lower housing 2 and make the structure more compact, a groove 21 is recessed on one side of the housing. A slider 11 is slidably installed within the groove 21, thus reducing the distance between the upper housing 1 and the lower housing 2. The upper housing 1 is fitted around the lower housing 2; the groove 21 is formed on the outer surface of the lower housing 2, and the slider 11 is installed on the inner surface of the upper housing 1. The groove 21 is formed by the recess in the lower housing 2. When the upper housing 1 slides to its lowered position, it conceals the groove 21, making the heater 1000 more aesthetically pleasing. If the groove 21 were placed on the upper housing 1, a corresponding protrusion would form on the other side of the upper housing 1, resulting in an uneven and less aesthetically pleasing surface.

[0061] To maximize the area facing the user and improve heating efficiency while maintaining a small overall volume, the shell structure 100 is elongated. Both the upper shell 1 and the lower shell 2 are elongated laterally, each having a long sidewall in the longitudinal direction and a short sidewall in the transverse direction. Generally, since the long sidewall faces the user and is used for heating, the control component 4 is mounted on the short sidewall to avoid affecting the heating effect on the long sidewall. Therefore, the short sidewall of the lower shell 2 has an opening, at which the control component 4 is installed. However, if the control component 4 is located on only one sidewall, it would be inconvenient to also install the sliding groove 21. Therefore, the sliding groove 21 is formed on the long sidewall of the lower shell 2, and the slider 11 is correspondingly mounted on the long sidewall of the upper shell 1.

[0062] This utility model also proposes a heater 1000, which includes a heating device 200 and a shell structure 100. The heating device 200 is disposed inside 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. The housing structure 100 includes an upper housing 1, a lower housing 2, and a sliding structure. The upper housing 1 and the lower housing 2 are sleeved together, and the inner cavities of the upper housing 1 and the lower housing 2 are interconnected. The lower housing 2 is provided with a first through hole 22, and the upper housing 1 is provided with a second through hole 12. The sliding structure includes a groove 21 extending in the vertical direction and a slider 11 that slides in cooperation with the groove 21. The slider 11 and the groove 21 are respectively disposed between the side surfaces of the upper housing 1 and the lower housing 2, so that the upper housing 1 can slide vertically relative to the lower housing 2 to have an upward position and a downward position. At least when the upper housing 1 is in the upward position, the first through hole 22 and the second through hole 12 are respectively connected to the outside.

[0063] Since hot air rises, the heating device 200 needs to be located at the bottom of the shell structure 100 so that the periphery of the shell structure 100 has a heating effect. In addition, the position of the lower shell 2 is fixed, while the upper shell 1 is movable relative to the lower shell 2. Considering the stability and rationality of the installation structure, the heating device 200 is located inside the lower shell 2.

[0064] 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.
