Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating equipment technology, and in particular to a small portable heater. Background Technology
[0002] Common types of heaters include ceiling-mounted, floor-standing, and wall-mounted types. Floor-standing heaters include large and small models. Small floor-standing heaters are flexible in use, easy to carry, and convenient to use in different locations.
[0003] Existing portable floor heaters come in a wide variety of styles. For example, CN221881598U discloses a portable heater with a convenient overall structure that is easy to assemble and carry. Another example is CN219177804U, which discloses an automatic temperature-controlled desktop heater that is also portable and compact. Yet another example is CN22132457U, which discloses a desktop heater. While these small and portable heaters are all convenient to carry, they all neglect the issue of different users having different viewing angles.
[0004] Specifically, regardless of whether a small heater is placed directly on the floor or used on a table, different users have different heights and usage preferences, meaning their requirements for the angle of heat radiation vary. Therefore, heaters with a fixed heat radiation angle lack flexibility in use. Consequently, for small and portable heaters, further structural optimization is needed to improve their flexibility of use. Utility Model Content
[0005] The purpose of this invention is to provide a small, portable heater to solve the technical problem of improving the flexibility of its use.
[0006] The small portable heater of this utility model is implemented as follows:
[0007] A small portable heater includes:
[0008] The outer casing includes a main housing for forming a recessed receiving cavity and side plates detachably connected to a pair of opposing side faces of the main housing; one side of the main housing is formed with an opening communicating with the receiving cavity and adapted for heat radiation.
[0009] A thermal radiation assembly, comprising a reflector and an electric heating device disposed within a containment cavity and used in conjunction therewith;
[0010] A support leg assembly includes a pair of support legs detachably coupled to a pair of side plates; each support leg is rotatably coupled to a side plate, and each support leg is also coupled with a fastener adapted to pass through the support leg and lock into the side plate; the fastener has a limiting portion formed on it adapted to press the support leg against the side plate.

[0014] The folded plates of the pair of support legs are bent in opposite directions relative to the clamping plate, and the end faces of the folded plates of the pair of support legs facing away from the heat radiation assembly are on the same horizontal plane to form bottom support for the outer shell and the heat radiation assembly.
[0015] In optional embodiments of this utility model, both the clamping plate and the folding plate are made of thin, flat metal parts, and the clamping plate and the folding plate are integrally formed; and
[0016] The clamping plate is adapted to fit tightly against the side plate, and the folding plate is perpendicular to the clamping plate.
[0017] In an optional embodiment of this utility model, the clamping plate is provided with a through hole suitable for the long screw to pass through, and the through hole is rotatably engaged with the long screw.

Detailed Implementation
[0031] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0032] Example 1:
[0033] Please see Figures 1 to 5 As shown, this embodiment provides a small portable heater, including: an outer shell, a heat radiation component disposed inside the outer shell, and a support leg assembly that is mated and connected to the outer shell.
[0034] Specifically, the first part is the outer casing, which includes a main housing 11 for forming a concave receiving cavity and side plates 12 detachably connected to a pair of opposite side faces of the main housing 11; one side of the main housing 11 has an open opening that communicates with the receiving cavity and is suitable for heat radiation; here, with reference to the accompanying drawings, the example is that the open opening is rectangular, then the pair of side plates 12 are located at a pair of width-direction side ends of the open opening, so that the entire heater radiates light laterally, increasing its light-emitting area in the lateral dimension, which can be used for, for example but not limited to, desktop use.
[0035] Secondly, the thermal radiation assembly includes a reflector and an electric heating device 3 housed within a receiving cavity and used in conjunction with each other. The reflector contains a lamp holder 4 for fixing the electric heating device 3. The lamp holder 4, reflector, and outer casing are connected by connectors. A pair of connecting ears 41 are pre-set on the lamp holder 4 for mounting and fixing the electric heating device 3. These connectors can be, for example, but are not limited to, screws. After the electric heater is fixed to the lamp holder 4, the lamp holder 4, reflector, and outer casing together achieve a secure fit. This structure simplifies the structure and assembly process.
[0036] Based on the above structure, it should also be noted that the reflector includes a main body 21 for forming a concave receiving cavity and a pair of side wing plates 22 that are detachably engaged with a pair of opposing side end faces of the main body 21; the side wing plates 22 are provided with through holes through which the wiring terminal 31 of the electric heater passes. It should be noted that a lateral gap is formed between the side plate 12 and the side wing plates 22, so that a lateral cavity is formed between them to accommodate the wiring terminal 31 of the electric heater, and the opening of the main housing 11 extends into this lateral cavity.
[0037] To protect the electric heater, the heat radiation assembly also includes a protective cover 7 located at the open end and connected to the reflector for protecting the electric heating device 3. In one optional embodiment, the protective cover 7 is made of steel wire, and each side wing plate 22 has at least one mating hole 221 for engaging the protective cover 7, and the protective cover 7 is formed with multiple snap-fit connectors 71 suitable for one-to-one engagement into the mating holes 221. That is, the main body 21 is directly connected to the lamp holder body 4, while the side wing plate 22 is simultaneously fastened to the protective cover 7 during the assembly process with the main body 21. For the transverse cavity, protection can be achieved using the protective cover 7, i.e., the protective cover 7 can be fixed to the side plate 12, or a baffle 8 can be configured separately. In this case, a slot for inserting the baffle 8 can be provided on the edge of the cavity opening corresponding to the transverse cavity, so that the baffle 8 can be inserted into the transverse cavity from the opening of the outer shell connecting to the side plate 12, which is also easy to assemble.
[0038] Finally, the support leg assembly should be described, which includes a pair of support legs detachably coupled to a pair of side plates 12; each support leg is rotatably coupled to the side plate 12, and each support leg is also fitted with a fastener suitable for locking into the side plate 12 after passing through the support leg; the fastener has a limiting part formed on it suitable for pressing the support leg against the side plate 12. It should be noted here that when the small portable heater of this embodiment is placed on a table, under the support of the pair of support legs, the bottom end surfaces of the pair of support legs will directly contact the table, while the bottom end surface of the outer shell will not contact the table, so that a certain longitudinal distance is formed between the bottom end surface of the outer shell and the table. Thus, by adjusting the engagement angle between the support legs and the side plate 12, the angle between the opening of the outer shell and the table, that is, the heat radiation angle, can be adjusted.
[0039] Based on the above structure, and referring to the accompanying drawings, in one optional case, the fastener is a long screw 51; and the long screw 51 is provided with a knob 52 for rotating the long screw 51, with the limiting part being the end face of the knob 52 facing the side plate 12, and the long screw 51 forming a threaded engagement with the side plate 12. Based on this, by manually turning the knob 52, the long screw 51 is screwed out a certain distance relative to the side plate 12, so that the knob 52 does not exert a squeezing effect on the support leg, and the support angle of the support leg relative to the side plate 12 can be adjusted. After adjustment, the knob 52 is manually turned again, so that the long screw 51 is screwed in relative to the side plate 12 until the knob 52 and the side plate 12 engage to squeeze the sides of the support leg, and the engagement angle of the support leg relative to the side plate 12 is fixed.
[0040] Based on the above structure, and referring to the accompanying drawings, in an optional embodiment, each support leg includes a clamping plate 61 suitable for being clamped between the limiting part and the side plate 12, and a folding plate 62 bent and connected to the end of the clamping plate 61 away from the fastener; and the bending directions of the folding plates 62 of the pair of support legs are opposite to those of the clamping plate 61, and the end faces of the folding plates 62 of the pair of support legs facing away from the heat radiation assembly are on the same horizontal plane, thereby forming bottom support for the outer shell and the heat radiation assembly. Based on this, in an optional embodiment, both the clamping plate 61 and the folding plate 62 are made of thin, flat metal parts, resulting in low material costs, and the clamping plate 61 and the folding plate 62 are integrally formed, making them easy to process; and the folding plate 62 is perpendicular to the clamping plate 61, while the clamping plate 61, after being clamped and fixed by the limiting part and the side plate 12, is tightly attached to the side plate 12, thereby increasing the contact area between the clamping plate 61 and the side plate 12 and improving the overall stability of the heater during use. The clamping plate 61 has a through hole suitable for the long screw 51 to pass through, and the through hole is rotatably engaged with the long screw 51. The pair of supporting legs of this structure, together with the outer shell, make the overall small portable heater roughly "lizard" shaped, which can increase its appearance and fun.
[0041] In summary, for the small portable heater of this embodiment, by using the rotating engagement of the support legs and side plate 12, the angle of the open end of the small portable heater relative to the table or ground can be adjusted by changing the engagement angle between the support legs and side plate 12, thus adjusting the radiation angle of the heater's heat source and meeting the needs of different users. During this process, adjusting the support legs relative to the side plate 12 only requires switching between loosening and tightening the fasteners, making the adjustment process convenient and efficient. Furthermore, the pair of support legs together support the entire heater, satisfying both angle adjustment and support requirements, and eliminating the need for other support structures, thus simplifying the structure.
