As used in the utility model embodiment specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0034] See also Figure 1-Figure 9 The embodiment of the utility model proposes a detachable bottom support frame, the chassis 10 and the support legs 20 of the detachable bottom support frame are detachable, so as to facilitate storage and reduce the packaging volume. At the same time, after the chassis 10 and the support legs 20 are assembled, the structure is stable and the reliability is high. In order to achieve the above technical purpose, the detachable bottom support frame includes a chassis 10 and a support leg 20, and the specific structure is described as follows:

[0035] The bottom side of the chassis 10 is provided with a mounting opening 11 , and the inner side surface of the mounting opening 11 is provided with a first protruding clamping portion 12 , that is, the first clamping portion 12 protrudes outward from the inner side surface of the mounting opening 11 , so as to facilitate clamping and limiting.

[0036] A mounting head 21 is provided at one end of the support leg 20, and the mounting head 21 is mounted corresponding to the mounting opening 11. A clamping unit 22 is provided on the outer side of the mounting head 21, and the clamping unit 22 includes a clearance groove 221 and a second clamping portion 222 provided on one side of the clearance groove 221. The clearance groove 221 is formed by a depression on the outer surface of the mounting head 21, and the second clamping portion 222 is protruding outward compared to the bottom of the clearance groove 221. The second clamping portion 222 can be a part of the mounting head 21.

[0037] In the utility model, after aligning the air avoidance groove 221 of the mounting head 21 with the first clamping portion 12 of the mounting opening 11, the mounting head 21 is inserted into the mounting opening 11; then the mounting head 21 is rotated in a direction that brings the first clamping portion 12 and the second clamping portion 222 closer together (clockwise rotation in this embodiment), so that the first clamping portion 12 and the second clamping portion 222 can be detachably engaged, thereby achieving clamping fixation; reverse rotation can achieve disassembly.

[0038] Furthermore, the mounting opening 11 and the mounting head 21 are both circular, so as to facilitate rotational fit.

[0039] By applying the technical solution of the embodiment of the utility model, the detachable bottom support frame includes a chassis 10 and a supporting foot 20, the bottom side of the chassis 10 is provided with a mounting port 11, the inner side surface of the mounting port 11 is provided with a first protruding clamping portion 12; one end of the supporting foot 20 is provided with a mounting head 21, the outer side surface of the mounting head 21 is provided with a clamping unit 22, the clamping unit 22 includes a void groove 221 and a second clamping portion 222 arranged on one side of the void groove 221, after aligning the void groove 221 of the mounting head 21 with the first clamping portion 12 of the mounting port 11, the mounting head 21 is inserted into the mounting port 11; then the mounting head 21 is rotated in a direction that brings the first clamping portion 12 and the second clamping portion 222 closer to each other, so that the first clamping portion 12 and the second clamping portion 222 can be detachably engaged, and disassembly can be achieved by reverse rotation. It can be seen that the chassis 10 and the supporting legs 20 of the detachable bottom support frame are detachable, so as to facilitate storage and reduce the packaging volume. At the same time, after the chassis 10 and the supporting legs 20 are assembled, the structure is stable and the reliability is high.

[0040] Further, in some embodiments, such as the present embodiment, the first clamping portion 12 is a boss protruding outward from the inner side of the mounting opening 11, and the boss is provided with a clamping groove 121. The clamping groove 121 can be specifically located on the lower side of the boss, and the number of the clamping grooves 121 can be one or more, which is not specifically limited by the present invention.

[0041] Correspondingly, the second clamping portion 222 is a convex block provided at one side of the avoidance groove 221 and protruding outward relative to the bottom of the avoidance groove 221, and the convex block is provided with a clamping tooth 2221 corresponding to the clamping groove 121. The convex block may be a part of the side wall of the mounting head 21. The clamping tooth 2221 may be specifically located on the lower side of the convex block. The number of the clamping teeth 2221 is the same as that of the clamping groove 121, which may be one or more, and the utility model does not specifically limit this.

[0042] During installation, the first clamping portion 12 slides along the avoidance groove 221 to the lower side of the second clamping portion 222 . After rotation, the first clamping portion 12 is clamped into the lower part of the second clamping portion 222 . At this time, the clamping teeth 2221 are correspondingly clamped into the clamping groove 121 .

[0043] Further, the outer side surface of the mounting head 21 is provided with a receiving area 223 located on one side of the protrusion, and the receiving area 223 is used to receive the boss. The receiving area 223 is recessed compared to the outer side surface of the mounting head 21, and the receiving area 223 can be specifically a receiving hole or a receiving groove. For example, in this embodiment, the receiving area 223 is a receiving hole. In order to save materials, the mounting head 21 is provided with a center hole, and the receiving area 223 is a receiving hole that penetrates the side wall of the mounting head 21.

[0044] Furthermore, the avoidance groove 221 starts from the end face of the mounting head 21, and the width of the avoidance groove 221 is equal to the sum of the width of the boss and the width of the bump. Thus, on the one hand, the avoidance groove 221 starts from the end face of the mounting head 21, which facilitates the boss to enter the avoidance groove 221, and on the other hand, the width of the avoidance groove 221 is equal to the sum of the width of the boss and the width of the bump, so that the boss and the bump can be tightly limited to avoid looseness.

[0045] Further, the number of the engaging units 22 is the same as the number of the first engaging portions 12, and both are multiple; multiple engaging units 22 are evenly arranged on the outer side of the mounting head 21; multiple first engaging portions 12 are evenly arranged on the inner side of the mounting opening 11. For example, in this embodiment, the number of the engaging units 22 and the number of the first engaging portions 12 are both two. By providing multiple engaging units 22 corresponding to each other one by one and engaging with multiple first engaging portions 12, the stability of the connection between the support foot 20 and the chassis 10 can be greatly improved.

[0046] Further, a support plate 13 is provided in the mounting opening 11, and the upper end surface of the mounting head 21 abuts against the support plate 13. The support plate 13 is connected to the bottom plate of the chassis 10, for example, the support plate 13 can be integrally formed with the bottom plate of the chassis 10. The upper end surface of the mounting head 21 abuts against the support plate 13, thereby achieving reliable support.

[0047] Further, the number of the supporting legs 20 is the same as the number of the mounting openings 11, and both are greater than or equal to 3. The mounting openings 11 are evenly arranged on the bottom side of the chassis 10, and multiple supporting legs 20 are correspondingly installed in multiple mounting openings 11. For example, in this embodiment, the number of the supporting legs 20 is 4. The number of the supporting legs 20 is greater than or equal to 3, so that reliable support can be achieved.

[0048] An embodiment of the utility model provides a heater, which includes a heater body 30 and the detachable bottom support frame provided in any of the above embodiments, wherein the detachable bottom support frame is used to support the heater body 30 .

[0049] Specifically, the chassis 10 of the detachable bottom support frame is provided with a mounting groove 14, and the bottom of the heater body 30 is detachably embedded in the mounting groove 14. The bottom of the heater body 30 can be connected to the chassis 10 by fasteners and / or a buckle structure, which is not specifically limited in comparison with the embodiment of the utility model.
