DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0038] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, reference numerals and / or letters can be repeated in different examples in the present application. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0039] For the convenience of description, spatial relative terms can be used in the specification to describe the relative position relationship or movement condition of one element or feature relative to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientations depicted in the drawings. For example, if the device in the drawings is turned over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "over" another element or feature. Therefore, the example term "below" can include both upward and downward positions. The device can be additionally oriented (rotated by 90 degrees or in other directions) and the spatial relative relationship descriptors used in the specification are interpreted accordingly.

[0040] In the prior art, the manual cold / warm air conversion electric heater usually adopts a single-layer spring structure to realize the positioning of the switch handle.

[0041] However, the clamping force of the single-layer spring is limited and cannot firmly fix the switch handle. When the device is working, if it is subjected to external impact or vibration, the switch handle is easy to loosen from the spring clamping slot, and loosening is easy to cause abnormal sensing of the micro switch, which may cause the whole machine to be powered off or the function switching error, affecting the normal use experience of the user.

[0042] To solve the technical problem that the prior art uses a single-layer spring structure to realize the positioning of the switch handle, resulting in the inability to firmly fix the switch handle, the present application provides a cold / warm fan, which can improve the stability of the handle and prevent the handle from loosening.

[0043] Referring to Figures 1-9 The cold / warm fan 10 provided by the present application comprises a fan body 100, a heating element 200, a micro switch 300 and a double-layer elastic clamping piece.

[0044] The fan body 100 has a first position 101 and a second position 102; the heating element 200 is provided with a handle 210, and the heating element 200 is slidably connected to the fan body 100, so that the handle 210 can be selectively in the first position 101 or the second position 102.

[0045] The number of micro switches 300 and double-layer elastic clamping pieces can be multiple, and the first position 101 and the second position 102 are each provided with the micro switch 300; the first position 101 and the second position 102 are each provided with the double-layer elastic clamping piece.

[0046] Among them, multiple micro switches 300 can include a first micro switch 310 and a second micro switch 320, for example, the handle 210 triggers the micro switch 300 located at the first position 101 can be a first micro switch 310, and the handle 210 triggers the micro switch 300 located at the second position 102 can be a second micro switch 320.

[0047] Similarly, multiple double-layer elastic clamping pieces can include a first double-layer elastic clamping piece 410 and a second double-layer elastic clamping piece 420, wherein the double-layer elastic clamping piece located at the first position 101 can be a first double-layer elastic clamping piece 410, and the double-layer elastic clamping piece located at the second position 102 can be a second double-layer elastic clamping piece 420.

[0048] Specifically, when the handle 210 is at the first position 101, the handle 210 triggers the micro switch 300 located at the first position 101, and the double-layer elastic clamping piece located at the first position 101 elastically clamps the handle 210; when the handle 210 is at the second position 102, the handle 210 triggers the micro switch 300 located at the second position 102, and the double-layer elastic clamping piece located at the second position 102 elastically clamps the handle 210.

[0049] The cold and warm fan 10 provided by the embodiment, by adopting multiple double-layer elastic clamping pieces, such as the double-layer elastic clamping piece provided at the first position 101 and the second position 102, based on this, when the handle 210 is at the first position 101, the handle 210 triggers the micro switch 300 located at the first position 101, and the double-layer elastic clamping piece located at the first position 101 elastically clamps the handle 210; when the handle 210 is at the second position 102, the handle 210 triggers the micro switch 300 located at the second position 102, and the double-layer elastic clamping piece located at the second position 102 elastically clamps the handle 210. Because the double-layer elastic clamping piece has stronger clamping force, it can more firmly fix the handle 210. Even if the whole machine is working and is subjected to external impact or vibration, the handle 210 is not easy to loosen, that is, the stability of the handle 210 can be improved.

[0050] In addition, since the double-layer elastic clamping member disperses the force, the elastic force required for the elastic sheet is relatively small, and thus the user needs less force when manually moving the handle 210, and the operation is more comfortable.

[0051] In some embodiments, the first double-layer elastic clamping member 410 and the second double-layer elastic clamping member 420 can be installed in the corresponding positions of the fan body 100 by riveting, welding, buckle connection, or screw connection.

[0052] In some embodiments, the material of the first double-layer elastic clamping member 410 and the second double-layer elastic clamping member 420 can be plastic or spring steel sheet, etc.

[0053] In some embodiments, the double-layer elastic clamping member includes a first elastic sheet 411 and a second elastic sheet 412, which jointly enclose an elastic limiting space 413, and the elastic limiting space 413 has an opening 414 for the handle 210 to be placed in the elastic limiting space 413 along the sliding path of the heating element 200.

[0054] In this way, the first elastic sheet 411 and the second elastic sheet 412 jointly enclose the elastic limiting space 413, and when the handle 210 performs cold or warm air work, the handle 210 is placed in the elastic limiting space 413 along the sliding path of the heating element 200, and the elastic limiting space 413 can effectively fix the heating element 200, preventing the whole machine from being touched during work, causing the micro switch 300 to sense abnormally, and thus causing the whole machine to be powered off.

[0055] Among them, the first elastic sheet 411 and the second elastic sheet 412 jointly act to form a double clamping effect, significantly improving the stability of the handle 210. Even if the whole machine is subjected to external impact or vibration, the handle 210 is not easy to loosen.

[0056] In some embodiments, the first elastic sheet 411 and the second elastic sheet 412 can be integrally formed to form a whole structure.

[0057] Alternatively, in other embodiments, the first elastic sheet 411 and the second elastic sheet 412 are independently manufactured and then assembled together by some means (such as riveting, welding, buckling, or bonding) to jointly form the elastic limiting space 413.

[0058] In some embodiments, when the handle 210 is located in the elastic limiting space 413, the first elastic sheet 411 and the second elastic sheet 412 are respectively located on the opposite sides of the handle 210.

[0059] In some embodiments, the first elastic sheet 411 is provided with a first stop protrusion 415 on one side facing the second elastic sheet 412, and the second elastic sheet 412 is provided with a second stop protrusion 416 on one side facing the first elastic sheet 411, and the first stop protrusion 415 and the second stop protrusion 416 cooperate to limit the handle 210 from the opening 414.

[0060] In some embodiments, the fan body 100 comprises a mounting frame 500, and the heat generating member 200 is slidably connected to the mounting frame 500, and the mounting frame 500 is provided with a guide passage 510, the guide passage 510 extends through the opposite sides of the mounting frame 500 along the sliding path of the heat generating member 200, and the handle 210 is arranged in the guide passage 510.

[0061] In this way, the guide passage provides a clear path for the sliding of the handle 210 and the heat generating member 200, ensuring that they can only move in a predetermined direction, i.e. along the guide passage, avoiding deviation or jamming.

[0062] In addition, when the handle 210 slides in the guide passage, it can always maintain a stable motion trajectory, thereby improving the consistency and reliability of user operation.

[0063] In some embodiments, the handle 210 comprises a handle portion 211 and a pressing portion 212 connected together, the handle portion 211 and the pressing portion 212 are located on opposite sides of the heat generating member 200, and the handle portion 211 is arranged in the guide passage 510.

[0064] Participate Figures 4-6 When the handle 210 is in the first position 101, the pressing portion 212 triggers the micro switch 300 located in the first position 101, and the double-layer elastic clamping member located in the first position 101 elastically clamps the handle portion 211; when the handle 210 is in the second position 102, the pressing portion 212 triggers the micro switch 300 located in the second position 102, and the double-layer elastic clamping member located in the second position 102 elastically clamps the handle portion 211.

[0065] In this way, the micro switch 300 is placed directly below the pressing portion 212 of the handle 210, and when the pressing portion 212 of the handle 210 presses on the switch key of the micro switch 300, even if the pressing portion 212 of the handle 210 shakes slightly, it will not affect the tripping of the micro switch 300, thereby improving the stability of the micro switch 300.

[0066] In some embodiments, the fan body 100 comprises a mounting frame 500, the heating element 200 is slidably connected to the mounting frame 500, the mounting frame 500 has a first side 520 and a second side 530 arranged oppositely, a plurality of the micro switches 300 are located on the first side 520, and a plurality of the double-layer elastic clamping members are located on the second side 530.

[0067] In this way, by arranging the micro switches 300 and the double-layer elastic clamping members on the two sides of the mounting frame 500 respectively, the limited space resources can be fully utilized, the overall structure of the cooling and heating fan 10 is more compact, and the cross interference between the components can be reduced, thereby improving the reliability of the cooling and heating fan 10 in operation.

[0068] In some embodiments, the fan body 100 comprises a mounting frame 500, the heating element 200 is slidably connected to the mounting frame 500, the mounting frame 500 has an air outlet air duct 540, the heating element 200 avoids the air outlet air duct 540 when the handle 210 is in the first position 101, and the heating element 200 is located in the air outlet air duct 540 when the handle 210 is in the second position 102.

[0069] Referring to Figure 2 and Figure 4 When the handle 210 is in the first position 101, the heating element 200 avoids the air outlet air duct 540, and the cooling and heating fan 10 blows cold air; referring to Figure 3 and Figure 5 When the handle 210 is in the second position 102, the heating element 200 is located in the air outlet air duct 540, and the cooling and heating fan 10 blows warm air.

[0070] In some embodiments, the fan body 100 comprises a mounting frame 500, the heating element 200 is slidably connected to the mounting frame 500, the mounting frame 500 is provided with a first sliding member, the heating element 200 is provided with a second sliding member, and the second sliding member is in sliding cooperation with the first sliding member.

[0071] In this way, by providing the mounting frame 500 with the first sliding member and the heating element 200 with the second sliding member, and by using the second sliding member to slide with the first sliding member, the heating element 200 can be slidably connected to the mounting frame 500, and the cooling and heating fan 10 can be flexibly switched between cold air and warm air.

[0072] In some embodiments, a plurality of the micro switches 300 are located on the bottom of the fan body 100.

[0073] Therefore, the plurality of micro switches 300 are located at the bottom of the fan body 100, such as directly placed on the boss bottom of the heating element 200, which can prevent the cold and warm fan 10 from shaking due to touching, so that the operation of the micro switch 300 is more stable.

[0074] The working principle of the above cold and warm fan 10 is that when the cold and warm fan 10 needs to work in the warm air mode, the heating element 200 is moved to the position opposite to the air outlet, that is, the heating element 200 is located in the air outlet air duct 540, at this time, the second micro switch 320 is triggered by the handle 210 pressing part 212 at the bottom of the heating element 200, the second micro switch 320 is turned on, and a release signal is given to the PCB, the motor drives the fan wheel 110 to start working, and at the same time, the heating element 200 also starts working, and the cold and warm fan 10 starts to work in the warm air mode.

[0075] When it is needed to switch to the cold air working state, the heating element 200 is moved to the left side, so that the heating element 200 is completely away from the air outlet, that is, the handle 210 is in the first position 101, the heating element 200 avoids the air outlet air duct 540, at the same time, the second micro switch 320 is turned off, the first micro switch 310 is turned on, and the heating element 200 stops working, and the cold and warm fan 10 starts to switch to the cold air working state.
