[0053] The present invention provides a heater 100 .

[0054] Please refer to Figure 1 and Figure 2In some embodiments of the present application, the heater 100 includes:

[0055] The housing assembly 10 includes a lower housing 11 and at least one sliding housing 12 sleeved on the lower housing 11, so that the housing assembly 10 is retractable. The housing assembly 10 forms a heat dissipation channel 13, and the sliding housing 12 is provided with a heat dissipation port 121;

[0056] A heating component 20, the heating component 20 is disposed in the heat dissipation channel 13;

[0057] A lifting assembly 30, which is disposed in the housing assembly 10 and elastically supports the sliding housing 12. The lifting assembly 30 can drive the sliding housing 12 to extend; and

[0058] The lock-release assembly 40 locks the housing assembly 10 when the heater 100 is retracted, so that the sliding housing 12 is limited and fixed to the lower shell 11 and the lifting assembly 30 is in an elastically retracted state.

[0059] The heater 100 proposed in the present application includes a shell assembly 10 as an installation base and a heating assembly 20 arranged in the shell assembly 10. The heating assembly 20 can be an oil-filled heater or a resistive heater. The shell assembly 10 includes a plurality of mounting shells that are sequentially fitted, so that the shell assembly 10 can be retracted. The shell assembly 10 can be retracted in the height direction or in the horizontal direction. When the heater 100 is used, the shell assembly 10 can be stretched to extend the length of the heat dissipation channel 13. When the shell assembly 10 is retractable in the horizontal direction and a heat dissipation port 121 is provided on the top of each mounting shell, the heat dissipation area of ​​the heater 100 can be increased. When the shell assembly 10 is retracted in the height direction, a heat dissipation channel 13 similar to a chimney is formed inside the shell assembly 10. At this time, when the heating assembly 10 is When the heater 100 is in operation, the air in the heat dissipation channel 13 is heated and the gas expands, causing the density to decrease. The hot air rises upward and is discharged from the heat dissipation port 121 at the top to dissipate heat outward. At the same time, due to the reduction of the internal air pressure of the heat dissipation channel 13, the external cold air will enter the heat dissipation channel 13 from the air inlet 111 at the bottom, thereby realizing the gas exchange between the heat dissipation channel 13 and the external environment. In this process, the speed at which the hot air flows out of the heater 100 is controlled by the heat, so that the heater 100 can automatically adjust the speed of the heat dissipation and the air outlet according to the temperature of the internal gas, so that the heater 100 dissipates heat outward evenly. When the heater 100 is not in use, the shell assembly 10 can be shrunk to reduce the volume of the heater 100, reduce the space occupied by the heater 100, and improve the storage portability of the heater 100.

[0060] The heater 100 also includes a lifting assembly 30 arranged in the shell assembly 10 and a lock-release assembly 40 for locking the shell assembly 10 when the shell assembly 10 is retracted, wherein the lifting assembly 30 is an elastic lifting assembly 30, which at least includes an elastic support member for elastically supporting the sliding shell 12, and the elastic lifting structure can be but is not limited to a gas spring 313, an elastic air bag, a spring 313, etc., which are not limited here, so that the two ends of the elastic lifting structure are respectively abutted against the lower shell 11 of the shell assembly 10 and the sliding shell 12 that can be extended to the top, so that the elastic lifting structure can support the sliding shell 12, and when the elastic lifting structure is in a normal extended state, the sliding shell 12 and the lower shell 11 remain in an extended state, and when the sliding shell 12 slides down relative to the lower shell 11, the elastic lifting structure is compressed to produce a downward movement. The elastic force on the upper shell 12 is applied to the sliding shell 12. With this arrangement, the top sliding shell 12 can always be under a certain pressure, and the problem of the heater 100 becoming shorter during normal use will not occur. When the heater 100 is not in use, the sliding shell 12 is lowered and folded with the lower shell 11, and the locking assembly 40 is used to lock the sliding shell 12 and the lower shell 11, so that the heater 100 maintains structural stability in the contracted state and avoids the problem of the sliding shell 12 popping out under the elastic force of the lifting structure. The locking assembly 40 locks the sliding shell 12 and the lower shell 11 in a manner that the sliding shell 12 and the lower shell 11 are magnetically connected, snap-fitted, threadedly connected, bolted with bolts or latches, or fixed with binding parts such as cable ties, which is not limited here.

[0061] Therefore, it can be understood that the technical solution of the present invention is to set an elastic lifting component 30 and a lock-release component 40 in the shell component 10, the lifting component 30 is used to support the sliding shell 12 and make the sliding shell 12 have an upward tendency, and the lock-release component 40 locks the sliding shell 12 with the fixed shell when the shell component 10 is contracted; when the heater 100 needs to be used, the lock-release component 40 is unlocked, and at this time, the lifting component 30 is restored from the original contracted state to the extended state, and in this process, the sliding shell 12 is driven to rise to achieve the extension of the shell component 10; that is, the technical solution of the present invention can shrink the heater 100 to reduce the storage volume when the heater 100 is not in use, and the structural stability of the heater 100 in the storage state can be maintained by the lock-release component 40, and the elastic lifting component 30 can be used when the heater 100 needs to be used, only the lock-release component 40 needs to be unlocked to make the heater 100 automatically extend, without the need for the user to lift and pull the heater 100, thereby improving the convenience of use of the heater 100.

[0062] In some embodiments, the heat dissipation port 121 of the shell assembly 10 can be opened on the top surface of the shell assembly 10. When the shell assembly 10 is extended in the horizontal direction, the heat dissipation port 121 can be opened on the top surface of the lower shell 11 or one or each sliding shell 12. When the shell assembly 10 is extended in the height direction, the heat dissipation port 121 is opened on the top surface of the sliding shell 12 extended to the highest position. With this arrangement, when the hot air in the shell assembly 10 rises upward, it can be directly dissipated from the top without causing the hot air to collide with the top wall of the shell assembly 10; in some embodiments, the heat dissipation port 121 on the top surface of the shell assembly 10 is covered with an air outlet grille 15 to prevent foreign debris from falling into the heat dissipation channel 13 from the top heat dissipation port 121, and to prevent users from accidentally putting their hands into the heat dissipation channel 13 and being burned by the heating component 20, thereby improving the safety of the heater 100. In some embodiments, the heat dissipation port 121 is provided on the side of the housing assembly 10 at a certain distance from the top surface. It can be provided on only one side, or multiple heat dissipation ports 121 can be provided along the circumference. In this case, warm air can be radiated from the housing assembly 10 to the circumference, so that the temperature rises evenly around the heater 100, thereby improving the user's comfort experience. Of course, the heat dissipation ports 121 can be provided on both the top surface and the side surface of the housing assembly 10, increasing the size of the opening for the housing assembly 10 to dissipate heat outward, and increasing the heat dissipation range of the heater 100, so that the ambient temperature around the heater 100 can quickly reach a comfortable range, thereby improving the user's experience.

[0063] Similarly, the air inlet 111 can be opened on the bottom wall of the lower shell 11, or can be opened on the side wall at a distance from the bottom wall. When the air inlet 111 is opened on the bottom wall, the shell assembly 10 also includes a foot pad 17, and the foot pad 17 is padded on the bottom of the shell assembly 10 so that the bottom of the shell assembly 10 is suspended to form an air inlet gap. In some embodiments, the air inlet 111 is covered with an air inlet grille to prevent foreign matter from entering the heat dissipation channel 13 with the air flow, thereby improving the safety of the heater 100.

[0064] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the lifting assembly 30 includes an elastic support member 31, one end of the elastic support member 31 abuts against the lower shell 11, and the other end of the elastic support member 31 abuts against the sliding shell 12 located at the top.

[0065] In this embodiment, the lifting assembly 30 includes an elastic support member 31, which can be but is not limited to a gas spring 313, an elastic airbag, a spring 313, etc., and one end of the elastic support member 31 abuts against the lower shell 11, and the other end abuts against the sliding shell 12 that can be extended to the top. When the elastic support member 31 is in a normal extended state, the sliding shell 12 and the lower shell 11 remain in an extended state. When the sliding shell 12 slides down relative to the lower shell 11, the elastic support member 31 is compressed to generate an upward elastic force and apply it to the sliding shell 12. With this arrangement, the sliding shell 12 at the top can always be under a certain pressure, and the problem of the heater 100 becoming shorter in normal use will not occur; when the shell assembly 10 is unlocked from the contracted state, the elastic support member 31 extends to support the sliding shell 12 to rise, so that the heater 100 automatically extends without the need for the user to lift and pull the heater 100, thereby improving the convenience of use of the heater 100.

[0066] In some embodiments of the present application, the elastic support member 31 maintains an elastically contracted state.

[0067] It is understandable that when the heater 100 is contracted, the elastic support member 31 is compressed and also remains in a contracted state, so that an elastic force can be provided to extend the heater 100 when the heater 100 is unlocked. In this embodiment, the elastic support member 31 is always kept in an elastic contracted state, that is, when the housing assembly 10 is in an extended state, the elastic support member 31 is also in a compressed state. With such a configuration, the sliding housing 12 at the top can always be subjected to a certain pressure, and the problem of the height of the heater 100 becoming shorter during normal use will not occur, thereby improving the structural stability of the heater 100 in use.

[0068] Please refer to Figure 4 In some embodiments of the present application, the elastic support member 31 is a gas spring assembly 311, one end of the gas spring assembly 311 is fixed to the lower shell 11, and the other end is connected to the sliding shell 12 located at the top.

[0069] In this embodiment, the elastic support member 31 is a gas spring assembly 311, which generally includes a pressure cylinder, a piston rod, a piston, and a filler (an inert gas or an oil-gas mixture) filled in the pressure cylinder. The cross-sectional area of ​​the piston rod is smaller than that of the piston, thereby generating a pressure difference on both sides of the piston. When the gas spring 313 acts, the pressure difference on both sides of the piston is utilized to keep the piston rod in an ejected state to support the sliding housing 12. In some embodiments, fixing members 312 may be provided on both the lower housing 11 and the top sliding housing 12 to respectively connect the pressure rod and the piston rod of the gas spring assembly 311, so that the gas spring assembly 311 and the housing assembly 10 maintain a stable connection relationship, thereby preventing the gas spring assembly 311 from being skewed or misaligned.

[0070] Please refer to Figures 1 to 3 In some embodiments of the present application, the elastic support member 31 is a spring 313, one end of the spring 313 is fixed to the lower shell 11, and the other end is connected to the sliding shell 12 located at the top.

[0071] In this embodiment, the elastic support member 31 is a spring 313, so that the two ends of the spring 313 are respectively abutted against the lower shell 11 of the shell assembly 10 and the top sliding shell 12, and the spring 313 is in a compressed state, which can provide an upward supporting force to the sliding shell 12, so that the sliding shell 12 has an upward drive, thereby maintaining the structural stability of the heater 100 in the extended state when the heater 100 is in use.

[0072] In some embodiments, the lifting assembly 30 can be provided with a combination of at least two or at least one elastic support member 31, for example, using at least two gas springs 313, two springs 313, or a combination structure of at least one gas spring 313 and at least one spring 313, which is not limited here. This can increase the elastic supporting force on the sliding shell 12 and further improve the structural stability of the heater 100 in the extended state.

[0073] Please refer to Figures 1 to 3 In some embodiments of the present application, the lifting assembly 30 also includes a guide structure 32, which includes at least two telescopic parts 321 slidably connected along the telescopic direction of the shell assembly 10, wherein one telescopic part 321 is connected to the lower shell 11, and the other telescopic part 321 is connected to the sliding shell 12 located at the top.

[0074] In this embodiment, the lifting assembly 30 includes a guide structure 32, which includes at least two telescopic members 321 that are slidably connected in sequence. The telescopic members 321 are mostly made of hard materials and can maintain a high degree of alignment in the telescopic direction of the shell assembly 10, wherein one of the telescopic members 321 of the guide structure 32 is connected to the lower shell 11, so that a telescopic member 321 is connected to the telescopic member 321 located at the top. Of course, when at least two sliding shells 12 are provided, more than three telescopic members 321 can also be provided, so that a sliding shell 12 is connected to a telescopic member 321; the provision of the guide structure 32 can not only improve the supporting effect of the lifting assembly 30 on the sliding shell 12, but also guide the telescopic direction of the shell assembly 10 during the telescopic process of the elastic support member 31 and the shell assembly 10, so as to avoid the deflection of the sliding shell 12, which leads to an increase in the friction between the shell assembly 10 and affects the stability of the telescopic process. It should be noted that in this embodiment, the telescopic member 321 can be a telescopic slat, a telescopic sleeve or other structures, which are not limited here.

[0075] Please refer to Figure 3In some embodiments of the present application, the telescopic member 321 is a telescopic sleeve, each telescopic sleeve is fitted with each other and is interconnected internally to form an accommodating space, and the elastic support member 31 is disposed in the accommodating space.

[0076] In this embodiment, the lifting assembly 30 is a telescopic sleeve, and each telescopic sleeve is fitted together, so that the contact area between two adjacent telescopic members 321 can be increased, and the telescopic members 321 can be mutually limited in the horizontal direction to avoid misalignment or separation, thereby improving the structural strength and sliding stability of the lifting assembly 30. Among them, the sliding sleeve rod can be polygonal, circular or other morphological structures, which are not limited here.

[0077] Furthermore, the internal spaces of the various telescopic sleeves are interconnected to form an accommodating space, and the elastic support member 31 is arranged in the accommodating space, which can not only protect the elastic support member 31, but also allow the guide structure 32 and the elastic support member 31 to be arranged at the same position, thereby reducing the space occupied by the lifting assembly 30, and the accommodating space can be used to guide the extension and retraction process of the elastic support member 31, thereby avoiding that when an elastic support member 31 such as a spring 313 is used, the spring 313 is bent under force instead of being compressed, thereby affecting the performance stability.

[0078] Please refer to Figure 2 and Figure 3 In some embodiments of the present application, both ends of the accommodating space are covered with blocking members 322 , and both ends of the elastic supporting member 31 are respectively abutted against the two blocking members 322 .

[0079] In this embodiment, sealing members 322 are provided at both ends of the guide structure 32, so that the elastic support member 31 and the guide structure 32 are configured as an integrated structure, which facilitates the disassembly and assembly between the lifting assembly 30 and the shell assembly 10, thereby improving the convenience of disassembly and assembly of the heater 100.

[0080] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the heater 100 further includes a buffer assembly 50, which is transmission-connected to the sliding shell 12 to provide a buffer force in the opposite direction of the movement direction for the sliding shell 12 during at least one process of the sliding shell 12 rising and falling.

[0081] The present application utilizes an elastic lifting assembly 30 to automatically push the sliding shell 12 upward when the heater 100 is unlocked, thereby realizing automatic extension of the heater 100; it is understandable that the greater the degree of contraction of the elastic support member 31, the greater the elastic force generated, and the greater the speed at which the sliding shell 12 is pushed upward. When the heater 100 is unlocked and the elastic support member 31 is released, the elastic force exerted on the sliding shell 12 is relatively large. At this time, the sliding shell 12 is prone to being ejected quickly, which may pose a safety hazard. If the heater 100 is pressed down and contracted with a large force, the sliding shell 12 may also easily descend quickly, causing a collision of internal components.

[0082] In this embodiment, a buffer assembly 50 is provided in the heater 100. The buffer assembly 50 can be used to provide a downward buffer force for the sliding housing 12 to limit the rising speed of the sliding housing 12 during the rising process of the sliding housing 12; the buffer assembly 50 can also be used to provide an upward buffer force for the sliding housing 12 to limit the descending speed of the sliding housing 12 during the descending process of the sliding housing 12; that is, the buffer assembly 50 can limit the moving speed of the sliding housing 12 during the rising or descending process of the sliding housing 12. For example, in the following embodiment, a traction rope 51 is provided to limit the rising speed of the sliding housing 12. Similarly, a traction structure can be provided to push or pull the sliding housing 12 upward to limit the descending speed of the sliding housing 12. It can also be provided that a buffer assembly 50 simultaneously limits the moving speed of the sliding housing 12 during the rising and descending process of the sliding housing 12, or two sets of slide groove structures can be provided to limit the moving speed of the sliding housing 12 during the rising and descending process of the sliding housing 12 respectively, which is not limited here. The buffer assembly 50 can be provided with a traction rope 51, a pressure cylinder, etc., or an elastic structure opposite to the above-mentioned elastic support member 31.

[0083] Please refer to Figure 8 In some embodiments of the present application, the buffer assembly 50 includes:

[0084] A traction rope 51, one end of which is connected to the sliding housing 12 at the top, and the other end of which extends to the lower housing 11; and

[0085] A driving member is connected to the traction rope 51 to provide a downward pulling force to the traction rope 51 .

[0086] In this embodiment, the buffer assembly 50 is configured as a combination structure of a traction rope 51 and a driving member. One end of the traction rope 51 is connected to the sliding shell 12 at the top, so that the other end of the traction rope 51 naturally droops and is connected to the driving member, so that the driving member applies a downward pulling force to the traction rope 51, thereby pulling the top mounting shell downward. At this time, the sliding shell 12 is simultaneously subjected to the elastic supporting force and the traction force of the elastic support member 31. The pulling force applied to the traction rope 51 by the driving member is controlled to adjust the external force finally received by the sliding shell 12, so as to control the rising speed of the sliding shell 12, avoid the sliding shell 12 rising too fast, and improve the safety of the extension process of the heater 100. In addition, when the heater 100 needs to be contracted, the traction rope 51 can also be pulled down to drive the sliding shell 12 to slide down. At this time, the sliding speed of the sliding shell 12 can be controlled by controlling the recovery speed of the traction rope 51. The driving member may be a motor or a cylinder or a liquid cylinder, etc., which drives a winding mechanism or other structures to recover or release the traction rope 51. Of course, the traction rope 51 may also be manually retracted and released. For example, a holding structure such as a handle may be provided so that the winding mechanism can be manually rotated to retract and release the traction rope 51. No limitation is made here. When the driving member is a driving motor, the rotation speed of the driving motor can be controlled to control the pulling force of the driving member on the traction rope 51, thereby controlling the extension and retraction speed of the heater 100.

[0087] Please refer to Figure 8 In some embodiments of the present application, when the elastic support member 31 is a spring 313 , the traction rope 51 is passed through the inner side of the spring 313 .

[0088] In this embodiment, the elastic support member 31 is a spring 313, and the spring 313 is a spiral extension structure, so that the traction rope 51 is passed through the inside of the spring 313, so that the lifting assembly 30 and the buffer assembly 50 can be set at the same position, reducing the space occupied by the lifting assembly 30 and the buffer assembly 50 in the shell assembly 10, thereby reducing the volume of the shell assembly 10 and reducing the volume of the heater 100.

[0089] In some embodiments, the lifting assembly 30 also includes a guide structure 32 formed by at least two telescopic sleeves. At this time, the traction rope 51 can be set in the guide structure 32 to protect the traction rope 51 and prevent the traction rope 51 from being continuously in a hot air environment and easily damaged. It can also limit the traction rope 51 and prevent the traction rope 51 from being scattered in the heat dissipation channel 13 and hooking or hanging on other structures such as the heating assembly 20, causing the movement of the traction rope 51 to be interfered with and easily cause damage to other component structures, thereby improving the stability of the heater 100.

[0090] Please refer to Figure 5In some embodiments of the present application, the buffer assembly 50 includes at least two sealing sleeves 52 which are sequentially fitted with each other, wherein one sealing sleeve 52 is connected to the lower shell 11, and the other sealing sleeve 52 is connected to the sliding shell 12 located at the top;

[0091] The interiors of the sealing sleeves 52 are interconnected to form an air cavity, wherein a vent hole 521 communicating with the air cavity is formed on the side wall of at least one sealing sleeve 52 . The sliding housing 12 is raised and lowered to cause the buffer assembly 50 to expand and contract so that the air cavity is inflated and deflated through the vent hole 521 .

[0092] In this embodiment, the buffer assembly 50 includes at least two sealing sleeves 52 which are slidably connected in sequence and fit together. The sealing sleeves 52 are interconnected to form an air cavity. When the air cavity is inflated, the air pressure inside the air cavity increases, which will cause the sealing sleeve 52 to slide relatively and stretch, thereby increasing the volume of the air cavity and reducing the air pressure; when the air cavity is exhausted, the air pressure inside the air cavity decreases, which will cause the sealing sleeve 52 to slide relatively and shrink, thereby reducing the volume of the air cavity and increasing the air pressure inside the air cavity to a balanced state. The buffer component 50 expands and contracts with the shell component 10. At this time, when the heater 100 does not need to expand or contract, the air pressure difference between the air cavity and the outside world will maintain the length of the buffer component 50 unchanged. When the buffer component 50 is extended along with the shell component 10, the air cavity volume of the buffer component 50 increases, causing the air pressure in the air cavity to decrease. At this time, the air pressure difference between the air cavity and the outside world will produce resistance that hinders the extension of the buffer component 50, thereby buffering the extension process of the shell component 10 and preventing the shell component 10 from extending too quickly. However, in this process, the air pressure difference between the air cavity and the outside world will also cause external gas to enter the air cavity from the vent 521, so as to increase the air pressure inside the air cavity and balance the air pressure inside and outside the air cavity, thereby avoiding the buffer component 50 from expanding too quickly. The impact assembly 50 always applies a retracting force to the shell assembly 10 to prevent the shell assembly 10 from shrinking due to the resistance of the buffer assembly 50 when the shell assembly 10 is in an extended state; when the buffer assembly 50 shrinks with the shell assembly 10, the air pressure in the air cavity increases. At this time, the air pressure difference between the air cavity and the outside world will produce resistance that hinders the shrinkage of the buffer assembly 50, thereby buffering the shrinkage process of the shell assembly 10 and preventing the shell assembly 10 from shrinking too quickly. However, in this process, the air pressure difference between the air cavity and the outside world will also cause the gas in the air cavity to be discharged outward from the vent 521 to reduce the air pressure inside the air cavity and balance the air pressure inside and outside the air cavity, thereby preventing the buffer assembly 50 from always applying a retracting force to the shell assembly 10.

[0093] Please refer to Figure 2 and Figure 3In some embodiments, the lifting assembly 30 is provided with a guide structure 32 formed by at least two telescopic sleeves fitting together. In this case, the guide structure 32 can be reused as a buffer assembly 50, that is, the two adjacent telescopic sleeves are kept sealed, so that the internal space of each telescopic sleeve forms an air cavity; for example, sealing oil or sealing grease can be added between the walls of the two adjacent and mutually fitting telescopic sleeves, which can not only play a sealing role, but also a lubricating role, so as to prevent the two telescopic sleeves from being easily worn and leaking during the telescopic process; of course, a seal 323 can be arranged around the sleeve position of the two adjacent telescopic sleeves, so that at least part of the seal 323 is sandwiched between the walls of the two telescopic sleeves, which is not limited here. With such an arrangement, the shell assembly 10 of the heater 100 can be guided and limited during the telescopic process, and the lifting process of the shell assembly 10 can also play a buffering and speed limiting role, thereby improving the stability and safety of the heater 100 during the telescopic process.

[0094] Please refer to Figures 5 to 7 In some embodiments of the present application, the sealing sleeve 52 is provided with two vent holes 521, and the buffer assembly 50 also includes two one-way valves 53, one of the one-way valves 53 is provided at one of the vent holes 521, and one of the vent holes 521 is used to let air into the air cavity as an air inlet, and the other vent hole 521 is used to deflate the air cavity as an exhaust hole.

[0095] In this embodiment, two vent holes 521 connected to the air cavity are provided on the sealing sleeve 52, at least one of the vent holes 521 is used as an air inlet to inflate the air cavity, and one of the vent holes 521 is used as an exhaust hole to allow the air cavity to be exhausted to the outside; at the same time, one-way valves 53 are respectively provided on the air inlet and the exhaust port to respectively control the opening and closing states of the air inlet and the exhaust port; when there is no need to extend or retract the heater 100, the two one-way valves 53 are closed, at which time the air cavity is completely sealed and air cannot be taken in or exhausted, and the sealing sleeves 52 of the buffer assembly 50 cannot slide relative to each other, so that the shell assembly 10 can maintain the structural stability of the current state; and when it is necessary to use When the heater 100 contracts, the one-way valve 53 on the exhaust port is opened so that the air cavity can be exhausted outward in one direction, so that the buffer component 50 can contract to avoid hindering the contraction of the heater 100. In addition to controlling the opening and closing of the exhaust port, the one-way valve 53 can also control the airflow direction of the exhaust port to prevent external gas from entering the air cavity from the exhaust port; when the shell component 10 needs to be extended, the one-way valve 53 at the air inlet position is opened so that the air cavity can be inflated so that the buffer component 50 can extend with the shell component 10 to avoid affecting the extension of the heater 100. Similarly, the one-way valve 53 at the air inlet can be used to control the opening and closing of the air inlet and the airflow direction.

[0096] Please refer to Figure 1 and Figure 2In some embodiments of the present application, the elastic support member 31 is disposed in the air cavity, and two ends of the elastic support member 31 are respectively in contact with the cavity walls at both ends of the air cavity.

[0097] In this embodiment, the elastic support member 31 is arranged in the air cavity. In this way, the buffer assembly 50 can be used to protect the elastic support member 31, and the elastic support member 31 and the buffer assembly 50 can be arranged at the same position, reducing the space occupied by the lifting assembly 30 and the buffer assembly 50 in the shell assembly 10, thereby reducing the volume of the shell assembly 10 and the volume of the heater 100. The lifting assembly 30 and the buffer assembly 50 are arranged as an integrated structure, which is convenient for disassembly and assembly of the heater 100.

[0098] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the lock-release structure includes:

[0099] A first connecting portion 41, which is disposed on the lower shell 11; and

[0100] The second connection part 42 is disposed on the top of the sliding housing 12 . The sliding housing 12 is lowered or raised to connect or separate the second connection part 42 from the first connection part 41 .

[0101] In this embodiment, the lock-release structure includes a first connection part 41 and a second connection part 42 respectively arranged on the lower shell 11 and the sliding shell 12. When the sliding shell 12 slides relative to the lower shell 11, the second connection part 42 will be driven to approach or move away from the first connection part 41. When the heater 100 is contracted, that is, the sliding shell 12 is contracted to the lower shell 11, the first connection part 41 and the second connection part 42 are locked with each other, thereby maintaining the structural stability of the heater 100 in the contracted state and preventing the heater 100 from popping out under the action of the lifting assembly 30. Among them, the first connection part 41 and the second connection part 42 can be set as magnetic suction parts, so that the first connection part 41 and the second connection part 42 are magnetically connected and locked with each other; the first connection part 41 and the second connection part 42 can also be respectively set as buckles and clamping parts for clamping fit; or the first connection part 41 and the second connection part 42 can also be set as bolted connection or other detachable connection matching structures or the hook 421 and lock buckle 411 structures in the following embodiments, which will not be repeated here.

[0102] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the second connecting portion 42 extends from the top wall of the sliding shell 12 to the lower shell 11 and is provided with a hook 421. The first connecting portion 41 is provided with a lock 411. The hook 421 is hooked on the lock 411 to connect the first connecting portion 41 and the second connecting portion 42.

[0103] In this embodiment, the first connecting portion 41 and the second connecting portion 42 are a matching structure of a hook 421 and a lock buckle 411, wherein the first connecting portion 41 extends downward from the top wall of the sliding housing 12, and a hook 421 structure is formed at the end of the first connecting portion 41, and the second connecting portion 42 is arranged on the lower shell 11, and a lock buckle 411 is formed, and the lock buckle 411 has a supporting portion and an abutting portion protruding from the side of the supporting portion, and a clamping space is formed below the abutting portion. When the second connecting portion 42 is pressed downward, the hook 421 is hooked in the clamping space and locked with the abutting portion, thereby The first connection part 41 and the second connection part 42 are connected; when the hook 421 and the lock buckle 411 need to be unlocked, the hook 421 can be disengaged from the locking space by applying a certain external force, or the first connection part 41 and the second connection part 42 can be configured as a press-lock structure in the following embodiment, similar to the function of a rebounder. When the first connection part 41 and the second connection part 42 are in a locked state, the first connection part 41 and the second connection part 42 can be unlocked by pressing down the second connection part 42, thereby improving ease of use and reducing the risk of damage.

[0104] In some embodiments, the first connection portion 41 may be provided with a hook 421 , and the second connection portion 42 may be provided with a lock 411 , which will not be described in detail herein.

[0105] In some embodiments of the present application, the lock-release structure is a press-lock structure, and the first connection portion 41 is pressed downward relative to the second connection portion 42 to connect and separate the hook 421 and the lock 411.

[0106] In this embodiment, the lock release structure is set as a press lock structure, that is, when the second connection part 42 is pressed down with the sliding housing 12, the hook 421 of the second connection part 42 can be connected with the lock 411 of the first connection part 41. When the sliding housing 12 and the second connection part 42 are pressed down in the locked state, the hook 421 can be disengaged from the lock 411 to achieve unlocking, thereby improving the convenience of locking and releasing the lock release structure. Among them, the press lock structure can be a track structure similar to a "W" structure provided on the lock 411, and the two ends of the W track structure are open. When the hook 421 of the second connection part 42 is pressed down with the sliding housing 12, it slides into the track from one end to release the pressure on the sliding housing 12. At this time, under the action of the lifting assembly 30, the sliding housing 12 and the second connection part 42 will rebound upward. At this time, the hook 421 will enter the middle of the W track structure along the track and hook at this position, so that the first connection part 41 and the second connection part 42 are connected. When the sliding housing 12 is pressed down, the hook 421 will enter the middle of the W track structure along the track and hook at this position, so that the first connection part 41 and the second connection part 42 are connected. When the sliding housing 12 and the second connecting part 42 are connected, the hook 421 slides down along the track to the bottom of the track. When the pressure on the sliding housing 12 is released, the sliding housing 12 and the second connecting part 42 will rebound upward under the action of the lifting assembly 30. At this time, the hook 421 will be disengaged from the opening at one end of the W track structure, so that the first connecting part 41 and the second connecting part 42 are unlocked; in some embodiments, the lock release structure can be set as a rebounder or other push lock buckle 411 interface. Of course, the push lock buckle structure can also be the structural form in the following embodiments, which will not be repeated here.

[0107] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the second connecting portion 42 further includes a pressing portion 422 disposed above the hook 421, and the top surface of the lock buckle 411 is an inclined surface 412 inclined from top to bottom toward the side away from the side opening;

[0108] When the first connection part 41 and the second connection part 42 are unlocked, the sliding shell 12 and the first connection part 41 slide down so that the pressing part 422 abuts against the inclined surface 412 and tilts along the inclined surface 412, and the hook 421 moves out of the opening of the locking space and disengages from the locking space, so that the first connection part 41 is separated from the second connection part 42.

[0109] In this embodiment, the second connecting portion 42 includes a hook 421 and a pressing portion 422 arranged above the hook 421, the pressing portion 422 extends to the side of the hook 421, and the top surface of the abutment portion on the top of the lock buckle 411 is set as a downwardly inclined inclined surface 412. When the hook 421 of the second connecting portion 42 is pressed down with the sliding shell 12, the hook 421 will produce a certain deformation or the first connecting portion 41 will be elastically bent as a whole to withdraw to the side away from the locking space, so that the hook 421 can enter the locking space to connect the first connecting portion 41 and the second connecting portion 42. At this time, the hook 421 is connected to the bottom of the locking space. The wall spacing is arranged; when unlocking is required, the sliding shell 12 is pressed to press the second connecting part 42 downward. At this time, the pressing part 422 of the second connecting part 42 is pressed on the top inclined surface 412 of the first connecting part 41, and tilts along the inclined surface 412 during the continuous downward pressing of the second connecting part 42, so that the hook 421 rotates to the side away from the locking space and withdraws from the locking space, so that the first connecting part 41 and the second connecting part 42 are unlocked, and the pressure on the sliding shell 12 is released. At this time, under the action of the lifting assembly 30, the sliding shell 12 and the second connecting part 42 rise away from the lower shell 11 and the first connecting part 41.

[0110] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the housing assembly 10 further includes a support plate 16, so the support plate 16 is disposed in the lower shell 11, and divides the lower shell 11 into a heating space 161 and an air inlet space 162 arranged in an upper and lower manner, and the support plate 16 is provided with a ventilating opening connecting the air inlet space 162 and the heating space 161;

[0111] The heating assembly 20 is disposed on the support plate 16 and is located in the heating space 161 . The lifting assembly 30 is connected to the support plate 16 .

[0112] In this embodiment, a support plate 16 is provided in the shell assembly 10 for fixing and supporting the heating assembly 20, and dividing the internal space of the bottom mounting shell into an air inlet space 162 and a heating space 161 which are stacked from bottom to top. An air inlet 111 which is connected to the air inlet space 162 is provided on the mounting shell. The air inlet 111 can be provided on the side wall of the mounting shell or on the bottom of the mounting shell. With such a configuration, after the airflow enters the shell assembly 10 from the air inlet 111 under the action of the temperature difference between the inside and outside and the air pressure, it will flow through the heating assembly 20 and be heated, and then continue to flow upward and be discharged outward from the top heat dissipation port 121.

[0113] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the support plate 16 is provided with an escape opening, and one end of the lifting assembly 30 is passed through the escape opening.

[0114] In this embodiment, an avoidance hole is opened on the support plate 16, so that one end of the lifting assembly 30 can pass through the avoidance hole to enter the air inlet space 162 under the support plate 16, and the air inlet space 162 is used to accommodate part of the lifting assembly 30 to avoid increasing the height of the shell assembly 10 when it is extended and stored.

[0115] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the shell assembly 10 further includes a support frame 163 , which is fixed to a side of the support plate 16 facing the air inlet space 162 and connected to the lifting assembly 30 .

[0116] In this embodiment, a support frame 163 is fixed under the support plate 16, so that the part of the lifting assembly 30 located under the support plate 16 can be fixedly connected by the support frame 163, thereby improving the installation stability of the lifting assembly 30 in the shell assembly 10, avoiding the displacement and shaking of the lifting assembly 30 during the extension and retraction process, and improving the stability of the overall activity process of the heater 100.

[0117] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the housing assembly 10 includes at least two sliding housings 12 that fit together, and two adjacent sliding housings 12 are locked in an extended state. The lifting assembly 30 drives the sliding housing 12 at the top to rise to drive each sliding housing 12 to rise in sequence.

[0118] In this embodiment, the housing assembly 10 includes at least two sliding housings 12 that fit each other. One end of the sliding housing 12 located on the outside is provided with an opening for the other sliding housing 12 to enter and exit. When one of the sliding housings 12 slides out to a preset length relative to the other sliding housing 12, the two sliding housings 12 are limitedly locked. This can be achieved by protruding a traction portion on the inner wall of the outer sliding housing 12 adjacent to the opening, and protruding a stop portion on the outer wall of the inner sliding housing 12 inserted into one end of the outer sliding housing 12. When the two sliding housings 12 are in a retracted state, the stop portion and the traction portion are arranged oppositely and at intervals. When the lifting assembly 30 drives one of the sliding housings 12 to extend relative to the other sliding housing 12, the stop portion abuts against the traction portion. At this time, the lifting assembly 30 can drive the other sliding housings 12 by pulling one of the sliding housings 12. Extension, there is no need to set up multiple sliding parts to connect with each sliding shell 12; it is also possible to set a guide rail and a bracket between the two sliding shells 12 that fit each other, the bracket is set at the end of the inner sliding shell 12 inserted into the outer sliding shell 12, and is provided with a slide groove for sliding connection with the guide rail, so that the guide rail is located in the slide groove, and the groove wall of the slide groove can also be provided with a roller 18 that rolls and abuts against the guide rail; at the same time, an auxiliary pulley structure is set at the end of the guide rail close to the opening, and the auxiliary pulley structure rolls and abuts against the side wall of the inner sliding shell 12. When the two sliding shells 12 are extended, the bracket and the auxiliary pulley structure abut. At this time, the two sliding shells 12 are relatively extended to the extreme position, and no relative sliding occurs in the extension direction. At this time, if one of the two sliding shells 12 continues to be subjected to an upward external force, it will pull the two sliding shells 12 to slide up synchronously.

In this arrangement, when looking down from above the heater 100, only the sliding shell 12 at the top can be seen, and the fitting gap between the lower shell 11 and the sliding shell 12 or between the two adjacent sliding shells 12 cannot be seen, which makes the product more integrated and can also prevent foreign debris from falling into the heat dissipation channel 13 from the gap between the lower shell 11 and the sliding shell 12 or between the two adjacent sliding shells 12, thereby improving the safety of the heater 100.

[0121] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the sliding housing 12 is inserted into the lower housing 11 .

[0122] In this embodiment, the sliding shell 12 is inserted into the lower shell 11, and when at least two sliding shells 12 are provided, the sliding shell 12 located at the upper side is inserted into the sliding shell 12 located at the lower side. With such a configuration, the size of the lower shell 11 located at the bottom is larger, and the center of gravity of the heater 100 is lowered, thereby making it easier to place the heater 100 stably and reducing the risk of tipping over of the heater 100, thereby improving the safety of use of the heater 100.
