[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0042] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] Combine the following Figures 1 to 8 , describing an embodiment of the present invention.

[0046] like Figures 1 to 3 As shown, according to an embodiment of the present invention, a heater is disclosed, including a casing 1, an air inlet assembly 2, a power cord 3 and a fixing structure, wherein the casing 1 has an air inlet 11 and a wire hole 12, the air inlet assembly 2 is connected to the casing 1, the air inlet assembly 2 is arranged at the air inlet 11, the power cord 3 is passed through the wire hole 12, the power cord 3 can be wrapped around the outer periphery of the air inlet assembly 2, the fixing structure is arranged on the casing 1 and / or the air inlet assembly 2, and the fixing structure is used to fix the plug 31 of the power cord 3.

[0047] The heater of the present application is provided with a fixed structure. When the heater is not in use, the power cord 3 can be wrapped around the periphery of the air inlet component 2 for storage, and the plug 31 of the power cord 3 can be fixed by the fixed structure to improve the stability and reliability of the winding and storage of the power cord 3, thereby avoiding the problem that the power cord 3 is scattered due to the external force on the plug 31 in a free state, causing inconvenience in use and safety hazards.

[0048] It is understandable that the scattered power cord 3 requires additional manpower to store it, and not storing the power cord 3 is inconvenient for storing and carrying the heater. At the same time, the scattered power cord 3 has the risk of contacting water sources, which can easily cause the risk of electric shock when in use. Therefore, it is particularly important to ensure that the power cord 3 is stably stored when not in use.

[0049] The outer casing 1 is the outer shell of the heater. The inner part of the casing 1 has a cavity for installing the internal structure, which mainly plays the role of protecting the internal structure and facilitating the installation of the internal structure.

[0050] The housing 1 can generally be a plastic housing, a metal housing, etc., and this embodiment does not impose any specific limitation.

[0051] Specifically, the shape of the housing 1 can be cylindrical, solid geometric, etc. In this embodiment, the housing 1 is set as a three-dimensional square shell as an example for description, but it is not limited to this.

[0052] The air inlet 11 is connected to the inner cavity of the casing 1 , so that external air can flow into the inner cavity of the casing 1 through the air inlet 11 .

[0053] The shape of the air inlet 11 may be circular, elliptical or geometric, etc. In this embodiment, the air inlet 11 is set to be circular as an example for description, but it is not limited to this.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments, at least a portion of the air inlet assembly 2 extends outside the housing 1 through the air inlet 11 , and the power cord 3 is wrapped around the portion of the air inlet assembly 2 extending outside the housing 1 .

[0055] By winding the power cord 3 around the portion of the air inlet assembly 2 extending outside the housing 1 , the power cord 3 can be wound and stored without setting up an additional structure, thereby simplifying the structure of the entire machine.

[0056] In terms of specific structure, in some embodiments, the air inlet assembly 2 includes an air inlet grille 21 and an air filter cover 22, wherein the air inlet grille 21 is arranged at the air inlet 11, and a portion of the air inlet grille 21 extends to the outside of the casing 1 through the air inlet 11, the air filter cover 22 is connected to the casing 1, the air filter cover 22 is covered on the air inlet grille 21, and the air filter cover 22 has an air filter port 221 connected to the air inlet grille 21, and a gap 13 is provided between the air filter cover 22 and the casing 1, and the power cord 3 is wrapped around the portion of the air inlet grille 21 extending to the outside of the casing 1 through the gap 13.

[0057] The air filter cover 22 can perform an initial filter on the air to filter out large particles of impurities in the air and prevent the impurities from being sucked into the casing 1. The air inlet grille 21 can both perform a secondary filter on the air and balance the incoming air so that it can flow more evenly to the heating part, allowing the warm air to flow more evenly to all locations, thereby improving the uniformity of heating. A gap 13 is formed between the air filter cover 22 and the casing 1, and the power cord 3 is wrapped around the portion of the air inlet grille 21 extending to the outside of the casing 1 through the gap 13 to achieve wrapping and storage, and the wrapped power cord 3 can be shielded by the air filter cover 22, thereby improving the storage aesthetics.

[0058] like Figure 2 , Figure 3 and Figure 7 As shown, the shape of the air inlet grille 21 is consistent with the shape of the air inlet 11, and can be circular, elliptical or geometric, etc. In this embodiment, based on the air inlet 11 being configured as a circle, the air inlet grille 21 is also configured as a circle and is snap-fitted to the inner wall of the air inlet 11 for fixation, but is not limited to this.

[0059] The air filter cover 22 is covered outside the air inlet grille 21 to protect the air inlet grille 21 so that the wind flows through the air filter cover 22 for primary filtering before flowing into the air inlet grille 21 .

[0060] like Figure 2 and Figure 4 As shown, the shape of the air filter cover 22 can be circular, elliptical or geometric, etc. In this embodiment, the air filter cover 22 is set to be square as an example for illustrative description. The square air filter cover 22 is consistent with the shape of the casing 1.

[0061] The air filter port 221 can be set as a grille port, and the air filter port 221 is connected to the air inlet grille 21, and its size can be designed according to needs. It should be noted here that the smaller the size of the air filter port 221 is set, the higher the degree of air filtering is.

[0062] It can be understood here that when the power cord 3 is wrapped around the outer periphery of the circular air inlet grille 21, the wrapped portion is limited by the square air filter cover 22 extending to the part outside the air inlet grille 21, preventing the wrapped power cord 3 from axially loosening from the air inlet grille 21, thereby ensuring the storage stability of the power cord 3.

[0063] In some embodiments, the size of the gap 13 is 12 mm-15 mm.

[0064] By setting the size of the gap 13 between the air filter cover 22 and the housing 1 within a suitable range, it is possible to prevent the power cord 3 from being easily loosened after being wound, and to prevent the gap 13 from being too large to affect the air intake of the heater.

[0065] Exemplarily, the size of the gap 13 may be 12 mm, 13 mm, 14 mm or 15 mm, which is not specifically limited in this embodiment.

[0066] It should be noted that, in the present embodiment, one side of the air filter cover 22 facing the casing 1 abuts against the air inlet grille 21, so the size of the gap 13 between the air filter cover 22 and the casing 1 is equal to the length of the portion of the air inlet grille 21 extending outside the casing 1. Therefore, the gap 13 between the air filter cover 22 and the casing 1 can be adjusted by controlling the length of the portion of the air inlet grille 21 extending outside the casing 1, and the present application does not impose any specific restrictions.

[0067] In some embodiments, the housing 1 is provided with a mounting hole 14 , and a connecting structure 223 is provided on a side of the air filter cover 22 facing the housing 1 , and the connecting structure 223 is assembled in the mounting hole 14 .

[0068] By setting a mounting hole 14 in the casing 1 and setting a connecting structure 223 on the side of the air filter cover 22 facing the casing 1, the connecting structure 223 is assembled in the mounting hole 14, so as to achieve the connection and fixation between the air filter cover 22 and the casing 1.

[0069] like Figure 2 and Figure 5 As shown, in terms of the number of settings, in some embodiments, a plurality of connection structures 223 are provided along the circumference of the air filter cover 22, a plurality of mounting holes 14 are provided along the circumference of the air inlet 11, and the plurality of connection structures 223 are assembled in a one-to-one correspondence to the plurality of mounting holes 14.

[0070] By assembling the plurality of connection structures 223 in a one-to-one correspondence with the plurality of mounting holes 14 , the air filter cover 22 and the housing 1 are connected and fixed at multiple locations, thereby enhancing the connection stability between the air filter cover 22 and the housing 1 .

[0071] In this embodiment, four connecting structures 223 are arranged along the circumference of the air filter cover 22, and four mounting holes 14 are arranged along the circumference of the air inlet 11. The four air filter covers 22 are assembled in the four mounting holes 14 one by one, thereby realizing the four-way connection and fixation between the air filter cover 22 and the casing 1, but it is not limited to this.

[0072] Furthermore, the four connection structures 223 are arranged at equal intervals along the circumference of the air filter cover 22 to improve the uniformity of the force applied to the circumference of the air filter cover 22 .

[0073] like Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments, the air filter cover 22 can rotate relative to the casing 1, and the mounting hole 14 is extended along the rotation trajectory of the air filter cover 22. The connecting structure 223 includes a connecting portion 2231 and a knob 2232. The connecting portion 2231 is fixedly connected to the side of the casing 1 toward the air filter cover 22, and the knob 2232 is fixed to the connecting portion 2231. The knob 2232 and the connecting portion 2231 are set at an angle. The knob 2232 can be inserted into the mounting hole 14 and the knob 2232 can rotate in the mounting hole 14 driven by the air filter cover 22 so that the knob 2232 is buckled onto the inner wall of the mounting hole 14.

[0074] During installation, first align the connecting structures 223 on the air filter cover 22 with the mounting holes 14 on the casing 1, insert the knobs 2232 of the connecting structures 223 into the mounting holes 14 through the air filter cover 22, and rotate the air filter cover 22 to make the knobs 2232 rotate in the mounting holes 14 so that the knobs 2232 are finally buckled onto the inner walls of the mounting holes 14, thereby achieving the snap-fit ​​locking of the knobs 2232 into the mounting holes 14, thereby achieving the connection and fixation between the air filter cover 22 and the casing 1, and due to the cooperation between the knobs 2232 and the inner walls of the mounting holes 14, the air filter cover 22 can be prevented from being loosened away from the casing 1, thereby ensuring the stability of the connection between the two.

[0075] Specifically, the mounting hole 14 is extended into an arc shape along the rotation trajectory of the air filter cover 22, the mounting hole 14 is communicated with the internal cavity of the casing 1, the connecting portion 2231 is extended perpendicular to the surface of the air filter cover 22, and the rotary buckle 2232 is designed to be perpendicular to the air filter cover 22. The rotation of the air filter cover 22 drives the rotary buckle 2232 to rotate along the arc-shaped mounting hole 14, and finally the rotary buckle 2232 is rotated into the internal cavity of the casing 1 and is buckled with the inner wall of the mounting hole 14 (that is, the cavity wall of the internal cavity of the casing 1) to prevent the air filter cover 22 from loosening.

[0076] In this embodiment, the knob 2232 and the connecting portion 2231 (i.e., the connecting structure 223) are L-shaped as a whole, and the length direction of the knob 2232 is consistent with the tangent direction of the rotation direction of the air filter cover 22, so that the knob 2232 can be rotated into the internal cavity of the housing 1 and the inner wall of the mounting hole 14 during the rotation of the air filter cover 22. In this embodiment, the air filter cover 22 rotates clockwise to drive the knob 2232 to be assembled with the housing 1 in the clockwise direction, but it is not limited thereto. For example, in other embodiments, the air filter cover 22 can also rotate counterclockwise to drive the knob 2232 to be assembled with the housing 1 in the counterclockwise direction.

[0077] In addition, in some embodiments, the knob 2232 and the connecting portion 2231 (i.e., the connecting structure 223) are overall in an inverted T-shaped structure. At this time, whether the air filter cover 22 rotates clockwise or counterclockwise, it can drive the inverted T-shaped connecting structure 223 to partially buckle onto the inner wall of the mounting hole 14.

[0078] One end of the power cord 3 extends into the internal cavity of the casing 1 and is connected to the heating part of the heater. The other end of the power cord 3 with a plug 31 passes through the wire hole 12 and is located outside the casing 1. It is used to connect to a power source to supply power to the heating part so that it is powered on and generates heat to achieve heating.

[0079] It should be noted that the wire hole 12 is arranged away from the air inlet 11 and the mounting hole 14 to avoid mutual interference. Specifically, the wire hole 12 can be arranged at any position on the housing 1 covered by the air filter cover 22, so that the wire hole 12 is not exposed, improving the appearance of the whole machine.

[0080] Optionally, the fixing structure may be provided on the air inlet assembly 2, in which case the plug 31 of the power cord 3 is fixed on the air inlet assembly 2 via the fixing structure;

[0081] Alternatively, the fixing structure may be provided on the housing 1, in which case the plug 31 of the power cord 3 is fixed to the housing 1 through the fixing structure;

[0082] Alternatively, the fixing structure may be provided on both the air inlet assembly 2 and the housing 1, and the plug 31 of the power cord 3 may be selectively fixed to the air inlet assembly 2 or the housing 1 through the fixing structure. In this embodiment, the fixing structure is provided on the air inlet assembly 2 as an example for schematic description, but it is not limited thereto.

[0083] In some embodiments, the fixing structure is a snap-fit ​​structure, and the snap-fit ​​structure is used to snap-fit ​​and fix the plug 31 .

[0084] The fixing structure is set as a clamping structure, and the plug 31 is clamped and fixed by the clamping structure, which is convenient and quick.

[0085] like Figure 4 and Figure 5As shown, in some embodiments, the snap-fit ​​structure is a snap-fit ​​slot 222 , and the plug 31 can be snap-fitted into the snap-fit ​​slot 222 .

[0086] The snap-fit ​​structure is arranged in the form of a snap-fit ​​slot 222 , and the plug 31 is snap-fitted into the snap-fit ​​slot 222 to be fixed. The structure is simple and the manufacturing cost is low.

[0087] In some embodiments, the slot 222 is a U-shaped slot, and the slot wall of the U-shaped slot is engaged with the outer wall of the plug 31 .

[0088] The card slot 222 is configured as a U-shaped slot, and the slot wall of the U-shaped slot engages with the outer wall of the plug 31 , which can increase the card connection area between the card slot 222 and the plug 31 , thereby enhancing the card connection stability.

[0089] In terms of the number of arrangements, in some embodiments, based on the arrangement of the fixed structure on the air inlet assembly 2 , at least two fixed structures are arranged at intervals along the circumference of the air inlet assembly 2 .

[0090] By arranging at least two fixing structures at circumferential intervals along the air inlet assembly 2, the plug 31 of the power cord 3 can be selectively fixed by one of the fixing structures after the power cord 3 is wound and stored, thereby increasing multiple fixing methods for easy use.

[0091] It is understandable that the remaining length of the plug 31 of the power cord 3 is different when the power cord 3 is wound around different numbers of times. Therefore, the plug 31 can be selectively fixed through one of the fixing structures according to the number of times the power cord 3 is wound around, thereby improving the convenience of use.

[0092] In some embodiments, at least two fixing structures are symmetrically distributed along the center of the air inlet assembly 2 .

[0093] By symmetrically distributing at least two fixing structures along the center of the air inlet assembly 2, the overall aesthetics of the heater can be improved.

[0094] In this embodiment, based on the fixed structure being set as a card slot 222, two card slots 222 are provided and are symmetrically arranged on opposite sides of the air filter cover 22. The plug 31 of the power cord 3 can be selectively card-connected and fixed in one of the card slots 222, but is not limited to this.

[0095] In this embodiment, the card slot 222 is set as a U-shaped slot, the slot opening of the U-shaped slot passes through the edge of the air filter cover 22, and the plug 31 of the power cord 3 is inserted into the U-shaped slot through the slot opening of the U-shaped slot to achieve card connection and fixation.

[0096] In addition to the above structure, in order to ensure the normal function of the heater, the housing 1 is also provided with an air outlet connected to the air inlet 11, so that the heated hot air can be discharged from the air outlet to achieve heating.

[0097] In addition, the heater also includes structures such as a fan and a heating part to ensure its normal operation. Since they are existing technologies, they will not be described in detail in this embodiment.

[0098] In order to facilitate the understanding of the heater of this embodiment, Figure 1 To Attachment Figure 8 , the following is an introduction to the assembly and use of the heater:

[0099] To assemble the heater, first install the heating part, fan and other structures in the internal cavity of the casing 1 in sequence, pass the end of the power cord 3 away from the plug 31 through the wire hole 12 to enter the internal cavity of the casing 1 and be electrically connected to the heating part, and the end of the power cord 3 with the plug 31 is located outside the casing 1, install the air inlet grille 21 at the air inlet 11, and control the length of the part of the air inlet grille 21 extending out of the casing 1 to be 12mm-15mm, align the connecting structure 223 on the air filter cover 22 with the mounting hole 14 on the casing 1, and insert the knob 2232 into the mounting hole 14, at this time, the air filter cover 22 and the air inlet grille 21 are abutted, rotate the air filter cover 22 to make the knob 2232 rotate in the mounting hole 14, and finally rotate the knob 2232 into the internal cavity of the casing 1 and buckle and fix it with the inner wall of the mounting hole 14, so as to realize the connection and locking of the air filter cover 22 and the casing 1.

[0100] To use the heater, connect the plug 31 of the power cord 3 to a power source and start the fan.
