Description

Technical Field

[0001] This invention relates to the field of electric heater technology, specifically to an oil-filled radiator. Background Technology

[0002] Currently, traditional electric heaters can be categorized into oil-filled radiators, fan heaters, and far-infrared heaters. Each type has its own characteristics and is suitable for different environments. However, the primary function of electric heaters is to raise the indoor temperature; therefore, their heating efficiency and heating effect directly determine their quality. Oil-filled radiators are among the most efficient traditional electric heaters and are currently a primary means of solving whole-house heating problems. Traditional oil-filled radiators are characterized by stable heating and high temperatures. However, they also have drawbacks: once the radiator fins heat up, users can easily touch the surface, posing a certain safety hazard. Therefore, safety standards often limit the temperature of the radiator fins, preventing the product from fully realizing its performance and limiting its heating capabilities.

[0003] To address the issue of burns caused by users touching the radiator when it overheats, a grille cover is added to the oil-filled radiator body. This prevents users from directly touching the radiator and getting burned. However, the traditional approach of adding a grille cover often only increases the product's heating power. Although the overall heating effect increases, the high temperature inside the grille is not easily dissipated, causing the unit to not reach its maximum performance, resulting in poor heating effect and, over time, overheating safety issues. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the heat inside the grid is not easily transferred out after adding grid to the oil radiator body, resulting in poor heating effect, thereby providing an oil radiator electric heater.

[0005] To address the aforementioned problems, the present invention provides an oil-filled radiator, comprising: an oil-filled radiator body; a first grille disposed on one side of the oil-filled radiator body; and a fan installed between the first grille and the oil-filled radiator body, the fan having an operating state and a stopped state for accelerating heat transfer within the oil-filled radiator body.

[0006] Optionally, the fan is positioned near the top of the oil-filled radiator body, and the bottom side of the first grille is rotatably positioned on one side of the oil-filled radiator body. The first grille has a first unfolded state that swings outward at a preset angle relative to the oil-filled radiator body and a first retracted state that is close to the oil-filled radiator body.

[0007] Optionally, the oil-filled radiator also includes a wing-shaped fan, which includes a swing base and a fan. The swing base has mounting holes extending through its two opposite surfaces, and the fan is mounted in the mounting holes. The swing base is rotatably mounted on the first grille or the oil-filled radiator body. The wing-shaped fan has a second deployed state with its first side away from the oil-filled radiator body and a second retracted state with its first side close to the oil-filled radiator body. When the first grille is in the first deployed state and the wing-shaped fan is in the second deployed state, the swing base is supported between the first grille and the oil-filled radiator body.

[0008] Optionally, the oil-filled radiator also includes a drive unit, which is disposed on the first grille or the oil-filled radiator body. The drive unit has a drive end, which is rotatably connected to the swing seat to drive the wing fan to switch from a second retracted state to a second extended state.

[0009] Optionally, the drive unit includes a fixed seat, an elastic element, a first rod, and a second rod. The fixed seat has a blind mounting hole, the elastic element is installed in the blind mounting hole, one end of the first rod extends into the blind mounting hole and abuts against the elastic element, the other end of the first rod is hinged to one end of the second rod, and the other end of the second rod is hinged to the swing seat; or, the drive unit is a drive cylinder, the cylinder barrel of the drive cylinder is hinged to the first grille or oil heater body, and the piston rod of the drive cylinder is hinged to the swing seat.

[0010] Optionally, there are two first grilles and two wing fans, which are set in a one-to-one correspondence. The two first grilles are located on the left and right sides of the oil heater body, and at least one fan is installed on each swing seat.

[0011] Optionally, the oil-filled radiator also includes four second grilles. The oil-filled radiator body is provided with second grilles on the left and right sides at both ends along its length. The four second grilles are arranged in pairs. The bottom side of one first grille is hinged to a pair of second grilles, and the bottom side of another first grille is hinged to another pair of second grilles.

[0012] Optionally, when the swing seat is rotatably mounted on the first grid, the first side of the swing seat is hinged to the first grid, and the second side of the swing seat can swing toward the oil heater body. The second grid is provided with a first limiting member, and the second side of the swing seat is provided with a second limiting member. When the wing fan is in the second deployed state, the second limiting member cooperates with the first limiting member to limit the position of the swing seat and the first grid.

[0013] Optionally, the swing seat is equipped with a magnetic component, which is attracted to the oil heater body when the wing fan is in the second retracted state.

[0014] Optionally, the swing seat has a groove, and a first hinge shaft is provided in the groove. The drive end of the drive unit is sleeved on the first hinge shaft.

[0015] The present invention has the following advantages:

[0016] 1. A fan is installed between the first grille and the oil heater body. When the fan is turned on, forced air convection is performed, which can transfer the heat in the first grille out, enhance the heat transfer rate, improve the heating effect, shorten the heating time, and improve the user experience. In addition, the first grille can protect the user and reduce the risk of burns from direct contact with the radiator.

[0017] 2. The initial state of the first grille is the first retracted state. After rotating the first grille outward by a preset angle to the first unfolded state, the oil-filled radiator is in the shape of an inverted trapezoid that is wider at the top and narrower at the bottom. Then, the fan is turned on. The high heat generated in the narrow space at the bottom will flow upward due to the pressure difference, thus achieving the effect of heat accumulation. When the fan runs at the top to absorb heat, it will also drive the air to circulate upward. In addition, the upper space is wider, and the air volume blown out by the fan will cover a wider range, further enhancing the heat transfer rate, enhancing the overall heating effect of the unit, and further shortening the heating time of the whole room.

[0018] 3. The initial state of the first grille is the first retracted state, and the initial state of the wing-shaped fan is the second retracted state. When opening the wing-shaped fan, first rotate the first grille outward by a preset angle to the first deployed state, then swing the swing seat towards the oil heater body until the wing-shaped fan is in the second deployed state. The swing seat is supported between the first grille and the oil heater body. At this time, the oil heater is in the shape of an inverted trapezoid, wider at the top and narrower at the bottom. Then, start the fan. When the oil heater is operating at full power, the high heat generated in the narrow space at the bottom will flow upward due to the pressure difference, thus achieving the effect of heat concentration. When the fan runs at the top to absorb heat, it will also drive the air upward. In addition, the upper space is wider, and the air volume blown by the fan will cover a wider range, which will enhance the heat transfer rate, improve the overall heating effect, and shorten the heating time of the whole house. When storing or hiding the wing fan, first swing the swing seat toward the first grille until the wing fan is attached to the first grille, and then rotate the first grille toward the oil heater body to the first storage state, which can store or hide the wing fan. At this time, the fan can be started or stopped as needed. When the fan is not started, the whole unit will have natural convection. When the fan is started, the whole unit will have local forced convection. The whole unit has more diversified usage modes to meet various user needs.

[0019] 4. The state of the wing fan is switched by the drive unit, eliminating the need for manual operation of the swing seat, making it easier for users to operate. In addition, the drive unit also serves to support the swing seat. Attached Figure Description

[0045] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0048] Furthermore, 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.

[0049] like Figures 1 to 5 As shown, the oil-filled radiator of this embodiment includes: an oil-filled radiator body 10, a first grille 20, and a fan 40. The first grille 20 is disposed on one side of the oil-filled radiator body 10. The fan 40 is installed between the first grille 20 and the oil-filled radiator body 10. The fan 40 has a working state and a stopped state to accelerate the heat transfer of the oil-filled radiator body 10.

[0050] In the oil-filled radiator of this embodiment, a fan 40 is installed between the first grille 20 and the oil-filled radiator body 10. When the fan 40 is turned on, forced convection is performed on the air, which can transfer the heat in the first grille 20 out, enhance the heat transfer rate, improve the heating effect, shorten the heating time, and improve the user experience. In addition, the first grille 20 can protect the user and reduce the risk of burns caused by the user directly touching the radiator.

[0051] In this embodiment, as Figure 6 and Figure 7As shown, the fan 40 is positioned near the top of the oil-filled radiator body 10, and the bottom side of the first grille 20 is rotatably mounted on one side of the oil-filled radiator body 10. The first grille 20 has a first extended state, swinging outward at a preset angle relative to the oil-filled radiator body 10, and a first retracted state, close to the oil-filled radiator body 10. It should be noted that the preset angle is less than 90 degrees. The initial state of the first grille 20 is the first retracted state. After rotating the first grille 20 outward at a preset angle to the first extended state, the oil-filled radiator is in an inverted trapezoidal shape, wider at the top and narrower at the bottom. Then, the fan 40 is turned on. The high heat generated in the narrow space at the bottom will flow upward due to the pressure difference, thus achieving a heat-gathering effect. When the fan 40 operates at the top to absorb heat, it will also drive the air upward. In addition, the upper space is wider, and the airflow blown by the fan will cover a wider range, further enhancing the heat transfer rate, improving the overall heating effect of the unit, and further shortening the heating time of the whole room.

[0052] In this embodiment, as Figure 12 , Figure 13 and Figure 19 As shown, the fan 40 includes a rotor 41, a first shield 42, and a second shield 43. The first shield 42 and the second shield 43 are disposed on both sides of the rotor 41. The first shield 42 and the second shield 43 provide safety protection to prevent accidental contact or falling debris during the operation of the rotor 41. Preferably, the first shield 42 and the second shield 43 are both radial shields, and the rotor 41 is a DC rotor.

[0053] Specifically, each swing seat 30 is equipped with three fans 40. It can be understood that the number of fans 40 can also be two or four, etc., and is not limited to this.

[0054] In this embodiment, as Figure 6 , Figure 7 , Figure 12 , Figure 17 and Figure 18As shown, the oil-filled radiator also includes a wing-shaped fan, which comprises a swing base 30 and a fan 40. The swing base 30 has mounting holes 31 extending through its two opposing surfaces. The fan 40 is mounted in the mounting holes 31. A first side of the swing base 30 is rotatably mounted on a first grille 20. The wing-shaped fan has a second extended state with its first side away from the oil-filled radiator body 10 and a second retracted state with its first side close to the oil-filled radiator body 10. When the first grille 20 is in the first extended state and the wing-shaped fan is in the second extended state, the swing base 30 is supported between the first grille 20 and the oil-filled radiator body 10. One end of the mounting hole 31 forms an air inlet, and the other end of the mounting hole 31 forms an air outlet. The first grille 20 is initially in its first retracted state, and the wing-shaped fan is initially in its second retracted state. When the wing-shaped fan is opened, the first grille 20 is first rotated outward by a preset angle to the first open state. Then, the swing seat 30 is swung towards the oil heater body 10 until the wing-shaped fan is in the second open state. The swing seat 30 is supported between the first grille 20 and the oil heater body 10. At this time, the oil heater is in the shape of an inverted trapezoid, wider at the top and narrower at the bottom. Then, the fan 40 is started. When the oil heater is operating at full power, the high heat generated in the narrow space at the bottom will flow upward due to the pressure difference, thus achieving the effect of heat concentration. When the fan 40 is running at the top and absorbing heat, it will also drive the air upward. In addition, the upper space is wider, and the air volume blown by the fan will cover a wider range, which will enhance the heat transfer rate, enhance the heating effect of the whole unit, and shorten the heating time of the whole house. When storing or hiding the wing fan, first swing the swing seat 30 toward the first grille 20 until the wing fan is attached to the first grille 20, and then rotate the first grille 20 toward the oil heater body 10 to the first storage state, so that the wing fan can be stored or hidden. At this time, the fan 40 can be started or not started as needed. When the fan 40 is not started, the whole unit will have natural convection. When the fan 40 is started, the whole unit will have local forced convection. The usage mode of the whole unit is more diversified to meet the various needs of users.

[0055] It is understood that, as an alternative implementation, the swing seat 30 is not provided, the fan 40 is fixed on the first grille 20, or the fan is fixed on the oil heater body 10, in which case only the first grille 20 can be unfolded.

[0056] It is understood that, as an alternative implementation, the swing seat 30 is rotatably mounted on the oil heater body 10, the second side of the swing seat 30 is hinged to the oil heater body 10, and the first side of the swing seat 30 can swing toward the first grille 20. When the wing fan is in the second unfolded state, the first side of the swing seat 30 is connected to the first grille 20, so that the swing seat 30 and the first grille 20 can always be in the unfolded state. For example, the first side of the swing seat 30 and the first grille 20 are connected by a detachable connection method such as snap-fit.

[0057] Specifically, the swing seat 30 has a plate-like structure. When the wing-shaped fan is in its second unfolded state, the swing seat 30 is horizontally positioned, with the axis of the mounting hole 31 aligned vertically or along the height of the oil heater body 10. When the wing-shaped fan is in its second retracted state, the swing seat 30 is positioned along the height of the oil heater body 10, with the axis of the mounting hole 31 aligned horizontally. The swing seat 30 has a simple structure, making it easy to manufacture. When the wing-shaped fan is open, the oil heater appears neater and more aesthetically pleasing. It is understandable that the swing seat 30 is not limited to a plate-like structure; any structure that allows the fan 40 to swing is acceptable, such as a U-shaped structure.

[0058] It is understood that, as an alternative implementation, when the wing fan is in the second deployed state, the swing seat 30 is tilted at a certain angle relative to the horizontal.

[0059] In this embodiment, as Figure 3 , Figure 5 , Figure 7 , Figure 13 and Figures 20 to 22 As shown, the oil-filled radiator also includes a drive unit 50, which is mounted on the first grille 20 or the oil-filled radiator body 10. The drive unit 50 has a drive end, which is rotatably connected to the swing base 30 to drive the wing fan to switch from a second retracted state to a second extended state. Switching the state of the wing fan via the drive unit 50 eliminates the need for manual operation of the swing base 30, making it more convenient for users. Furthermore, the drive unit 50 also serves to support the swing base 30.

[0060] It is understood that, as an alternative implementation, the drive unit 50 may be omitted. When the wing fan is in the second deployed state, the second side of the swing seat 30 is connected to the oil heater body 10 or the second grille 60, which can keep the wing fan and the first grille 20 in the deployed state. For example, the second side of the swing seat 30 is connected to the oil heater body 10 or the second grille 60 by a detachable connection method such as a snap-fit. It should be noted that the second grille 60 will be described in detail later and will not be elaborated on here.

[0061] In this embodiment, the drive unit 50 includes a fixed base 51, an elastic element 52, a first rod 53, and a second rod 54. The fixed base 51 has a blind mounting hole, the elastic element 52 is installed in the blind mounting hole, one end of the first rod 53 extends into the blind mounting hole and abuts against the elastic element 52, the other end of the first rod 53 is hinged to one end of the second rod 54, and the other end of the second rod 54 is hinged to the swing seat 30. After the first grille 20 is unfolded, the elastic force of the elastic element 52 drives the swing seat 30 to swing toward the oil heater body 10. When the user operates, they only need to open the first grille 20, making the operation simple and effortless. The fixed base 51 is a fixed cylinder with one end open and one end closed, and the elastic element 52 is a spring, elastic sleeve, or elastic column, etc.

[0062] Specifically, the first grille 20 has a fixing buckle on the side facing the oil heater body 10 to lock the fixing seat 51. The fixing buckle has a slot facing the opening of the oil heater body, and the fixing seat 51 is locked in the slot. Figures 14 to 16 As shown, the fixing buckle includes a lower buckle 23 and an upper buckle 24, which are spaced apart vertically. The inner wall of the buckle opening is arc-shaped. The bottom of the lower buckle 23 has a sealing plate. The lower end of the fixing seat 51 is inserted into the lower buckle 23 and supported on the sealing plate. The sealing plate is used to limit the position of the lower end of the fixing seat 51 and prevent the fixing seat 51 from moving under the action of the elastic element. It can be understood that the fixing seat 51 can also be fixed to the first grille 20 by a detachable connection method such as screws.

[0063] It is understood that, as an alternative implementation, the drive unit 50 is a drive cylinder, the cylinder barrel of which is hinged to the first grille 20 or the oil heater body 10, and the piston rod of which is hinged to the swing seat 30. The drive cylinder is an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder, etc. In this case, an operation button or operation key is provided on the oil heater body 10. The drive cylinder is controlled to move by pressing the operation button or rotating the operation key. Similarly, the swing of the first grille 20 can also be achieved by a motor or a drive cylinder, for example, the motor is a rotary motor or a linear motor, and the drive cylinder is an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder, etc., which will not be described in detail here.

[0064] In this embodiment, as Figure 1 and Figure 6 As shown, there are two first grilles 20 and two corresponding wing-shaped fans. The two first grilles 20 are located on the left and right sides of the oil-filled radiator body 10, and at least one fan 40 is installed on each swing seat 30. Having wing-shaped fans on both the left and right sides of the oil-filled radiator body 10 improves forced convection, further enhancing the heating effect of the oil-filled radiator, increasing the overall heating efficiency of the house, and improving the user experience. It is understood that wing-shaped fans could also be installed only on the left or right side of the oil-filled radiator body 10.

[0065] Specifically, each wing-shaped fan is driven by two drive units 50, making the movement of the swing seat 30 more stable. It can be understood that the number of drive units can also be three, etc., depending on the requirements for rotating the number of drive units 50.

[0066] In this embodiment, as Figure 1 and Figure 5As shown, the oil-filled radiator also includes four second grilles 60. The oil-filled radiator body 10 has second grilles 60 on both the left and right sides at both ends along its length. The four second grilles 60 form pairs, with the bottom side of one first grille 20 hinged to one pair of second grilles 60, and the bottom side of another first grille 20 hinged to another pair of second grilles 60. Each pair of second grilles 60 is a front grille and a rear grille, which can also be called side grilles. The front and rear grilles facilitate fixing the left and right grilles. The space enclosed by the side, front, and rear grilles houses the wing-shaped fan and drive unit, making it easier to conceal the wing-shaped fan and drive unit, resulting in a more aesthetically pleasing overall appearance of the oil-filled radiator.

[0067] It should be noted that left and right refer to Figure 3 The directions indicated by the middle arrows, "left" and "right," and "forward" and "backward," refer to... Figure 4 The direction indicated by the middle arrow: "forward" or "backward".

[0068] In this embodiment, as Figures 8 to 11 As shown, the first side of the swing seat 30 is hinged to the first grille 20, and the second side of the swing seat 30 can swing towards the oil heater body 10. The second grille 60 is provided with a first limiting member 61, and the second side of the swing seat 30 is provided with a second limiting member 33. When the wing fan is in the second deployed state, the second limiting member 33 cooperates with the first limiting member 61 to limit the position of the swing seat 30 and the first grille 20, which can ensure that the wing fan will not shift to the sides after it is opened. Specifically, the first limiting member 61 is a limiting rod in the shape of an inverted L, and the second limiting member 33 is a limiting piece in the shape of a U. The second limiting member 33 and the side of the second side of the swing seat 30 form a limiting hole. When the wing fan is in the second deployed state, the vertical section of the first limiting member 61 is inserted into the limiting hole. It is understood that, as an alternative implementation, the first limiting member 61 is a U-shaped limiting piece, which, together with the second grille, forms a limiting hole. The second limiting member 33 is an L-shaped limiting rod, and when the wing-shaped fan is in the second deployed state, the vertical section of the second limiting member 33 is inserted into the limiting hole. It is understood that the structure of the first limiting member 61 and the second limiting member 33 is not limited to these; any structure that can limit the position of the swing seat 30 and the first grille 20 is acceptable.

[0069] It is understood that, as an alternative implementation, the second side of the swing seat 30 is rotatably mounted on the oil heater body 10, and the first side of the swing seat 30 can swing toward the first grille 20. When the wing fan is in the second unfolded state, the first side of the swing seat 30 is connected to the first grille 20, so that the swing seat 30 and the first grille 20 can always be in the unfolded state. For example, the first side of the swing seat 30 and the first grille 20 are connected by a detachable connection method such as snap-fit.

[0070] In this embodiment, the swing seat 30 is equipped with a magnetic component (not shown in the figure). When the wing-shaped fan is in the second retracted state, the magnetic component is attracted to the oil heater body 10. The magnetic component ensures the stability of the wing-shaped fan when it is in the retracted state. Specifically, the swing seat 30 has a first surface and a second surface. When the wing-shaped fan is in the second retracted state, the first surface is in contact with the oil heater body 10, the second surface is in contact with the first grille 20, and the magnetic component is disposed on the first surface. The magnetic component is preferably a magnet or the like.

[0071] In this embodiment, as Figure 17 , Figure 18 and Figure 20 As shown, a groove 35 is provided on the swing seat 30, and a first hinge shaft 32 is provided in the groove 35. The driving end of the drive unit 50 is sleeved on the first hinge shaft 32. The groove 35 is provided on the second surface, extends along the width direction of the swing seat 30, and one end of the groove 35 extends to the side of the second side. When the wing fan is retracted, part of the second rod 54 of the drive unit 50 is located in the groove 35. The setting of the groove 35 ensures that the second rod 54 swings normally.

[0072] In this embodiment, as Figures 14 to 17 As shown, the first side of the swing seat 30 is provided with a second hinge shaft 34, and the first grille 20 is provided with an arc-shaped hook 22. The second hinge shaft 34 is located in the arc-shaped hook 22. When assembling the swing seat 30, the second hinge shaft 34 is directly inserted into the arc-shaped hook 22, making assembly simple and efficient. Specifically, the hook opening of the arc-shaped hook 22 is set upwards. It can be understood that the hook opening of the arc-shaped hook 22 can also be set towards the oil heater body 10.

[0073] Specifically, the bottom side of the first grille 20 is provided with a third hinge shaft 21, and the second grille 60 is provided with a hinge hole, into which the third hinge shaft 21 is inserted.

[0074] It should be noted that the specific structure of the above-mentioned hinged or rotating connection is not limited to this; any structure that can achieve hinged connection is acceptable.

[0075] The following is combined with Figures 1 to 12 Instructions for using oil-filled radiators:

[0076] The initial state of the first grille 20 is the first retracted state, and the initial state of the wing fan is the second retracted state.

[0077] When the wing fan is opened, first rotate the first grille 20 outward by a preset angle to the first unfolded state, then swing the swing seat 30 toward the oil heater body 10 until the wing fan is in the second unfolded state. At this time, the oil heater is in an inverted trapezoid shape that is wider at the top and narrower at the bottom. Then start the fan 40. The fan 40 rotates at full speed and the airflow flows upward, thereby taking away the temperature on the fins and achieving forced convection.

[0078] When storing or hiding the wing fan, first swing the swing seat 30 toward the first grille 20 until the wing fan is attached to the first grille 20, then rotate the first grille 20 toward the oil heater body 10 to the first storage state, which can store or hide the wing fan. At this time, the fan 40 can be opened and closed as needed. When the fan 40 is closed, the whole machine undergoes natural convection heat dissipation. When the fan 40 is open, the whole machine undergoes local forced convection.

[0079] The design of the wing-shaped fan allows for adjustment of heating intensity without taking up space, enhancing the heat transfer rate and shortening the heating time of the whole house. By adding a fan, the oil-filled radiator can switch freely between natural convection and forced convection, which can solve the safety problems caused by excessive temperature of the oil-filled radiator fins, while improving the heating effect of the oil-filled radiator, increasing the heating efficiency of the whole house, and improving the user experience.

[0080] The assembly process of the oil-filled radiator is as follows: Place the fixed base 51 vertically and place the spring inside the fixed base 51. Then, install the lower end of the first rod 53 into the fixed base 51 and press it onto the spring. The lower end of the second rod 54 is hinged to the upper end of the first rod 53. Install the radiant face shield on one side of the swing base 30, with that side facing down and placed horizontally. Install the DC fan into the mounting hole of the swing base 30, and then install the radiant face shield. Place the oil-filled radiator body 10 vertically. Install the front and rear grilles on the first and rear sections of the oil-filled radiator body 10. Install the two side grilles on the front and rear grilles of the oil-filled radiator body. Install the fixed base 51 on the side grilles. Install the wing fan on the side grilles and connect it to the second rod 54 to complete the overall assembly.

[0081] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0082] 1. The oil-filled radiator includes the radiator body 10, 2 side grilles, 2 front grilles, 2 rear grilles, 12 radiant covers, 6 DC impellers, 2 swing seats 30, 4 second rods 54, 4 first rods 53, 4 fixed seats 51, and 4 springs. When the wing fan is turned on, forced convection is increased, carrying away the heat inside the grilles. This ensures safety by preventing overheating and also accelerates the temperature rise of the space. Using the grilles not only increases the heating effect but also protects the user from burns.

[0083] 2. The wing fan uses multiple DC impellers to drive airflow and achieve forced convection. Radial shields are installed on both sides of the impellers to provide safety protection and prevent accidental contact or falling debris during operation.

[0084] 3. A linkage mechanism is formed by the fixed seat 51, the spring, the first rod 53, and the second rod 54. When the wing fan is in the retracted state, the spring is in the contracted state. When the wing fan needs to be deployed, simply pull the side grille outward. At this time, the second rod 54 and the side grille will form a certain angle. Since the second rod 54 is a two-force member, the spring will automatically push the first rod 53 outward due to Hooke's law. At this time, the linkage mechanism forms a swing arm slider mechanism. Under the action of the elastic force of the spring, the swing seat 30 will be slowly pushed until the swing seat 30 is placed horizontally, realizing the automatic deployment of the wing fan and its stable operation in the deployed state. The deployment and retraction of the wing fan are more convenient, and the stability of the wing fan is strong. The high speed of the fan will not cause abnormal noise of the whole machine.

[0085] 4. The combined grille, consisting of two front grilles, two rear grilles, and two side grilles, protects users from burns when they come into contact with the oil heater. At the same time, the wing-shaped fan achieves forced convection, enhancing the heat transfer rate, reducing the heating time of the whole room, and thus increasing the product's heating power and enhancing the overall heating effect.

[0086] 5. The fan can be stored and deployed through a linkage mechanism, a combined grille, and a swing seat 30. The storage of the wing fan can save space and can be customized according to the usage environment to meet various conditions.

[0087] 6. When the wing fan is extended, the oil-filled radiator takes the shape of an inverted trapezoid, that is, wider at the top and narrower at the bottom. When the oil-filled radiator is working at full power, the air outlet area increases and the heating area is wider. The narrowed bottom further concentrates heat, providing sufficient and stable heat, laying the foundation for forced heating operation.

[0088] 7. The swing seat 30 is provided with a limiting hole, and the front and rear grilles are provided with inverted L-shaped limiting rods. After the wing fan is fully deployed, the limiting rods are inserted into the limiting holes to ensure that the swing seat 30 will not shift to the sides after it is opened.

[0089] 8. A magnet is provided on the swing seat 30, and when the wing fan is stored, the magnet attracts the oil heater body 10, ensuring the stability of the wing fan when it is stored.

[0090] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
