Description

Technical Field

[0001] This utility model relates to the field of heater technology, and more specifically, it relates to an angle-adjustable heater. Background Technology

[0002] A warm air blower is a combined unit consisting of a fan, an electric motor, and an air heater. It is suitable for various types of workshops and everyday life scenarios. When the air does not contain dust or flammable or explosive gases, it can be used for circulating air heating. A warm air blower can be used independently for heating. It is generally used to supplement the insufficient part of the radiator or to use the radiator for standby heating. The remaining heat load is borne by the warm air blower.

[0003] In everyday life, most existing space heaters lack an oscillation function (similar to a fan). While this oscillation feature allows for rapid temperature increases and wider temperature coverage, the internal device driving the oscillation mechanism during this process generates vibration and sway. This is because uneven mass distribution in the rotor (rotating component) (e.g., manufacturing tolerances, assembly deviations) causes periodic changes in centrifugal force during rotation, resulting in vibration. This swaying is transmitted through the heater body to the base, easily causing the heater to tip over to one side due to vibration or swaying. Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heater with adjustable angle.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an angle-adjustable heater, including a heater housing, a base rotatably connected to the bottom of the heater housing, a heating element and a fan disposed inside the heater housing, a limit component disposed on the base, a oscillating component disposed on the limit component, and a stabilizing component disposed between the limit component and the oscillating component, the stabilizing component including a first rotating ring, a first protrusion, a second rotating ring, a reset post and a second protrusion, the first rotating ring and the first protrusion being fixedly connected to the bottom of the oscillating component, the reset post and the second protrusion being respectively fixed on the second rotating ring, the first protrusion on the first rotating ring contacting the second protrusion on the second rotating ring for slidingly connecting the reset post to the limit component.

[0006] By adopting the above technical solution, the first rotating ring and the first protrusion rotate and press the second protrusion on the second rotating ring, causing the second rotating ring to descend and drive the column of the reset column to slide in the hole. The spring of the reset column is compressed, thereby stabilizing the center of gravity shift that occurs during the oscillation of the heater housing, reducing the phenomenon of tipping over during oscillation, and improving the safety of using the heater.

[0007] The present invention is further configured such that: the limiting component includes a disc, the disc is fixedly connected to the base, the disc has a first arc-shaped groove, the first arc-shaped groove is slidably connected to the oscillating component, a fixing post is fixedly connected to the disc near the center, the fixing post is detachably connected to the oscillating component, the disc has holes, the holes are connected to the base, six sets of holes are respectively arranged along the center of the disc, and the first arc-shaped groove of the disc is in two sets and symmetrically arranged.

[0008] By adopting the above technical solution, the first arc groove can limit the movement of the oscillating assembly during rotation, and the disc can limit or slide the second rotating ring within the disc, thereby improving the stability of the oscillating assembly and the second rotating ring, and further enhancing the oscillating effect of the heater housing.

[0009] The present invention is further configured as follows: the oscillating assembly includes a chassis, the chassis and the base are rotatably connected at their center, a motor is fixedly connected to the chassis, a cam is fixedly connected to the output end of the motor, a swing rod is rotatably connected to the cam, a bolt is rotatably connected to the end of the swing rod away from the cam, the bolt is detachably connected to a fixed post, a limit post is fixedly connected to the bottom of the chassis, the limit post is set in a first arc groove and is slidably connected, a second arc groove is opened on the chassis, the second arc groove is used for the swing range of the chassis, the cam and the swing rod are connected by a pin, the swing rod is sleeved on the bolt, the edges of the first protrusion and the second rotating ring are both set with bevels, the column body and spring of the reset post are set in six groups along the center of the second rotating ring, and the six groups of reset posts are adapted to six groups of holes.

[0010] By adopting the above technical solution, the rotation of the cam and the swing rod causes the swing rod to swing, which in turn causes the chassis and the heater housing to swing and oscillate, allowing the hot air to cover a larger area. This avoids the problem of uneven indoor temperature caused by heating in one direction, allowing every corner of the room to enjoy warmth, and effectively improving the comfort and effect of heating.

[0011] The present invention is further configured such that: the first rotating ring is fixedly connected to the bottom of the chassis, two sets of first protrusions are fixed on the side of the first rotating ring away from the chassis, the reset post is disposed in the disc, the reset post is divided into a reset spring and a post body, the post body of the reset post is slidably connected to a hole on the disc, the reset post is fixedly connected to the bottom of the second rotating ring, and the second protrusion is fixedly connected to the top of the second rotating ring.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. Through the cooperation of cam, swing rod and bolt, the heater housing can swing continuously. The swinging motion allows the heater's air outlet to change direction within a certain angle range, so that the hot air can cover a larger area. This avoids the problem of uneven indoor temperature caused by heating in one direction, allowing every corner of the room to enjoy warmth, and effectively improving the comfort and effect of heating.

[0014] 2. Through the cooperation of the first rotating ring, the first protrusion, the second rotating ring, the reset post, and the second protrusion, the first protrusion will abut against the second protrusion when the heater housing is not oscillating, thereby limiting the direction after oscillation. At the same time, the post in the reset post can be continuously extended into the hole, thereby stabilizing the center of gravity shift that occurs during the oscillation of the heater housing, reducing the phenomenon of tipping over during oscillation, and improving the safety of using the heater.

[0023] Please refer to the embodiments of this utility model. Figures 1 to 7 An angle-adjustable heater includes a heater housing 1, a base 11 rotatably connected to the bottom of the heater housing 1, a heating element and a fan disposed inside the heater housing 1, a limit component 2 disposed on the base 11, an oscillating component 3 disposed on the limit component 2, and a stabilizing component 4 disposed between the limit component 2 and the oscillating component 3. The stabilizing component 4 includes a first rotating ring 41, a first protrusion 42, a second rotating ring 43, a reset post 44 and a second protrusion 45. The first rotating ring 41 and the first protrusion 42 are fixedly connected to the bottom of the oscillating component 3, the reset post 44 and the second protrusion 45 are respectively fixed on the second rotating ring 43, and the first protrusion 42 on the first rotating ring 41 contacts the second protrusion 45 on the second rotating ring 43 to slide the reset post 44 on the limit component 2.

[0024] The following discloses the structural features of the limiting component 2. Please refer to it. Figure 3 and Figure 6 The limiting component 2 includes a disc 21, which is fixedly connected to the base 11. The disc 21 has a first arc-shaped groove 22, which is slidably connected to the oscillating component 3. A fixing post 23 is fixedly connected to the disc 21 near the center, and the fixing post 23 is detachably connected to the oscillating component 3. The disc 21 has holes 24, which are connected to the base 11. There are six sets of holes 24 along the center of the disc 21. The disc 21 has two sets of first arc-shaped grooves 22, which are symmetrically arranged. In this embodiment, the edge of the disc 21 is hollowed out, and the fixing post 23 on the disc 21 has threads inside to facilitate the connection of the bolts 35. The holes 24 on the disc 21 are through-holes and are also connected to the base 11, which means that the base 11 also has the same holes 24. The two sets of first arc-shaped grooves 22 are provided to provide the range of oscillation for the oscillating component 3.

[0025] The detailed structure of the head-shaking component 3 is disclosed below. Please refer to it. Figure 3 and Figure 5The oscillating assembly 3 includes a chassis 31, which is rotatably connected to the center of the base 11. A motor 32 is fixedly connected to the chassis 31, and a cam 33 is fixedly connected to the output end of the motor 32. A swing rod 34 is rotatably connected to the cam 33, and a bolt 35 is rotatably connected to the end of the swing rod 34 away from the cam 33. The bolt 35 is detachably connected to the fixed post 23. A limit post 37 is fixedly connected to the bottom of the chassis 31. The limit post 37 is set in the first arc groove 22 and is slidably connected. A second arc groove 36 is opened on the chassis 31. The second arc groove 36 is used to determine the swing range of the chassis 31. The cam 33 and the swing rod 34 are connected by a pin. The swing rod 34 is sleeved on the bolt 35. In this embodiment, the arrangement of the motor 32, cam 33, swing rod 34 and bolt 35 causes the cam 33 and the swing rod 34 to swing continuously, thereby driving the chassis 31 and the heater housing 1 to swing synchronously. This structure is similar to the oscillating fan mechanism.

[0026] The detailed structure of stable component 4 is disclosed below. Please refer to it. Figure 4 , Figure 6 and Figure 7 The first rotating ring 41 is fixedly connected to the bottom of the chassis 31. Two sets of first protrusions 42 are fixed to the side of the first rotating ring 41 away from the chassis 31. The reset post 44 is set in the disc 21. The reset post 44 consists of a reset spring and a post body. The post body of the reset post 44 is slidably connected to the hole 24 on the disc 21. The reset post 44 is fixedly connected to the bottom of the second rotating ring 43. The second protrusion 45 is fixedly connected to the top of the second rotating ring 43. The edges of the first protrusion 42 and the second rotating ring 43 are both set with bevels. The post body of the reset post 44... The body and spring are arranged in six groups along the center of the second rotating ring 43. The six groups of reset posts 44 are adapted to the six groups of holes 24. In this embodiment, the first protrusion 42 on the first rotating ring 41 and the second protrusion 45 on the second rotating ring 43 are attached to each other, so that the first protrusion 42 will stably squeeze the second protrusion 45 during the rotation of the first protrusion 42, thereby compressing the spring on the reset post 44 and making the post on the reset post 44 more stably inserted into the hole 24, preventing the base 11 from having instability during the oscillation of the heater housing 1.

[0027] Working principle: First, the staff moves the device to the designated location. Then, the staff turns the knob on the heater housing 1 to start the fan and heating element in the heater housing 1. Next, when the staff needs to activate the oscillation function, they need to turn another knob on the heater housing 1 to start the motor 32. This causes the cam 33 fixed at the output end of the motor 32 to rotate. Since the bolt 35 is fixedly connected to the fixed column 23, the rotation of the cam 33 drives the swing rod 34 to swing around the center of the bolt 35. Since the motor 32 is fixedly connected to the chassis 31, the swing force of the cam 33 and the swing rod 34 will drive the chassis 31 to swing around the center. The swing of the chassis 31 will synchronously drive the heater housing 1 to rotate, thereby realizing the normal oscillation function of the heater housing 1. This allows the air outlet of the heater to continuously change direction within a certain angle range.

[0028] Since the second rotating ring 43, the reset post 44, and the second protrusion 45 are disposed in the disk 21, when the chassis 31 rotates, it will drive the first rotating ring 41 and the first protrusion 42 to rotate synchronously. When the first rotating ring 41 and the first protrusion 42 rotate, the first protrusion 42 on the first rotating ring 41 will contact and press with the second protrusion 45 on the second rotating ring 43, causing the second rotating ring 43 to move downward as a whole. Since the post in the reset post 44 is disposed in the hole 24 on the disk 21, the second rotating ring 43 moves downward. When lowered, the column on the reset post 44 will continue to slide in the hole 24, which is connected to the base 11. Therefore, the reset post 44 on the hole 24 will continue to slide and slide inside the base 11 until it abuts against the bottom of the base 11. At this time, the spring on the reset post 44 will become compressed, which facilitates the reset of the column in the reset post 44. This design can stabilize the center of gravity shift that occurs during the oscillation of the heater housing 1, reduce the phenomenon of tipping over when oscillating, and improve the safety of using the heater.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
