Through the combined action of the return spring, the telescopic rod, and the telescopic groove, the telescopic component can be pressed into the frame during heating element installation, making it easy to install the insulating heads and wiring heads at both ends of the heating element onto the telescopic component. This makes the installation process simple and convenient, less likely to damage the heating element, and has excellent practical performance.

[0005] However, the heating element has a complex structure, high production cost, and is easily damaged. Utility Model Content

[0006] In order to solve the above-mentioned problems in the prior art, this utility model provides a lamp tube snap-fit ​​heater.

[0007] The above-mentioned problems of this utility model are solved by the following technical solution:

[0008] A lamp tube snap-on heater, comprising,

[0009] The outer casing has a first heating zone and a second heating zone, which are connected inside the casing; the first heating zone and the second heating zone have different radiation directions.

[0010] The reflector is located inside the first heating zone and immediately adjacent to the back of the outer casing;

[0011] The light tube is located inside the first heating zone;

[0012] The housing is provided with an installation plate that penetrates the first heating zone and the second heating zone, and the lamp tube passes through the installation plate;

[0013] The mounting plate has a clip on its outer side to constrain the lamp tube axially.

[0014] A further provision of the above technical solution is that the main body of the card is U-shaped, and the two ends of the lamp tube can be inserted into the notch of the main body;

[0015] The lamp tube is provided with a slot that allows the two pins of the card to be engaged.

[0016] A further provision of the above technical solution is that: both ends of the lamp tube are provided with connecting joints with a diameter larger than that of the lamp tube, and the slot is provided on the connecting joint.

[0017] A further provision of the above technical solution is that a limiting buckle is provided on the outer end face of the mounting plate, the limiting buckle causing the card to be tightly attached to the end face of the mounting plate.

[0018] A further provision of the above technical solution is that at least two limit buckles are provided and arranged on the upper and lower sides of the lamp tube along the radial direction.

[0019] A further provision of the above technical solution is that the mounting plate is also provided with a limiting protrusion, which is disposed on the moving path of the card and is used to stop the card from exiting.

[0020] A further provision of the above technical solution is that the upper end of the mounting plate extends above the first heating area and combines with the top plate of the first heating area to form a second heating area;

[0021] An air outlet slot is provided on the top plate.

[0022] A further provision of the above technical solution is that an upper baffle is provided on the first heating area, the upper baffle extending downward from the lower end of the top plate to cover the upper part of the first air outlet surface at the front end of the outer casing.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. The design of radial constraint of the lamp tube by the mounting plate and axial constraint of the clip ensures the installation stability of the lamp tube and the mounting plate; at the same time, both the clip and the mounting plate are simple sheet structures, simplifying the production and assembly process and reducing production costs; furthermore, the design of the limit buckle and limit protrusion prevents the clip from falling off automatically, ensuring the connection stability between the clip and the lamp tube and the mounting plate; the setting of the hand lever facilitates the assembly operation of the clip.

[0027] 2. Set up two heating zones, the first heating zone radiates heat forward and the second heating zone radiates heat upward; after the hot air rises, it dissipates from the top through the second heating zone, ensuring that the heat inside the heater is dissipated in time, improving the heat radiation efficiency and reducing the heat storage of the equipment itself.

[0028] 3. By using an upper baffle to shield the upper part of the first air outlet and a lower baffle to shield the lower part, the small amount of hot air that was originally output from the upper and lower parts changes direction and converges with the hot air in the middle before being output in a concentrated manner, thus improving the uniformity of heat output.

[0042] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0043] like Figure 1-5 As shown in the figure, this embodiment provides a lamp tube snap-fit ​​heater.

[0044] A lamp tube snap-on heater, comprising,

[0045] The outer casing 100 has a first heating area and a second heating area, and the first heating area and the second heating area are connected inside the outer casing 100; the first heating area and the second heating area have different radiation directions.

[0046] The reflector 200 is located inside the first heating zone and is adjacent to the back of the outer casing 100;

[0047] The lamp 300 is located inside the first heating zone;

[0048] The housing 100 is provided with an installation plate 400 that penetrates the first heating zone and the second heating zone, and the lamp tube 300 is inserted through the installation plate 400.

[0049] The mounting plate 400 has a card 500 on its outer side to constrain the lamp tube 300 in the axial direction.

[0050] The above is the basic scheme of this embodiment.

[0051] Specific reference Figure 1 As shown, both the first heating zone and the second heating zone are located inside the outer casing 100. The first heating zone radiates heat towards the front of the outer casing 100, and the second heating zone radiates heat towards the top of the outer casing 100. The top of the first heating zone and the second heating zone are connected.

[0052] The housing 100 is equipped with a switch for controlling the working status of the lamp tube 300.

[0053] Reference Figure 2 As shown, the lamp tube 300 is located in front of the reflector 200. The reflector 200 reflects the heat of the lamp tube 300 and radiates it towards the front of the housing 100. In order to ensure the heat is concentrated, in this embodiment, the reflector 200 includes multiple connected arc-shaped panels. The arc-shaped surfaces reflect the heat that is irradiated onto them and have a junction point on the front end surface of the housing 100 so that the radiation surface is concentrated.

[0054] The structure of the reflector 200 and the radiation direction between the lamp tube 300 are consistent with the reflector 200 on the heater in the prior art, and will not be described in detail here.

[0055] In this embodiment, the mounting plate 400 is provided with a through hole that can accommodate the end of the lamp tube 300. Both ends of the lamp tube 300 pass through the through hole and are installed on the mounting plate 400. The position is limited by the clip 500 on the outside of the mounting plate 400. The mounting plate 400 constrains the radial position of the lamp tube 300, and the clip 500 constrains the axial position of the lamp tube 300, thereby ensuring the stable installation between the lamp tube 300 and the mounting plate 400.

[0056] Furthermore, in this embodiment, the card 500 is set as a separate sheet structure, which is snapped onto the mounting plate 400 after installation. The mounting plate 400 is also a simple sheet structure, which makes the production and assembly process simple, convenient to produce, and low in cost.

[0057] In addition, this embodiment sets up two heating zones. The lamp tube 300 heats the first heating zone. Based on the principle of hot air rising, some of the hot air that cannot be directly radiated from the first heating zone rises to the second heating zone and radiates outward from the top of the outer shell 100. This ensures that the heat inside the heater is dissipated in time, improves the heat radiation efficiency, and reduces the heat storage of the heater itself.

[0058] Specifically, the main body of the card 500 is U-shaped, and the two ends of the lamp tube 300 can be inserted into the recess of the main body;

[0059] The lamp tube 300 is provided with a slot 311 that allows the two clips 510 of the card 500 to be inserted.

[0060] Specific reference Figure 3As shown, in this embodiment, the card 500 has a U-shaped structure. When installing the lamp tube 300, the card 500 is laid down, with the two locking feet 510 arranged vertically. The notch 501 formed between the two locking feet 510 is used to lock the lamp tube 300 in place.

[0061] The upper and lower sides of the portion of the lamp tube 300 extending beyond the mounting plate 400 are provided with slots 311. The card 500 moves horizontally toward the lamp tube 300 from one side, and during the movement, the two locking feet 510 are engaged into the slots 311, limiting the portion of the lamp tube 300 extending beyond the mounting plate 400, preventing the lamp tube 300 from moving toward the other side of the mounting plate 400, thereby constraining the axial displacement of the lamp tube 300.

[0062] In this embodiment, the lamp tube 300 has connecting sections 310 with a diameter larger than that of the lamp tube 300 at both ends, and the slot 311 is provided on the connecting section 310.

[0063] The through holes on the mounting plate 400 are matched with the outer diameter of the connecting joint 310.

[0064] In order to prevent the card 500 from falling off the lamp tube 300, in this embodiment, a limiting buckle 410 is provided on the outer end face of the mounting plate 400, the limiting buckle 410 so that the card 500 is tightly attached to the end face of the mounting plate 400.

[0065] Specific reference Figure 4 As shown, the limiting buckle 410 is formed on the surface of the mounting plate 400 and forms a limiting gap with the mounting plate 400. This limiting gap is just enough to accommodate the card foot 510 of the card 500 to be inserted, thereby limiting the card 500.

[0066] Preferably, in this embodiment, the limiting buckle 410 is a part of the mounting plate 400. A deformable piece is cut on the mounting plate 400 and connected to the mounting plate 400 at only one end. The deformable piece is bent outward to form a limiting gap with the mounting plate 400.

[0067] Preferably, at least two limit buckles 410 are provided and arranged on the upper and lower sides of the lamp tube 300 along the radial direction.

[0068] Preferably, in this embodiment, four limit buckles 410 are provided and arranged symmetrically.

[0069] To prevent the card 500 from automatically detaching from the limiting buckle 410 during use, in this embodiment, the mounting plate 400 is also provided with a limiting protrusion 420. The limiting protrusion 420 is located on the moving path of the card 500 and is used to stop the card 500 from exiting.

[0070] Specific reference Figure 4 As shown, in this embodiment, the limiting protrusion 420 is a protrusion formed on the mounting plate 400 and facing outward. It is set on the moving path of the card 500. When the card 500 moves from one side of the lamp tube 300 to the other side, it undergoes a very small deformation when passing the limiting protrusion 420. After passing the limiting protrusion 420, the card 500 is connected to the lamp tube 300 and the limiting buckle 410. At the same time, the limiting protrusion 420 is located on the sealing side of the U-shaped card 500.

[0071] During use, due to the action of the limiting protrusion 420, the card 500 cannot automatically exit from the installation position. In other words, without the action of external force, the card 500 cannot pass over the limiting protrusion 420 on its own, thus ensuring the connection between the card 500 and the lamp tube 300 and the mounting plate 400.

[0072] In addition, to facilitate the installation of the card 500 onto the lamp tube 300 by the assembly personnel, a hand lever 520 is provided on the card 500 in this embodiment. The hand lever 520 is set perpendicular to the body of the card 500 and the bending direction is away from the mounting plate 400.

[0073] In this embodiment, the mounting plate 400 is connected to the first heater area and the second heating area to simultaneously separate the first heater area and the second heating area from the outer shell 100 and to insulate the outer shell 100. Specifically, the upper end of the mounting plate 400 extends above the first heating area and combines with the top plate 600 of the first heating area to form the second heating area.

[0074] An air outlet slot 601 is provided on the top plate 600.

[0075] In this embodiment, the air outlet 601 is a hollowed-out groove located in the middle of the top plate 600.

[0076] Most of the hot air generated in the first heating zone is output through the first air outlet 101 at the front end of the outer casing 100. A small amount of hot air rises and enters the second heating zone through the air outlet 601, and is then output through the second air outlet 102 at the top of the second heating zone.

[0077] Specific reference Figure 5 As shown in this embodiment, in order to ensure that the second heating area can have a large amount of hot air input, an upper curtain 700 is provided on the first heating area. The upper curtain 700 extends downward from the lower end of the top plate 600 and covers the upper part of the first air outlet surface 101 at the front end of the outer casing 100.

[0078] In this embodiment, due to the arc-shaped structure of the reflector 200, most of the heat is concentrated in the middle of the first air outlet surface 101, while a small amount of heat is output from the upper and lower parts of the first air outlet surface 101, forming an unbalanced state where the temperature is high in the middle and low on the upper and lower sides of the first air outlet surface 101. In order to make the heat output uniform, the upper part of the first air outlet surface 101 is blocked in this embodiment, so that the small amount of hot air in the upper part cannot be output from the first air outlet surface 101, and changes the output direction to move upward or downward. The hot air moving downward converges with the hot air in the middle part and is output from the middle part. The hot air moving upward enters the second heating area through the air outlet 601 and is output from the second air outlet surface 102 on the top of the outer shell 100.

[0079] To further concentrate hot air, in this embodiment, a lower baffle 800 is provided at the lower part of the first heating area. The lower baffle 800 extends upward from the bottom of the first heating area to cover the lower part of the first air outlet 101.

[0080] A small amount of hot air output from the lower part of the first air outlet 101 changes its direction of movement and moves upward due to the setting of the lower baffle 800. After converging with the hot air in the middle of the first heating area, it is output from the middle of the first air outlet 101.

[0081] Preferably, in this embodiment, the outer casing 100 is further provided with a third air outlet surface 103 that communicates with the second heating area, and the third air outlet surface 103 and the first air outlet surface 101 are located on the same plane.

[0082] Preferably, air outlet grilles are provided on the first air outlet surface 101, the second air outlet surface 102, and the third air outlet surface 103.

[0083] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
