Description

Technical Field

[0001] This utility model belongs to the field of water-heated blanket technology, specifically a water-heated blanket main unit. Background Technology

[0002] A water-heated blanket, also known as a water-circulating electric blanket, is a type of electric blanket that uses water circulation for heating. It mainly consists of the blanket body and the main unit. The blanket body contains hot water pipes, and the main unit provides circulating hot water to these pipes to heat the blanket body. During use, the main unit supplies hot water to the blanket body's pipes, heating the blanket body as it flows through them to the desired temperature. After passing through the pipes, the hot water cools and returns to the main unit, where it is reheated and supplied to the blanket body's pipes again.

[0003] However, after prolonged use, the internal parts of the water-heated blanket unit are prone to damage or malfunction. Therefore, it is necessary to disassemble the casing and base to replace and maintain the internal parts. However, the connection between the casing and base is usually made with several screws, requiring tools for proper disassembly and assembly. This makes the assembly and connection method of the water-heated blanket unit relatively complex, causing inconvenience for assembly and maintenance. To address these issues, we provide a water-heated blanket unit solution. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a water-heated blanket main unit.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water-heated blanket main unit, comprising a housing and a base, wherein two opposing side frames are fixedly connected to the inner wall of the housing, and slots are provided on both the left and right sides of the housing, and the slots are connected to the side frames, wherein sliding plates are slidably arranged in both side frames, and the sliding plates extend into the slots, wherein extension slots adapted to the top of the sliding plates are provided on the inner top walls of both slots, and locking mechanisms are provided between the bottom ends of the two sliding plates and the base.

[0006] Preferably, the front and back of the housing are provided with limiting grooves, and two opposing limiting plates are rotatably connected to the base, with the two limiting plates located in the two limiting grooves respectively.

[0007] Preferably, the locking mechanism includes a card seat and a card plate. The card seat is fixedly connected to the base. The right side of the top of the card plate is hinged to the bottom of the side frame. The bottom of the card plate is engaged with the top of the card seat. The bottom of the sliding plate is hinged to a connecting plate. The bottom of the connecting plate is hinged to the left side of the top of the card plate.

[0008] Preferably, a plurality of first springs are fixedly connected to the card holder, and the top end of each first spring is in contact with the bottom surface of the side frame.

[0009] Preferably, both sliding plates have hinged flaps on their sides, and the flaps are located within the slots.

[0010] Preferably, a second spring is fixedly connected to the inner top wall of each of the two side frames, and the bottom ends of the two second springs are respectively fixedly connected to two sliding plates.

[0011] Preferably, suction cups are fixedly connected to the four corners of the bottom surface of the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the coordinated arrangement of side frames, slots, sliding plates, extension slots, a first spring, a second spring, and a locking mechanism, allows the housing to be removed from the base when two flip plates are flipped out. Simultaneously, the thumbs of both hands press on the housing, causing the user to push the two flip plates upwards. This moves the two sliding plates upwards, causing the two connecting plates to pull the two locking plates to swing, thereby releasing the locking plates from the locking seat. Then, the housing is lifted directly upwards, and the base and housing automatically separate under the elastic force of the first spring. When the housing is assembled and fixed to the base downwards, the bottom end of the locking plate slides to one side when it contacts the top end of the locking seat until the bottom end of the locking plate is lower than the top end of the locking seat, at which point it automatically engages and locks with the locking seat, thus ensuring the locking and fixing between the housing and the base.

[0014] 2. With the setting of the limiting plate and the limiting groove, the limiting plate can be rotated and moved into the limiting groove after the shell and the base are assembled, thereby further positioning the shell and the base, preventing misalignment between the shell and the base, and improving the locking stability of the shell and the base.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-8 As shown, this embodiment proposes a water-heated blanket main unit, including a housing 1 and a base 2. Two opposing side frames 11 are fixedly connected to the inner wall of the housing 1. The bottom surface of the side frames 11 is open. Slots 3 are provided on both the left and right sides of the housing 1, and these slots 3 communicate with the side frames 11. Sliding plates 4 are slidably disposed within each of the two side frames 11, extending into the slots 3, allowing the sliding plates 4 to slide up and down within the side frames 11 and the slots 3. The inner top walls of both slots 3 are provided with extension grooves 10 that match the top of the sliding plates 4. When the sliding plates 4 slide upwards, the top of the sliding plates 4 slides into the extension grooves 10, thus ensuring the normal sliding of the sliding plates 4. A locking mechanism is provided between the bottom of the housing 1 and the base 2. With the above structure, the housing 1 and the base 2 can be automatically locked together during fixed assembly without the need for additional parts or auxiliary tools. When it is necessary to separate the housing 1 from the base 2, simply slide the two sliding plates 4 upwards to release the locking effect between the housing 1 and the base 2. The operation is also more convenient, making it easier for personnel to replace and maintain the components between the housing 1 and the base 2. The mechanics, parts and equipment in this device all adopt conventional models in the existing technology, and the circuit connection adopts conventional connection methods in the existing technology, which will not be described in detail here.

[0026] like Figures 1 to 4 and Figure 6 As shown, the front and back of the housing 1 are provided with limiting grooves 6. Two opposing limiting plates 5 are rotatably connected to the base 2, and the two limiting plates 5 are respectively located in the two limiting grooves 6. With the above structure, after the housing 1 and the base 2 are assembled, the limiting plates 5 are rotated and moved into the limiting grooves 6, thereby further positioning the housing 1 and the base 2 and preventing misalignment between the housing 1 and the base 2. In addition, the limiting plates 5 are rotatably mounted on the housing 1 through a damping shaft, so the limiting plates 5 will not swing out randomly in the limiting grooves 6, ensuring the stability of the limiting plates 5 in the limiting grooves 6.

[0027] like Figures 3 to 5 , Figure 7 and Figure 8 As shown, the locking mechanism includes a card holder 8 and a card plate 12. The card holder 8 is fixedly connected to the base 2. The right side of the top of the card plate 12 is hinged to the bottom of the side frame 11. The bottom of the card plate 12 is engaged with the top of the card holder 8. The bottom of the sliding plate 4 is hinged to a connecting plate 13. The bottom of the connecting plate 13 is hinged to the left side of the top of the card plate 12. With the above structure, when the housing 1 is assembled and fixed to the base 2 downwards, the bottom of the card plate 12 will slide to one side when it contacts the top of the card holder 8. When the bottom of the card plate 12 is lower than the top of the card holder 8, it will automatically engage and lock with the card holder 8, thus ensuring the locking and fixing between the housing 1 and the base 2. When the housing 1 and the base 2 need to be separated, simply move the sliding plate 4 in the opposite direction, and the connecting plate 13 will drive the card plate 12 to swing, thereby releasing the bottom of the card plate 12 from the top of the card holder 8. Then the housing 1 can be removed from the base 2.

[0028] like Figure 3 , Figure 5 and Figure 8 As shown, several first springs 9 are fixedly connected to the card holder 8. The top of each first spring 9 is in contact with the bottom surface of the side frame 11. Two positioning blocks are provided in the middle of the first spring 9, and the two positioning blocks are fixedly connected to the bottom surface of the side frame 11 and the upper surface of the card holder 8, respectively. With the setting of the first spring 9, when the card plate 12 is released from the card holder 8, the shell 1 and the base 2 can be automatically separated by the elastic force of the first spring 9. When the shell 1 and the base 2 are assembled, the first spring 9 is in a compressed state.

[0029] like Figure 8 As shown, both sliding plates 4 are hinged to the sides with flaps 15, and the flaps 15 are located in the slots 3. With the flaps 15, it is convenient for personnel to lift the sliding plates 4. When it is necessary to move the sliding plates 4 upward, simply flip the flaps 15 outward so that the flaps 15 are in a horizontal position, and then directly push the flaps 15 upward to move the sliding plates 4 upward, making the operation more convenient.

[0030] like Figure 5 and Figure 8 As shown, the inner top walls of the two side frames 11 are each fixed with a second spring 14. The bottom ends of the two second springs 14 are respectively fixed to the two sliding plates 4. With the setting of the second springs 14, the sliding plates 4 can be automatically reset by the elastic force of the second springs 14, thus ensuring the locking effect between the card plate 12 and the card seat 8.

[0031] like Figure 2 As shown, suction cups 7 are fixed to the four corners of the bottom surface of the base 2. The suction cups 7 ensure the stability of the base 2 after placement and prevent the base 2 from sliding at will.

[0032] The working principle and usage process of this utility model are as follows: When it is necessary to remove the housing 1 from the base 2, firstly, rotate the two limiting plates 5 out of the two limiting grooves 6 respectively, so that the housing 1 can be removed from the base 2 normally. Then, flip the two flip plates 15 out, and at the same time, press the housing 1 with both thumbs, so that the person can push the two flip plates 15 upward, which will drive the two sliding plates 4 to move upward, so that the two connecting plates 13 will pull the two locking plates 12 to swing, thereby making the locking plates 12 and the two sliding plates 12 swing together. After the locking effect of the card holder 8 is released, the housing 1 is lifted directly upward. Under the elastic force of the first spring 9, the base 2 and the housing 1 are automatically separated. When the housing 1 is assembled and fixed with the base 2 downward, the bottom end of the card plate 12 will slide to one side when it contacts the top end of the card holder 8. When the bottom end of the card plate 12 is lower than the top end of the card holder 8, it will automatically engage and lock with the card holder 8, thus ensuring the locking and fixing between the housing 1 and the base 2. Finally, the limiting plate 5 is rotated and swung into the limiting groove 6.
