Description

Technical Field

[0001] This utility model belongs to the field of electric heater technology, specifically a highly sealed energy-saving electric heater. Background Technology

[0002] Energy-saving electric heaters are devices in the field of electrothermal technology designed to convert electrical energy into heat energy, achieving higher energy efficiency in the process. The working principle of energy-saving electric heaters is primarily based on the generation of heat through an electric current passing through a resistor, i.e., the process of converting electrical energy into heat energy. When current passes through a resistor, electrons inside the resistor collide with the nuclei of conductor atoms, releasing heat. This heat is then transferred to the medium or object requiring heating through conduction, convection, and radiation. Compared to traditional heating wires, energy-saving electric heaters use non-metallic heating materials, which have higher thermal efficiency and longer service life, and are powered by low-voltage DC electricity, further improving thermal efficiency and reducing energy consumption. However, existing energy-saving electric heaters have a problem where the outlet and pipe connection cannot be tightly sealed, leading to gaps and poor sealing. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a high-sealing energy-saving electric heater, which effectively solves the problem that the outlet of the existing energy-saving electric heater cannot be tightly connected to the pipe, resulting in gaps and poor sealing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing, energy-saving electric heater, comprising an electric heater body, with support legs fixedly installed at both ends of the bottom of the electric heater body, a water outlet pipe fixedly installed at the middle of one end of the bottom of the electric heater body, an installation plate fixedly installed at one end of the electric heater body, a drive motor fixedly installed at the bottom of the installation plate, a transmission component provided at the output end of the drive motor, a sealing gasket fixedly installed inside the water outlet pipe, the sealing gasket being circular, a connector movably inserted into the lower part inside the water outlet pipe, a pipe fixedly installed at the bottom of the connector, four rotating frames fixedly installed at equal intervals in a ring on the lower part of the surface of the water outlet pipe, each of the four rotating frames having a rotatable claw installed at the end away from the water outlet pipe, and a transmission groove opened at the upper end of each of the four claws, the transmission component being connected to the four claws through the four transmission grooves, and when the drive motor is running, the power is output to the four claws through the transmission component, causing the four claws to engage and abut against the connector.

[0005] Preferably, the transmission assembly includes a drive sprocket and a bushing. The drive sprocket is fixedly installed at the output end of the drive motor. A positioning frame is rotatably installed at the bottom of the drive sprocket. The upper part of the positioning frame is fixedly connected to the mounting plate. The bushing is rotatably installed on the upper part of the surface of the water outlet pipe. A mounting ring is fixedly installed in the middle of the surface of the bushing. A driven sprocket is fixedly installed on the upper part of the surface of the bushing. A transmission chain meshes between the driven sprocket and the drive sprocket.

[0006] Preferably, four positioning shaft seats are fixedly installed at equal intervals around the top of the mounting ring, and a transmission bar is rotatably installed on the top of each of the four positioning shaft seats. A rotating shaft seat is fixedly installed on the lower end of each of the four transmission bars.

[0007] Preferably, a transmission block is rotatably mounted on the bottom of each of the rotating shaft seats, and a transmission pin is fixedly mounted on one end of each transmission block. The four transmission pins are respectively movably inserted into the four transmission slots on the four jaws.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: During installation, the operator inserts the connector on the pipe into the inside of the outlet pipe. Then, the operator starts the drive motor to drive the active sprocket to rotate along the positioning frame. When the active sprocket rotates, it drives the driven sprocket to rotate through the transmission chain. When the driven sprocket rotates, it drives the bushing to rotate along the outlet pipe. When the bushing rotates, it pushes the four transmission bars through the mounting ring. When the four transmission bars are pushed, they drive the four transmission pins to move in the transmission grooves of the four claws through the transmission block, thereby driving the four claws to rotate along the four rotating frames, thus clamping the connector and pressing it against the sealing gasket inside the outlet pipe, thereby reducing gaps and ensuring a sealing effect. This allows the outlet pipe of this energy-saving electric heater to be clamped tightly to the pipe, avoiding gaps and improving the sealing effect. Attached Figure Description

A connector 7 is movably inserted into the lower part of the inside of the water outlet pipe 3. A pipe 8 is fixedly installed at the bottom of the connector 7. Four rotating frames 20 are fixedly installed at equal intervals in a ring on the lower part of the surface of the water outlet pipe 3. A claw 19 is rotatably installed at the end of each of the four rotating frames 20 away from the water outlet pipe 3. A transmission groove 21 is opened at the upper end of each of the four claws 19. The transmission component is connected to the four claws 19 through the four transmission grooves 21. When the drive motor 5 is running, it outputs power to the four claws 19 through the transmission component, so that the four claws 19 engage and abut against the connector 7.

[0019] During installation of pipe 8, the operator inserts the connector 7 on pipe 8 into the interior of the outlet pipe 3. Then, the operator starts the drive motor 5 to drive the transmission component. When the transmission component is running, the four transmission slots 21 cooperate to drive the four claws 19 to rotate along the four rotating frames 20, thereby clamping the connector 7 and pressing it against the sealing gasket 6 inside the outlet pipe 3, thus reducing gaps and ensuring a sealing effect. This allows the outlet pipe 3 of this energy-saving electric heater to be clamped tightly together with pipe 8, avoiding gaps and improving the sealing effect.

[0020] The transmission assembly includes a drive sprocket 10 and a bushing 12. The drive sprocket 10 is fixedly installed at the output end of the drive motor 5. A positioning frame 11 is rotatably installed at the bottom of the drive sprocket 10. The upper part of the positioning frame 11 is fixedly connected to the mounting plate 4. The bushing 12 is rotatably installed on the upper part of the surface of the water outlet pipe 3. A mounting ring 15 is fixedly installed in the middle of the surface of the bushing 12. A driven sprocket 13 is fixedly installed on the upper part of the surface of the bushing 12. A transmission chain 14 meshes between the driven sprocket 13 and the drive sprocket 10. Four positioning shaft seats 22 are fixedly installed at equal intervals in a ring on the top of the mounting ring 15. A transmission bar 16 is rotatably installed on the top of each of the four positioning shaft seats 22. A rotating shaft seat 23 is fixedly installed at the lower end of each of the four transmission bars 16. A transmission block 17 is rotatably installed at the bottom of each rotating shaft seat 23. A transmission pin 18 is fixedly installed at one end of each transmission block 17. The four transmission pins 18 are respectively movably inserted into the four transmission slots 21 on the four claws 19.

[0021] The operator starts the drive motor 5, which drives the drive sprocket 10 to rotate along the positioning frame 11. When the drive sprocket 10 rotates, it drives the driven sprocket 13 to rotate through the transmission chain 14. When the driven sprocket 13 rotates, it drives the bushing 12 to rotate along the water outlet pipe 3. When the bushing 12 rotates, it pushes the four transmission bars 16 through the mounting ring 15. When the four transmission bars 16 are pushed, they all drive the four transmission pins 18 to move in the transmission grooves 21 of the four claws 19 through the transmission block 17, thereby driving the four claws 19 to rotate along the four rotating frames 20, and thus clamping the connector 7.
