Description

Technical Field

[0001] The present invention belongs to the technical field of electric heating, and more specifically, particularly relates to a heater. Background Art

[0002] A heater is a device that uses electrical energy to generate heat. It is mainly composed of a heating element, a casing and a temperature control device. The heating element is generally a resistance wire. When current passes through, according to Joule's law, electrical energy will be converted into thermal energy, thereby generating heat. The casing protects the internal components and acts as a heat insulator, which can prevent users from accidentally contacting high-temperature components and reduce heat loss. The temperature control device can control the temperature of the heater. When the temperature reaches the set value, it can automatically adjust the heating power to keep the temperature within an appropriate range. There are various types of heaters, including low-power desktop heaters for local heating, and high-power industrial heaters that can be used for industrial processes such as drying and preheating.

[0003] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0004] When the heater is working, the flow of surrounding air will cause dust to be adsorbed onto the surface of the heating element along with the airflow. If there is too much dust on the surface of the heating element, it may hinder heat dissipation and cause the element to be in a high temperature state for a long time, causing the heater to age and damage the element, thus reducing the service life of the heating element.

[0005] In view of this, the existing structure and defects are studied and improved, and a heater is provided. Summary of the invention

[0010] Preferably, the side surface of the translational push plate is fixedly connected to a limit block, which passes through a connecting mechanism and is engaged with the protective plate. When the limit block is engaged with the limit slot at the upper end, the connection interface is in a closed state, and the lower end of the protective plate will rest against the support seat.

[0011] Preferably, a movable groove is provided at the upper end of the connecting mechanism, and a paddle is provided inside the movable groove. The lower end of the paddle passes through the movable groove and is fixedly connected to the translation push plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, a cleaning rubber brush is provided. When dust adheres to the surface of the heating unit, the staff presses the annular plate two, and the annular plate two drives the connecting column to move. At this time, the two connecting columns drive the movable annular plate one and the cleaning rubber brush to move along the surface of the heating unit. The cleaning rubber brush can effectively clean the dust on the surface of the heating unit, avoid dust accumulation affecting the heating efficiency and equipment life, ensure stable operation of the equipment, reduce the risk of failure caused by dust, improve the overall reliability and durability of the equipment, and reduce maintenance costs and downtime.

[0018] In the present invention, two limiting strips are provided. When the staff moves the annular plate 2, since the annular plate 2 is clamped with the two limiting strips, the annular plate 2 will move along the connecting column. The clamping structure makes the movement of the annular plate 2 more guided and stable, accurately controls the actions of related components, prevents offset and dislocation, improves the coordination of the internal operation of the device, ensures that the cleaning operation is carried out accurately and effectively, thereby improving the accuracy and stability of the equipment operation and extending the equipment service life.

[0019] In the present invention, by providing a second spring, when the staff moves the second ring plate, the second spring is squeezed, and the cleaning rubber brush cleans the heating unit. When the staff releases the second ring plate, the second spring is no longer squeezed, and the second spring pushes the second ring plate to reset, so that the second ring plate drives the cleaning rubber brush back to its original position. When the second spring is reset, the limiting circular plate will press against the connecting rod on the second ring plate, so that the second ring plate will not move excessively and cause the second ring plate to separate from the device body. Such a design greatly improves the self-recovery ability of the equipment, ensures that each cleaning process is smooth, reduces manual intervention, and reduces the risk of equipment damage.

[0020] In the present invention, a limit card block is provided, and when the connection interface is not in use, the staff can toggle the paddle, and the paddle drives the translation push plate and the limit card block to move, thereby moving the lower end of the protective plate to the top of the support seat. At this time, the paddle is manipulated to move the limit card block to a position corresponding to the upper limit card slot. At this time, the limit card block is connected to the protective plate through the upper limit card slot, and the protective plate will isolate the joint of the connection interface from the external environment, thereby preventing impurities such as dust and water vapor from invading the interior of the connection interface and causing problems such as poor contact or short circuit.

[0021] In the present invention, a spring is provided. When the staff pushes the paddle to move the translation push plate and the limit block, the spring is squeezed. When the staff releases the paddle, the spring pushes the translation push plate to return to its original position. Since the translation push plate and the limit block are pushed by the spring, the spring can make the connection between the limit block and the protective plate more stable and will not be easily displaced, thereby improving the reliability of the protective plate. Even if the equipment is vibrated or slightly collided, the protection is still firm, effectively preventing foreign objects from invading the connection interface, ensuring stable operation of the equipment, and reducing potential faults.

When the staff moves the annular plate 24, since the annular plate 24 is engaged with the two limiting strips 29, the annular plate 24 will move along the connecting column 28.

The lower end of the paddle 22 passes through the moving groove 23 and is fixedly connected to the translation push plate 26. When the paddle 22 is toggled, the paddle 22 will drive the translation push plate 26 and the limit block 21 to move. At this time, the spring 1 24 is deformed. When the paddle 22 is released, the spring 1 24 is reset to push the translation push plate 26 and the limit block 21 to engage with the protective plate 15.

When the staff moves the annular plate 2 34, the spring 2 33 is squeezed, and the cleaning rubber brush 30 cleans the heating unit 13. When the staff releases the annular plate 2 34, the spring 2 33 is no longer squeezed, and the spring 2 33 pushes the annular plate 2 34 to reset, so that the annular plate 2 34 drives the cleaning rubber brush 30 back to the original position, and when the spring 2 33 is reset, the limiting circular plate 35 will resist the connecting rod 36 on the annular plate 2 34, so that the annular plate 2 34 will not move excessively and cause the annular plate 2 34 to be separated from the device body 11. Such a design greatly improves the self-recovery ability of the equipment, ensures that each cleaning process is smooth, reduces manual intervention, and reduces the risk of equipment damage.

[0035] An annular plate 2 34 is provided at one end of the limiting plate 31, and two connecting columns 28 are fixedly connected to the side surface of the movable annular plate 1 27, and the two connecting columns 28 are both fixedly connected to the annular plate 2 34 through the limiting plate 31. When the annular plate 2 34 moves, the annular plate 2 34 will drive the movable annular plate 1 27 to move through the connecting columns 28, and the movable annular plate 1 27 drives the cleaning rubber brush 30 to clean along the surface of the heating unit 13. Two limiting strips 29 are provided inside the device body 11, and the two limiting strips 29 are parallel to each other. The two limiting strips 29 are both connected to the inner wall of the device body 11.

At this time, the paddle 22 is manipulated to move the limit block 21 to the position corresponding to the upper limit slot 16. At this time, the limit block 21 is connected with the protective plate 15 through the upper limit slot 16, and the protective plate 15 will isolate the connector of the connection interface 14 from the external environment, thereby preventing impurities such as dust and water vapor from invading the interior of the connection interface 14 and causing problems such as poor contact or short circuit.

[0036] Both ends of the annular plate 34 are provided with limiting grooves 37, and the two limiting strips 29 are clamped with the two ends of the annular plate 34 through the limiting grooves 37. The annular plate 34 is clamped with the two limiting strips 29, so the annular plate 34 can only move linearly along the limiting strips 29. A connecting rod 36 is provided inside the annular plate 34, and both ends of the connecting rod 36 are fixedly connected to the inner wall of the annular plate 34. A fixed long rod 32 is sleeved on the midpoint of the connecting rod 36, and one end of the fixed long rod 32 is fixedly connected to the heating unit 13.

When the staff member turns the paddle 22 to move the translation push plate 26 and the limit block 21, the spring 1 24 is squeezed. When the staff member releases the paddle 22, the spring 1 24 pushes the translation push plate 26 to reset. Since the translation push plate 26 and the limit block 21 are pushed by the spring 1 24, the spring 1 24 can make the connection between the limit block 21 and the protective plate 15 more stable and will not be easily displaced, thereby improving the reliability of the protective plate 15. Even if the equipment is vibrated or slightly collided, the protection is still firm, effectively preventing foreign objects from invading the connection interface 14, ensuring stable operation of the equipment, and reducing potential faults.

[0064] Working principle:

[0065] In the first step, when dust adheres to the surface of the heating unit 13, the staff presses the annular plate 2 34, and the annular plate 2 34 drives the connecting column 28 to move. At this time, the two connecting columns 28 drive the movable annular plate 1 27 and the cleaning rubber brush 30 to move along the surface of the heating unit 13. The cleaning rubber brush 30 can effectively clean the dust on the surface of the heating unit 13, avoid dust accumulation affecting the heating efficiency and equipment life, ensure stable operation of the equipment, reduce the risk of failure caused by dust, improve the overall reliability and durability of the equipment, and reduce maintenance costs and downtime.

[0066] In the second step, when the staff moves the annular plate 2 34, since the annular plate 2 34 is clamped with the two limit strips 29, the annular plate 2 34 will move along the connecting column 28. The clamping structure makes the movement of the annular plate 2 34 more guided and stable, accurately controls the actions of related components, prevents displacement and misalignment, improves the coordination of the internal operation of the device, ensures that the cleaning operation is carried out accurately and effectively, thereby improving the accuracy and stability of the equipment operation and extending the equipment service life.

[0067] In the third step, when the staff moves the annular plate 2 34, the spring 2 33 is squeezed, and the cleaning rubber brush 30 cleans the heating unit 13. When the staff releases the annular plate 2 34, the spring 2 33 is no longer squeezed, and the spring 2 33 pushes the annular plate 2 34 to reset, so that the annular plate 2 34 drives the cleaning rubber brush 30 back to the original position, and when the spring 2 33 is reset, the limiting circular plate 35 will resist the connecting rod 36 on the annular plate 2 34, so that the annular plate 2 34 will not move excessively and cause the annular plate 2 34 to separate from the device body 11. Such a design greatly improves the self-recovery ability of the equipment, ensures that each cleaning process is smooth, reduces manual intervention, and reduces the risk of equipment damage.

[0068] In the fourth step, when the connection interface 14 is not in use, the staff member moves the paddle 22, and the paddle 22 drives the translation push plate 26 and the limit block 21 to move, and moves the lower end of the protective plate 15 to the top of the support seat 19. At this time, the paddle 22 is manipulated to move the limit block 21 to the position corresponding to the upper limit slot 16. At this time, the limit block 21 is connected with the protective plate 15 through the upper limit slot 16, and the protective plate 15 will isolate the connector of the connection interface 14 from the external environment, thereby preventing impurities such as dust and water vapor from invading the interior of the connection interface 14 and causing problems such as poor contact or short circuit.

[0069] In the fifth step, when the staff member turns the paddle 22 to move the translation push plate 26 and the limit block 21, the spring 1 24 is squeezed at this time. When the staff member releases the paddle 22, the spring 1 24 pushes the translation push plate 26 to return to its original position. Since the translation push plate 26 and the limit block 21 are pushed by the spring 1 24, the spring 1 24 can make the connection between the limit block 21 and the protective plate 15 more stable and will not be easily displaced, thereby improving the reliability of the protective plate 15. Even if the equipment is vibrated or slightly collided, the protection is still firm, effectively preventing foreign objects from invading the connection interface 14, ensuring the stable operation of the equipment, and reducing potential faults.

[0070] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
