Description

Technical Field

[0001] This utility model relates to the field of electric heater technology, specifically an electric heater with an easy-to-clean reflector. Background Technology

[0002] Reflective electric heaters, commonly known as "little suns," are very similar in appearance to ordinary household electric fans. They mainly use quartz heating elements and conduct heat through radiation. Similar to ordinary electric fans, reflective electric heaters are also divided into tabletop and floor-standing types. Currently, common reflective electric heaters mainly use a reflector to reflect the heat generated by the heating element for warmth. To prevent users from being burned, a mesh cover is usually installed at the opening of the reflector for protection.

[0003] After a period of use, dust will accumulate on the surface of the reflector of a reflective electric heater, affecting its reflective effect. Therefore, the reflector needs to be cleaned frequently. Currently, most reflective electric heaters use several screws to fix the mesh cover, which is inconvenient for ordinary users to disassemble and assemble, making it difficult to clean the reflector. This needs to be improved. Summary of the Invention

Detailed Implementation

[0019] 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.

[0020] Please see Figures 1-4 In this embodiment of the utility model, an electric heater with an easy-to-clean reflector includes a base 1, a rear cover 2 mounted on the base 1, an insulating seat 4 fixedly mounted inside the rear cover 2, an electric heating tube 5 mounted on the insulating seat 4, a first reflector 6 fixedly mounted at the end of the insulating seat 4 away from the rear cover 2, a second reflector 7 fixedly mounted inside the rear cover 2, an annular groove 8 provided on the inner wall of the opening of the rear cover 2, a connecting ring 11 provided in the annular groove 8, a protective mesh cover 12 fixedly mounted on the outer wall of the connecting ring 11, a plurality of arc-shaped holes 13 and insertion holes 14 provided on the connecting ring 11, one end of the arc-shaped hole 13 communicating with the corresponding insertion hole 14, an insertion rod 9 fixedly mounted on the inner wall of the annular groove 8 at the corresponding position of each arc-shaped hole 13, one end of the insertion rod 9 passing through the arc-shaped hole 13 and fixedly connected to a limiting block 10, the outer diameter of the limiting block 10 being adapted to the diameter of the insertion hole 14.

[0021] By adopting the above-mentioned scheme, after the electric heating tube 5 is activated, the heat emitted by the electric heating tube 5 can be reflected to the outside of the rear cover 2 through the second reflector 7 for the user to warm up. When the second reflector 7 needs to be cleaned, after disconnecting the power supply of the device, simply rotate the connecting ring 11 and the protective mesh cover 12 in the annular groove 8 so that each of the insert rods 9 moves from the arc-shaped hole 13 into the insertion hole 14. Then, pull the protective mesh cover 12 and the connecting ring 11 to the outside of the arc-shaped groove 8 to pull out the limiting block 10 and the insert rods 9 from the insertion hole 14. The protective mesh cover 12 and the connecting ring 11 can then be removed from the rear cover 2. After that, tools can be used to clean the second reflector 7. The operation is simple and convenient.

[0022] After cleaning the second reflector 7, simply align each limiting block 10 and pass it through the corresponding insertion hole 14, then rotate the connecting ring 11 so that the insertion rod 9 re-enters the arc-shaped hole 13, and the protective mesh cover 12 can be installed on the rear cover 2.

[0023] Specific combination Figure 3 In one embodiment of this utility model, the arc-shaped hole 13 and the insertion hole 14 are equidistantly distributed in a circular pattern on the connecting ring 11, thereby facilitating the engagement of the arc-shaped hole 13 and the insertion hole 14 with any insertion rod 9 and the limiting block 10, so as to facilitate the installation of the protective net cover 12 on the rear cover 2.

[0024] Specific combination Figure 3 and Figure 4 In one embodiment of this utility model, the connecting ring 11 has a plurality of positioning holes 15 distributed in a circular pattern at equal intervals. The number of positioning holes 15 is the same as the number of arc-shaped holes 13. A locking mechanism is installed on the outer wall of the rear cover 2, and the locking mechanism is adapted to the positioning holes 15.

[0025] When the positioning hole 15 engages with the locking mechanism, it can restrict the rotation of the connecting ring 11 within the annular groove 8, thereby preventing the connecting ring 11 from falling out of the annular groove 8 without human intervention, thus improving the stability of the protective mesh cover 12 installation.

[0026] Specific combination Figure 4 In one embodiment of this utility model, the locking mechanism includes a locking rod 16 that is movably mounted on the rear cover 2. One end of the locking rod 16 is located in an annular groove 8, and the other end of the locking rod 16 is fixedly connected to a pull ring 20. A sleeve 17 is movably fitted on the outer wall of the locking rod 16 on the outer side of the rear cover 2. The sleeve 17 is fixedly connected to the outer wall of the rear cover 2. A spring 18 is fitted on the outer wall of the locking rod 16 inside the sleeve 17. A baffle 19 is fixedly fitted on the outer wall of the locking rod 16 inside the sleeve 17. The baffle 19 is located between the locking rod 16 and the spring 18.

[0027] By pulling the locking rod 16 through the pull ring 20, the locking rod 16 can be inserted into or disengaged from the corresponding positioning hole 15 to lock or unlock the connecting ring 11 within the annular groove 8. The operation is simple and convenient. Through the setting of the spring 18 and the baffle 19, the locking rod 16 can be prevented from disengaging from the positioning hole 15 without human operation, thereby improving the reliability of the locking mechanism.

[0028] Specific combination Figure 4 Furthermore, based on the previous embodiment, the inner wall of the housing 17 is fixedly installed with a stop 21, and the outer peripheral wall of the baffle 19 is provided with an opening groove 22 that matches the stop 21.

[0029] With the cooperation of the stop 21 and the opening slot 22, when the locking rod 16 is inserted into the positioning hole 15, the baffle 19 is located on one side of the stop 21. At this time, rotating the locking rod 16 will cause the opening slot 22 to be misaligned with the stop 21, thus limiting the locking rod 16 and preventing it from being pulled out of the positioning hole 15, thereby achieving the effect of a child lock. When the locking rod 16 is rotated until the opening slot 22 is aligned with the stop 21, and the locking rod 16 is pulled to disengage it from the positioning hole 15, the baffle 19 will be located on the other side of the stop 21. At this time, rotating the locking rod 16 will cause the opening slot 22 to be misaligned with the stop 21. After releasing the pull ring 20, the stop 21 will limit the baffle 19 to prevent the locking rod 16 from being reinserted into the positioning hole 15 under the action of the spring 18. This makes it easier for the user to operate the protective net cover 12 and the connecting ring 11 with both hands to rotate, making it more convenient to use.

[0030] In addition, in some embodiments of this utility model, the rear cover 2 is rotatably mounted on the base 1, and a handle 3 is fixedly mounted on the outer wall of the rear cover 2.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
