Description

Technical Field

[0001] This utility model relates to the field of heater technology, and more specifically, it relates to a heater protective cover. Background Technology

[0002] A warm air heater mainly consists of a motor, heating element, fan impeller, air guide cover, dust cover, air inlet and air outlet. Its principle is that the motor drives the fan impeller to rotate, drawing air in from the air inlet. After being heated by the heating element, the air becomes hot air and is blown into the room from the air outlet. The indoor heating is achieved by utilizing the flow of hot air and the temperature difference effect.

[0003] The dust cover on the heater needs to be disassembled and cleaned regularly to improve the heating effect. Currently, most dust covers are installed using clips and slots. This method requires the worker to hold the dust cover and align the clips with the slots. After alignment, the worker must press firmly to complete the installation. If the clips shift during this pressing process, they are easily damaged or broken, reducing the dust cover's lifespan and making installation and removal inconvenient. Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heater protective cover.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a protective cover for a heater, comprising a left shell and a right shell, wherein the left shell and the right shell are detachably connected, and a fan impeller and an electric heating element are detachably connected to the left shell and the right shell respectively, and a protective cover is detachably connected to the side of the right shell away from the left shell.

[0006] By adopting the above technical solution, after the heater is installed as a whole through the left and right shells, the start-up of the fan impeller and heating element can be controlled by the knobs on the left and right shells, so that the heater can be used normally.

[0007] The present invention is further configured such that: the protective cover is U-shaped; a hinge and a limiting plate are fixedly connected to the end of the protective cover near the right shell; an insertion port is provided on the edge of the right shell away from the protective cover; the hinge and the limiting plate are respectively disposed in the insertion port; a buckle is fixedly connected to the upper side of the protective cover near the right shell; the buckle is made of copper alloy; multiple sets of holes are opened on the protective cover; and two sets of hinges and limiting plates are respectively provided along the edge of the protective cover.

[0008] By adopting the above technical solution, the hinge on the protective cover is first inserted into the center, and then the protective cover is swung around the axis on the hinge to insert the limiting plate on the other side, thereby facilitating the disassembly or installation of the protective cover.

[0009] The present invention is further configured as follows: a snap-fit ​​groove is fixedly connected to the side of the right shell away from the protective cover; a sliding column is slidably connected to the right shell; a pressing plate is fixedly connected to the end of the sliding column; a push plate is fixedly connected to the end of the sliding column away from the pressing plate; the push plate is slidably connected to the top of the snap-fit ​​groove; a spring is fixedly connected to the side of the push plate near the sliding column; the end of the spring away from the push plate is fixedly connected to the inner side of the right shell; the sliding column is disposed on the inner ring surface of the spring; the snap-fit ​​groove is internally through-connected; two sets of snap-fit ​​grooves are arranged along the center of the right shell; the buckles are J-shaped; two sets of buckles are respectively arranged along the surface of the right shell; and the two sets of buckles are snap-fit ​​connected to the two sets of snap-fit ​​grooves respectively.

[0010] By adopting the above technical solution, pressing the protective cover causes the buckle to enter the locking groove. Then, the curved part of the buckle will engage with the top of the locking groove, so that the buckle and the locking groove are engaged with each other, thus fixing the right shell and the protective cover. When removing the protective cover, pressing the pressing plate will move the sliding column and the push plate. During the movement of the push plate, it will contact the buckle in the locking groove, causing the buckle to disengage from the locking groove. At this time, the protective cover can be pulled by the staff to disengage the upper plate of the protective cover and cause the protective cover to swing around the axis on the hinge. Then, the staff can pull out the hinge, thereby removing the protective cover for cleaning and other operations.

[0011] In summary, this utility model has the following beneficial effects: the protective cover can be installed by rotating the hinge, and then the buckle can be pressed to engage with the snap-fit ​​groove. This design makes the protective cover easy to install and remove without losing the effect of stable installation. Furthermore, the setting of the pressing plate, sliding column and push plate allows the protective cover to be separated from the right shell by the snap-fit ​​method by the operator with a gentle press, thereby reducing the cumbersome process of the operator when disassembling or installing the protective cover and improving the convenience of installation or disassembly.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Please refer to the implementation details of this utility model. Figures 1 to 6 A protective cover for a heater includes a left housing 1 and a right housing 2, which are detachably connected. A fan impeller 4 and an electric heating element 5 are detachably connected to each other in the left housing 1 and right housing 2, respectively. A protective cover 3 is detachably connected to the side of the right housing 2 away from the left housing 1. In this embodiment, the left housing 1 and right housing 2 are connected by bolts. A switch knob is provided on the top of the left housing 1 and right housing 2 to control the switching of the fan impeller 4 and the electric heating element 5. The power supply for the fan impeller 4 and the electric heating element 5 is provided by an external power cord.

[0021] The following details the specific structure of the detachable connection between the protective cover 3 and the right shell 2. Please refer to the following: Figure 4 and Figure 6 The protective cover 3 is U-shaped. A hinge 11 and a limiting plate 13 are fixedly connected to the end of the protective cover 3 near the right shell 2. An insertion port 14 is provided on the edge of the right shell 2 away from the protective cover 3. The hinge 11 and the limiting plate 13 are respectively placed in the insertion port 14. A buckle 12 is fixedly connected to the upper side of the protective cover 3 near the right shell 2. The buckle 12 is made of copper alloy. In this embodiment, the hinge 11 is divided into a shaft and a blade. The buckle 12 is made of copper alloy because copper alloy has a certain hardness, strength and flexibility. Therefore, when the buckle 12 is inserted into the snap-fit ​​groove 6, the protrusion on the buckle 12 will squeeze the buckle 12 and make the buckle 12 bend. When the protrusion of the buckle 12 passes through the snap-fit ​​groove 6, the buckle 12 loses its bending force and snaps the protrusion of the buckle 12 with the top of the snap-fit ​​groove 6, thereby achieving the snap-fit ​​effect and improving the connection effect between the right shell 2 and the protective cover 3.

[0022] The following details the disassembly of the right shell 2 and protective cover 3. Please refer to the following: Figure 4 and Figure 5 A snap-fit ​​groove 6 is fixedly connected to the side of the right housing 2 away from the protective cover 3. A sliding column 8 is slidably connected in the right housing 2. A pressing plate 10 is fixedly connected to the end of the sliding column 8. A push plate 7 is fixedly connected to the end of the sliding column 8 away from the pressing plate 10. The push plate 7 is slidably connected to the top of the snap-fit ​​groove 6. Multiple sets of holes are opened on the protective cover 3. Two sets of hinges 11 and limiting plates 13 are respectively provided along the edge of the protective cover 3. A spring 9 is fixedly connected to the side of the push plate 7 near the sliding column 8. The end of the spring 9 away from the push plate 7 is fixedly connected to the top of the snap-fit ​​groove 6. Inside the right housing 2, the sliding post 8 is set on the inner ring surface of the spring 9. The snap-fit ​​groove 6 is internally through-hole set. Two sets of snap-fit ​​grooves 6 are set along the center of the right housing 2. The buckle 12 is J-shaped and two sets of buckles 12 are set along the surface of the right housing 2. The two sets of buckles 12 are snap-fit ​​connected to the two sets of snap-fit ​​grooves 6 respectively. In this embodiment, the outer ring surface of the sliding post 8 is set with the spring 9. The sliding post 8 can not only drive the push plate 7 to move, but also act as a damping rod of the spring 9, improving the stability of the spring 9 when compressed or stretched.

[0023] Working principle: First, the operator connects the left shell 1 and the right shell 2 with bolts. Then, the operator holds the protective cover 3 and inserts the two hinges 11 fixed on the protective cover 3 into the slots 14 respectively. Then, the operator manually swings the protective cover 3 so that the protective cover 3 swings along the axis of the hinge 11, so that the two limiting plates 13 fixed on the other side of the protective cover 3 are inserted into the slots 14 on the other side. This allows the protective cover 3 to be installed on the side of the right shell 2 away from the left shell 1. This design facilitates the installation of the protective cover 3 and the alignment between the buckle 12 and the snap-fit ​​groove 6, without the operator having to constantly align the protective cover 3 by hand.

[0024] When it is necessary to fix the protective cover 3, the hinge 11 and the limiting plate 13 on the protective cover 3 are inserted into the socket 14, and the buckle 12 on the protective cover 3 is in the locking groove 6. However, the buckle 12 is not fully inserted into the locking groove 6. Therefore, it is necessary for the staff to press the protective cover 3 to make the buckle 12 enter the locking groove 6. Then, the bent part of the buckle 12 (please refer to the details) Figure 6 The buckle 12 will be snapped into the top of the snap-fit ​​groove 6, so that the buckle 12 and the snap-fit ​​groove 6 are snapped into each other, thus completing the effect of fixing the right shell 2 and the protective cover 3. Then, the device is moved to the designated location. Then, the staff turns the knobs on the top of the left shell 1 and the right shell 2 to start the fan impeller 4 and the electric heating element 5 between the left shell 1 and the right shell 2 respectively. This allows the heat generated by the electric heating element 5 to be blown from the fan impeller 4 to the outside of the left shell 1 and the right shell 2, realizing the normal working principle of the heater.

[0025] When the dust on the protective cover 3 needs to be removed and cleaned, the staff needs to press the pressing plate 10 to move the sliding column 8 and the push plate 7. During the movement of the push plate 7, it will contact the buckle 12 in the locking position, so that the buckle 12 will disengage from the locking groove 6. At this time, the staff can then pull the protective cover 3 to make the upper limit plate 13 of the protective cover 3 disengage from the insertion port 14 and make the protective cover 3 swing around the axis on the hinge 11. Then the staff can pull out the hinge 11 to remove the protective cover 3 for cleaning and other operations.
