Description

Technical Field

[0001] This utility model relates to the field of hot air blower technology, and more specifically, to a floor-standing hot air blower. Background Technology

[0002] Floor-standing hot air blowers are a common type of indoor heating equipment that can quickly heat a local space by converting electrical energy into heat energy. Floor-standing hot air blowers typically include a casing, heating elements, and a fan. The casing has an air inlet and an air outlet, and the heating elements include an electric heating mesh, connecting wires, and a controller.

[0003] When a floor-standing hot air blower is working, the fan draws outside air into the casing through the air inlet and blows it out through the air outlet. The electric heating mesh obtains electrical energy through the connecting wires, converts it into heat energy, and transfers it to the air to complete the heating work. However, dust and other particles in the air can easily adhere to the electric heating mesh, affecting its heating effect on the air. Therefore, people need to clean the electric heating mesh regularly.

[0004] Most existing electric heating meshes are fixed to the housing with screws. When cleaning the electric heating mesh, people need to use tools such as brushes to reach into the housing. This method causes the dust to fall into the housing, and the inside of the housing needs to be cleaned later, which is quite inconvenient.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a floor-standing hot air blower.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a floor-standing hot air blower, including a housing and a heating element, wherein an air outlet is provided on the front of the housing, and a dustproof net covering the air outlet is snapped onto the housing; the heating element includes an electric heating mesh and a mounting bracket, the mounting bracket is fixed to the peripheral wall of the air outlet, an elastic block is provided on the peripheral wall of the electric heating mesh, a limiting groove for embedding the elastic block is provided on the inner peripheral wall of the mounting bracket, a square groove is provided on the bottom surface of the electric heating mesh, a contact piece is provided on the bottom wall of the square groove, a connecting seat is provided on the mounting bracket and embedded in the square groove, and an abutment piece is provided on the connecting seat to abut the contact piece.

[0008] The present invention is further configured such that: the side wall of the square groove is connected to the side wall of the electric heating mesh facing away from the dustproof mesh, and two symmetrically arranged inclined grooves are opened on the side wall of the connecting seat facing the dustproof mesh.

[0009] The present invention is further configured such that: the mounting bracket is provided with a shielding plate for contacting the electric heating mesh and closing the square groove, and the projected area of ​​the shielding plate on the dustproof mesh is larger than the opening area of ​​the square groove on the side wall of the electric heating mesh facing away from the dustproof mesh.

[0010] The present invention is further configured such that: the mounting frame is provided with isolation blocks for contacting the left and right side walls of the electric heating mesh.

[0011] The present invention is further configured such that: the elastic block includes a C-shaped deformation sheet and a triangular block fixed on the deformation sheet, wherein the right-angled side of the triangular block is used to abut against the side wall of the limiting groove near the dustproof net.

[0012] The present invention is further configured such that: the deformable sheet and the triangular block are integrally formed, and the elastic block is made of polyphenylene sulfide material.

[0013] In summary, this utility model has the following beneficial effects: Apply force to the dustproof mesh to disengage the clip from the interface. Then, press the elastic block to deform it and disengage it from the limiting groove. This allows the elastic block to no longer restrain the heating mesh on the mounting frame, enabling the entire heating mesh to be removed. This design makes disassembly of the heating mesh much faster than in existing technologies. By moving the heating mesh to a convenient cleaning location such as a bathroom, and using tools such as a brush to clean it, the dust removed from the heating mesh will not fall into the housing, reducing the frequency of internal cleaning. After cleaning the heating mesh, reinstall it onto the mounting frame, allowing the elastic block to re-embed in the limiting groove, thus better restraining the heating mesh on the mounting frame. At this point, the connector engages in the square groove, causing the contact piece to contact with the contact plate, thereby forming a circuit between the heating mesh and the external circuit, ensuring that the heating mesh can work normally when the floor-standing hot air blower is powered on.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Floor-standing hot air blowers, such as Figures 1 to 3 As shown, the device includes a housing 1 and a heating element. The housing 1 has an air outlet 2 on its front side. A dustproof mesh 3 covering the air outlet 2 is snapped onto the housing 1, and a buckle 16 is fixed to the dustproof mesh 3. The housing 1 also has a slot 17 on its front side for the buckle 16 to pass through. The heating element includes a heating mesh 4 and a mounting bracket 5. The outer peripheral wall of the mounting bracket 5 is fixed to the peripheral wall of the air outlet 2. An elastic block is provided on the peripheral wall of the heating mesh 4, and a recess for the elastic block to be embedded is provided on the inner peripheral wall of the mounting bracket 5. The limiting groove 6, the bottom surface of the electric heating mesh 4 is provided with a square groove 7, the bottom wall of the square groove 7 is provided with a contact piece 8, the mounting bracket 5 is provided with a connecting seat 9 embedded in the square groove 7, the connecting seat 9 is provided with a contact piece 10 that abuts against the contact piece 8, and the connecting seat 9 is provided with a connecting wire connected to the contact piece 10. When it is necessary to clean the electric heating mesh 4, the power of the floor-standing hot air blower is turned off, force is applied to the dustproof mesh 3, so that the buckle 16 is disengaged from the buckle interface 17, and then the elastic block is pressed to make The elastic block deforms and disengages from the limiting groove 6, allowing the heating mesh 4 to be removed from the mounting frame 5. This design makes the removal of the heating mesh 4 much faster than in existing technologies. The heating mesh 4 can be moved to a convenient place such as the bathroom and cleaned with a brush or other tools. This design prevents the dust removed from the heating mesh 4 from falling into the housing 1, reducing the frequency of cleaning the inside of the housing 1. After cleaning the heating mesh 4, it is reinstalled onto the mounting frame 5, allowing the elastic block to re-embed in the limiting groove 6. This allows the elastic block to better restrain the heating mesh 4 on the mounting frame 5. At this time, the connecting seat 9 is inserted into the square groove 7, causing the contact piece 10 to contact the contact piece 8, thus forming a circuit between the heating mesh 4 and the external circuit, ensuring that the heating mesh 4 can work normally when the floor-standing hot air blower is powered on.

[0018] like Figures 1 to 4As shown, the sidewall of the square groove 7 is connected to the sidewall of the electric heating mesh 4 facing away from the dustproof mesh 3. This arrangement allows the bottom surface of the electric heating mesh 4 to be placed on the inner wall of the mounting bracket 5 during installation. By pushing the electric heating mesh 4, the connecting seat 9 passes through the sidewall of the electric heating mesh 4 facing away from the dustproof mesh 3 and is embedded in the square groove 7. The connecting seat 9 has two symmetrically arranged inclined grooves 11 on the sidewall facing the dustproof mesh 3. Specifically, the two edges of the connecting seat 9 facing the sidewall facing the dustproof mesh 3 are chamfered. This arrangement makes the area of ​​the connecting seat 9 facing the sidewall facing the dustproof mesh 3 smaller than the opening area of ​​the square groove 7 on the sidewall of the electric heating mesh 4 facing away from the dustproof mesh 3, which facilitates the embedding of the connecting seat 9 in the square groove 7 and reduces the need for manual intervention. The time spent aligning the square groove 7 and the connecting seat 9 is reduced. The mounting bracket 5 is fixed with a shielding plate 12 to abut against the heating mesh 4 and close the square groove 7. The projected area of ​​the shielding plate 12 on the dustproof mesh 3 is larger than the opening area of ​​the square groove 7 on the side wall of the heating mesh 4 facing away from the dustproof mesh 3. When the elastic block is embedded in the limiting groove 6 and restricts the heating mesh 4 to the mounting bracket 5, the shielding plate 12 can close the square groove 7, reducing the possibility of dust entering the square groove 7 during use of the floor-standing hot air blower. The mounting bracket 5 is equipped with isolation blocks 13 for abutting against the left and right side walls of the heating mesh 4. The distance between the left and right isolation blocks 13 is equal to the width of the heating mesh 4. This arrangement reduces the contact time between the heating mesh 4 and the mounting bracket. The contact area between the 5 is reduced, minimizing the amount of heat conducted to the mounting frame 5 when the electric heating mesh 4 is working. The isolation block 13 and the connecting seat 9 are integrally formed on the mounting frame 5. The isolation block 13, the connecting seat 9, and the mounting frame 5 are all made of PA66 material and processed by injection molding. The elastic block includes a C-shaped deformation piece 14 and a triangular block 15 fixed on the deformation piece 14. The right-angled side of the triangular block 15 is used to abut against the side wall of the limiting groove 6 near the dustproof mesh 3. This design ensures that when the triangular block 15 is embedded in the limiting groove 6, the right-angled side of the triangular block 15 can fit against the side wall of the limiting groove 6 near the dustproof mesh 3, ensuring the stability of the triangular block 15 in the limiting groove 6 and preventing the triangular block 15 from easily falling out of the limiting groove 6. The electric heating mesh 4 is disengaged to ensure its stability on the mounting frame 5. During the installation of the electric heating mesh 4 onto the mounting frame 5, the hypotenuse of the triangular block 15 can abut against the inner peripheral wall of the mounting frame 5. The force exerted by the mounting frame 5 on the triangular block 15 forms a component force along the hypotenuse that causes the initial deformation piece 14 to deform, facilitating the embedding of the triangular block 15 into the limiting groove 6. The deformation piece 14 and the triangular block 15 are integrally formed, which ensures the integrity of the deformation piece 14 and the triangular block 15. The elastic block is made of polyphenylene sulfide material through injection molding. Polyphenylene sulfide has good deformation recovery ability, which allows the deformation piece 14 to recover its original shape in time after deformation. The deformation piece 14 is fixedly installed on the electric heating mesh 4 by rivets.
