Description

Technical Field

[0001] This utility model relates to the field of air deflector technology, and in particular to air deflector for ventilation openings. Background Technology

[0002] In daily life, to prevent airflow from blowing directly at people, people often place air vent deflectors on vents, installing them either outside or inside the vent. Their main function is to guide and change the direction of airflow, improving the efficiency and safety of the ventilation system. In existing technology, air vent deflectors are magnetically attached to the vent. However, due to the weak adhesion of existing magnets, they are prone to falling off or being accidentally knocked off. If they fall, the magnet may detach from the air vent deflector, easily causing damage or breakage, affecting its normal use and rendering it unusable for the user. Utility Model Content

[0003] The technical problem to be solved by this utility model is: In order to solve the problem that the existing ventilation vent guide cover is installed at the ventilation vent by magnetic attraction, and due to the poor attraction force of the existing magnet, it is easy to fall off or be accidentally knocked off. After falling off, the magnet will fall outside the ventilation vent guide cover, which can easily cause the ventilation vent guide cover to be broken or the magnet to be broken, affecting the normal use of the ventilation vent guide cover and causing the user to be unable to use it normally. The ventilation vent guide cover is now provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a vent guide cover, including a guide cover body, a guide groove for changing the air direction of the vent is provided on one side of the guide cover body, a placement groove is provided at one end of the guide cover body located in the guide groove, a magnetic suction component is provided in the placement groove, and a limiting mechanism for limiting the displacement range of the magnetic suction component is provided in the placement groove.

[0005] The limiting mechanism includes a limiting pin, which is positioned on the inner peripheral walls of both sides of the placement slot along the magnetic attraction assembly on one side of the air guide body towards the magnetic attraction assembly on the other side. The magnetic attraction assembly has a limiting groove, and the limiting pin is positioned within the limiting groove. Compared to existing technologies that rely solely on the cooperation of positioning grooves and positioning blocks, this solution, by setting a limiting mechanism within the placement slot, uses the limiting pin of the limiting mechanism and the limiting groove on the magnetic attraction assembly to ensure that the magnetic attraction assembly can only move within the placement slot. This confines the magnetic attraction assembly within the placement slot, preventing it from being thrown out and broken if the air guide body falls, thus ensuring the stable and reliable use of both the magnetic attraction assembly and the air guide body.

[0006] To better constrain the magnetic suction assembly, in some preferred embodiments, there are two limiting pins located on both sides of the magnetic suction assembly. The limiting pins and limiting grooves on both sides of the magnetic suction assembly cooperate to better constrain the magnetic suction assembly placed within the grooves, ensuring stable and reliable upper limit positioning of the magnetic suction assembly's guide cover body.

[0007] To ensure the magnetic component has sufficient floating space within the placement slot and to guarantee its adsorption at the vent, in some preferred embodiments, the diameter of the limiting groove is larger than the diameter of the limiting pin. By making the diameter of the limiting groove larger than the diameter of the limiting pin, the magnetic component has sufficient displacement space within the placement slot, allowing it to float and protrude from the mounting surface on one side of the guide vane body. This ensures stable and reliable contact and adsorption between the magnetic component and the vent.

[0008] To facilitate the installation of the locating pin on the placement groove, in some preferred embodiments, the placement groove has a pin hole that matches the locating pin, and the locating groove is disposed within the pin hole. The locating pin and the pin hole cooperate to install the locating pin on the placement groove.

[0009] To facilitate the engagement of the limiting pin and the pin hole, in some preferred embodiments, the pin hole is frustoconical, with the larger end of the pin hole located at the end of the placement groove furthest from the guide groove, and the smaller end located at the end of the placement groove closest to the guide groove. The limiting pin and the pin hole are press-fitted. By setting the pin hole to a frustoconical shape, the limiting pin can be quickly placed into the pin hole, and the press-fitted pin and pin hole fix each other, thus achieving the installation of the limiting pin on the guide cover body.

[0010] To facilitate the installation of the magnetic assemblies, in some preferred embodiments, a positioning block is provided on the inner peripheral wall of the placement groove, and a positioning groove is provided on the magnetic assemblies. The positioning block is disposed within the positioning groove, and positioning blocks are disposed opposite each other on the inner peripheral walls of the placement groove. The diameter of the positioning block is smaller than the diameter of the positioning groove. By providing positioning blocks on the inner peripheral wall of the placement groove and positioning grooves on the magnetic assemblies, the positioning blocks and positioning grooves cooperate to quickly position the magnetic assemblies, improving installation efficiency.

[0011] Since the material of the vent may be iron, aluminum, or wood, to accommodate vents made of different materials, in some preferred embodiments, the air deflector body has outwardly extending side wings on one side of the placement slot, and mounting holes are provided on the side wings. By providing mounting holes on the side wings, the air deflector body can be fixed to the vent through the mounting holes, which facilitates the installation of the air deflector body and improves the adaptability of the air deflector body.

[0012] To accommodate different types of vents, some preferred embodiments include a mounting hole comprising an oblong section and a circular section connected to one end of the oblong section. The diameter of the circular section is larger than the diameter of the oblong section. After the screw is fixed in a preset position at the vent by the engagement of the circular section and the oblong section, the screw is then passed through the circular section into the oblong section, and finally tightened to secure the vent body. This facilitates the fixation of the vent body.

[0013] To accommodate different types of vents, in some preferred embodiments, the air deflector body includes two slidably disposed first and second air deflectors. The first and second air deflectors slide relative to each other, and the length of the air deflector groove between them can be adjusted to meet the needs of different types of vents, thus improving the applicability of the air deflector body.

[0014] To enable relative sliding of the first and second wind shields, in some preferred embodiments, a plurality of first protrusions are provided at the upper end of the outer peripheral surface of the first wind shield, the plurality of first protrusions are spaced apart along the sliding direction, and a first groove is formed between the plurality of first protrusions and the outer peripheral wall of the first wind shield. A plurality of second protrusions are provided at the lower end of the outer peripheral surface of the first wind shield, the plurality of second protrusions are spaced apart along the sliding direction, and a second groove is formed between the plurality of second protrusions and the outer peripheral wall of the first wind shield. The first groove and the second groove are arranged opposite to each other and form a sliding groove that matches the second wind shield. The second wind shield is slidably disposed in the sliding groove.

[0015] The beneficial effects of this utility model are as follows: When the ventilation vent guide cover of this utility model is in use, a limiting mechanism is set in the placement groove, and the limiting pin of the limiting mechanism cooperates with the limiting groove on the magnetic suction component to restrict the magnetic suction component in the placement groove. In the event of a fall, the magnetic suction component will not be dropped and broken, ensuring the stable and reliable use of the magnetic suction component and the guide cover body. This avoids the problem in the prior art where the ventilation vent guide cover is installed at the ventilation vent by magnetic attraction. Due to the poor attraction force of the existing magnets, it is easy for the vent guide cover to fall off or be accidentally knocked off. After falling, the magnet will fall outside the ventilation vent guide cover, which can easily cause the ventilation vent guide cover to be broken or the magnet to be broken, affecting the normal use of the ventilation vent guide cover and causing the user to be unable to use it normally.

The limiting pin 5 and the pin hole 7 are interference-fitted to fix the limiting pin 5 in the limiting groove 6. There are two limiting pins 5 located on both sides of the magnetic attraction component 4. The diameter of the limiting groove 6 is larger than the diameter of the limiting pin 5.

[0037] A positioning block 8 is provided on the inner peripheral wall of the placement groove 3, and a positioning groove 9 is provided on the magnetic suction component 4.

In this embodiment, the upper end of the outer peripheral surface of the first air deflector 12 is provided with six first protrusions 14. Of course, in addition to six first protrusions 14, there can also be three, four or five. The six first protrusions 14 are spaced apart along the sliding direction. There is a gap between the six first protrusions 14 and the outer peripheral wall of the first air deflector 12 to form a first groove 15. The lower end of the outer peripheral surface of the first air deflector 12 is provided with six second protrusions 16. Of course, in addition to six second protrusions 16, there can also be three, four or five. The six second protrusions 16 are spaced apart along the sliding direction. There is a gap between the six second protrusions 16 and the outer peripheral wall of the first air deflector 12 to form a second groove 17. The first groove 15 and the second groove 17 are arranged opposite to each other to form a sliding groove that matches the second air deflector 13. The second air deflector 13 is slidably disposed in the sliding groove, so that the second air deflector 13 is slidably disposed on the first air deflector 12.

Then, place the limiting pin 5 into the pin hole 7, tap the limiting pin 5, and make the limiting pin 5 and the pin hole 7 interference fit. Since the diameter of the limiting groove 6 is larger than that of the limiting pin 5, the magnetic component has a certain floating space in the valve placement groove 3. The magnetic component 4 can protrude from the bottom surface of the placement groove 3 and contact the ventilation vent. The installation of the magnetic component and the magnetic component on the second vent cover 13 is completed by the above steps.

[0042] In use, first adjust the first hood 12 and the second hood 13 according to the length of the vent. Slide the first hood 12 and the second hood 13 to adjust to the desired position. Then, select the installation method of the guide hood body 1 according to the material of the vent. When the vent is made of iron, it can be installed by magnetic adsorption. When the vent is made of aluminum, it can be installed by self-adhesive bonding. When the vent is made of wood, the guide hood body 1 can be fixed to the vent by using the mounting holes 11 and screws. In this case, the guide groove 2 on the guide hood body 1 is set at the vent to change the air outlet direction of the vent.
