Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a vertical fan with high-speed supercharging. Background Art

[0002] In traditional technologies, fans are widely used in people's daily lives. There are various types of fans suitable for different occasions. The Chinese utility model patent with the authorization announcement number CN221033231U discloses a three-dimensional oscillating fan, which includes a machine head, a column pipe, a chassis, an outer bracket, a left and right oscillating mechanism, and an up and down oscillating mechanism. The chassis is arranged at the bottom end of the column pipe, the outer bracket is arranged at the top end of the column pipe, the left and right oscillating mechanism is connected to the outer bracket, the machine head is arranged on the outer bracket, the up and down oscillating mechanism is connected to the machine head, and the up and down oscillating mechanism is connected to the outer bracket. By providing the left and right oscillating mechanism, the left and right shaking of the machine head can be realized; by providing the up and down oscillating mechanism, the up and down shaking of the machine head can be realized, meeting the air supply requirements of multiple angles;

[0003] The air supply range of this vertical fan is expanded through shaking and the white head, meeting people's needs.

[0004] However, a net cover is usually installed outside the fan blades of a vertical fan to disperse and guide the air flow and increase the coverage area of the air flow. In existing net covers, either a wire drawing net is simply used to form the net cover, which only serves a protective function, or the air flow direction is output around through the flow guiding plates on the net cover. Although the air supply angle is increased, people in the middle position feel a decrease in the air volume, affecting the user experience.

[0005] The Chinese utility model patent with the authorization announcement number CN215214143U discloses a net cover for a fan, specifically discloses a net cover for a fan, which includes a net cover outer ring and a net cover inner ring. A plurality of long arc-shaped plates and short arc-shaped plates are evenly distributed along the circumference between the net cover outer ring and the net cover inner ring. One end of the long arc-shaped plate is connected to the inner side of the net cover outer ring, and the other end is connected to the outer side of the net cover inner ring. One end of the short arc-shaped plate is connected to the inner side of the net cover outer ring, and the plate body of the short arc-shaped plate is connected to the long arc-shaped plate through two connecting rings. The length of the short arc-shaped plate is two-thirds of the length of the long arc-shaped plate. First connection holes and second connection holes are respectively opened on the plate body of the long arc-shaped plate, and third connection holes and fourth connection holes are respectively opened on the plate body of the short arc-shaped plate. The first connection hole corresponds to the third connection hole, and the second connection hole corresponds to the fourth connection hole; The utility model provides a net cover for a fan to solve the problems of poor air supply effect and too dispersed air flow of the net cover.

[0006] This wire mesh cover only guides the direction of the air flow output from the wire mesh cover, but cannot guide the air flow inside the wire mesh cover. As a result, due to the inconsistent output directions of the air flow inside the wire mesh cover, a small amount of air flow blows out from other parts of the fan, thereby reducing the air volume blown out from the wire mesh cover.

Detailed implementation manners

[0035] To further illustrate the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific implementation manners, structures, features and their effects according to the present utility model as follows.

[0036] As Figures 1-7 shown, the following embodiment discloses a vertical fan with high-speed pressurization.

[0037] A vertical fan with high-speed pressurization includes a base 100 and a head 300 connected by a vertical rod 200, and the vertical rod 200 and the head 300 are provided with an up-and-down swinging mechanism and a left-and-right swinging mechanism;

[0038] The head 300 includes a fan blade 330 driven by a motor 310, and a rear grille 320 and a front grille 340 covering the outside of the fan blade 330;

[0039] It is characterized in that: the rear grille 320 has an open side and a closed side, and the open side is buckled with the front grille 340 to form a complete housing with a cavity;

[0040] An air inlet groove 321.1 is arranged on the rear grille 320, and an air outlet groove 341 is arranged on the front grille 340;

[0041] The rear grille 320 is provided with a pressurization and diversion structure.

[0042] The above is the basic solution of this embodiment.

[0043] Specifically referring to Figure 1 and Figure 2 shown, a circuit is arranged in the base 100, and the up-and-down swinging mechanism and the left-and-right swinging mechanism are controlled by wires to swing and shake the head 300;

[0044] In this embodiment, the vertical rod 200 can be set as a telescopic structure to meet the needs of consumers for the air outlet position;

[0045] When the fan is started, the electrode operates, driving the fan blade 330 to rotate. The fan blade 330 drives the surrounding air to form an air flow, which is blown out from the air outlet groove 341 on the front grille 340. The air inlet groove 321.1 of the rear grille 320 is used for air inlet to supplement the air in the head 300, forming an air flow exchange inside and outside the head 300.

[0046] In this embodiment, the up-and-down swinging mechanism and the left-and-right swinging mechanism of the vertical fan are the same as those of the existing fans, and will not be elaborated here.

[0047] When the air inside the head 300 is driven by the fan blades 330 to form an air current, the output direction is towards the side of the air outlet groove 341. However, due to the rotational effect of the fan blades 330, the direction of the formed air current is not uniform. Therefore, part of the air current is output from other positions of the head 300;

[0048] In this embodiment, a pressurizing and guiding structure is provided to guide the generated air current inside the head 300, so that the air current can form a uniform air current output towards the air outlet groove 341; at the same time, the air current is pressurized to increase the speed when the air current is output from the air outlet groove 341, and the air outlet efficiency is improved.

[0049] Specifically, in this embodiment, the rear net cover 320 includes an integrally formed rear end cover 321 and a side surround 322, and the side surround 322 is provided at the outer edge of the rear end cover 321;

[0050] The pressurizing and guiding structure is a guiding rib 322.1 provided on the inner wall of the side surround 322.

[0051] Specifically refer to Figure 3 As shown, the rear net cover 320 is set as a housing with an open front end, and the air outlet groove 341 is provided on the rear end cover 321, corresponding to the position of the air outlet groove 341 on the front net cover 340, so that the moving path of the air current in the head 300 is a straight line;

[0052] A through hole 321.2 is provided on the rear end cover 321, and the output shaft of the motor 310 extends into the head through the through hole 321.2 and is connected to the fan blades 330.

[0053] The guiding rib 322.1 is provided on the inner wall of the side surround 322 and is matched with the position of the fan to guide the air current with inconsistent directions formed on the side of the fan, so that the air current in this area has a unified output direction.

[0054] Preferably, in this embodiment, the length direction of the guiding rib 322.1 is consistent with the moving direction of the air current in the head 300.

[0055] Specifically refer to Figure 4 As shown, the setting direction of the guiding rib 322.1 is consistent with the moving direction of the air current, that is, from the rear end cover 321 towards the front net cover 340; a guiding groove is formed between adjacent guiding ribs 322.1. When the air current with inconsistent directions hits the guiding rib 322.1, the moving direction is changed and the air current is output along the guiding groove. The air current directions in multiple guiding grooves are all towards the air outlet groove 341, thus forming multiple air currents with consistent directions;

[0056] The multiple air currents in the guiding groove are output from the air outlet groove 341 together with the main air current of the head 300, so as to have the effect of a large air volume.

[0057] In this embodiment, the flow guiding rib 322.1 has another function, which is to disperse the chaotic air flow, weaken the locally over-strong air flow, and make the irregular air flow form a regularly flowing air flow in the flow guiding groove, so that the output air flow is more uniform.

[0058] Specifically, in this embodiment, an end of the flow guiding rib 322.1 near the rear end cover 321 is provided with a flow guiding slope 322.11; the end face of the flow guiding slope 322.11 is set as an inclined plane.

[0059] Refer to Figure 5 As shown, the flow guiding slope 322.11 is arranged at the starting end of the flow guiding groove and is connected to the inner end face of the side wall 322 through an inclined plane. On the one hand, it ensures the strength of the flow guiding rib 322.1, and on the other hand, a small amount of turbulent air flow can enter the flow guiding groove through the inclined plane, improving the flow guiding efficiency.

[0060] Preferably, in this embodiment, the thickness of the flow guiding rib 322.1 is not greater than the thickness of the side wall 322.

[0061] Specifically refer to Figure 6 As shown, the flow guiding rib 322.1 and the inner wall of the side wall 322 are integrally formed, and the thickness of the flow guiding rib 322.1 is not greater than the thickness of the side wall 322. The purpose is to make the strength of the flow guiding rib 322.1 less than the strength of the side wall 322. In this way, when the turbulent air flow moves in the flow guiding groove, it only has an impact when hitting the flow guiding rib 322.1, ensuring the structural consistency of the side wall 322.

[0062] In this embodiment, to ensure the outer shape structure of the head 300, a plurality of buckling parts 322.2 are convexly provided on the inner wall of the front part of the side wall 322, and the front mesh cover 340 is embedded into the side wall 322 and buckled with the buckling parts 322.2.

[0063] An installation ring 342 is provided on the front mesh cover 340 facing the rear mesh cover 320, and a buckling groove 342.1 capable of accommodating the buckling part 322.2 to slide in is provided on the outer circumference of the installation ring 342.

[0064] Specifically refer to Figure 4 and Figure 7 As shown, the buckling part 322.2 is a convex block provided on the inner wall of the side wall 322, and the protruding direction is towards the center of the side wall 322;

[0065] The installation ring 342 is convexly provided on the inner end face of the front mesh cover 340, and the buckling groove 342.1 is provided on the circumferential surface of the installation ring 342;

[0066] The number of the buckling parts 322.2 and the buckling grooves 342.1 is the same.

[0067] Preferably, to ensure the aesthetic appearance of the head 300, the outer diameter of the mounting ring 342 is smaller than the outer diameter of the front cover; and the outer diameter of the front mesh cover 340 is the same as the outer diameter of the side enclosure 322.

[0068] During installation, the front mesh cover 340 is embedded into the opening of the rear mesh cover 320, that is, embedded into the inner side of the front end of the side enclosure 322. The side enclosure 322 wraps the outer periphery of the front mesh cover 340, so that the front mesh cover 340 and the rear mesh cover 320 form a complete outer shape.

[0069] Rotate the front mesh cover 340 so that the buckle portion 322.2 is snapped into the buckle groove 342.1, and the assembly is completed.

[0070] Preferably, in this embodiment, to ensure the smooth screwing between the buckle portion 322.2 and the buckle groove 342.1, a guiding surface 342.11 is provided on the groove wall of the buckle groove 342.1, so that the opening of the buckle groove 342.1 along the sliding direction of the buckle portion 322.2 forms a reduced opening.

[0071] Based on the above settings, even if the front mesh cover 340 is not installed in place, during rotation, the guiding surface 342.11 contacts the buckle portion 322.2 and applies a force to the buckle portion 322.2. The reaction force of the buckle portion 322.2 on the guiding surface 342.11 causes the guiding surface 342.11 to move, so that the front mesh cover 340 moves towards the inner side of the side enclosure 322, so that the front mesh cover 340 is assembled in place when tightened.

[0072] Embodiment 2

[0073] This embodiment is an improvement based on Embodiment 1. Its purpose is to discharge a very small amount of unguided air flow, so that the air flow output from the air outlet groove 341 is more uniform. The specific implementation method is as follows:

[0074] Refer to Figure 4 and Figure 5 As shown, strip-shaped grooves 322.3 are arranged on the side enclosure 322 along the air flow movement direction, and the flow guiding ribs 322.1 are located between two adjacent strip-shaped grooves 322.3.

[0075] In this embodiment, the strip-shaped grooves 322.3 are located in the area of the flow guiding grooves.

[0076] Among the turbulent air flows formed around the fan blades 330, a very small amount of air flow does not contact the flow guiding ribs 322.1, so that its movement direction and speed cannot be changed. This very small amount of turbulent air flow can be output from the side of the head 300 through the strip-shaped grooves 322.3 to avoid disturbing the output air flow.

[0077] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model by using the technical content disclosed above. However, as long as it does not depart from the content of the technical solution of the present utility model, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
