Description

[Technical Field]

[0001] This application relates to the field of bladeless fan technology, and more particularly to a bladeless fan with multiple adjustable air outlets. [Background Technology]

[0002] Bladeless fans increase airflow by expelling air through the air outlet of the duct, and are favored by consumers for their safety, cleanliness, and aesthetic appeal.

[0003] For example, the applicant previously applied for a utility model patent, publication number CN218882592U, entitled "A Bladeless Fan." This patent effectively solved the technical problem of controlling the temperature of the blown air, and the air outlet shell could swing up and down and rotate with the air inlet to adjust the blowing angle. However, during use, the following problems were found: although the angle of the air outlet shell is adjustable, the airflow can only blow in one direction, resulting in a single-direction airflow that cannot adequately meet consumer needs, thus reducing the product's practicality.

[0004] Therefore, it is necessary to design a bladeless fan with multiple adjustable air outlets to meet the needs of consumers. [Summary of the Invention]

[0005] The purpose of this application is to provide a bladeless fan with multiple adjustable air outlets. By incorporating air guide housings within two vertical bases, and air outlets on both the front and rear sides of the air guide housings, the bladeless fan of this product has four air outlets, enabling multi-outlet airflow. Furthermore, an arc-shaped baffle is installed within a vertical circular hole inside the air guide housing. Driven by a mechanism, the arc-shaped baffle rotates, blocking one of the transition holes, thus exposing only one transition hole, or simultaneously exposing both transition holes. This allows the operating state of the air outlets to be adjusted according to the user's needs, greatly improving the product's practicality.

[0006] This application is achieved through the following technical solution:

[0007] A multi-outlet, adjustable bladeless fan includes a base, an air inlet seat, and an air outlet shell. The air inlet seat is mounted on the base. The air outlet shell has an n-shaped structure, including two symmetrically arranged vertical seats and a horizontal seat connected to the upper ends of the two vertical seats. The lower ends of the two vertical seats are connected to the air inlet seat. An air guide shell is provided in each of the two vertical seats. A vertical circular hole is provided in the middle of the air guide shell. The lower end of the vertical circular hole is an air inlet. Transition through holes are symmetrically arranged on the front and rear sides of the vertical circular hole. Air outlets are provided on the front and rear sides of the air guide shell and are connected to the transition through holes. The air outlets extend out of the front and rear sides of the vertical seats. An arc-shaped baffle and a drive mechanism for driving the arc-shaped baffle to rotate are rotatably arranged in the vertical circular hole. The arc-shaped baffle can rotate against the inner wall of the vertical circular hole and can expose one of the transition through holes on both sides, or can expose both transition through holes simultaneously.

[0008] As described above, a multi-outlet and adjustable bladeless fan includes a drive mechanism comprising a motor disposed on the upper end of the air guide shell, wherein the output shaft of the motor extends into a vertical circular hole and is connected to an arc-shaped baffle.

[0009] As described above, a bladeless fan with multiple air outlets and adjustable features symmetrically arranged air guide plates at the lower end of the air inlet.

[0010] As described above, in a multi-outlet and adjustable bladeless fan, the cross-sectional shape of the air guide shell is a flared structure with the width gradually decreasing from the transition through hole to the air outlet.

[0011] As described above, a bladeless fan with multiple air outlets and adjustable features an electric heating element installed inside the vertical circular hole.

[0012] As described above, in a multi-outlet and adjustable bladeless fan, the air inlet is rotatably mounted on the upper surface of the base.

[0013] As described above, in a multi-outlet and adjustable bladeless fan, a connecting cylinder is provided on the inner side of the lower end of both vertical seats, and the connecting cylinder is oscillating back and forth on the air inlet seat.

[0014] As described above, in a bladeless fan with multiple adjustable air outlets, the air inlet base is a cylindrical structure with an open top, and through holes are densely arranged on the front and rear walls.

[0015] As described above, a bladeless fan with multiple air outlets and adjustable features a counterweight within the base.

[0016] Compared with the prior art, this application has the following advantages:

[0017] 1. By setting air guide shells in two vertical seats, and air outlets on both the front and rear sides of the air guide shells, the bladeless fan of this product has four air outlets, realizing multi-outlet air blowing.

[0018] 2. In addition, an arc-shaped baffle is installed in the vertical circular hole inside the air guide housing. The arc-shaped baffle is driven to rotate by the drive mechanism, so that the arc-shaped baffle blocks one of the transition through holes, that is, only one transition through hole is exposed, or both transition through holes on both sides are exposed at the same time. Thus, the working state of the air outlet can be adjusted according to the user's needs, which greatly improves the practicality of the product. [Attached Image Description]

Detailed Implementation Methods

[0025] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] like Figures 1 to 5As shown in the figure, this application proposes a multi-outlet adjustable bladeless fan, including a base 1, an air inlet seat 2, and an air outlet shell 3. The air inlet seat 2 is mounted on the base 1. The air outlet shell 3 has an n-shaped structure, including two symmetrically arranged vertical seats 4 and a horizontal seat 5 connected to the upper ends of the two vertical seats 4. The lower ends of the two vertical seats 4 are connected to the air inlet seat 2. An air guide shell 6 is provided in each of the two vertical seats 4. A vertical circular hole 7 is provided in the middle of the air guide shell 6, and the lower end of the vertical circular hole 7 is for airflow. The inlet 8 has transition through holes 9 symmetrically arranged on the front and rear sides of the vertical circular hole 7. The air guide shell 6 has air outlets 10 connected to the transition through holes 9 on both the front and rear sides. The air outlets 10 extend out of the front and rear sides of the vertical seat 4. An arc-shaped baffle 11 and a driving mechanism for rotating the arc-shaped baffle 11 are rotatably arranged inside the vertical circular hole 7. The arc-shaped baffle 11 can rotate against the inner wall of the vertical circular hole 7 and can expose one of the transition through holes 9 on both sides, or can expose both transition through holes 9 on both sides at the same time.

[0027] In this invention, by providing air guide shells 6 in the two vertical seats 4, and providing air outlets 10 on both the front and rear sides of the air guide shells 6, the bladeless fan of this product has four air outlets, realizing multi-outlet air blowing.

[0028] In addition, an arc-shaped baffle 11 is provided in the vertical circular hole 7 inside the air guide shell 6. The arc-shaped baffle 11 is driven to rotate by the drive mechanism, so that the arc-shaped baffle 11 blocks one of the transition through holes 9, that is, only one transition through hole 11 is exposed, or the transition through holes 11 on both sides are exposed at the same time. Thus, the working state of the air outlet can be adjusted according to the user's needs, which greatly improves the practicality of the product.

[0029] Furthermore, the driving mechanism includes a motor 21 disposed on the upper end of the air guide shell 6, the output shaft of the motor 21 extending into the vertical circular hole 7 and connected to the arc-shaped baffle 11.

[0030] See also Figure 3 As shown, the arc-shaped baffle 11 blocks one of the transition through holes 9, that is, only one transition through hole 11 is exposed, so that the airflow enters the vertical circular hole 7 from the air inlet 8, then enters the exposed transition through hole 11, and finally blows out from the air outlet 10.

[0031] See Figure 4 As shown, the arc-shaped baffle 11 exposes the transition holes 11 on both sides at the same time, so that the airflow enters the vertical circular hole 7 from the air inlet 8, and then enters the transition holes 11 on both sides at the same time, and finally blows out from the air outlets 10 on both sides respectively.

[0032] In order to concentrate the airflow into the vertical circular hole 7, air guide plates 31 are symmetrically arranged at the lower end of the air inlet 8.

[0033] Furthermore, the cross-sectional shape of the air guide shell 6 is a flared structure with the width gradually decreasing from the transition through hole 9 to the air outlet 10.

[0034] In this invention, an electric heating tube 51 is provided inside the vertical circular hole 7, so that heat is generated through the electric heating tube 51, and hot air can be blown out, thereby improving the practicality of the product.

[0035] Furthermore, the air inlet seat 2 is rotatably mounted on the upper surface of the base 1.

[0036] Furthermore, a connecting cylinder 71 is provided on the inner side of the lower end of each of the two vertical seats 4. The connecting cylinder 71 is swaying back and forth on the air inlet seat 2, thereby adjusting the angle of the air outlet to further meet the needs of consumers.

[0037] In this invention, the air inlet seat 2 is a cylindrical structure with an open top, and through holes 81 are densely arranged on the front and rear walls to allow air to enter the air inlet seat 2 better.

[0038] To improve the stability of the product, a counterweight is provided inside the base 1.
