Description

[Technical Field]

[0001] The present utility model relates to the technical field of bladeless cooling and heating fans, and specifically relates to a bladeless cooling and heating fan with an adjustable air blowing direction. [Background Art]

[0002] An existing bladeless cooling and heating fan, for example the bladeless cooling and heating fan of model number TP-09, is composed of a main body, a base and an air blowing assembly, wherein a fan unit and a heating element are provided inside the main body. Air is drawn in from an air intake port by the fan unit, heated by the heating element, and then blown out at high speed from an annular air outlet, thereby realizing a heating function. In order to meet air blowing requirements in different usage scenarios, some bladeless cooling and heating fans achieve limited adjustment of the air blowing direction by automatically rotating themselves.

[0003] However, the above-mentioned existing bladeless cooling and heating fans have at least the following drawbacks. The rotary connection structure between the main body and the base generally only rotates around a single axis, so the adjustment range of air blowing in the horizontal direction is limited. When a user wants to adjust the air blowing direction to a position with a large angular difference, it is often necessary to lift the entire device to change the installation direction, which is labor-intensive to operate and cannot achieve air blowing to the target position. In addition, some adjustment mechanisms that adopt gear and rotating shaft structures have complex structures and a large number of parts, which increases manufacturing costs. After long-term rotation use, looseness due to wear is likely to occur, which affects the positioning stability after adjustment. Furthermore, most existing products can only realize adjustment in one direction, either horizontal rotation or vertical oscillation, and it is difficult to simultaneously meet the multi-dimensional air blowing requirements in both horizontal and vertical directions. Therefore, the present utility model provides a bladeless cooling and heating fan with an adjustable air blowing direction. [Summary of the Invention]

[0004] The object of the present utility model is to provide a bladeless cooling and heating fan with an adjustable air blowing direction. [Means for Solving the Problems]

[0005] To achieve the above objective, this utility model provides the following technical solution. A bladeless air conditioning fan with adjustable airflow direction, comprising a bladeless air conditioning fan body, the bottom of which is provided an adjustment structure, the adjustment structure comprising a first base located below the bladeless air conditioning fan body and a second base that fits the first base, the inner wall of the second base being provided with slide grooves distributed in a cross shape, and a slider being slidably connected to the inner wall of the slide grooves.

[0006] As a further invention of this utility model, the bottom of the slider penetrates the slide groove and is fixedly connected to the regulating disc.

[0007] As a further invention of this utility model, the bottom of the first base is spherical, and a groove is provided on the upper surface of the second base, the groove conforming to the shape of the bottom of the first base.

[0008] As a further invention of this utility model, a mounting groove and a positioning pin are provided on the top of the first base, a mounting base is fixedly installed on the bottom of the bladeless cooling and heating fan body, and the mounting base is fixedly connected to the positioning pin.

[0009] As a further feature of this utility model, the mounting base is inserted and connected within the mounting groove and the positioning pin.

[0010] As a further invention of this utility model, the slider is fixedly connected to the first base, and when the slider slides, the first base, the mounting seat, and the bladeless air conditioning fan body slide synchronously within the slide groove. [Effects of the Invention]

[0011] By adopting the above technical solution, the beneficial effects of this utility model compared to conventional technology are as follows:

[0012] 1. This utility model achieves flexible adjustment of the airflow direction of the bladeless cooling and heating fan body through the design of a slide groove and slider. When the bladeless cooling and heating fan body is pressed during use, the bladeless cooling and heating fan body slides along the slider in a cross-shaped slide groove of the second base via the first base, adjusting the bladeless cooling and heating fan body to any position in the horizontal direction (forward, backward, left, or right) to change the airflow direction. Furthermore, since the bottom of the first base is spherical and the top surface of the second base has a groove that fits this spherical shape, when the slider slides to a different position along the slide groove, the spherical bottom of the first base is displaced in the groove at an angle corresponding to the sliding trajectory, synchronously forming different elevation or depression angles of the bladeless cooling and heating fan body. Therefore, by simply pressing the fan, the elevation and depression angles of the airflow direction can be adjusted simultaneously.

[0013] Other advantages, purposes, and features of this utility model will be described to some extent in the specification below, and to some extent will be obvious to those skilled in the art based on the following considerations and studies, or will be taught from the practice of this utility model.

[0015] As shown in the diagram, the components are: 1 bladeless cooling / heating fan body, 2 adjustment structure, 21 first base, 22 second base, 23 slide groove, 24 slider, 25 regulating disc, 26 mounting groove, 27 positioning pin, and 28 mounting base. [Modes for carrying out the invention]

[0016] The specific embodiments of this utility model will be further described below with reference to the attached drawings. It should be noted that these descriptions of embodiments are intended to aid in the understanding of this utility model and do not limit it.

[0017] Furthermore, the technical features of each embodiment of this utility model, as described below, can be combined in any way, as long as they do not contradict each other.

[0018] Referring to the attached drawings 1 to 8, the bladeless air conditioning fan with adjustable airflow direction of this utility model includes a bladeless air conditioning fan body 1, the model number of the bladeless air conditioning fan body 1 is the same as that described in the background art, and this utility model does not relate to any improvement of the internal structure of the bladeless air conditioning fan body 1. An adjustment structure 2 is provided at the bottom of the bladeless air conditioning fan body 1, and the adjustment structure 2 includes a first base 21 located below the bladeless air conditioning fan body 1 and a second base 22 that fits the first base 21, and the inner wall of the second base 22 is provided with slide grooves 23 distributed in a cross shape, and a slider 24 is slidably connected to the inner wall of the slide grooves 23.

[0019] According to the above configuration, the slide grooves 23 are distributed in a cross shape, and specifically include a first groove extending laterally along the inner wall of the second base 22 and a second groove extending longitudinally. The first groove and the second groove intersect in the central region of the second base 22, forming four sliding directions at 90-degree angles. The slider 24 is slidably coupled in the slide groove 23, and a clearance fit is formed between the outer wall of the slider 24 and the inner wall of the slide groove 23. The slider 24 can reciprocate laterally along the first groove, and can also reciprocate longitudinally along the second groove. The top of the slider 24 is fixedly connected to the bottom of the first base 21. When the slider 24 slides in the slide groove 23, the first base 21 and the bladeless cooling and heating fan main body 1 fixed to the first base 21 move synchronously, thereby displacing the bladeless cooling and heating fan main body 1 relative to the second base 22 in the horizontal direction and changing the air blowing direction (it should be noted that the distribution of the slide grooves 23 crossing in a cross shape in the above embodiment is merely an example, and the specific opening direction of the slide grooves 23 is not limited to the cross-intersection form. A person skilled in the art can form the slide grooves 23 in any extending direction on the inner wall of the second base 22 according to actual requirements for adjusting the air blowing angle. When the slider 24 slides along the corresponding slide groove 23, position adjustment in the corresponding direction can be realized as long as the first base 21, the mounting seat 28 and the bladeless cooling and heating fan main body 1 are moved synchronously, and the working principle is the same as that of the above embodiment. Therefore, under the design concept of the present utility model, any equivalent modification or alternative solution that realizes position adjustment of the bladeless cooling and heating fan main body 1 by forming slide grooves 23 and making the slider 24 slide should be included in the protection scope of the present utility model).

[0020] As shown in Figure 5, the bottom of the slider 24 passes through the slide groove 23 and is fixedly connected to the restricting disk 25.

[0021] According to the above solution adopted: after the bottom of the slider 24 extends downward and passes through the slide groove 23, it protrudes from the bottom surface of the second base 22, the restriction disk 25 is fixedly connected to the end of the protruding end of the slider 24, and the restriction disk 25 is located below the bottom surface of the second base 22. The outer diameter of the restriction disk 25 is larger than the groove width of the slide groove 23, and the restriction disk 25 cannot pass through the slide groove 23 and enter the interior of the second base 22. Therefore, when the first base 21 receives an upward external force, the edge of the restriction disk 25 abuts against the periphery of the end portion of the slide groove on the bottom surface of the second base 22, blocking the slider 24 from sliding further upward, and preventing the slider 24 from falling off from the slide groove 23. At the same time, when the slider 24 slides along the slide groove 23 to the end limit position of the slide groove 23, the end surface of the slider 24 abuts against the groove wall at the end of the slide groove 23, blocking the slider 24 from further horizontal sliding. The restriction disk 25 slides synchronously with the slider 24, and does not affect the normal sliding of the slider 24 within the effective stroke range of the slide groove 23.

[0022] During assembly, first place the first base 21 on the upper end of the second base 22, and fit the bottom of the first base 21 into the concave groove on the upper surface of the second base 22. Thereafter, insert the slider 24 upward from the lower end of the second base 22 into the slide groove 23, and adopt clearance fit between the slider 24 and the inner wall of the slide groove 23. Subsequently, fixedly connect the upper end of the slider 24 to the bottom of the first base 21 by means of screw connection or snap-fit connection. At this time, the restriction disk 25 is located below the bottom surface of the second base 22, and since the outer diameter of the restriction disk 25 is larger than the groove width of the slide groove 23, the edge of the restriction disk 25 abuts against the bottom surface of the second base 22, thereby restricting the separation of the first base 21 and the second base 22 in the vertical direction, and maintaining the first base 21 and the second base 22 in a stable connection state. In addition, the slider 24 can reciprocate along the direction of the slide groove 23, thereby synchronously moving the first base 21 on the upper part of the slider 24.

[0023] As shown in Figures 3, 5, 7, and 8, the bottom of the first base 21 is spherical, and a groove is provided on the upper surface of the second base 22, which conforms to the shape of the bottom of the first base 21.

[0024] According to the above configuration, the bottom of the first base 21 has a spherical structure, and its spherical surface is convex downwards. The groove on the upper surface of the second base 22 is an inwardly recessed spherical groove, and the radius of curvature of the spherical groove matches the radius of curvature of the bottom spherical surface of the first base 21. The bottom spherical surface of the first base 21 fits into the spherical groove on the upper surface of the second base 22, and the two form a spherical pair. The first base 21 can swing or rotate in any direction relative to the second base 22 within the groove, thereby enabling the bladeless air-conditioning fan body 1 fixed to the top of the first base 21 to adjust the angle of elevation or depression of the airflow in a vertical plane. At the same time, the groove forms a circumferential restriction on the bottom of the first base 21, preventing the first base 21 from shifting laterally during horizontal sliding or rotation, and ensuring overall stability during the adjustment process.

[0025] As shown in Figure 6, a mounting groove 26 and a positioning pin 27 are provided at the top of the first base 21, and a mounting base 28 is fixedly installed at the bottom of the bladeless air conditioning fan body 1, and the mounting base 28 is fixedly connected to the positioning pin 27.

[0026] According to the above configuration, the mounting groove 26 is a circular recessed groove or irregularly shaped groove opened on the top surface of the first base 21, and the positioning pins 27 are columnar structures protruding from the bottom of the mounting groove 26. There are multiple positioning pins 27, and the multiple positioning pins 27 are distributed at intervals in the circumferential direction of the mounting groove 26. The bottom of the mounting seat 28 is provided with positioning holes that correspond one-to-one with the positioning pins 27. When mounting, the mounting seat 28 is placed in the mounting groove 26 and each positioning pin 27 is inserted into its corresponding positioning hole, thereby restricting the mounting seat 28 in the horizontal direction by the positioning pins 27, achieving circumferential positioning between the mounting seat 28 and the first base 21, and preventing the bladeless cooling and heating fan body 1 from rotating relative to the first base 21 during operation.

[0027] As shown in Figures 4, 5, and 6, the mounting base 28 is inserted and connected into the mounting groove 26 and the positioning pin 27.

[0028] According to the above configuration, the bottom shape of the mounting seat 28 matches the inner wall shape of the mounting groove 26, and the lower part of the mounting seat 28 is fitted into the mounting groove 26. The outer wall of the mounting seat 28 and the inner wall of the mounting groove 26 fit together tightly, and the mounting seat 28 is fixedly connected to the first base 21 by insertion. The bottom surface of the mounting seat 28 abuts against the bottom of the mounting groove 26, and the side surface of the mounting seat 28 abuts against the inner wall of the mounting groove 26. The positioning pin 27 and the positioning hole are arranged in conjunction with each other to restrict both the horizontal and vertical displacement of the mounting seat 28, preventing it from loosening and coming off the first base 21 due to vibrations that occur during the operation of the bladeless cooling and heating fan body 1.

[0029] As shown in Figures 2 and 3, the slider 24 is fixedly connected to the first base 21, and when the slider 24 slides, it causes the first base 21, the mounting seat 28, and the bladeless air conditioning fan body 1 to slide synchronously within the slide groove 23.

[0030] According to the above configuration, when an external force acts on the bladeless air conditioning fan body 1 or the first base 21 and causes it to move horizontally, the slider 24 moves synchronously with the first base 21 and slides along the groove direction of the slide groove 23. The mounting seat 28 is fixedly installed at the bottom of the bladeless air conditioning fan body 1, and the mounting seat 28 is inserted and fixed into the mounting groove 26 and positioning pin 27 of the first base 21. Therefore, the bladeless air conditioning fan body 1, the mounting seat 28, the first base 21, and the slider 24 constitute a single interlocking structure. This interlocking structure slides horizontally along the slide groove 23 relative to the second base 22 under the guidance of the slider 24, thereby adjusting the bladeless air conditioning fan body 1 to the required front-to-back or left-to-right position and enabling flexible adjustment of the airflow direction. When the external force is removed after the adjustment is complete, the interlocking structure is held in the adjusted position by the frictional force between the slider 24 and the inner wall of the slide groove 23, eliminating the need for a separate locking structure.

[0031] Operating principle: When adjusting the airflow direction, a horizontal external force is applied to the bladeless air conditioning fan body 1 according to the actual airflow needs. The slider 24 slides along the groove direction of the slide groove 23 driven by the first base 21, pushing the bladeless air conditioning fan body 1 and sliding the slider 24 along the slide groove 23. The slider 24 synchronizes the sliding of the first base 21, the mounting seat 28, and the bladeless air conditioning fan body 1 to the target position. After the external force is removed, the entire assembly is held in the adjusted position by the frictional force between the slider 24 and the inner wall of the slide groove 23. Because the bottom of the first base 21 is spherical and the upper surface of the second base 22 has a groove that fits the spherical shape, when the slider 24 slides along the slide groove 23 to a different position, the spherical bottom of the first base 21 causes an angular displacement in the groove according to the sliding trajectory, causing the bladeless air conditioning fan body 1 to synchronize and form different angles of elevation or depression. In other words, if the sliding position of the slider 24 within the slide groove 23 is different, the corresponding vertical elevation and depression angle of the bladeless air conditioning fan body 1 will also be different. This enables synchronized adjustment of the vertical airflow angle simultaneously with the horizontal parallel movement adjustment. Finally, the airflow operation is performed, and the bladeless air conditioning fan body 1 is connected to the power supply and started up. The bladeless air conditioning fan body 1 draws in air from the intake port, processes it with the internal heating or cooling element, and then sends it out from the outlet. The air conditioning operation is completed by sending heated or cooled air to the target area in the adjusted direction and angle. The terms front, back, left, right, top, and bottom mentioned above are all based on Figure 1 in the attached drawings of the specification.

[0033] A person skilled in the art can make various changes, modifications, substitutions, and alterations to these embodiments without departing from the principles and spirit of this utility model, and these will still fall within the scope of protection of this utility model.
