Description

Technical Field

[0001] This utility model belongs to the field of double-headed umbrella technology and relates to a spray cooling structure for a double-headed umbrella. Background Technology

[0002] As people's quality of life continues to improve, their requirements for outdoor equipment are also increasing to enhance comfort during outdoor activities. Currently, Roman umbrellas are commonly used to improve sunshade, but their shading space is limited. Therefore, double-headed umbrellas are used to provide more shade. However, when the outdoor temperature is high, the temperature under the double-headed umbrella also rises. To cool down the umbrella, a misting system is installed on it.

[0003] For example, Chinese patent application [Patent Application No.: 202011252085.4] discloses a conveniently replaceable disinfectant spray folding umbrella, including an umbrella body, the umbrella body including a telescopic umbrella pole, a nozzle connected to the upper end of the telescopic umbrella pole, an umbrella handle connected to the lower end of the telescopic umbrella pole, a bottle body detachably connected to the umbrella handle, a connecting pipe connecting the nozzle and the bottle body, and a pressure pump set on the umbrella handle, and also includes a coiling device for coiling the connecting pipe.

[0004] The above structure is a folding umbrella, which needs to be moved by holding the handle. Therefore, the connecting tube needs to be extended and retracted. In order to facilitate the extension and retraction of the connecting tube, a major processing improvement was made to the original folding umbrella, and a coiling device was added. This resulted in a large improvement cost for the folding umbrella. In addition, the connecting tube needs to be coiled on the coiling device, which increases the difficulty of installation. This makes the processing cost high and the installation difficult. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a spray cooling structure for a double-headed umbrella. The technical problem this utility model aims to solve is: how to address the issues of high processing costs and difficult installation of existing umbrella spray cooling structures.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A spray cooling structure for a double-headed umbrella includes a hollow upright pole, a frame slidably connected to the hollow upright pole, an umbrella fabric on the frame, a main upper umbrella plate located in the middle of the umbrella fabric at the top of the hollow upright pole, and two auxiliary upper umbrella plates extending outwards from the left and right sides of the umbrella frame. The spray cooling structure includes a connecting hose; the middle or lower end of the hollow upright pole has a clearance inlet for the connecting hose to enter the inner cavity of the hollow upright pole, and the upper end has a clearance outlet for the connecting hose to exit the inner cavity of the hollow upright pole; a water pump nozzle is fixedly connected to the main upper umbrella plate and / or the auxiliary upper umbrella plate; the water outlet of the water pump nozzle is located on the upper side of the umbrella fabric; and the water pump nozzle is connected to the water outlet of the connecting hose.

[0008] The double-headed umbrella has two secondary upper umbrella plates on its frame and a main upper umbrella plate at the top of the hollow upright. The umbrella frame is covered with an umbrella fabric, with the main upper umbrella plate located in the middle of the fabric. A water pump nozzle is installed on the main upper umbrella plate, also located in the middle of the fabric. A clearance inlet is located in the middle or lower end of the hollow upright, and a clearance outlet is located at the upper end. A connecting hose passes through the inner cavity of the hollow upright. When cooling of the umbrella fabric is required, the connecting hose can be connected to a water pump or an external water connector, thus supplying water to the water pump nozzle. Water is sprayed from the water pump nozzle, whose outlet is located on the upper side of the umbrella fabric, achieving cooling of the upper side of the fabric. This structure, with a clearance inlet in the middle or lower end of the hollow upright and a clearance outlet at the upper end, facilitates the installation of the connecting hose. Furthermore, the hollow uprights do not extend, retract, or move relative to each other during use. Therefore, it is only necessary to thread the connecting hose through the hollow uprights to minimize the exposed area of ​​the connecting hose during use, thereby ensuring the stability of the connecting hose. To increase the cooling effect, water pump nozzles can be installed on both the main and auxiliary upper umbrella discs of the double-headed umbrella, thereby increasing the cooling effect and the cooling area of ​​the umbrella surface. Based on the original double-headed umbrella, only the clearance inlet and outlet are opened, and the water pump nozzles are installed on the main and / or auxiliary upper umbrella discs. Then, the connecting hose is connected to the water pump or external water connector. The improvement is minor, reducing processing costs. During installation, the connecting hose is directly threaded through the upright, and then the water pump and water pump nozzles are installed, making installation convenient.

[0009] In the above-mentioned double-headed umbrella spray cooling structure, the lower part of the hollow upright is connected to a water pump mounting base by fasteners. A water pump is installed on the water pump mounting base, and the water pump mounting base is located below the clearance inlet.

[0010] By setting up a water pump mounting base, the impact of water pump vibration on the hollow upright is reduced. Furthermore, by placing the water pump mounting base below the inlet, the water in the connecting hose can flow more smoothly and stably to the water pump nozzle when pumping, thus improving the stability of the spray cooling structure.

[0011] In the above-mentioned double-headed umbrella spray cooling structure, the water pump nozzle has a flexible steering hose that is inserted into the main upper umbrella disc and / or the auxiliary upper umbrella disc.

[0012] The design of the steering hose makes it easier to adjust the direction of the water pump nozzle and control the spray direction.

[0013] In the above-mentioned double-headed umbrella spray cooling structure, the main upper umbrella plate is provided with a main umbrella cap, the main umbrella cap can be provided with multiple mounting holes, the water pump nozzle is provided with multiple nozzles, and the water pump nozzle's deflecting hose can be inserted into the corresponding mounting hole.

[0014] Multiple water pump nozzles can be installed on the main umbrella cap. These nozzles can be configured to bend and spray water around the umbrella surface, achieving multi-angle water spraying on the main umbrella cap and improving the cooling effect of the mist cooling structure.

[0015] The steering hose can be connected to the mounting hole with a tight fit, or it can be connected using a snap-fit ​​structure, such as a slot and a block.

[0016] In the above-mentioned double-headed umbrella spray cooling structure, the upper umbrella plate is equipped with the aforementioned water pump nozzle, and the connecting hose is connected to two connecting pipes that communicate with the water pump nozzles on the upper umbrella plate.

[0017] Water pump nozzles can also be installed on the upper umbrella disc, allowing the water pump nozzles to spray a larger area on the umbrella surface, further improving the spraying effect of the water pump nozzles, thereby enhancing the mist cooling structure.

[0018] In the above-mentioned double-headed umbrella spray cooling structure, the spray cooling structure also includes a water container that can be placed on the ground and a water inlet pipe with one end inserted into the water container, and the other end of the water inlet pipe is connected to the inlet of a water pump.

[0019] In actual use, once the double-headed umbrella is opened, it basically does not move. At this time, the water container can be placed on the ground, one end of the water inlet pipe is inserted into the water container, and the other end is connected to the water pump inlet. The water pump will not move up and down with the hollow pole, and the other end of the water inlet pipe can be stably connected to the water pump, which facilitates the use of water for the spray cooling structure outdoors.

[0020] Compared with existing technologies, the spray cooling structure of this double-headed umbrella has the following advantages: By providing a clearance inlet at the middle or lower end of the hollow upright and a clearance outlet at the upper end, it facilitates the installation of the connecting hose. Furthermore, since the hollow upright does not extend, retract, or move relative to the user during use, the connecting hose only needs to be threaded through the hollow upright, minimizing the exposed area of ​​the hose and ensuring its stability. To enhance the cooling effect, water pump nozzles can be installed on both the main and auxiliary upper umbrella discs, increasing the cooling effect and the cooling area of ​​the umbrella surface. The improvement to the original double-headed umbrella is minimal, only requiring the installation of clearance outlets and the water pump nozzles on the main and / or auxiliary upper umbrella discs, followed by connecting the connecting hose to the water pump or external water connector. This reduces processing costs. Installation is also convenient, as the connecting hose is simply threaded through the upright, followed by the installation of the water pump and nozzles.

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] Example 1

[0034] like Figure 1 and Figure 3 As shown, the spray cooling structure of this double-headed umbrella includes a hollow upright pole 1, a frame 2 that is slidably connected to the hollow upright pole 1 along the vertical direction, an umbrella cloth 3 that is provided on the umbrella frame 2, a main upper umbrella plate 11 located in the middle of the umbrella cloth 3 at the top of the hollow upright pole 1, and two auxiliary upper umbrella plates 21 that extend outward from the left and right sides of the umbrella frame 2.

[0035] Specifically, such as Figure 1-6 As shown, this spray cooling structure includes a connecting hose 4. The hollow pole 1 has a clearance inlet 12 at the middle or lower end for the connecting hose 4 to enter the inner cavity of the hollow pole 1, and a clearance outlet 14 at the upper end for the connecting hose 4 to exit the inner cavity of the hollow pole 1.

The connection hose 4 is inserted through the hollow pole 1, which does not extend or move relative to the hollow pole 1 during use. Therefore, it is only necessary to insert the connection hose 4 inside the hollow pole 1 to reduce the exposed area of ​​the connection hose 4 during use, thereby ensuring the stability of the connection hose 4. In order to increase the cooling effect, water pump nozzles 5 can be installed on both the main upper umbrella plate 11 and the secondary upper umbrella plate 21 of the double-headed umbrella, thereby increasing the cooling effect and the cooling area of ​​the umbrella surface. Based on the original double-headed umbrella, only the clearance inlet 12 and clearance outlet 14 are opened, and the water pump nozzles 5 are installed on the main upper umbrella plate 11 and / or the secondary upper umbrella plate 21. Then, the connection hose 4 is connected to the water pump 7 or the external water connector. The improvement is small, reducing the processing cost. During installation, the connection hose 4 is directly inserted into the pole, and then the water pump 7 and the water pump nozzles 5 are installed, making the installation convenient.

[0037] like Figure 1 , Figure 4 , Figure 6 and Figure 10 As shown, the lower part of the hollow pole 1 is connected to a water pump mounting base 6 by fasteners. A water pump 7 is installed on the water pump mounting base 6, and the water pump mounting base 6 is located below the relief inlet 12. The water pump nozzle 5 has a bendable steering hose 51 that is inserted into the main upper umbrella disc 11 and / or the auxiliary upper umbrella disc 21.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, this spray cooling structure also includes a water container 9 that can be placed on the ground and a water inlet pipe 10 with one end inserted into the water container 9. The other end of the water inlet pipe 10 is connected to the inlet of the water pump 7.

The water pump nozzle 5 is provided with multiple holes, and the directional hose 51 of the water pump nozzle 5 can be inserted into the corresponding mounting hole 13a.

[0041] Example 3

[0042] The content of this embodiment is basically the same as that of Embodiment 1, except that: Figure 9 As shown, each of the upper umbrella discs 21 is equipped with a water pump nozzle 5, and the connecting hose 4 is connected to two connecting pipes 8 that communicate with the water pump nozzles 5 on the upper umbrella discs 21.

[0043] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
