Description

Technical Field

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

[0002] As people's quality of life continues to improve, their requirements for outdoor equipment are also increasing in order to enhance the comfort of outdoor activities. Currently, Roman umbrellas are commonly used to improve the sunshade effect. However, when the outdoor temperature is high, the temperature under the Roman umbrella also rises. The current solution is to set up a misting structure on the umbrella to cool the surface.

[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 winding device for winding 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. As a result, a large amount of processing and improvement has been made to the original folding umbrella, resulting in a large improvement cost. In addition, the connecting tube needs to be coiled on the coiling device, which increases the difficulty of installation. This makes both the processing cost and the installation difficult. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a spray cooling structure for Roman umbrellas. The technical problem this invention aims to solve is: how to address the issue of high processing costs and difficult installation of existing spray cooling structures for Roman umbrellas.

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

[0007] A spray cooling structure for a Roman umbrella includes a column and a handrail vertically slidably connected to the column. An inclined tube is hinged to the handrail, and an umbrella frame is hinged to one end of the inclined tube. An umbrella fabric is mounted on the umbrella frame, and an upper umbrella plate is located at the upper end of the umbrella frame. The spray cooling structure includes a connecting hose and a water pump nozzle connected to the upper umbrella plate. Both ends of the inclined tube have clearance holes for the connecting hose to enter or exit the inner cavity of the inclined tube. The water outlet of the connecting hose passes through the inner cavity of the inclined tube and communicates with the water pump nozzle. The water outlet of the water pump nozzle is located on the upper side of the umbrella fabric.

[0008] When in use, Roman umbrellas are typically fixed in place. The connecting hose is inserted into the inner cavity of the slanted tube. The outlet of the connecting hose connects to the water pump nozzle located on the upper umbrella plate. The inlet of the connecting hose can be connected to either the water pump or an external water connector. Therefore, when cooling is needed, water from the external water connector or the water pump is simply passed through the connecting hose and sprayed from the water pump nozzle onto the upper side of the umbrella fabric, achieving cooling of the upper side of the fabric. Because the slanted tube and the upper umbrella plate are hinged regardless of whether the umbrella is open or closed, there is minimal friction between them. The relative displacement allows the connecting hose to simply pass through the inner cavity of the inclined tube and onto the upper umbrella plate, eliminating the need for hose reeling or winding. This simplifies the installation of the spray cooling structure. Furthermore, water supply to the connecting hose can be provided by a water pump or directly connected to an existing external water connector, making water supply more convenient and flexible. The aforementioned structure requires only minor modifications to the inclined tube and upper umbrella plate, such as drilling and installation, to achieve the installation and setup of the spray cooling structure. This reduces the cost of modifying the original Roman umbrella structure while also facilitating the installation of the spray cooling structure.

[0009] In the above-mentioned Roman umbrella spray cooling structure, an upper umbrella cap is fixedly connected to the upper umbrella plate, and an installation hole is opened in the middle of the upper umbrella cap. A flexible fixed hose is fixedly connected to the lower end of the water pump nozzle, and the lower end of the fixed hose is inserted into the installation hole. The fixed hose is connected to the water outlet end of the connecting hose.

[0010] By connecting an upper umbrella cap to the upper umbrella plate and providing mounting holes in the upper umbrella cap, the manufacturing process is made more convenient by simply modifying the upper umbrella cap. Furthermore, the water pump nozzle is connected to the connecting hose via a flexible fixed hose, which can be bent to change the orientation of the water pump nozzle, making the orientation adjustment of the water pump nozzle more convenient. This not only makes the manufacturing process easier but also makes the orientation adjustment of the water pump nozzle more convenient.

[0011] In the above-mentioned spray cooling structure of the Roman umbrella, the lower end of the armrest has a connecting rod that bends downward and slides on the column. A connecting bag is hung on the connecting rod, and a water pump is placed inside the connecting bag. The water pump is connected to the water inlet of the connecting hose.

[0012] By first covering the connecting bag onto the connecting rod before installing the handrail, and then sliding the connecting rod onto the column, the connecting bag can be stably attached to the handrail. This eliminates the need for any structural modifications to the original handrail and allows for the installation of the water pump and the synchronous movement of the water pump and handrail. This reduces processing costs while improving the installation efficiency of the spray cooling structure.

[0013] In the aforementioned spray cooling structure of the Roman umbrella, the aforementioned clearance hole at the end of the inclined tube near the column is opened on the outer wall of the inclined tube.

[0014] The placement of the clearance hole facilitates the installation of the connecting hose without affecting the installation of the slanted tube and other components of the Roman umbrella. This improves the stability of the spray cooling structure installation without compromising the installation of the Roman umbrella itself.

[0015] In the spray cooling structure of the Roman umbrella described above, the opening at the upper end of the inclined tube is one of the aforementioned mounting holes, through which the connecting hose can pass.

[0016] The clearance hole is set as an opening at the upper end of the inclined tube, so that the clearance hole does not require further drilling of the inclined tube, reducing the processing of the original inclined tube and further reducing the processing cost.

[0017] In the aforementioned Roman 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, the other end of which is connected to the inlet of a water pump.

[0018] In actual use, once the Roman 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. When the water pump moves up and down, the other end of the water inlet pipe moves up and down accordingly, which facilitates the use of water for the spray cooling structure outdoors.

[0019] Compared with existing technologies, the spray cooling structure of this Roman umbrella has the following advantages: the connecting hose only needs to be installed on the inclined tube and passed through the upper umbrella plate, without the need for winding or retracting the connecting hose, which facilitates the installation of the spray cooling structure. Furthermore, taking advantage of the Roman umbrella's non-movable nature, the connecting hose only needs to be connected to the water pump or external water connector. The above structure only requires minor improvements to the inclined tube and the upper umbrella plate, such as drilling and installation, to achieve the installation and setup of the spray cooling structure. This reduces the cost of modifying the original Roman umbrella structure while also facilitating the installation of the spray cooling structure. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] like Figure 1 and Figure 2 As shown, the spray cooling structure of this Roman umbrella includes a column 1 and a handrail 2 that is vertically slidably connected to the column 1. An inclined tube 3 is hinged to the handrail 2. One end of the inclined tube 3 is hinged to an umbrella frame 101. An umbrella cloth 102 is provided on the umbrella frame 101. An upper umbrella plate 4 is also provided at the upper end of the umbrella frame 101.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, this spray cooling structure includes a connecting hose 5 and a water pump nozzle 6 connected to the upper umbrella plate 4. Both ends of the inclined tube 3 are provided with clearance holes 31 for the connecting hose 5 to pass into or out of the inner cavity of the inclined tube 3. The water outlet 52 of the connecting hose 5 passes through the inner cavity of the inclined tube 3 and communicates with the water pump nozzle 6. The water outlet of the water pump nozzle 6 is located on the upper side of the umbrella fabric 102.

[0028] When in use, the Roman umbrella is usually fixed in place. The connecting hose 5 is inserted into the inner cavity of the inclined tube 3. The water outlet 52 of the connecting hose 5 is connected to the water pump nozzle 6 located on the upper umbrella plate 4. The water inlet 51 of the connecting hose 5 can be connected to the water pump 7 or to an external water connector. Thus, when water spraying for cooling is needed, water from the external water connector or the water pump 7 is simply sprayed through the connecting hose 5 and out of the water pump nozzle 6 onto the upper side of the umbrella fabric 102, achieving cooling of the upper side of the umbrella fabric 102. Since the inclined tube 3 and the upper umbrella plate 4 are hinged regardless of whether the umbrella is open or closed, the connection between the two... There will be no large relative displacement, so the connecting hose 5 only needs to be inserted into the inner cavity of the inclined tube 3 and onto the upper umbrella plate 4. There is no need to retract the connecting hose 5, which facilitates the installation of the spray cooling structure. Furthermore, the water supply for the connecting hose 5 can be provided by the water pump 7 or directly connected to the existing external water connector, making water supply more convenient and flexible to use. The above structure only requires minor improvements such as drilling and installation to the inclined tube 3 and the upper umbrella plate 4 to realize the installation and setting of the spray cooling structure. This reduces the cost of improving the original Roman umbrella structure while also facilitating the installation of the spray cooling structure.

[0029] like Figure 3 As shown, an upper umbrella cap 41 is fixedly connected to the upper umbrella plate 4. An installation hole 41a is opened in the middle of the upper umbrella cap 41. A bendable fixed hose 61 is fixedly connected to the lower end of the water pump nozzle 6. The lower end of the fixed hose 61 is inserted into the installation hole 41a. The fixed hose 61 is connected to the water outlet 52 of the connecting hose 5.

[0030] like Figure 2 and Figure 4 As shown, the lower end of the handrail 2 has a connecting rod 21 that bends downward and slides on the column 1. A connecting bag 8 is hung on the connecting rod 21. A water pump 7 is placed inside the connecting bag 8. The water pump 7 is connected to the water inlet 51 of the connecting hose 5.

[0031] like Figure 2 and Figure 3 As shown, the aforementioned clearance hole 31 at one end of the inclined tube 3 near the column 1 is opened on the outer wall of the inclined tube 3. Another clearance hole 31 is the opening at the upper end of the inclined tube 3, through which the connecting hose 5 can pass. 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.

[0032] 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.
