Description

Technical Field

[0001] This invention relates to the field of umbrella technology, and in particular to a safety automatic opening and closing umbrella. Background Technology

[0002] Umbrellas are everyday items used for sun and rain protection. The most common types include rain umbrellas, parasols, oil-paper umbrellas, and beach umbrellas. Structurally, they generally consist of a main pole, ribs, canopy, and handle. The main pole can be single-sectioned or multi-sectioned. In early umbrellas, the user had to hold the handle with one hand and reach into the ribs with the other to push the connecting rod upwards, causing the canopy to open with the ribs. To close the umbrella, the connecting rod was pulled down. Because these types of umbrellas required both hands to open and close, they were inconvenient to use if the user had items in one hand or was injured and unable to use the umbrella. Therefore, technology was developed that allowed for automatic opening and closing of umbrellas with one hand.

[0003] While automatic opening and closing umbrellas can meet the needs, when the umbrella is closed, water droplets still remain on it and drip onto the floor, wetting it. This not only increases the risk of slipping for others but also makes the floor messy and inconvenient for users. To address these problems, this invention was developed. Summary of the Invention

[0004] Therefore, in view of the above problems, the present invention proposes a safe automatic opening and closing umbrella with a simple structure that can collect dripping water and prevent the floor from getting wet.

[0005] To solve the above-mentioned technical problems, the solution adopted by the present invention is as follows: a safe automatic opening and closing umbrella, including an umbrella body, an umbrella handle provided on the umbrella body, and an umbrella handle sleeve. The umbrella handle sleeve has a drainage channel for the umbrella body to pass through. The bottom of the umbrella handle sleeve has a water collection trough for collecting water. The water collection trough is connected to the drainage channel. The umbrella handle sleeve has a closing device at the port of the water collection trough for closing the water collection trough after it is full of water.

[0006] A further improvement is that the closing device includes two symmetrically arranged closing plates, which slide through the umbrella handle sleeve and are located at the channel of the water collection tank. The closing plates resist each other and seal within the channel of the water collection tank. The umbrella handle sleeve is provided with a sliding device for automatically driving the sealing plate to slide after the water collection tank is full of water.

[0007] A further improvement is that the sliding device includes a screw, the sealing plate is a square plate, the screw passes through the sealing plate and is threadedly driven by the sealing plate, the umbrella handle sleeve is provided with a rotating motor for driving the screw to rotate, and the umbrella handle sleeve is provided with a control device for driving the rotating motor to rotate after the water collection tank is full.

[0008] A further improvement is that the control device includes a first conductive block and a second conductive block, and the umbrella handle sleeve is provided with a control module electrically connected to the rotating motor. The umbrella handle sleeve has a first guide groove and a second guide groove connected to the water collection tank at its upper end. The first conductive block is electrically connected to the power supply device, and the second conductive block is electrically connected to the control module.

[0009] A further improvement is that the umbrella handle is equipped with a drying device from top to bottom for drying the umbrella.

[0010] A further improvement is that the drying device includes a drying heating tube, which is arranged from top to bottom, and the umbrella handle sleeve is also provided with a heat insulation layer to prevent heat loss.

[0011] A further improvement is that the umbrella handle is also equipped with a drainage device to drain the water from the collection trough.

[0012] A further improvement is that the drainage device is a sealing plug, and the bottom of the umbrella handle sleeve has a drainage channel that communicates with the water collection tank. The sealing plug is threaded through the drainage channel to seal the drainage channel.

[0013] A further improvement is that it also includes a connecting block, which is located on the umbrella ribs of the umbrella body. The connecting block is threadedly connected to the umbrella ribs to seal the umbrella body within the drainage channel.

[0014] By adopting the aforementioned technical solution, the beneficial effects of the present invention are: With a simple structure, it collects dripping water, preventing the floor from getting wet. In use, after closing the umbrella, insert it into the handle sleeve, allowing water to drain downwards into the collection tank, preventing water from dripping directly onto the floor and causing it to become wet, thus preventing a mess and slippery conditions. When the collection tank is full, the water submerges the first and second conductive blocks, energizing the control module. The control module then controls a rotating motor, which in turn rotates a screw. The screw, through threaded contact with a sealing plate, slides the sealing plate into the channel of the collection tank. The two sealing plates seal each other, separating the water from the umbrella and preventing water from flowing back onto the umbrella when the handle sleeve shakes. This prevents the umbrella from rusting due to prolonged immersion in water, extending its lifespan. Attached Figure Description

[0016] Figure 2 This is a schematic diagram of the structure of Embodiment A of the present invention. Detailed Implementation

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to Figure 1-2 The present invention discloses a safety automatic opening and closing umbrella, comprising an umbrella body 1, an umbrella handle 2 disposed on the umbrella body 1, and an umbrella handle sleeve 3. The umbrella handle sleeve 3 has a drainage channel through which the umbrella body 1 passes. The bottom of the umbrella handle sleeve 3 has a water collection trough 5 for collecting water, and the water collection trough 5 is connected to the drainage channel. The umbrella handle sleeve 3 has a closing device at the port of the water collection trough 5 for closing the water collection trough 5 after it is full of water. The closing device includes two symmetrically arranged sealing plates 9, which slide through the umbrella handle sleeve 1. The umbrella handle sleeve 3 is located on the channel of the water collection tank 5. The sealing plates 9 resist each other and seal within the channel of the water collection tank 5. The umbrella handle sleeve 3 is provided with a screw 10 for automatically driving the sealing plate 9 to slide after the water collection tank 5 is full of water. The sealing plate 9 is a square plate. The screw 10 passes through the sealing plate 9 and is threadedly driven by the sealing plate 9. The umbrella handle sleeve 3 is provided with a rotary motor 11 for driving the screw 10 to rotate. The umbrella handle sleeve 3 is provided with a control device for driving the rotary motor 11 to rotate after the water collection tank 5 is full of water.

[0019] Specifically, the control device includes a first conductive block 7 and a second conductive block 8. The umbrella handle sleeve 3 houses a control module electrically connected to the rotating motor 11. The umbrella handle sleeve 3 has a first guide groove and a second guide groove connected to the water collection tank 5 at its upper end. The first conductive block is electrically connected to a power supply device, and the second conductive block 8 is electrically connected to the control module. In use, after closing the umbrella, it is inserted into the umbrella handle sleeve 3, allowing water on the umbrella to drain downwards into the water collection tank 5, preventing water from dripping directly onto the floor and causing it to become wet, thus preventing the floor from becoming dirty and causing others to slip. When the water in the water collection tank 5 is full, the water submerges the first conductive block 7 and the second conductive block 8, thereby energizing the control module. The control module then controls the rotating motor 11 to rotate, which in turn drives the screw 10 to rotate. The screw 10 is threadedly driven by the sealing plate 9, which in turn drives the sealing plate 9 to slide into the channel of the water collection tank 5. The two sealing plates 9 seal each other, thereby sealing the water collection tank 5 and separating the water in the water collection tank 5 from the umbrella. This prevents water from flowing back onto the umbrella when the umbrella handle sleeve 3 shakes, which would otherwise cause the umbrella to rust easily due to long-term immersion in water.

[0020] In order to dry the umbrella and store it better, a drying heating tube 12 is also included. The drying heating tube 12 is arranged from top to bottom, and the umbrella handle sleeve 3 is also provided with a heat insulation layer to prevent heat loss.

[0021] In order to drain the water in the water collection tank 5, a sealing plug 6 is provided on the umbrella handle 2 to drain the water in the collection tank. The bottom of the umbrella handle sleeve 3 is provided with a drainage channel that is connected to the water collection tank 5. The sealing plug 6 is threaded through the drainage channel to seal the drainage channel.

[0022] To further prevent rainwater leakage and accidental activation of the automatic switch while using the umbrella, a connecting block 4 is included. The connecting block 4 is located on the umbrella ribs of the umbrella body 1 and is threadedly connected to the ribs, sealing the umbrella body 1 within the drainage channel. During drainage, the threaded connection between the umbrella handle sleeve 3 and the connecting block 4 further prevents internal rainwater from flowing out, facilitating proper drying. When the umbrella is in use, the umbrella handle sleeve 3 can be threaded in the opposite direction onto the connecting block 4, thus sealing the umbrella handle 2 and preventing accidental activation of the button while using the umbrella. This prevents the umbrella from closing during use or opening automatically, improving the safety of umbrella use.
