This invention relates to a gardening hose nozzle structure that can be used to disassemble and assemble the sprinkler head with bare hands.
In gardening work, flowers, plants and trees must be watered regularly to prevent the plants from drying due to lack of water. When plants are planted in a wide range or far away from water sources, the water hose is used to pour. However, the water flowing directly from the water hose cannot be watered over a large area, the watering process is slow, and it is easy to damage the plants. Therefore, a sprinkler or a nozzle is installed at the end of the water hose. In order to utilize the characteristics of the water spray nozzle that can spray water over a large area to achieve more efficient irrigation, the conventional water spray nozzle is equipped with a water spray head, and the front end surface of the water spray head is equipped with several water outlets with different water splash shapes. By holding and rotating the water spray head, the effect of spraying water with different water splashes can be achieved.
However, the conventional structure as mentioned above has the following problems in practical application. (1) The water spray head is fixed on the water spray nozzle through screw locking or high-frequency welding. It is difficult or impossible to remove it with bare hands. Therefore, it is difficult for the water spray nozzle to have different spray shapes. (2) Since the sprinkler head is difficult or impossible to remove when the sprinkler head is damaged or malfunctions, the user may directly abandon the whole water spray nozzle, and it is not environmentally friendly.
It is known that the water spray head of the conventional water spray nozzle is difficult to remove with bare hands, and this is the technical problem to be solved by this application.
This invention provides a garden hose nozzle including a hose nozzle body, at least one sprinkler head, and a water stop ring. The hose nozzle body includes a barrel part, one end of the barrel part is formed with a port, the inner wall of the barrel part is provided with a stopping part protruding inward, the stopping part has a first stopping surface close to the port, and two stoppers are protruding from the inside of the stopping part and are spaced apart from each other. An entrance channel is formed between both sides of the two stoppers, and the two stoppers each form a swivel slot in the direction away from the port, the swivel slot has a closed bottom, and the opening of the swivel slot is connected to the entrance channel. The stopper is formed a limiting block protruding from the inner end close to one side of the entrance channel, and the limiting block is provided a first inclined guide surface. A sleeve pipe extends from one end of the sprinkler head, the outer wall of the sleeve pipe is provided with two projecting ribs that are spaced apart from each other, the projecting rib is formed a second inclined guide surface, and the sleeve pipe is provided with a second stopping surface for the water stop ring to abut and limit the axial direction movement of the water stop ring. When the water stop ring is sleeved on the sleeve pipe, the sleeve pipe can be inserted into the barrel part of the hose nozzle body from the port by aligning the projecting rib and the entrance channel. The water stop ring is axially pushed and squeezed by the first stopping surface and the second stopping surface at the same time, and the water stop ring is also radially pressed by the inner side of the stopping part and the outer side of the sleeve pipe. Cooperating with the elasticity of the water stop ring, the sprinkler head will not easily move relative to the hose nozzle body. Then, the sprinkler head is rotated in one direction after insertion, so that the projecting rib can use the mutual guidance of the second inclined guide surface and the first inclined guide surface to smoothly cross the limiting block and then turn into the swivel slot. The water stop ring is supported between the hose nozzle body and the sprinkler head, and the elasticity of the water stop ring can also be used to actively push the sprinkler head to drive the projecting rib outward to snap into the swivel slot. The sprinkler head can pass through the limitation of the projecting rib caused by the stopper and the limiting block, so that it can no longer be arbitrarily separated from the hose nozzle body, thereby eliminating the need for additional tools. The advantage of disassembly and assembly of the sprinkler head on the hose nozzle body can be completed.
With the structure of this application, the following benefits can be obtained. (1) The sprinkler head can be disassembled and assembled with bare hands, so it can be replaced with different water sprays according to actual use needs. The sprinkler head of different shapes or models will be more flexible in use, and there is no need to prepare multiple water spray guns at the same time for a variety of different water spray needs. (2) The sprinkler head can be disassembled and assembled with bare hands, so when the sprinkler head fails or is damaged, it can be easily replaced, which is relatively energy-saving, avoids waste, and is more environmentally friendly.
The following drawings are merely examples for illustrative purposes according to various disclosed embodiments and are not intended to limit the scope of the present disclosure.
First, as shown in
If the user wants to replace another water spray head 200 during use, the user can press the sprinkler head 20 originally installed on the hose nozzle body 10 and then rotate it in the opposite direction, and the sprinkler head 20 can be removed from the hose nozzle body 10. Another water spray head 200 to be replaced and assembled in the above-mentioned way, and
As shown in
As shown in
The elasticity of the water stop ring 30 actively pushes the sprinkler head 20 outward to drive the projecting rib 22 into the swivel slot 15. The water stop ring 30 can also be stuck between the sprinkler head 20 and the hose nozzle body 10 to achieve a force balance and be able to rotate the sprinkler head 20 freely without loosening. The sprinkler head 20 can be further pressed to cause the water stop ring 30 to undergo more radial deformation and then shrink so that the water stop ring 30 elastically assists the sleeve pipe 21 be axially withdrawn from the barrel part 11, which can be beneficial in disassembling and assembling the sprinkler head 20.
The present invention provides a gardening hose nozzle, wherein the other end of the hose nozzle body 10 different from the port 12 is connected to a grip 16, and the grip 16 is used to connect water sources and can be held.
The present invention provides a gardening hose nozzle, wherein a water control switch 17 is provided on the hose nozzle body 10 so that the water control switch 17 can control the opening and closing of the water source.
The present invention provides a gardening hose nozzle, wherein the water control switch 17 is a push type switch.
The present invention provides a gardening hose nozzle, wherein the water stop ring 30 is a rubber ring with a circular cross-section, which has better friction, elasticity, and radial and axial deformation is relatively average and not easily compressed.
The present invention provides a gardening hose nozzle, wherein the sprinkler head 20 is a high-pressure water spray head that can adjust the spray area, as shown in
The present invention provides a gardening hose nozzle, wherein the sprinkler head 200 is a multi-stage fancy water spray head, as shown in
With the above-mentioned structure of this application, the following benefits can be obtained. First, the sprinkler head 20 or 200 can be disassembled and assembled with bare hands, so it can be replaced with different water sprays according to actual use needs. The sprinkler head 20 or 200 of different shapes or models will be more flexible in use, and there is no need to prepare multiple water spray guns at the same time for a variety of different water spray needs. Second, the sprinkler head 20 or 200 can be disassembled and assembled with bare hands, so when the sprinkler head 20 or 200 fails or is damaged, it can be easily replaced, which is relatively energy-saving, avoids waste, and be more environmentally friendly.
