Description

Technical Field

[0001] The utility model relates to a leakage-proof water mist spray nozzle, and relates to the technical field of spray nozzle equipment. Background Art

[0002] Watering cans are often used to water flowers and sprinkle water in people's daily lives, and the water flow can be adjusted into a water column or water mist by rotating the front end of the nozzle to adjust the nozzle.

[0003] The front end of an existing nozzle is usually a water diverter valve sleeve installed in the nozzle, and the front end of the water diverter valve is connected to the nozzle to discharge water. However, due to the lack of a sealing structure, water leakage may occur at the connection end between the water diverter valve and the nozzle during the water spraying process, especially when adjusting. If the rotation is not in place, the leakage is particularly obvious, affecting the normal use experience. Therefore, a leak-proof nozzle structure is proposed to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of the utility model is to provide a leakage-proof water mist nozzle in response to the defects or shortcomings in the prior art.

DETAILED DESCRIPTION

[0025] See also Figure 1-7 As shown, the technical solution adopted in this specific embodiment is: it includes a nozzle body 1 and a nozzle 2, the nozzle 2 is movably arranged at the front end of the nozzle body 1 through a threaded groove 2-2, a flow channel 1-1 is arranged in the nozzle body 1, a connecting nozzle 3 is arranged at the front end outlet of the flow channel 1-1, the connecting nozzle 3 extends into the nozzle 2, a sealing leather cup 3-1 is arranged on the outer side of the middle part of the connecting nozzle 3 and connected to the bottom of the nozzle 2, a connecting nozzle plug-in groove 1-2 is arranged on the outer side of the front end of the flow channel 1-1, and the connecting nozzle plug-in groove 1-2 matches the connecting nozzle 3. In the traditional nozzle structure, the nozzle is easily connected to the nozzle water distributor. In order to prevent water leakage and the rotating part from leaking, a connecting nozzle plug-in groove is provided on the outside of the front end of the flow channel in the nozzle in this embodiment, and a connecting nozzle is provided in the connecting nozzle plug-in groove, which is connected to the nozzle through the connecting nozzle. Therefore, when spraying water or stopping water, water will not flow back from the connection and leak out, thus performing the first layer of waterproofing. At the same time, a sealing leather cup is provided on the outside of the connecting nozzle to contact with the bottom of the nozzle for adsorption sealing, thus performing the second layer of sealing. When there is a problem with the internal sealing structure and water leaks, it can also be sealed from the outside, so that rapid and large-scale water leakage will not occur, which is convenient for users to find problems in time and deal with them.

[0026] To be more specific, the connecting nozzle 3 is a structure with a wide lower section and a narrow upper section, and the transition between the upper and lower sections is an inclined water inlet 3-2 with a narrow upper section and a wide lower section. By setting the connecting nozzle to a structure with a small upper section and a large lower section, and providing an inclined water inlet, the water flow can be accelerated when passing through.

[0027] To be more specific, the connecting nozzle 3 is provided with a partition leather ring 6 near the bottom water inlet end, and a water hole 6-1 is provided in the center of the partition leather ring 6. When the water spraying ends, the water flow will stop or flow back slightly under the action of pressure, and a small amount of water remaining at the connecting end of the nozzle will leak. By providing an elastic partition leather ring, a rebound will occur when the water flow stops or retreats through the water hole, driving the water flow to retreat, reducing the storage amount of water in the nozzle, and thereby reducing the occurrence of water leakage.

[0028] More specifically, a connecting nozzle mounting groove 2 - 1 is provided at the center of the nozzle 2 , and a limiting opening 2 - 3 of an opening structure is provided at the bottom of the connecting nozzle mounting groove 2 - 1 , and the limiting opening 2 - 3 matches the water inlet 3 - 2 of the connecting nozzle 3 .

[0029] More specifically, a water dividing plate 4 is provided on the top of the connection nozzle installation groove 2-1.

[0030] More specifically, a sealing groove 2-4 is provided at the top of the connecting nozzle installation groove 2-1 near the bottom inner wall of the water dividing plate 4, and a sealing ring 5 is provided at the top of the connecting nozzle 3, and the sealing ring 5 matches the sealing groove 2-4. By providing a sealing ring at the top of the connecting nozzle to match the connecting nozzle installation groove for a sealed connection, it can be sealed when the nozzle housing drives the water dividing plate to rotate and adjust, thereby preventing moisture from leaking from the outside of the connecting nozzle.

[0031] More specifically, the inner side of the top of the connecting nozzle 3 is inclined inward to form an inclined surface, and the setting of the inclined surface is conducive to the water flowing out and flowing from the main cavity when the water retreats, instead of flowing out from the outer wall.

[0032] The working principle of the utility model: during installation, the connecting nozzle 3 is inserted into the connecting nozzle plug-in groove 1-2 outside the flow channel 1-1, and the water flow of the flow channel 1-1 directly enters the connecting nozzle 3 without leakage. After the connecting nozzle 3 is installed in the connecting nozzle installation groove 2-1, the sealing ring 5 is embedded in the sealing groove 2-4 to prevent water leakage at the connection part between the connecting nozzle 3 and the water distribution plate 4. At the same time, the sealing leather cup 3-1 is connected to the bottom of the nozzle 2, so that there is a little adsorption force between the sealing leather cup 3-1 and the nozzle 2, which can prevent water leakage from the outside when the inner wall sealing structure fails, and is also convenient for inspection and maintenance. The triple anti-leakage structure can greatly improve the sealing performance of the nozzle and enhance the user experience.

[0033] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
