Description

Technical Field

[0001] The utility model belongs to the technical field of atomizing spray heads, and in particular relates to an atomizing spray head. Background Art

[0002] The atomizing sprinkler head is a device that atomizes the liquid and sprays it evenly into the surrounding environment. Because of its small size, convenience, uniform spraying and good atomization effect, it is widely used in agricultural irrigation, garden maintenance, beam field maintenance and other fields.

[0003] The existing water pipe is connected to the atomizing spray head through a connecting head, and before the water in the water pipe enters the atomizing spray head, the impurity particles in the water will be filtered through the filter in the connecting head to avoid clogging the spray hole of the atomizing spray head. When the liquid enters the nozzle, the liquid is subdivided into tiny particles through shearing and collision in the nozzle, thereby increasing the surface area of ​​the liquid, so that the liquid can be evenly sprayed or atomized to achieve the expected spray effect. However, when the impurity particles in the water are filtered through the filter, the filtered impurity particles will adhere to the surface of the filter and gradually accumulate, thereby causing the filter to be blocked, slowing down the water flow speed entering the atomizing spray head, thereby affecting the spraying effect of the atomizing spray head. Therefore, it is necessary to disassemble the atomizing spray head to clean the blocked filter, and then reinstall the atomizing spray head after cleaning. Therefore, when cleaning the atomizing spray head, it is necessary to stop the machine to disassemble and clean the atomizing spray head, which makes the cleaning operation of the atomizing spray head more troublesome.

[0008] Preferably, the dredging assembly includes guide rods and circular plates. The guide rods are provided in two groups and one end of the two groups of guide rods is connected to the sleeve. A fixing plate is provided between the two groups of guide rods, and both ends of the fixing plate are slidably sleeved on the surface of the guide rods.

[0009] Preferably, the middle portion of the fixing plate is connected to the circular plate via a fixing rod, and the ejector pins are provided in a plurality of groups and are evenly distributed on the surface of the circular plate.

[0010] Preferably, a spring is sleeved on the surface of the guide rod, and two ends of the spring are respectively connected to the sleeve and the fixing plate.

[0011] Preferably, the threaded member includes a mounting tube and a second external thread on the surface of the mounting tube, and the mounting tube is connected to one end of the spray head.

[0012] Preferably, an internal thread is provided in one end of the sleeve away from the connecting pipe, the second external thread is threadedly connected to the internal thread, and the nozzle is threadedly connected to the sleeve, so that the nozzle can be easily disassembled and assembled.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The first external thread on the surface of the connecting pipe is threadedly fixed to the external water pipe, so that the water in the water pipe can enter the connecting pipe. When entering the connecting pipe and flowing into the sleeve, the impurities and particulate matter in the water will be filtered through the filter, so that the filtered water can flow to the nozzle and be sprayed out from the nozzle, thereby avoiding the problem of impurities and particulate matter in the water clogging the nozzle.

[0016] After the impurities and particulate matter in the water are filtered through the filter, when the impurities and particulate matter clog the filter, the water flow flowing into the connecting pipe is adjusted. When the adjusted water flow rate is small, the spring rebounds and drives the fixed plate to move toward the end close to the filter, and while the fixed plate moves, the circular plate is driven toward the filter through the fixed rod. When several ejectors on the surface of the circular plate contact and insert into the mesh of the filter, the impurities and particulate matter clogged in the mesh of the filter are ejected by the ejectors, thereby unblocking the mesh of the filter, avoiding the problem of impurities and particulate matter clogged in the mesh. By adjusting the size of the water flow, the impurities and particulate matter clogged in the mesh can be unblocked, and the operation is relatively convenient, avoiding the problem of disassembling the nozzle for cleaning and unblocking when blocked.

A filter screen 5 for filtering water entering the sleeve 1 is detachably connected in the connecting pipe 2. A dredging component 6 for clearing particles clogged on the surface of the filter screen 5 is provided in the sleeve 1. The ejector pin 7 of the dredging component 6 is inserted into the mesh 8 of the filter screen 5 so that the ejector pin 7 can push out the particles clogged in the mesh 8, thereby clearing the clogged mesh 8.

[0026] The dredging assembly 6 includes a guide rod 9 and a circular plate 10. The guide rod 9 is provided in two groups and one end of the two groups of guide rods 9 is connected to the sleeve 1. A fixing plate 11 is provided between the two groups of guide rods 9. Both ends of the fixing plate 11 are slidably sleeved on the surface of the guide rod 9.

[0027] The middle part of the fixed plate 11 is connected to the circular plate 10 through a fixed rod 17. The ejector pins 7 are provided in a plurality of groups and are evenly distributed on the surface of the circular plate 10. The ejector pins 7 can be inserted into the mesh 8 of the filter screen 5, so that the impurities and particulate matter blocked in the mesh 8 of the filter screen 5 can be ejected by the ejector pins 7.
