Description

Technical Field

[0001] This utility model belongs to the field of water-saving irrigation technology, and more specifically, it relates to a high-precision filter patch dripper and drip irrigation tape. Background Technology

[0002] Existing patch-type drippers mainly consist of an inlet, a turbulent flow channel, an outlet window, and a filter slot. The inlet, as the first filtration structure, significantly impacts the dripper's anti-clogging performance. Currently, most patch-type drippers on the market are manufactured using injection molding. The inlet features a filter window structure, the size of which is primarily limited by the punch used to form it within the mold. Theoretically, a smaller punch size results in a smaller filter window and better filtration at the inlet. However, in practical applications, due to limitations in the punch's material strength, a small punch is prone to damage during mold closing collisions, leading to punch breakage and affecting mold life. Utility Model Content

[0003] The purpose of this invention is to provide a high-precision filter patch dripper and drip tape, which aims to solve the problem that the size of the filter window structure in the existing patch dripper is too small, which can easily lead to mold damage.

[0027] Please see Figure 1 This invention provides a high-precision filter patch dripper. The high-precision filter patch dripper includes a dripper body 1, with a water inlet groove 11 on the front side and a filter screen 2 covering the water inlet groove 11. A water outlet groove is located on the back side of the dripper body 1, and a filter window structure 12 connecting the water inlet groove 11 and the water outlet groove is provided within the water inlet groove 11.

[0028] The present invention provides a high-precision filter patch dripper. Compared with the prior art, by setting a filter screen 2 on the water inlet tank 11, the filter screen 2 filters the water and undertakes the filtering function of the filter window structure 12. This allows the filter window structure 12 to be appropriately increased in size, thereby avoiding the problem of mold damage caused by the filter window structure 12 being too small.

[0029] In actual production, the existing 0.5mm inlet filter window structure (12-inch inner circle diameter) is equivalent to a 35-mesh filtration precision. However, under normal operating conditions, drip irrigation tape generally requires water to undergo filtration with a precision of 35 mesh or higher. Therefore, in drip irrigation tape application scenarios, a primary filtration system must also be installed for water filtration, increasing costs.

[0030] In some embodiments, the filter screen 2 is a woven mesh made of thermoplastic plastic material, such as polyethylene resin as the raw material. The polyethylene resin is sprayed out under high pressure through a nozzle in a viscous flow state by a spinneret and then cooled and shaped to obtain polyethylene filaments. The polyethylene filaments are then woven by a braiding machine to obtain the filter screen 2. In this embodiment, the filtration accuracy of the filter screen 2 is greater than 35 mesh. In this way, the drip irrigation tape using the dripper provided by this utility model can eliminate the need for the head-mounted filtration system during use, thereby reducing production costs.

[0031] Preferably, the mesh size of filter 2 is between 60 and 80 mesh.

[0032] In some embodiments, please refer to Figure 2 A process groove 3 is provided on the front side of the dripper body 1. The process groove 3 penetrates the front side of the dripper body 1 and is located on one side of the water inlet groove 11. In this embodiment, the process groove 3 and the water inlet groove 11 are not connected to each other. There can be one or more process grooves 3. In some embodiments, the process groove 3 is set on one edge of the front side of the dripper body 1. This makes the process groove 3 form a stepped structure on the front side of the dripper body 1, which facilitates the demolding of the dripper body 1 during injection molding.

[0033] In some embodiments, please refer to Figure 3 The process tank 3 includes a first tank body 31 and a second tank body 32. The first tank body 31 is located on one or both sides of the width direction of the water inlet tank 11, and the second tank body 32 is located on one or both sides of the length direction of the water inlet tank 11.

[0034] In actual production, please refer to Figure 4The filter screen 2 is obtained by cutting a large mesh 20. The combination of the dripper body 1 and the filter screen 2 is achieved through the following steps: First, multiple dripper bodies 1 are arranged in an array with their front faces facing up. Then, the mesh 20 is placed over the array structure formed by the multiple dripper bodies 1. The bonding area between the mesh 20 and the dripper body 1 is locally and rapidly heated by an ion heating nozzle to form a molten layer. Then, the mesh 20 is pressed onto the dripper body by a pressure roller to bond and fix the dripper body and the mesh 20. Then, the mesh 20 is cut into small pieces of filter screen 2 attached to the dripper body by a circular cutting blade 4 along the process groove 3 on the dripper body. Finally, the multiple dripper bodies are separated to obtain the dripper body with the filter screen 2 attached.

[0035] This utility model also provides a drip irrigation tape that uses the aforementioned high-precision filter patch dripper.

[0036] The drip irrigation tape provided by this utility model uses the aforementioned high-precision filter patch dripper, which, compared with the prior art, possesses all the beneficial effects of the aforementioned high-precision filter patch dripper, improves the filtration effect of the drip irrigation tape, eliminates the need for a filtration system installed at the head of the drip irrigation tape, and reduces production costs.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
