Description

Technical Field

[0001] This utility model relates to the field of tea utensil technology, and more specifically, to a simple tea brewing strainer. Background Technology

[0002] A utility model patent with patent application number CN202023037498.9 discloses a tea brewing strainer. The filter in this tea strainer is supported by multiple support protrusions arranged circumferentially on the inner wall of the strainer cup. In actual use, this support method is prone to damage to the support protrusions due to aging or collision, causing the filter to fail to support the filter. It is also inconvenient to clean. Furthermore, the diameter of the first vent hole below the gas collection hood is too large, allowing too much boiling water to enter the spray pipe through the first vent hole and then spray out too much steam from the steam nozzles on the spray pipe. In addition, during the tea brewing process, tea leaves and tea residue can also easily enter the spray pipe through the first vent hole, causing the steam nozzles to be blocked. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a simple tea brewing strainer to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a simple tea brewing strainer, including a strainer cup, the lower surface of which has several permeable slits extending circumferentially, the inner wall of which has a concave annular protrusion extending circumferentially, a support cover placed on the annular protrusion, a filter plate placed on the support cover, several permeable holes extending through the filter plate, an insertion hole coaxially extending through the support cover and the filter plate, a guide tube inserted into the insertion hole, a horn cover at the bottom end of the guide tube, the bottom end face of the strainer cup being concave arc-shaped, several first through holes corresponding to the horn cover extending through the bottom end face of the strainer cup, the horn cover covering all the first through holes, the top end of the guide tube being sealed, several air vents extending circumferentially extending through the surface of the guide tube above the filter plate, and several second through holes extending circumferentially extending through the inner wall of the strainer cup below the annular protrusion.

[0005] As a preferred embodiment of this invention, the water-permeable holes on the filter are processed by laser drilling.

[0006] As a preferred embodiment of this utility model, the depth of the annular protrusion extending into the infuser cup is controlled to be 1.5-2 mm.

[0007] As a preferred technical solution of this utility model, the diameter of the permeable hole is controlled between 0.2 and 0.3 mm.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] By setting a ring-shaped protrusion on the inner wall of the infuser cup, the support cover and filter are supported by the ring-shaped protrusion, which is not only more secure, but also easier to clean. At the same time, the first through hole below the horn cover is set to multiple, which can reduce the amount of water sprayed from the air outlet on the guide tube, prevent boiling water from splashing everywhere, and improve the steam spraying effect. In addition, the first vent hole in the existing technology is replaced with several first through holes, which can prevent tea leaves and tea residue from entering during the tea brewing process.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 3As shown, this utility model provides a simple tea brewing infuser, including a tea infuser cup 1. The lower surface of the tea infuser cup 1 has several permeable slits 2 extending circumferentially. The inner wall of the middle part of the tea infuser cup 1 has a concave annular protrusion 3 extending circumferentially. A support cover 4 is placed on the annular protrusion 3 in the tea infuser cup 1. A filter sheet 5 is placed on the support cover 4. Several permeable holes 6 are extending through the filter sheet 5. An insertion hole is coaxially extending through the support cover 4 and the filter sheet 5. A guide tube 7 is inserted into the insertion hole. A horn cover 8 is provided at the bottom end of the guide tube 7. The bottom end surface of the tea infuser cup 1 is concave arc-shaped. Several first through holes 9 corresponding to the horn cover 8 are extending through the bottom end surface of the tea infuser cup 1. The horn cover 8 covers all the first through holes 9. The top end of the guide tube 7 is sealed. Several air vents 10 are extending circumferentially through the surface of the guide tube 7 above the filter sheet 5. Several second through holes 11 are extending circumferentially through the inner wall of the tea infuser cup 1 below the annular protrusion 3. The depth of the annular protrusion 3 extending into the infuser cup 1 is controlled at 1.5-2 mm. The diameter of the water-permeable hole 6 is controlled at 0.2-0.3 mm. By using the annular protrusion 3 to support the support cover 4 and the filter plate 5, compared with the existing technology that uses multiple individual support protrusions, it is more robust and will not fall off due to collision during cleaning, thus preventing subsequent support failure. Moreover, the annular protrusion 3 has a smooth surface without dead corners, making it easier to clean with cleaning tools. At the same time, the filter plate 5 and the support cover 4 are designed to be separable, making it easier and faster to replace the filter plate 5. Furthermore, the first through hole 9 is set to multiple, which weakens the water splashes entering the funnel cover 8 during the boiling process, preventing excessive boiling water splashes from entering the conduit 7 and causing excessive water to spray out of the steam outlet 10 on the conduit 7. This allows the steam outlet 10 to spray steam more effectively, and also prevents tea leaves and tea residue from entering the conduit 7 during the tea brewing process.

[0016] The permeable holes 6 on filter sheet 5 are processed using laser drilling. Laser perforation and slag removal technology is a method of processing materials using a laser beam. Its principle is to utilize the high energy and high density of the laser to instantly heat and vaporize the material under the action of the laser beam, thereby forming holes. Simultaneously, the laser beam also evaporates or melts the material around the holes, creating a molten zone at the edge of the holes. This effectively removes residue around the holes, achieving a one-time perforation and slag removal process. To avoid burrs around the permeable holes 6 that could cause tea leaves to easily stick to them and make cleaning inconvenient, laser drilling is used. The molten zone generated by the laser processing reduces residue at the edges of the permeable holes 6, making cleaning the entire filter sheet 5 much easier.

[0017] In use, this utility model has a ring-shaped protrusion 3 on the inner wall of the infuser cup 1, which supports the cover 4 and filter 5. This not only makes it more secure but also makes it easier to clean. At the same time, the first through hole 9 below the horn cover 8 is set to be multiple, which can reduce the amount of water sprayed out of the air outlet 10 on the guide tube 7, prevent boiling water from splashing everywhere, and improve the steam spraying effect.
