AI Technical Summary
Existing methods for producing sparkling water in water purifiers suffer from high power consumption, complex structure, and high cost. In particular, the Venturi tube structure occupies a large space, making it difficult to widely apply in water purifiers.
The device employs a jet tube assembly, including a jet tube head and a jet tube base. By designing the inner diameter of the jet tube head and the difference in water flow velocity, negative pressure is created, introducing external air to generate bubble water. The structure is simple and can be manufactured at low cost.
It enables low-cost and efficient production of sparkling water in water purifiers, simplifies structural design, and reduces manufacturing costs and space occupation.

Description
Technical Field
[0001] This utility model belongs to the field of water purifier technology, and in particular relates to a device for producing sparkling water in a water purifier. Background Technology
[0002] Sparkling water significantly enhances the user experience in water purifiers. Whether it's the taste of the water when drunk directly, the effectiveness of washing fruits and vegetables, or the shape of the water flow, all are improved.
[0003] The core of making sparkling water is introducing air into the water; therefore, a device for making sparkling water can also be understood as a device that adds air to the water. CN221242534U discloses a water purifier with a sparkling water function, which introduces air into the water through stirring; this method increases the machine's power consumption. Another approach is to use a Venturi tube, i.e., a jet tube, to introduce air. However, due to the complex structure, high manufacturing cost, and large space requirements of existing Venturi tubes, there is no existing technology for using Venturi tubes to make sparkling water in water purifiers. Summary of the Invention
[0004] The purpose of this invention is to provide a device for generating sparkling water in a water purifier using jet technology.
[0005] The technical solution adopted by this utility model is as follows: a device for producing sparkling water in a water purifier, including a jet tube, characterized in that: the jet tube is composed of only a jet tube base and a jet tube head; the jet tube base includes a front part, a middle part, a rear part, and a tail end, integrally formed; the front part has an internal thread, and the rear part and the tail end have hollow cavities, wherein the inner diameter of the rear cavity is consistent, and the inner diameter of the tail end cavity gradually increases from front to back; the front part and the rear part are connected by the middle part, and the tube wall of the middle part has a through hole; the jet tube head is generally frustum-shaped, has an external thread and a hollow cavity, and is connected and fixed to the jet tube base by a threaded fit, wherein the inner diameter of its cavity gradually decreases from front to back, wherein the inner diameter of the front end of the jet tube head is greater than the maximum value of the inner diameter of the tail end of the jet tube base, and the inner diameter of the rear end of the jet tube head is less than the minimum value of the inner diameter of the tail end of the jet tube base.
[0006] The rear end of the jet tube head extends axially beyond the through hole in the middle of the jet tube base, and is clearance-fitted with the rear part of the jet tube base.
[0007] There is an annular sealing ring on the outer wall of the front and rear parts of the jet tube base.
[0008] Furthermore, it also includes a pipeline, in which the jet pipe is installed. The inlet end of the pipeline corresponds to the entire jet pipe head and jet pipe base, and the outlet end of the pipeline corresponds to the tail end of the jet pipe base. The side wall of the pipeline has an air vent, which corresponds to the middle part of the jet pipe base.
[0009] The front and rear sections of this invention are defined according to the direction of water flow, with water flowing from front to back in the waterway. Obviously, the water pressure at the front will be greater than that at the rear.
[0010] In operation, water enters the jet nozzle from the inlet of the pipeline. Due to the unique inner diameter design of this invention, the inner diameter of the jet nozzle is drastically reduced, increasing the water flow velocity. Specifically, the water leaves the jet nozzle at high speed and enters the middle and rear of the jet nozzle base. Upon reaching the base, the water flow slows down, creating a significant negative pressure in the middle section of the base according to Bernoulli's equation. Outside air enters the water through the vents on the pipeline sidewall and the through-holes in the middle of the jet nozzle base, thus generating bubbles in the water. In short, after processing with this invention, ordinary pure water becomes sparkling water.
[0011] The advantage of this invention is its simple structure, requiring only two parts, both of which can be manufactured through a simple injection molding process. Therefore, it can be produced at low cost, enabling its large-scale application in water purifiers. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the jet tube in this utility model.
[0013] Figure 2 This is a cross-sectional view of the present invention.
[0014] See attached diagram. Figure 2 The left side is in front, and the right side is behind. Detailed Implementation
[0015] This utility model includes a pipe 5 connected to a water system, wherein 51 is the water inlet end, 52 is the water outlet end, and a vent 53 is located on the side wall of the middle section; a jet pipe is installed inside the pipe, which is composed of a jet pipe head 1 and a jet pipe base 2.
[0016] The jet nozzle 1 is generally frustum-shaped, with the inner diameter of its inner cavity 10 decreasing from front to back, and the front part having an external thread 11. The jet nozzle base 2 includes a front part 21, a middle part 22, a rear part 23, and a tail end 24, all integrally formed. The front part 21 has an internal thread 25, which can mate with the external thread 11 of the jet nozzle to connect and fix the two. The side wall of the middle part 22 has a through hole 26, the position of which corresponds to the vent 53. The rear part 23 has an inner cavity 230, and the tail end 24 has an inner cavity 240. The front and rear parts of the jet nozzle base each have a sealing ring 3, thereby sealing with the pipeline 5.
[0017] As shown in the figure, the rear end of the jet nozzle 1 is clearance-fitted with the rear part 23 of the jet nozzle base, and the inner cavity 10 of the jet nozzle head is also clearance-fitted with the rear inner cavity 230 of the jet nozzle base. The inner diameter of the rear inner cavity 230 of the jet nozzle base remains unchanged, while the inner diameter of the tail end inner cavity 240 of the jet nozzle base expands from front to back. Initially, it is the same as the inner diameter of the rear inner cavity 230 of the jet nozzle base, and after expansion, it flows out of the jet nozzle base and exits from the outlet 52 of the pipeline. The initial inner diameter of the jet nozzle head 1 is greater than the maximum value of the inner diameter of the tail end 24 of the jet nozzle base, and the inner diameter of the rear end of the jet nozzle head 1 is smaller than the inner diameter of the rear part 23 of the jet nozzle base.
