Description

A jet nozzle capable of detecting water flow Technical Field

[0001] This invention belongs to the technical field of ozone water preparation, specifically relating to a jet device capable of detecting water flow. Background Technology

[0002] The conventional principle of ozone water preparation using jet jets is as follows: ozone is mixed with water using the principle of jet negative pressure. Specifically, the jet jet uses high-speed water flow to generate negative pressure inside the jet jet. Under the action of pressure difference, ozone is automatically drawn into the jet jet and violently stirred and mixed with water inside the jet jet, so that the ozone is fully dissolved in the water to produce ozone water.

[0003] Patent document CN216024166U discloses an ozone water generator, including an ejector, an infrared photoelectric sensor, a control circuit board, a high-voltage transformer, and a quartz tube ozone generator. The infrared photoelectric sensor is installed above the water outlet of the ejector. The control circuit board is electrically connected to the infrared photoelectric sensor and the high-voltage transformer. The quartz tube ozone generator is electrically connected to the high-voltage transformer and connected to the air inlet of the ejector. The problem is that the ejector with the above structure cannot detect in real time whether the water flow enters the valve body, which may cause ozone to be injected prematurely or incorrectly into the ejector, resulting in ozone waste. Alternatively, it may cause ozone to be injected into the ejector with a delay, resulting in ozone not being mixed into the water in time, affecting the quality of the ozone water. Furthermore, if the ozone injection speed and the water flow speed cannot be precisely coordinated and controlled, the ozone and water will not mix sufficiently, affecting the quality of the ozone water.

[0004] Therefore, further improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to overcome at least one of the shortcomings of the prior art and to provide a jet injector that can detect water flow in real time, so that ozone can be accurately injected into the water flow chamber and mixed with water, thereby ensuring the quality of ozone water to a certain extent.

[0006] To achieve the above objectives, the technical solution provided by this utility model embodiment is as follows:

[0007] A jet ejector capable of detecting water flow includes a valve body, on which a water transport chamber, an inlet, an outlet, and an ozone inlet are provided. The inlet, outlet, and ozone inlet are all connected to the water transport chamber. The jet ejector also includes a water flow detection device, which is disposed on the valve body for detecting the water flow rate entering the water transport chamber.

[0008] The water flow detection device includes a magnetic core component and a detection component. The magnetic core component is rotatably disposed in the water transport cavity. The detection component is disposed on the valve body and corresponds to the magnetic core component. When the water flows through the water transport cavity, it drives the magnetic core component to rotate. The detection component receives the rotation of the magnetic core component and detects the water flow rate entering the water transport cavity.

[0009] The water flow detection device further includes a first guide cover and a second guide cover. The first guide cover is disposed in the water transport cavity and located in front of the magnetic core component, and the second guide cover is disposed in the water transport cavity and located in rear of the magnetic core component.

[0010] A first connection structure is provided between the first flow guide cover and the magnetic core component. The magnetic core component is rotatably connected to the first flow guide cover through the first connection structure. The first connection structure includes a first connection hole provided on the first flow guide cover and a first connection shaft provided on the magnetic core component. The first connection hole and the first connection shaft are correspondingly provided and rotate in cooperation with each other.

[0011] The first guide cover is provided with a first water passage hole and a first guide vane. The first water passage hole is disposed through the first guide cover in the front-back direction. There are several first water passage holes arranged in a circumferentially spaced manner. The first guide vane is disposed in the first water passage hole at an angle. The water passes through the first water passage hole, passes through the first guide cover, and generates a vortex water flow through the first guide vane.

[0012] A second connection structure is provided between the second flow guide cover and the magnetic core component. The magnetic core component is rotatably connected to the second flow guide cover through the second connection structure. The second connection structure includes a second connection hole provided on the second flow guide cover and a second connection shaft provided on the magnetic core component. The second connection hole and the second connection shaft are correspondingly provided and rotate in cooperation with each other.

[0013] The water flow detection device also includes a limiting component, which is disposed in the second connecting hole. The limiting component has a spherical surface that contacts the end face of the second connecting shaft, so that there is a gap between the second connecting shaft and the bottom surface of the second connecting hole.

[0014] The second guide cover is provided with a second water passage hole, which is disposed through the second guide cover in the front-to-back direction. There are several second water passage holes arranged at circumferential intervals. The water passes through the second water passage hole and then through the second guide cover.

[0015] The water transport chamber includes an inlet chamber, a mixing chamber, an outlet chamber, and an air inlet chamber. The inlet chamber, mixing chamber, and outlet chamber are arranged sequentially in the direction of water flow. The inlet is located at the inlet end of the inlet chamber, the outlet is located at the outlet end of the outlet chamber, and the ozone inlet is located at the air inlet end of the air inlet chamber. The inlet chamber and the air inlet chamber intersect and connect with the mixing chamber. A water jet nozzle is provided between the inlet chamber and the mixing chamber, and a water diffuser is provided between the mixing chamber and the outlet chamber. The water flow detection device is located in the inlet chamber.

[0016] The cross-sectional dimensions of the mixing chamber gradually increase from the direction of water flow, the cross-sectional dimensions of the water jet nozzle gradually decrease from the direction of water flow, and the cross-sectional dimensions of the water diffuser gradually increase from the direction of water flow.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention incorporates a water flow detection device on the ejector, which is located on the valve body. This device can detect in real time whether water is entering the water transport chamber, ensuring that ozone is injected into the water transport chamber and mixed into the water within a precise timeframe. This avoids wasting ozone and guarantees the quality of the ozone water.

[0019] By installing a water flow detection device on the jet injector, the ozone injection rate and the water flow rate can be precisely controlled in tandem, ensuring that the ozone and water are fully mixed, thus further guaranteeing the quality of the ozone water. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0029] Referring to Figures 1-8, the jet ejector capable of detecting water flow includes a valve body 1. The valve body 1 is provided with a water transport chamber, an inlet 11, an outlet 12, and an ozone inlet 13. In this embodiment, the water transport chamber includes an inlet chamber 14, a mixing chamber 15, an outlet chamber 16, and an air inlet chamber 19. The inlet chamber 14, the mixing chamber 15, and the outlet chamber 16 are arranged sequentially in the direction of water flow. The inlet 11 is located at the inlet end of the inlet chamber 14 and connects to the inlet chamber 14. The outlet 12 is located at the outlet end of the outlet chamber 16. The water inlet 14 and the air inlet 19 are connected to the water outlet 16. The ozone inlet 13 is located at the air inlet end of the air inlet 19 and is connected to the air inlet 19. The water inlet 14 and the air inlet 19 intersect and are connected to the mixing chamber 15. A water jet nozzle 17 is provided between the water inlet 14 and the mixing chamber 15 to connect the water inlet 14 and the mixing chamber 15. The water jet nozzle 17 is located near the ozone inlet 13. A water diffuser 18 is provided between the mixing chamber 15 and the water outlet 16 to connect the mixing chamber 15 and the water outlet 16. The system also includes a water flow detection device. 2. The water flow detection device 2 is installed on the valve body 1. Specifically, it includes a magnetic core component 21 and a detection component 22. The magnetic core component 21 is preferably a magnet, which is cross-shaped and rotatable in the water inlet chamber 14. The detection component 22 is preferably a Hall element, which is installed on the outer wall of the valve body 1 and corresponds to the magnetic core component 21. When water enters the water inlet chamber 14, the magnetic core component 21 rotates under the action of water flow and generates a magnetic field. After the detection component 22 senses the magnetic field, it can determine that water has entered the water inlet chamber 14. Through the above technical solution, the water flow detection device 2 can detect in real time whether the water flow has entered the water transport chamber and send a signal to the control terminal of the ozone water equipment. The control terminal of the ozone water equipment controls the ozone to be injected into the mixing chamber 15 within an accurate time, so that the ozone and water can be fully mixed. This avoids wasting ozone by injecting ozone into the mixing chamber 15 in advance and avoids reducing the quality of ozone water by injecting ozone into the mixing chamber 15 in a delayed or incorrect manner. To a certain extent, the quality of ozone water can be guaranteed.

[0030] In addition, by installing a water flow detection device 2 on the jet injector, the control terminal of the ozone water equipment can control the ozone injection speed in a timely manner based on the data provided by the water flow detection device 2, so that the ozone injection speed and the water flow speed can be precisely coordinated and controlled to ensure that the ozone and water are fully mixed, thereby further ensuring the quality of the ozone water.

[0031] Furthermore, the water flow detection device 2 also includes a first guide cover 23. Specifically, in this embodiment, the first guide cover 23 is disposed in the water inlet cavity 14 and located in front of the magnetic core component 21. A first step is provided on the water inlet end of the water inlet cavity 14. The first step is arranged around the inner side wall of the water inlet cavity 14, and the diameter of its inner wall surface is smaller than the diameter of the outer peripheral wall of the first guide cover 23. When the first guide cover 23 abuts against the first step and the outer peripheral wall of the first guide cover 23 is interference-fitted with the inner side wall of the water inlet cavity 14, the first guide cover 23 is installed in the water inlet cavity 14. This is understandable to those skilled in the art.

[0032] The water flow detection device 2 also includes a second guide cover 24. Specifically, in this embodiment, the second guide cover 24 is disposed in the water inlet cavity 14 and located behind the magnetic core component 21. A second step is provided on the water outlet end of the water inlet cavity 14. The second step is arranged around the inner side wall of the water inlet cavity 14, and the diameter of its inner wall surface is smaller than the diameter of the outer peripheral wall of the second guide cover 24. When the second guide cover 24 abuts against the second step and the outer peripheral wall of the second guide cover 24 is interference-fitted with the inner side wall of the water inlet cavity 14, the second guide cover 24 is installed in the water inlet cavity 14. This is understood by those skilled in the art.

[0033] Furthermore, a first connecting structure is provided between the first flow guide cover 23 and the magnetic core component 21. Specifically, in this embodiment, the first connecting structure includes a first connecting hole 231 and a first connecting shaft 211. The first connecting hole 231 is disposed on the first flow guide cover 23 and located in the middle of the end face facing the magnetic core component 21. The first connecting shaft 211 is disposed on the magnetic core component 21 and located in the middle of the end face facing the first flow guide cover 23. The first connecting hole 231 and the first connecting shaft 211 are correspondingly disposed. When the first connecting shaft 211 is inserted into the first connecting hole 231 and the two rotate and cooperate with each other, the magnetic core component 21 is rotatably mounted on the first flow guide cover 23. Through the above technical solution, the magnetic core component 21 can be positioned and rotatably mounted in the middle of the water inlet cavity 14, avoiding contact between the magnetic core component 21 and the inner wall surface of the water inlet cavity 14, thus extending the service life of the magnetic core component 21. This is understandable to those skilled in the art.

[0034] Furthermore, the first guide cover 23 is provided with a first water passage hole 232 and a first guide vane 233. Specifically, in this embodiment, the first water passage hole 232 is disposed through the first guide cover 23 in the front-back direction, and the number of the first water passage hole 232 is preferably five and arranged circumferentially at intervals on the end face of the first guide cover 23. The number of the first guide vane 233 is preferably five and is respectively inclinedly disposed on the wall surface of the five first water passage holes 232. When water passes through the first water passage hole 232 and passes through the first guide cover 23, it generates a vortex flow in the water inlet cavity 14 through the guiding action of the first guide vane 233. Through the above technical solution, the water forms a swirling flow when passing through the water inlet cavity 14, so as to drive the magnetic core component 21 to rotate. This is understood by those skilled in the art.

[0035] Furthermore, a second connecting structure is provided between the second flow guide cover 24 and the magnetic core component 21. Specifically, in this embodiment, the second connecting structure includes a second connecting hole 241 and a second connecting shaft 212. The second connecting hole 241 is disposed on the second flow guide cover 24 and located in the middle of the end face facing the magnetic core component 21. The second connecting shaft 212 is disposed on the magnetic core component 21 and located in the middle of the end face facing the second flow guide cover 24. When the second connecting shaft 212 is inserted into the second connecting hole 241 and the two rotate in cooperation with each other, the magnetic core component 21 is rotatably mounted on the second flow guide cover 24. Through the above technical solution, under the positioning action of the first flow guide cover 23 and the second flow guide cover 24, the magnetic core component 21 is more stable when rotating, which further extends the service life of the magnetic core component 21. This is understandable to those skilled in the art.

[0036] Furthermore, the water flow detection device 2 also includes a limiting component 25. Specifically, in this embodiment, the limiting component 25 has a spherical surface and is disposed within the second connecting hole 241 and in contact with the end face of the second connecting shaft 212. When the second connecting shaft 212 extends into the second connecting hole 241, there is a gap between the end of the second connecting shaft 212 and the bottom surface of the second connecting hole 241. Through the above technical solution, the spherical limiting component 25 can prevent the end of the second connecting shaft 212 from directly contacting the bottom surface of the second connecting hole 241, reducing the rotational resistance of the magnetic core component 21 and reducing the rotational loss of the end of the second connecting shaft 212. This can extend the service life of the magnetic core component 21 to a certain extent, as can be understood by those skilled in the art.

[0037] Furthermore, the second guide cover 24 is provided with a second water passage hole 242. Specifically, in this embodiment, the second water passage hole 242 is disposed through the second guide cover 24 in the front-back direction. The number of the second water passage hole 242 is preferably three and arranged circumferentially at intervals on the end face of the second guide cover 24. Water passes through the second guide cover 24 through the second water passage hole 242. Through the above technical solution, water flows through the second guide cover 24 and flows to the mixing chamber 15. This is understood by those skilled in the art.

[0038] Furthermore, in this embodiment, the cross-sectional dimensions of the mixing chamber 15 gradually increase from the direction of water flow. Specifically, the water generates turbulence and vibration in the mixing chamber 15, so that the ozone and water in the mixing chamber 15 can be fully mixed under vibration, ensuring the production quality of ozone water. This is understood by those skilled in the art.

[0039] In this embodiment, the cross-sectional size of the water jet nozzle 17 gradually decreases from the direction of water flow. Specifically, this increases the pressure when water enters the mixing chamber 15, creating a negative pressure between the ozone inlet 13 and the mixing chamber 15 and drawing ozone into the mixing chamber 15, so that ozone can enter the mixing chamber 15 and mix with water. This is something that those skilled in the art can understand.

[0040] In this embodiment, the cross-sectional size of the water flow diffuser 18 gradually increases from the direction of water flow. Specifically, this reduces the flow velocity of water entering the outlet chamber 16, allowing the ozone water in the outlet chamber 16 to be smoothly output to the outside of the jet injector through the outlet 12. This is something that those skilled in the art can understand.

[0041] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
