The ejection direction of each of the first fluid pressurization components (1) converges at the same focus (301) which is located in the convergence cavity (3). The included angle between the ejection direction of the first fluid pressurization component (1) and the central axis (5) is greater than 0° and less than 90°. Since the ejection direction of each first fluid pressurization component converges at the same focus, when used as a shower head, the first fluid pressurization components eject high-pressure fluids which collide at the focal point to form high-speed droplets that resemble an explosion pulse.

Background technique

With the development of modern cities, the height of urban buildings is getting higher and higher, and there is a problem of low tap water pressure in high-rise buildings. In addition, rural and remote towns also have the problem of low water pressure due to long water pipelines.

In addition, ordinary shower heads cannot atomize water droplets, resulting in a large amount of water wasted in bathing, and low water pressure also results in more water consumption.

Detailed ways

The foregoing and other features of the present application will become apparent from the following description, taken in conjunction with the accompanying drawings. In the description and drawings, specific embodiments of the present application are specifically disclosed, indicating some of the embodiments in which the principles of the present application may be employed. It is to be understood that the application is not limited to the described embodiments, but, on the contrary, This application includes all modifications, variations, and equivalents falling within the scope of the appended claims.

An embodiment of the first aspect of the present application provides a fluid injection device, as shown in Figures 1 and 2, including a first injection port 4. The converging chamber 3 and multiple first fluid pressurizing components 1. The inlet end of the first injection port 4 is connected to the converging chamber 3, and the outlet end of each first fluid pressurizing component 1 is connected to the converging chamber 3. And connected, the injection direction of each first fluid pressurizing component 1 converges on the same focus 301 (as shown in Figure 3). The focus 301 is located on the central axis 5. The focus 301 is also located in the convergence chamber 3. The first fluid The angle α between the injection direction of the pressurizing component 1 and the central axis 5 is greater than 0° and less than 90°. Along the direction of the central axis 5, each first fluid pressurizing component 1 is located on the same side of the focus 301, for example , each first fluid pressurizing component 1 is located on the lower side of the focus 301, as shown in Figure 3.

The first injection port 4, the convergence chamber 3 and the first fluid pressure increasing component 1 are connected in sequence. The injection direction of each first fluid pressure increasing component 1 converges at the same focus, and the injection direction of each first fluid pressure increasing component 1 The fluids all collide at the focus. In order to avoid excessive energy consumption in the impact, the angle between the injection direction of the first fluid pressurizing component 1 and the central axis 5 should be greater than 0° and less than 90°, so that the impact produces explosive high-speed small droplets passing by. After reflection on the surface of the convergence chamber 3, it is sprayed out from the first injection port 4. The first injection port 4 sprays high-speed atomized water droplets, which saves more water than the water jets in the prior art.

In this embodiment, a plurality of first fluid pressurizing components 1 are evenly spaced along the circumferential direction of the central axis 5, and the structure of each first fluid pressurizing component 1 is exactly the same. 1 is in a parallel relationship, the number of the first fluid pressurizing components 1 can be 2, 3, 4, 5 or 6, and each two first fluid pressurizing components 1 are mirror images of each other. The first fluid boosting component 1 can be an existing Tesla valve, boosting turbine pump or plunger pump.

In some embodiments, the number of first fluid pressurizing components 1 is 2 or more, the first fluid pressurizing component 1 is a Tesla valve, and the outlet end of the first fluid pressurizing component 1 is connected to the convergence chamber 3 connection, the length direction of the first fluid pressurizing component 1 is parallel to the central axis 5, and the two first fluid pressurizing components 1 are in a parallel relationship.

If the angle between the injection direction of the first fluid pressurizing component 1 and the central axis 5 is relatively large, the energy consumed by the impact of the fluid ejected from the first fluid pressurizing component 1 at the focus is relatively large, resulting in small droplets. The larger the number, the smaller the velocity of the droplets. If the angle between the injection direction of the first fluid pressurizing component 1 and the central axis 5 is small, the energy consumption of the fluid ejected from the first fluid pressurizing component 1 when it hits the focus is small, and the small droplets generated will The smaller the number, the smaller the speed of the droplets. In order to balance the contradiction between the number and speed of small droplets, the angle between the injection direction of the first fluid pressurizing component 1 and the central axis 5 is set to greater than or equal to 30° and less than or equal to 45°, especially When set to 45°, the number and speed of small droplets are better.

In this embodiment, a Tesla valve is used as the first fluid pressurizing component to cause the first injection port 4 to eject a pulse-type atomized water droplet flow.

Optionally, each first fluid pressurizing component 1 includes multiple (ie multi-stage) Tesla valves connected in series.

Optionally, a throttle valve can be connected to the outlet of each stage of the Tesla valve. Therefore, the fluid passes smoothly through the A flow channel of the Tesla valve. Due to the action of the throttle valve, the fluid flows through the B channel of the Tesla valve. The flow channel generates reverse flow. The fluid flowing back through the B flow channel and the fluid passing through the A flow channel merge and then flow to the output port. The fluids merge multiple times through the structure of multiple Tesla valves in series, which plays a role in intercepting and pressurizing the fluid. Through the joint action of multiple series-connected Tesla valves, throttle valves and convergence chambers 3, a fluid is formed. It uses a constant frequency of pressure release and supercharging to eject pulse-type supercharged atomized water droplets.

In some embodiments, the convergence chamber 3 may be a conical structure, the focus 301 is located on the axis of the conical structure, the axis of the conical structure is perpendicular to and intersects with the central axis 5 , and the axis of the first injection port 4 is The axes of the conical structures coincide with each other, and the inlet end of the first injection port 4 is connected to the convergence chamber 3. The volume of the convergence chamber 3 can be obtained through a limited number of experiments. Alternatively, the convergence chamber 3 can also be a spherical structure, with the focus 301 located at the center of the spherical structure. The axis of the first injection port 4 is perpendicular to and intersects with the central axis 5. The first injection port 4 can be a conical cylindrical structure or a straight tube. shape structure, as shown in Figures 3 and 4. When there are two first fluid pressurizing components 1, the central axis 5 and the injection directions of the two first fluid pressurizing components 1 are located in the same plane, and the plane is parallel to the paper surface of Figure 1 or Figure 2, and the first The axis of the injection port 4 may be parallel or perpendicular to the plane, that is, the axis of the first injection port 4 may be parallel or perpendicular to the paper surface of FIG. 3 .

In the prior art, shower heads contain multiple water spray holes. In order to pressurize, those skilled in the art generally believe that a smaller diameter of the water spray hole of the shower head is conducive to pressurization. For example, the diameter of the water spray hole is less than 1 mm. However, the inventor found that a smaller diameter of the water spray hole has the effect of supercharging. The effect of throttling increases the jet resistance, which is not conducive to water flow pressurization. The inventor overcame the technical prejudice in the field and creatively proposed that the fluid injection device has only one first injection port 4, and both the outlet end and the inlet end of the first injection port 4 are designed as completely transparent structures, that is, the first injection port 4 is designed to have a completely transparent structure. Neither the outlet end nor the inlet end of the first injection port 4 is provided with any blocking components. The outlet end of the first injection port 4 is not provided with small injection holes, small injection nozzles or filters, etc., which can block fluid from the outlet end of the first injection port 4. The ejection component thus avoids possible obstructions at the inlet end and outlet end of the first injection port 4. In addition, the first injection port 4 is not prone to clogging without a small injection hole. For example, the inner diameter of the inlet end A of the first injection port 4 may be 1 mm-6 mm. Further, the inner diameter of the inlet end A of the first injection port 4 may be 2.5 mm-3 mm. The inner diameter of the outlet end of the first injection port 4 and the third The length of a jet port 4 can be obtained through a limited number of tests, as shown in Figure 3.

In some embodiments, the first injection port 4 has a cone-shaped structure or a trumpet-shaped structure to eject a radial flow of atomized water droplets.

In some embodiments, the fluid injection device may further include a second injection port 6 , the inlet end of the second injection port 6 is connected and communicated with the convergence chamber 3 , and the axis of the second injection port 6 coincides with the axis of the central axis 5 , for example, the inner diameter of the inlet end B of the second injection port 6 can be 1mm-6mm, further, the inner diameter of the inlet end B of the second injection port 6 can be 2.5mm-3mm, along the direction of the central axis 5, the second injection port The port 6 and the first fluid pressurizing component 1 are respectively located on the upper and lower sides of the focus 301, as shown in Figures 2 and 3. The inner diameter of the outlet end of the second injection port 6 and the length of the second injection port 6 can be obtained through a limited number of experiments. The fluid injection device may also have only one second injection port 6 .

In order to avoid possible resistance caused by the outlet end and inlet end of the second injection port 6, the outlet end of the second injection port 6 has the same structure as the outlet end of the first injection port 4, and the inlet end of the second injection port 6 has the same structure as the first injection port 4. The structure of the inlet end of the port 4 is the same, that is, both the outlet end and the inlet end of the second injection port 6 are completely transparent. The fluid injection device may include both the first injection port 4 and the second injection port 6, or the fluid injection device may only include the first injection port 4 and the second injection port 6. First, when the fluid injection device only includes the second injection port 6, the second injection port 6 is the first injection port 4, as shown in Figures 1 to 4.

When the fluid injection device contains both the first injection port 4 and the second injection port 6, it is generally not recommended to use the first injection port 4 and the second injection port 6 at the same time. A first sealing plug 401 is provided in the first injection port 4 . The first sealing plug 401 is detachably connected to the first injection port 4 . The inner end surface of the first sealing plug 401 is in contact with the inner surface of the convergence chamber 3 . Matching, that is, the missing part of the inner surface of the convergence cavity 3 at the inner end of the first sealing plug 401 corresponds to the inner end surface of the first sealing plug 401 . The second injection port 6 is matched with a second sealing plug 601 . The second sealing plug 601 is detachably connected to the second injection port 6 . The inner end surface of the second sealing plug 601 is in contact with the inner surface of the convergence chamber 3 . Matching, that is, the missing part of the inner surface of the convergence cavity 3 at the inner end of the second sealing plug 601 corresponds to the inner end surface of the second sealing plug 601, as shown in FIG. 5 .

When there is no first sealing plug 401 in the first injection port 4, neither the outlet end nor the inlet end of the first injection port 4 has any obstruction. When there is no second sealing plug 601 in the second injection port 6, neither the outlet end nor the inlet end of the second injection port 6 has any obstruction. Both the first injection port 4 and the second injection port 6 have a conical cylindrical structure (the inner diameter of the outlet end is greater than the inner diameter of the inlet end) or a straight cylindrical structure (the inner diameter of the outlet end is equal to the inner diameter of the inlet end). 6 has only one outlet respectively. Compared with multiple small injection holes in the prior art, the resistance caused by the obstructions around the injection holes can be greatly reduced, and the supercharging effect is obvious.

In some embodiments, a plurality of first fluid pressurizing components 1 connected in parallel form a first pressurizing assembly. The fluid injection device further includes a housing 9 and a second pressurizing assembly. The second pressurizing assembly contains at least A second fluid pressurizing component 2, the second fluid pressurizing component 2 is a Tesla valve. When there are multiple second fluid pressurizing components 2 , the plurality of second fluid pressurizing components 2 may be in a parallel relationship. The first supercharging component and the second supercharging component are connected in series, and both the first supercharging component and the second supercharging component are located in the housing 9, as shown in Figures 1 and 2.

The inlet of the first pressurizing component corresponds to the inlet of the first fluid pressurizing component 1, the outlet of the first pressurizing component corresponds to the outlet of the first fluid pressurizing component 1, and the second pressurizing component The inlet of the assembly corresponds to the inlet of the second fluid pressurizing component 2 , and the outlet of the second pressurizing component corresponds to the outlet of the second fluid pressurizing component 2 . The inlet of the first pressurizing component is connected to the outlet of the second pressurizing component. The housing 9 is provided with a fluid inlet (ie, the inlet of the fluid injection device). The inlet of the second pressurizing component is connected to the inlet of the second pressurizing component. The fluid inlets are connected. Both the first injection port 4 and the second injection port 6 are connected to the housing 9 , and the convergence chamber 3 may be connected with a pressure relief valve to prevent excessive pressure from the first injection port 4 or the second injection port 6 from harming the human body.

In some embodiments, an injector 7 is provided between the first pressurizing component and the second pressurizing component. The injector 7 includes a jet inlet 701, a suction inlet 702, and a mixing outlet 703. The jet inlet 701 and The outlet of the second pressurizing component is connected, the mixing outlet 703 is connected with the inlet of the first pressurizing component, the suction inlet 702 is connected with the liquid supply component 8, and the liquid The supply assembly 8 contains a plurality of liquid supply units 801 connected in parallel, and the liquid supply units 801 can contain shower gel, shampoo, body lotion, etc., as shown in Figures 1 and 2 .

Since the outlet end of the second boosting component, the inlet end of the first injection port 4 and the inlet end of the second injection port 6 have the function of throttling, the water flow will be throttled, and at the same time, the fluid will be reversed in the Tesla valve. Due to the damping effect of the one-way valve, the gradually increasing water flow blocks the front cavity of the throttle, thereby gradually increasing the water pressure until it is balanced with the pressure of the tap water pump station, thereby achieving a low-flow boosting effect.

The working process of the fluid injection device is described below.

Fluid (gas or liquid) enters the fluid injection device from the inlet of the fluid injection device. The fluid enters the second pressurizing component, the ejector 7 and the first pressurizing component in sequence. Finally, the fluid passes through the first fluid pressurizing component. The fluid ejected from each first fluid pressurizing component 1 collides at the focus, thereby generating explosive high-speed fluid and ejecting it from the first injection port 4.

During this process, the second pressurizing component pressurizes the fluid for the first time, the ejector 7 pressurizes the fluid for the second time, and the second pressurizing component pressurizes the fluid for the third time.

When the fluid injected by the fluid injection device is gas (such as air), the fluid injection device may be a multi-stage pressurized gas nozzle. It can be seen that the fluid injection device can be used in a variety of different uses, and those skilled in the art can also expand its uses based on the inspiration of this application.
