Description

Technical Field

[0001] This invention belongs to the field of smart toilets and relates to a smart toilet nozzle with a spiral pulse massage washing effect. Background Technology

[0002] As human society continues to develop and living standards continue to improve, people are no longer satisfied with simple toilet needs and are pursuing a healthier and more comfortable toilet experience. As a popular water outlet device in smart toilets, the spray effect of the vortex nozzle determines whether people have a comfortable toilet experience.

[0003] Traditional swirling nozzles have several problems. First, their performance is greatly affected by structural dimensions, resulting in severe water flow dispersion and an inability to achieve a stable swirling water flow. The complex structural design also makes it easier for limescale to accumulate in the nozzle after prolonged use, causing poor water flow and easily reducing the nozzle's lifespan. Second, because most smart toilets use a columnar water outlet, the cleaning area of ​​the nozzle is small and the force is too strong, resulting in poor cleaning effect and a stinging sensation for the user. Third, conventional smart toilet nozzles use a standard isosceles triangle as an obstruction, which causes a loss of the water flow vortex street effect and affects the final swaying water outlet angle.

[0078] Example 1:

[0079] like Figure 1-5 As shown, a smart toilet nozzle with a spiral pulse massage flushing effect includes a body 1 and a component 3. The body 1 has a water inlet, an outlet, and a stepped water storage module. The component 3 has a spiral pressurization module, an oscillating module, and a gas-liquid mixing module. The component 3 is disposed on the body 1. The stepped water storage module, spiral pressurization module, oscillating module, and gas-liquid mixing module are sequentially connected between the water inlet and outlet of the body 1. The stepped water storage module is used to store water and pre-increase the water flow velocity. The spiral pressurization module is used to form a Karman vortex street in the water flow. The oscillating module is used to generate an oscillating water flow. The gas-liquid mixing module is used to mix the water flow with air to form a pulse jet.

[0080] The cascade water storage module includes several sequentially connected water inlet channels. The number of water inlet channels is set according to actual needs. For example, when the distance between the water inlet and outlet on the main body 1 is far, the number of water inlet channels can be appropriately increased, but generally not exceeding five. In this embodiment, the water inlet channels are provided in three stages, including a first water inlet channel 10, a second water inlet channel 11, and a third water inlet channel 14. The second water inlet channel 11 is located between the first water inlet channel 10 and the third water inlet channel 14 and is connected to both the first water inlet channel 10 and the third water inlet channel 14. The first water inlet channel 10 is connected to the water inlet of the main body 1, and the third water inlet channel 14 is connected to the spiral pressurization module. The water flows from the water inlet sequentially along the first water inlet channel 10, the second water inlet channel 11, and the third water inlet channel 14 to the spiral pressurization module. The first water inlet channel 10, the second water inlet channel 11, and the third water inlet channel 14 are the flow directions of the water.

[0081] The first water inlet channel 10, the second water inlet channel 11, and the third water inlet channel 14 are cylindrical. In this embodiment, the cross-sectional area of ​​the first water inlet channel 10, the second water inlet channel 11, and the third water inlet channel 14 gradually decreases, and the water flow velocity in each water inlet channel gradually increases, providing suitable water pressure and flow velocity for subsequent rinsing. Preferably, the length of the first water inlet channel 10 is 40mm-100mm, and the length of the remaining water inlet channels is not greater than the length of the first water inlet channel 10. The aperture of the first water inlet channel 10 is set to 10mm-64mm, and the aperture of the remaining water inlet channels is smaller than the aperture of the first water inlet channel 10. The aperture of the last water inlet channel is set to 6mm-16mm.

[0082] This embodiment limits the diameter of the water inlet channel:

[0083] The total number of inlet channels is set to h (h≤5), and the number of current inlet channels is set to m (m=1...h). hm is set as the m-th inlet channel when the total number of inlet channels is h. For example, when h=3 and m=1, h1 is the first inlet channel when the total number of inlet channels is 3. The inlet channel diameter is set to D, and the current inlet channel diameter is set to... When the diameter of the next stage inlet channel of the forward water channel is set to (When m = h, the current water inlet channel is the last stage water inlet channel, and there is no next stage water inlet channel at this time.)

[0084] When the ratio of the diameter of the inlet channel to the diameter of the next-stage inlet channel is limited to:

[0085]

[0086] In equation (1) above, n is set as a coefficient, n = h-1; Z is the aperture ratio. That is, the ratio of the diameter of the first inlet channel to the diameter of the last inlet channel.

[0087] In the above formula, the matching h is set according to the actual structure of the smart toilet nozzle. That is, for a certain smart toilet nozzle structure h, This is the set value.

[0088] According to the law of conservation of flow, the relationship between the current inlet channel orifice diameter and the water flow velocity, and the orifice diameters of adjacent inlet channels:

[0089]

[0090]

[0091] In equation (2) above, Let h be the cross-sectional area of ​​the m-th inlet channel when the total number of inlet channels is h. The water flow velocity in the m-th inlet channel when the total number of inlet channel stages is h. The fluid specific volume, i.e., the reciprocal of the water flow density, is the fluid density of the m-th inlet channel when the total number of inlet channels is h. They are respectively as well as The derivative; in this embodiment, the fluid flowing in the water inlet channel is water, which is approximately incompressible, therefore remain unchanged. The relationship between the inlet channel diameter and the water flow velocity can be expressed as:

[0092]

[0093] According to equation (4), the larger the diameter of the inlet channel, the smaller the water flow velocity.

[0094] In the above formula (3), Let h be the water pressure in the m-th inlet channel when the total number of inlet channels is h. Let h be the relative height of the water flow element in the m-th inlet channel when the total number of inlet channels is h. Let h be the water pressure in the (m+1)th inlet channel when the total number of inlet channels is h. The relative height of the water flow element in the (m+1)th inlet channel when the total number of inlet channels is h, ρ is the fluid density. Since the water flow is approximately an incompressible fluid, ρ is a constant, g is the gravitational acceleration, and Kw is the head loss when the water flows from the mth inlet channel to the (m+1)th inlet channel. In actual operation, the orifice diameter and flow velocity of each inlet channel can be set according to equations (4) and (5).

[0095] according to Figure 1 From a visual perspective, the second water inlet channel 11 and the third water inlet channel 14 are located on the lower side of the main body 1.

[0096] The spiral pressurization module includes a blocking block 2 and a constricted water flow channel 12. The two ends of the constricted water flow channel 12 are connected to the water inlet channel of the cascade water storage module and the oscillating swing module, respectively. The water flows along the water inlet channel of the cascade water storage module and the constricted water flow channel 12 to the oscillating swing module. The blocking block 2 is set in the constricted water flow channel 12.

[0097] The constricted water flow channel 12 includes a front end 121 connected to the cascade water storage module and a neck end 122 connected to the oscillating swing module. The diameter of the front end 121 is smaller than the diameter of the third water inlet channel 14. Water flows into the front end 121 from the third water inlet channel 14 and the water flow velocity is accelerated through the front end 121. The neck end 122 of the constricted water flow channel 12 is defined as circular and smaller than the front end 121, presenting a constricted structure. The constriction process is a smooth constriction structure. Water flows into the oscillating swing module along the front end 121 and the neck end 122, and the water flow velocity is further increased through the neck end 122.

[0098] Preferably, the diameter of the necked water flow channel 12 is 4mm-10mm.

[0099] The blocking block 2 is located at the front end 121 of the constricted flow channel 12. The blocking block 2 is a triangular pyramid structure, including a horizontal side and two sets of side sides. Figure 1 From a visual perspective, the horizontal edge is located at the bottom, directly facing the water inlet channel of the cascade water storage module. The horizontal edge is perpendicular or nearly perpendicular to the direction of water flow from the cascade water storage module to the front end 121 of the constricted water flow channel 12. The two sets of side edges are respectively set as concave arc surfaces. The setting of the blocking block 2 causes the flowing water to generate a Karman vortex street phenomenon, enhancing the spiral oscillation effect, and enabling the water flow reaching the fluid wall channel and the oscillating area to have a better oscillation effect. At the same time, setting the two sides of the blocking block 2 as concave arc surfaces, with the horizontal edge directly facing the water inlet channel of the cascade water storage module, solves the problem that the Karman vortex street phenomenon is not obvious when the space is small, and effectively improves the spiral oscillation degree of the water outlet.

[0100] The oscillating and swinging module includes a fluid-attached wall channel 20, a swinging fluid chamber 13, a fluid-attached wall block 5, a swinging feedback area 7, and a swinging water outlet 21. The lower ends of the fluid-attached wall channel 20 and the swinging fluid chamber 13 are connected to the constricted water flow channel 12, the upper end of the fluid-attached wall channel 20 is connected to the gas-liquid mixing module, the upper end of the swinging fluid chamber 13 is connected to the swinging feedback area 7, and the swinging feedback area 7 is connected to the swinging water outlet 21. The fluid-attached wall block 5 is fixed between the fluid-attached wall channel 20 and the swinging fluid chamber 13. There are two sets of fluid-attached wall blocks 5, which are symmetrically arranged around the center line of the fluid-attached wall channel 20. The inner wall of the fluid-attached wall block 5 in contact with the fluid-attached wall channel 20 is set as an inclined surface, and the angle α between the inner wall and the center line is set to a range of 9°-20°. Figure 1As shown, the two sets of fluid wall-attachment blocks 5 form a channel 20 that is smaller at the top and larger at the bottom. The contact corners between the fluid wall-attachment blocks 5 and the oscillating fluid chamber 13 are set as smooth rounded corners. The oscillating fluid chamber 13 provides enough space for the water flow to oscillate. Under the combined action of the oscillating fluid chamber 13 and the fluid wall-attachment blocks 5, the water splashing effect is achieved without any oscillating parts. The oscillation amplitude is large, the experience is good, and there is also a certain oscillation frequency. The oscillation feedback area 7 generates negative pressure to enhance the wall-attachment effect and achieve a stable waving water effect.

[0101] The oscillating water outlet 21 is designed as a frustum structure. The aperture of the oscillating water outlet 21 on the side of the oscillating module is smaller than that on the side of the gas-liquid mixing module, so as to appropriately reduce the flow rate and make the gas-liquid mixing in the gas-liquid mixing module more complete.

[0102] The gas-liquid mixing module includes a nozzle outlet 40, an air intake 30, and an outlet water flow channel 15. The nozzle outlet 40 and the air intake 30 are located above the outlet water flow channel 15 and are connected to the outlet water flow channel 15 on one side and to the outside through the outlet of the body 1 on the other side. The outlet water flow channel 15 is connected to the swing water flow outlet 21 of the oscillating swing module. The outlet water flow channel 15 is set as a flat cylindrical cavity, which serves as a gas-liquid mixing cavity to realize gas-liquid mixing.

[0103] Specifically, the water flow with oscillation caused by the oscillation module enters the outlet water flow channel 15 and flows to both sides of the cavity. During this process, the water flow collides with the upper wall of the cavity, generating vortex disturbance and forming a pulse negative pressure zone in a certain area. The air inlet 30 is located in the negative pressure zone and quickly draws in air, causing the water flow and the drawn-in air to meet and mix, generating a pulse effect at the same time.

[0104] The nozzle outlet 40 is designed as a frustum, with the lower circular radius being larger than the upper circular radius, and both the lower and upper circular radii being less than 10mm, in order to compensate for the reduced water flow velocity at the outlet of the oscillating module.

[0105] The air intake port 30 is provided in a plurality of manner, and the plurality of air intake ports 30 are arranged in a ring array with the nozzle outlet 40 as the center. The air intake port 30 is provided in a cylindrical structure with an aperture range of 0.5mm-1.8mm and a distance between the air intake port 30 and the nozzle outlet 40 ranging from 7.0mm to 18mm.

[0106] The implementation process of the intelligent toilet nozzle in this embodiment is as follows: Water flows from the inlet of the main body 1 to the stepped water storage module. The water flows sequentially along the first water inlet channel 10, the second water inlet channel 11, and the third water inlet channel 14. The cross-sectional area of ​​each water inlet channel gradually decreases, causing the water flow velocity in each water inlet channel to continuously increase, providing the set water pressure and flow velocity for flushing. The water then enters the spiral pressurization module. Passing through the blocking block 2, the water flow forms a Karman vortex street effect. The water flows through the constricted water flow channel 12, where the water pressure is further strengthened and it enters the oscillating module. At this time, most of the water flow oscillates about the fluid wall channel 20 due to the wall adhesion effect, while a small portion... Water flows through the oscillating fluid chamber 13 and merges with the wall-attached water flowing through the fluid wall-attached channel 20 via the oscillating feedback area 7. All water flows enter the gas-liquid mixing module from the oscillating water outlet 21. The water flows into the outlet water channel 15 and flows to both sides. The water flows into the outlet water channel 15 and collide with the upper wall of the outlet water channel 15, generating eddy current disturbance and forming a pulse negative pressure zone in a certain area. The air inlet 30 located in the negative pressure zone quickly draws in air, causing the water flow and the drawn-in air to meet and mix, generating a pulse effect. The gas-liquid mixed water flows out from the nozzle outlet 40 in a pulse, achieving a better massage effect while ensuring high comfort.

[0107] This application improves the overall water flow velocity through a tiered water storage module and a spiral pressurization module, further expands the water flow cleaning area with the help of an oscillating and swinging module, and achieves pulse jet cleaning while ensuring the cleaning effect through gas-liquid mixing, ultimately taking into account both the comfort and gentleness of the cleaning process.

[0108] This application optimizes and simplifies the structure of the smart toilet nozzle, effectively reducing the accumulation of limescale inside the nozzle due to the complexity of the structure itself during long-term use, reducing the occurrence of poor water flow caused by limescale accumulation, and improving the service life of the nozzle.

[0109] The intelligent toilet nozzle of this application is designed as an integrated structure, with fewer parts, a simple structure, and is easy to manufacture.

[0110] This application also provides a tiered water storage method for a smart toilet nozzle, which is based on the aforementioned tiered water storage module and specifically includes the following steps:

[0111] Step S1: Set up interconnected multi-stage water inlet channels;

[0112] Step S2: Setting the orifice diameter and flow rate of the multi-stage water inlet channel;

[0113] In step S1, the water inlet channel is provided in three stages, including a first water inlet channel 10, a second water inlet channel 11, and a third water inlet channel 14. The second water inlet channel 11 is located between the first water inlet channel 10 and the third water inlet channel 14 and is connected to both the first water inlet channel 10 and the third water inlet channel 14. The third water inlet channel 14 is connected to the spiral pressurization module. The water flows from the inlet sequentially along the first water inlet channel 10, the second water inlet channel 11, and the third water inlet channel 14 to the spiral pressurization module. The first water inlet channel 10, the second water inlet channel 11, and the third water inlet channel 14 are the flow directions of the water.

[0114] The first water inlet channel 10, the second water inlet channel 11, and the third water inlet channel 14 are cylindrical.

[0115] The cross-sectional areas of the first water inlet channel 10, the second water inlet channel 11, and the third water inlet channel 14 gradually decrease, and the water flow velocity in each water inlet channel gradually increases.

[0116] The length of the first water inlet channel 10 ranges from 40mm to 100mm, and the length of the other water inlet channels is no greater than the length of the first water inlet channel 10.

[0117] The aperture range of the first water inlet channel 10 is set to 10mm-64mm, and the apertures of the remaining water inlet channels are all smaller than the aperture of the first water inlet channel 10. The aperture range of the last water inlet channel is set to 6mm-16mm.

[0118] In step S2, the orifice diameter and flow velocity of the multi-stage water inlet channel are set as follows:

[0119] The total number of inlet channels is set to h (h≤5), and the number of current inlet channels is set to m (m=1...h). hm is set as the m-th inlet channel when the total number of inlet channels is h. For example, when h=3 and m=1, h1 is the first inlet channel when the total number of inlet channels is 3. The inlet channel diameter is set to D, and the current inlet channel diameter is set to... When the diameter of the next stage inlet channel of the forward water channel is set to (When m = h, the current water inlet channel is the last stage water inlet channel, and there is no next stage water inlet channel at this time.)

[0120] When the ratio of the diameter of the inlet channel to the diameter of the next-stage inlet channel is limited to:

[0121]

[0122] In the above formula, n is set as a coefficient, n = h-1; Z is the aperture ratio. That is, the ratio of the diameter of the first inlet channel to the diameter of the last inlet channel.

[0123] In the above formula, the matching h is set according to the actual structure of the smart toilet nozzle. That is, for a certain smart toilet nozzle structure h, This is the set value.

[0124] According to the law of conservation of flow, the relationship between the current inlet channel orifice diameter and the water flow velocity, and the orifice diameters of adjacent inlet channels:

[0125]

[0126]

[0127] In the above formula, Let h be the cross-sectional area of ​​the m-th inlet channel when the total number of inlet channels is h. The water flow velocity in the m-th inlet channel when the total number of inlet channel stages is h. The fluid specific volume, i.e., the reciprocal of the water flow density, is the fluid density of the m-th inlet channel when the total number of inlet channels is h. They are respectively as well as The derivative; in this embodiment, the fluid flowing in the water inlet channel is water, which is approximately incompressible, therefore remain unchanged. The relationship between the inlet channel diameter and the water flow velocity can be expressed as:

[0128]

[0129] According to the above formula, the larger the diameter of the water inlet channel, the smaller the water flow velocity.

[0130] In the above formula, Let h be the water pressure in the m-th inlet channel when the total number of inlet channels is h. Let h be the relative height of the water flow element in the m-th inlet channel when the total number of inlet channels is h. Let h be the water pressure in the (m+1)th inlet channel when the total number of inlet channels is h. The relative height of the water flow element in the (m+1)th inlet channel when the total number of inlet channels is h, ρ is the fluid density. Since the water flow is approximately an incompressible fluid, ρ is a constant, g is the gravitational acceleration, and Kw is the head loss when the water flows from the mth inlet channel to the (m+1)th inlet channel. In actual operation, the orifice diameter and flow velocity of each inlet channel can be set according to equations (4) and (5).

[0131] This application also provides a method for preparing a smart toilet nozzle with a spiral pulse massage washing effect. This method is based on the aforementioned smart toilet nozzle, which includes a stepped water storage module, a spiral pressurization module, an oscillating module, and a gas-liquid mixing module located within the main body. The stepped water storage module, spiral pressurization module, oscillating module, and gas-liquid mixing module are connected and arranged accordingly. The method specifically includes the following steps:

[0132] Step 1: The cascade water storage module is used to store water and pre-increase the water flow rate;

[0133] Step 2: The spiral pressurization module is used to form a Karman vortex street in the water flow from the cascade water storage module;

[0134] Step 3: The oscillating swing module is used to generate an oscillation in the water flow that comes in from the spiral pressurization module;

[0135] Step 4: The gas-liquid mixing module is used to mix the water flow from the oscillating module with air to form a pulse jet, which is then sprayed outwards;

[0136] In step 1, the cascade water storage module includes several sequentially connected water inlet channels, and the aperture of each water inlet channel is set.

[0137] The diameter of the water inlet channel is limited to:

[0138]

[0139] The total number of inlet channels is set to h (h≤5), and the number of current inlet channels is set to m (m=1...h). hm is set as the m-th inlet channel when the total number of inlet channels is h. For example, when h=3 and m=1, h1 is the first inlet channel when the total number of inlet channels is 3. The inlet channel diameter is set to D, and the current inlet channel diameter is set to... When the diameter of the next stage inlet channel of the forward water channel is set to (When m = h, the current water inlet channel is the last water inlet channel, and there is no next water inlet channel at this time);

[0140] In the above formula, n is set as a coefficient, n = h-1; Z is the aperture ratio. That is, the ratio of the diameter of the first inlet channel to the diameter of the last inlet channel.

[0141] In the above formula, the matching h is set according to the actual structure of the smart toilet nozzle. That is, for a certain smart toilet nozzle structure h, This is the set value.

[0142] The relationship between the inlet channel diameter and the water flow velocity in step 1 is as follows:

[0143]

[0144]

[0145] In the above formula, Let h be the cross-sectional area of ​​the m-th inlet channel when the total number of inlet channels is h. vh represents the flow velocity of the m-th inlet channel when the total number of inlet channels is h; m The fluid specific volume, i.e., the reciprocal of the water flow density, is the fluid density of the m-th inlet channel when the total number of inlet channels is h. They are respectively as well as The derivative; in this embodiment, the fluid flowing in the water inlet channel is water, which is approximately incompressible, therefore remain unchanged. The relationship between the inlet channel diameter and the water flow velocity can be expressed as:

[0146]

[0147] According to the above formula, the larger the diameter of the water inlet channel, the smaller the water flow velocity.

[0148] Let h be the water pressure in the m-th inlet channel when the total number of inlet channels is h. Let h be the relative height of the water flow element in the m-th inlet channel when the total number of inlet channels is h. Let h be the water pressure in the (m+1)th inlet channel when the total number of inlet channels is h. Let h be the relative height of the water flow element in the (m+1)th inlet channel when the total number of inlet channels is h, ρ be the fluid density (ρ is a constant since water is approximately incompressible), g be the acceleration due to gravity, and Kw be the head loss when the water flows from the mth inlet channel to the (m+1)th inlet channel. In actual operation, the orifice diameter and flow velocity of each inlet channel can be set according to the above formula.

[0149] In step 2, the spiral pressurization module includes a blocking block 2 and a constricted water flow channel 12. The two ends of the constricted water flow channel 12 are connected to the water inlet channel of the cascade water storage module and the oscillating swing module, respectively. The water flows along the water inlet channel of the cascade water storage module and the constricted water flow channel 12 to the oscillating swing module. The blocking block 2 is set in the constricted water flow channel 12.

[0150] The constricted water flow channel 12 includes a front end 121 connected to the cascade water storage module and a neck end 122 connected to the oscillating swing module. The diameter of the front end 121 is smaller than the diameter of the third water inlet channel 14. Water flows into the front end 121 from the third water inlet channel 14 and the water flow velocity is accelerated through the front end 121. The neck end 122 of the constricted water flow channel 12 is defined as circular and smaller than the front end 121, presenting a constricted structure. The constriction process is a smooth constriction structure. Water flows into the oscillating swing module along the front end 121 and the neck end 122, and the water flow velocity is further increased through the neck end 122.

[0151] The blocking block 2 is located at the front end 121 of the constricted flow channel 12. The blocking block 2 is a triangular pyramid structure, including a horizontal side and two sets of side sides. Figure 1 From a visual perspective, the horizontal edge is located at the bottom, directly facing the water inlet channel of the cascade water storage module. The horizontal edge is perpendicular or approximately perpendicular to the direction of water flow from the cascade water storage module to the front end 121 of the constricted water flow channel 12. The two sets of side edges are respectively set as concave arc surfaces. The setting of the blocking block 2 causes the flowing water to generate a Karman vortex street phenomenon, enhancing the spiral swaying effect and enabling the water flow reaching the fluid wall channel and the swaying area to have a better swaying effect. At the same time, setting the two sides of the blocking block 2 as concave arc surfaces, with the horizontal edge directly facing the water inlet channel of the cascade water storage module, solves the problem that the Karman vortex street phenomenon is not obvious when the space is small, and effectively improves the spiral swaying degree of the water outlet.

[0152] Step 3's oscillating module includes a fluid wall-attached channel 20, an oscillating fluid chamber 13, a fluid wall-attached block 5, an oscillating feedback area 7, and an oscillating water outlet 21. The lower ends of the fluid wall-attached channel 20 and the oscillating fluid chamber 13 are connected to the constricted water flow channel 12, the upper end of the fluid wall-attached channel 20 is connected to the gas-liquid mixing module, the upper end of the oscillating fluid chamber 13 is connected to the oscillating feedback area 7, and the oscillating feedback area 7 is connected to the oscillating water outlet 21. The fluid wall-attached block 5 is fixed between the fluid wall-attached channel 20 and the oscillating fluid chamber 13. There are two sets of fluid wall-attached blocks 5, which are symmetrically arranged around the center line of the fluid wall-attached channel 20. The inner wall of the fluid wall-attached block 5 in contact with the fluid wall-attached channel 20 is set as an inclined surface, and the angle α between the inner wall and the center line is set to a range of 9°-20°. Figure 1 As shown, the two sets of fluid wall-attachment blocks 5 form a channel 20 that is smaller at the top and larger at the bottom. The contact corners between the fluid wall-attachment blocks 5 and the oscillating fluid chamber 13 are set as smooth rounded corners. The oscillating fluid chamber 13 provides enough space for the water flow to oscillate. Under the combined action of the oscillating fluid chamber 13 and the fluid wall-attachment blocks 5, the water splashing effect is achieved without any oscillating parts. The oscillation amplitude is large, the experience is good, and there is also a certain oscillation frequency. The oscillation feedback area 7 generates negative pressure to enhance the wall-attachment effect and achieve a stable waving water effect.

[0153] The oscillating water outlet 21 is designed as a frustum structure. The aperture of the oscillating water outlet 21 on the side of the oscillating module is smaller than that on the side of the gas-liquid mixing module, so as to appropriately reduce the flow rate and make the gas-liquid mixing in the gas-liquid mixing module more complete.

[0154] In step 4, the gas-liquid mixing module includes a nozzle outlet 40, an air intake 30, and an outlet water flow channel 15. The nozzle outlet 40 and the air intake 30 are located above the outlet water flow channel 15 and are connected to the outlet water flow channel 15 on one side and to the outside through the outlet of the body 1 on the other side. The outlet water flow channel 15 is connected to the swing water flow outlet 21 of the oscillating swing module. The outlet water flow channel 15 is set as a flat cylindrical cavity, which serves as a gas-liquid mixing cavity to achieve gas-liquid mixing.

[0155] Specifically, the water flow with oscillation caused by the oscillation module enters the outlet water flow channel 15 and flows to both sides of the cavity. During this process, the water flow collides with the upper wall of the cavity, generating vortex disturbance and forming a pulse negative pressure zone in a certain area. The air inlet 30 is located in the negative pressure zone and quickly draws in air, causing the water flow and the drawn-in air to meet and mix, generating a pulse effect at the same time.

[0156] The nozzle outlet 40 is designed as a frustum, with the lower circular radius being larger than the upper circular radius, and both the lower and upper circular radii being less than 10mm, in order to compensate for the reduced water flow velocity at the outlet of the oscillating module.

[0157] The air intake port 30 is provided in a plurality of manner, and the plurality of air intake ports 30 are arranged in a ring array with the nozzle outlet 40 as the center. The air intake port 30 is provided in a cylindrical structure with an aperture range of 0.5mm-1.8mm and a distance between the air intake port 30 and the nozzle outlet 40 ranging from 7.0mm to 18mm.
