The shell is provided with a flow channel. The adjusting assembly is connected with the shell and comprises a first moving part and a second moving part which are arranged at intervals along the axial direction of the flow channel. The first moving part is connected with the shell and can extend into the flow channel to adjust the opening degree of the flow channel. The second moving part is arranged in the flow channel and is provided with a communication port through which water flows.

Description

Technical Field

[0001] This invention relates to the field of textile weaving technology, and in particular to a valve body structure, a water spraying system, and a valve body structure control method. Background Technology

[0002] The function of the weft insertion mechanism is to guide the weft yarn into the shed so that it can interweave with the warp yarns to form a fabric. The weft insertion mechanism of a water jet loom uses water as a carrier, relying on the friction between the jet of water and the yarn to guide the weft yarn into the shed.

[0003] A novel water-jet weft insertion mechanism has been developed, which directly controls the water jet by controlling a pump located on the loom, thus decoupling the water jet motion from the spindle motion. However, existing water-jet weft insertion mechanisms lack valves near the nozzles, or the valves provided only function to open and close the water inlet. Vibrations generated by the loom's movement can cause the water pressure and flow rate at the nozzles to fall short of requirements, affecting product yield. Furthermore, each loom requires a separate water tank and pump, resulting in high costs and difficulties in unified control. Summary of the Invention

[0004] The main objective of this invention is to provide a valve body structure that aims to maintain stable water pressure, flow rate, and velocity, thereby improving product yield.

[0005] To achieve the above objectives, the valve body structure proposed in this invention includes:

[0006] A housing, the housing being provided with flow channels; and

[0007] An adjustment assembly is connected to the housing and includes a first moving part and a second moving part spaced apart along the axial direction of the flow channel.

The first driving part is connected to the first moving part to drive the first moving part to move radially along the flow channel, and the second driving part is connected to the second moving part to drive the second moving part to move axially along the flow channel.

Each of the multiple branch pipelines corresponds to one of the multiple water spraying mechanisms. One end of each branch pipeline is connected to the main pipeline, and the other end is connected to the water inlet end of the flow channel.

[0019] The present invention also proposes a control method for a valve body structure as described in any of the preceding claims, the control method comprising:

[0020] Obtain historical information about the outlet end of the flow channel;

[0021] The historical information is compared with the preset information to obtain the comparison result;

[0022] Based on the comparison results, control the movement of the first moving part and / or the second moving part.

[0023] In one embodiment, the preset information includes a preset threshold, and the step of controlling the movement of the first moving part and / or the second moving part according to the comparison result includes:

[0051] To achieve the goal of maintaining stable water pressure and flow rate and improving product yield, this invention proposes a valve body structure 100.

[0052] In some embodiments of this application, the valve body structure 100 is applied to the nozzle 210 of the water jet loom 2. One end of the valve body structure 100 is connected to a water source, and the other end is connected to the nozzle 210. A pressure thread device is provided near the nozzle 210. When the nozzle 210 sprays water, it drives the weft thread drawn out from the pressure thread device to move.

[0053] Reference Figure 1 The valve body structure 100 includes a housing 10 and an adjustment assembly 30. The housing 10 is provided with a flow channel 10a. The adjustment assembly 30 is connected to the housing 10 and includes a first moving part 33 and a second moving part 37 arranged axially along the flow channel 10a. The first moving part 33 is connected to the housing 10 and can extend into the flow channel 10a to adjust the opening of the flow channel 10a. The second moving part 37 is provided in the flow channel 10a and is provided with a connecting port 37a through which water flows. The second moving part 37 can reciprocate along the axial direction of the flow channel 10a.

[0054] In one embodiment, the housing 10 is provided with an inlet and an outlet, which are connected by a flow channel 10a. The inlet is connected to a high-pressure water source, and the outlet is connected to a nozzle 210. The high-pressure water source can enter the flow channel 10a from the inlet, pass through the communication port 37a of the second moving part 37, and flow through the outlet to the nozzle 210 when the first moving part 33 is opened, and be sprayed out from the nozzle 210.

[0055] In this embodiment, the shape and extension trajectory of the flow channel 10a are not limited. Preferably, the inlet and outlet are located on opposite sides of the housing 10, the flow channel 10a extends along the length of the housing 10 and connects the inlet and outlet, and its extension trajectory is approximately a straight line to reduce the obstruction of the high-pressure water source by the wall of the flow channel 10a and improve efficiency.

[0056] Specific reference Figure 1 At least a portion of the first movable part 33 can extend into the flow channel 10a, and the opening degree of the flow channel 10a and the flow of water can be controlled by adjusting the position of the first movable part 33. Different opening degrees of the flow channel 10a will have different effects on the water source. Understandably, when the area of ​​the outlet end of the flow channel 10a remains unchanged, when the opening degree of the flow channel 10a at the first movable part 33 is larger, the water pressure at the outlet end is larger, and the flow rate and velocity are also larger. When the opening degree of the flow channel 10a at the first movable part 33 is smaller, the water pressure at the outlet end is smaller, and the flow rate and velocity are also smaller.

[0057] Optionally, the first moving part 33 can move radially along the flow channel 10a, with one end extending into the flow channel 10a. Through its radial movement, the length of the portion extending into the flow channel 10a can be adjusted to achieve different opening degrees of the flow channel 10a. When the portion extending into the flow channel 10a is long enough that one end abuts against the wall of the flow channel 10a, the water flow is completely blocked by the first moving part 33, and the nozzle 210 stops spraying water. As it moves radially, the portion extending into the flow channel 10a can gradually shorten, and the opening degree can gradually increase.

[0058] In other embodiments, the first moving part 33 can also move by rotation or eccentric rotation to change the opening of the flow channel 10a. For example, the first moving part 33 is generally plate-shaped, with an area greater than or equal to the opening area of ​​the flow channel 10a at that location. One side of the first moving part 33 is rotatably connected to the housing 10 and rotates around this center. During rotation, the first moving part 33 gradually enters the flow channel 10a, the opening of the flow channel 10a gradually changes, and at a certain angle, the plate surface can completely block the flow channel 10a, achieving the effect of flow interruption.

[0059] Refer to again Figure 1The second moving part 37 and the first moving part 33 form a chamber with the wall of the flow channel 10a. The size of the chamber can be adjusted when the second moving part 37 moves, thereby adjusting the flow rate and velocity. In this embodiment, the second moving part 37 is located near the water inlet end of the flow channel 10a. The chamber is connected to the flow channel 10a through the connecting port 37a at the second moving part 37 and the opening formed by the first moving part 33 and the wall of the flow channel 10a. The second moving part 37 moves along the axial direction of the flow channel 10a. When the second moving part 37 is close to the first moving part 33, the chamber becomes smaller, and the second moving part 37 generates a certain pumping pressure on the water flow in the chamber, increasing its velocity and consequently increasing the flow rate at the outlet. When the second moving part 37 moves away from the first moving part 33, the pumping pressure on the water flow is instantly weakened, thereby reducing the water velocity and consequently reducing the flow rate at the outlet.

[0060] In simple terms, the second moving part 37 can be likened to a piston. Understandably, the opening area of ​​the connecting port 37a is smaller than that of the flow channel 10a. The second moving part 37 still has a considerable contact area with the water flow. Therefore, when the second moving part 37 moves, it can still play a certain role in pumping the water flow and thereby regulate the flow rate.

[0061] Optionally, the travel distance of the second moving part 37 can be set according to actual conditions. In one embodiment, the first moving part 33 is used as the main regulator, that is, the opening of the flow channel 10a is adjusted by the first moving part 33 to make significant main adjustments to parameters such as water pressure, flow rate, and flow velocity. Based on this, a relatively limited travel distance of the second moving part 37 is set, and fine-tuning is performed by the movement of the second moving part 37. The first moving part 33 and the second moving part 37 work together to stabilize parameters such as water pressure, flow rate, and flow velocity within a suitable range. In this way, while having a good adjustment effect, the response of the second moving part 37 is also faster, making it more suitable for actual working conditions requiring high-speed adjustment.

[0062] Of course, when the stroke of the second moving part 37 is long enough, it will also have a greater effect on the above parameters, and specific settings can be made according to the actual situation.

[0063] Optionally, the first moving part 33 and the second moving part 37 can be controlled together by the same drive device, or they can be controlled independently by different drives. Thus, the first moving part 33 and the second moving part 37 can operate independently or simultaneously to adjust the parameters of the flow channel 10a, depending on the situation. For example, in practical applications, each time water is sprayed, the first moving part 33 opens to a suitable degree, while the second moving part 37 can remain stationary or can be moved and adjusted in real time during the water spraying process.

[0064] Preferably, both the first moving part 33 and the second moving part 37 can be controlled by electrical signals to facilitate motion control of both and parameter adjustment of the flow channel 10a.

[0065] The technical solution of this application provides a valve body structure 100. The housing 10 of the valve body structure 100 is provided with a flow channel 10a. The opening of the flow channel 10a is adjusted by a first moving part 33 that can extend into the flow channel 10a. The size of the chamber between the first moving part 33 and the second moving part 37 is adjusted by a second moving part 37 that is provided in the flow channel 10a and can move along the axial direction of the flow channel 10a. By controlling the first moving part 33 and the second moving part 37, the pressure, flow rate and other parameters at the outlet end of the flow channel 10a can be stabilized within a suitable range.

[0066] When the valve body structure 100 is applied to the weft insertion of the loom 2, the water outlet of the flow channel 10a is connected to the nozzle 210. Understandably, parameters such as water pressure, flow rate, and velocity will affect the distance of the sprayed water, thereby affecting the length of the inserted weft yarn. When the above parameters do not meet the requirements, the length of the weft yarn often cannot fully meet the requirements. Therefore, when the valve body structure 100 of this application is applied to the weft insertion of the loom 2, it can make the nozzle 210 have more stable water pressure and flow rate when spraying water, thereby reducing the error of weft insertion and improving the yield of the fabric.

[0067] Reference Figure 1 In one embodiment, the second moving part 37 is located on the side of the first moving part 33 away from the water outlet end of the flow channel 10a.

[0068] In this embodiment, the second moving part 37 is located near the water inlet end of the flow channel 10a. When the second moving part 37 approaches the first moving part 33, the chamber between the first moving part 33 and the second moving part 37 becomes smaller. The second moving part 37 exerts a certain pumping pressure on the water flow in the chamber, increasing its flow velocity and consequently increasing the flow rate at the outlet end. When the second moving part 37 moves away from the first moving part 33, it momentarily weakens the pumping pressure on the water flow, thereby reducing the water flow velocity and consequently reducing the flow rate at the outlet end.

[0069] In this embodiment, the second moving part 37 is located on the side of the first moving part 33 away from the water outlet end of the flow channel 10a. The water in the chamber flows through the opening formed between the first moving part 33 and the wall of the flow channel 10a to the water outlet end. This arrangement can reduce the disturbance of the second moving part 37 to the water flow near the water outlet end, and can make the water pressure, flow rate and velocity at the water outlet end of the flow channel 10a more stable and easier to adjust.

[0070] Of course, the embodiments of this application are not limited to this. The second moving part 37 can also be disposed on the side of the first moving part 33 near the outlet end of the flow channel 10a. Understandably, when the second moving part 37 moves away from the first moving part 33, the cavity between the second moving part 37 and the outlet end of the flow channel 10a becomes smaller, and the second moving part 37 exerts a certain pumping pressure on the water flow within the cavity, increasing its flow velocity and consequently increasing the flow rate at the outlet end. When the second moving part 37 moves closer to the first moving part 33, the cavity between the second moving part 37 and the outlet end of the flow channel 10a becomes larger, and the second moving part 37 obstructs the water flow from the first moving part 33, weakening the pumping pressure on the water flow towards the outlet end, thereby reducing the water flow velocity and consequently reducing the flow rate at the outlet end.

[0071] Furthermore, in one embodiment, the adjusting component 30 includes two second moving parts 37, which are spaced apart along the axial direction of the flow channel 10a and located on both sides of the first moving part 33. One second moving part 37 is provided on each side of the first moving part 33, wherein the two second moving parts 37 can move simultaneously and synchronously in the same direction to simultaneously adjust the water flow conditions on both sides of the first moving part 33. Of course, the two second moving parts 37 can also move independently; for example, when one second moving part 37 moves, the other second moving part 37 remains stationary; or, for example, the two second moving parts 37 can move towards each other or away from each other simultaneously.

[0072] Understandably, the cooperation between the first moving part 33 and the two second moving parts 37 will enable more diverse and refined adjustments to the water flow through more varied movements, thereby further improving the stability of parameters such as water pressure, flow rate, and velocity at the outlet of the flow channel 10a.

[0073] Reference Figure 1 In some embodiments, the adjustment assembly 30 further includes a first driving part 31 and a second driving part 35, both of which are connected to the housing 10. The first driving part 31 is connected to the first moving part 33 to drive the first moving part 33 to move radially along the flow channel 10a, and the second driving part 35 is connected to the second moving part 37 to drive the second moving part 37 to move axially along the flow channel 10a.

[0074] In this embodiment, the first moving part 33 and the second moving part 37 can be driven by the first driving part 31 and the second driving part 35 respectively, thereby enabling the first moving part 33 and the second moving part 37 to move independently. Thus, the first moving part 33 and the second moving part 37 can achieve various combinations, allowing for more diversified adjustment of the water flow and further improving the stability of the water flow at the outlet of the flow channel 10a. Specifically, the first driving part 31 drives the first moving part 33 to move radially, and the opening of the flow channel 10a can be more easily controlled by controlling the length of the portion extending into the flow channel 10a.

[0075] Specifically, in one embodiment, the housing 10 is provided with an adjustment channel 10b that communicates with the flow channel 10a. The adjustment channel 10b extends radially along the flow channel 10a. The first drive unit 31 is provided with a first stator. The first stator is arranged around the adjustment channel 10b. The first moving part 33 is movably disposed in the adjustment channel 10b. The first stator is used to drive the first moving part 33 to move.

[0076] Combined with reference Figure 1 In this embodiment, when the axis of the flow channel 10a is horizontally set, the adjustment channel 10b is located above the flow channel 10a and communicates with it. The first moving part 33 is movably disposed within the adjustment channel 10b to extend into the flow channel 10a or retract from the flow channel 10a to the adjustment channel 10b. This embodiment employs an electromagnetic drive method. The first stator includes a first electromagnetic coil, which is arranged around the adjustment channel 10b. When the current of the first electromagnetic coil changes, the magnetic field at the adjustment channel changes, driving the first moving part 33 to move. This embodiment uses electromagnetic induction to drive the first moving part 33, which facilitates control of the first moving part 33 and allows for linear adjustment of the opening of the flow channel 10a. Adjusting the appropriate opening of the flow channel 10a according to actual needs is beneficial for water flow control.

[0077] In this embodiment, the first moving part 33 is the first moving element, which makes the structure more compact and the integration higher.

[0078] Of course, the first drive unit 31 can also be driven by other drive methods such as a flat linear motor, which will not be limited here.

[0079] Furthermore, the housing 10 is provided with a connecting flow channel 10a and an adjustment groove extending along the axial direction of the flow channel 10a. The second drive unit 35 is provided with a second stator, which is arranged around the flow channel 10a. The second moving part 37 partially passes through the adjustment groove, and the second stator is used to drive the second moving part 35 to move.

[0080] In this embodiment, the second stator includes a second electromagnetic coil, which is arranged around the flow channel 10a. The second driving part 35 is the second moving part, and its driving principle and beneficial effects are similar to those of the first stator and the first moving part 33, so they will not be described in detail.

[0081] It is understood that a sealing plate is provided at the adjustment groove, and the sealing plate can move with the second moving part 37 to ensure the sealing at that location.

[0082] Of course, the second drive unit 35 can also be driven by other drive methods such as a flat linear motor, which will not be limited here.

[0083] It is understood that in this embodiment, the first driving unit 31 may use an electromagnetic driving method, while the second driving unit 35 may use other linear driving methods; or the first driving unit 31 may use other linear driving methods, while the second driving unit 35 may use an electromagnetic driving method. Of course, to facilitate rapid and precise control of the movement of the first moving unit 33 and the second moving unit 37, it is preferable that both the first moving unit 33 and the second moving unit 37 use electromagnetic driving methods.

[0084] In other embodiments of this application, the first moving part 33 and the second moving part 37 may be driven by the same driving device. For example, a combination of pneumatic and spring mechanisms can be used to connect the first moving part 33 and the second moving part 37 to two valves while ensuring airtightness. The movement of the first moving part 33 and the second moving part 37 is controlled by air pressure, the movement state is maintained by springs, and the start and stop of the first moving part 33 and the second moving part 37 are adjusted by opening and closing the air valves.

[0085] In one embodiment, the second moving part 37 is an adjusting plate. In this embodiment, the movement of the adjusting plate affects the water flow. On the one hand, provided that the strength is sufficient, the plate is thin and small in volume, so it has little impact on the water flow on both sides. On the other hand, the surface of the adjusting plate has a large contact area with the water flow, which can achieve a good pumping effect.

[0086] Optionally, the connecting port 37a is located in the middle of the regulating plate, and its shape is not limited. It is preferably a circular hole, and its axis can coincide with the axis of the flow channel 10a, so as to minimize the obstruction to the water flow while achieving the regulating function. Alternatively, the connecting port 37a can also be formed by the regulating plate and the wall of the flow channel 10a. The regulating plate can be connected to the second moving element on one side and spaced apart from the wall of the flow channel 10a on the other side to form the connecting port 37a. Its shape is not limited.

[0087] Reference Figure 2The present invention also proposes a water spraying system 1, applied to at least one loom 2. The water spraying system 1 includes multiple water spraying mechanisms 200, with each loom 2 corresponding to at least one water spraying mechanism 200. Each water spraying mechanism 200 includes a valve body structure 100 and a nozzle 210. The specific structure of the valve body structure 100 is as described in the above embodiments. The inlet end of the flow channel 10a of the valve body structure 100 is connected to a water source, and the nozzle 210 is connected to the outlet end of the flow channel 10a. Since this water spraying system 1 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0088] In one embodiment, the water spraying system 1 further includes a pumping device and a delivery pipeline. The delivery pipeline includes a main pipeline 300 and a plurality of branch pipelines 400. The main pipeline 300 is connected to the output end of the pumping device. The plurality of branch pipelines 400 correspond one-to-one with a plurality of water spraying mechanisms 200. One end of the branch pipeline 400 is connected to the main pipeline 300, and the other end is connected to the water inlet end of the flow channel 10a.

[0089] In this embodiment, centralized high-pressure water supply is provided through the main pipeline 300 connected to the pump pressure device, offering a high-pressure water flow within a certain pressure range. This facilitates centralized control of the water pressure of the multiple spray mechanisms 200 connected to the main pipeline 300. When it is necessary to add or remove spray mechanisms 200, simply connect the spray mechanism 200 to the main pipeline 300 through a branch pipeline 400 or disconnect a branch pipeline 400, making system expansion and pipeline modification more flexible. In specific applications, valve switches can be used at the connection points between the main pipeline 300 and the branch pipeline 400 to facilitate control of the water flow in the branch pipeline 400.

[0090] The water spray system 1 of this application supplies water to the main pipeline 300 through a pump, and then connects multiple water spray units 200 to the main pipeline 300, so that one pump can provide a high-pressure water source to multiple water spray units 200, which is low cost. Moreover, the multiple water spray units 200 are connected to the same high-pressure water source, which facilitates unified control.

[0091] Optionally, refer to Figure 2 The loom 2 can be equipped with multiple water spraying mechanisms 200. The multiple water spraying mechanisms 200 are connected to the main pipeline 300 through multiple branch pipelines 400. By performing time-division control on the valve body structure 100, the selection of different nozzle colors and the operation of water spraying and weft insertion can be realized.

[0092] Reference Figure 2 The water spraying mechanisms 200 of multiple looms 2 are all connected to the main pipeline 300. By adjusting parameters such as water pressure in the main pipeline 300, the water spraying mechanisms 200 of multiple looms 2 can be uniformly controlled. Of course, the valve body structure 100 of each water spraying mechanism 200 can be controlled independently to achieve different fabric requirements.

[0093] Reference Figures 3 to 9 The present invention also proposes a control method for the valve body structure 100 as described in any of the above claims, the control method comprising:

[0094] Step S100: Obtain historical information of the outlet end of flow channel 10a;

[0095] Step S200: Compare historical information with preset information to obtain comparison results;

[0096] Step S300: Based on the comparison result, control the movement of the first moving part 33 and / or the second moving part 37.

[0097] This invention acquires historical information from the outlet of flow channel 10a and adjusts the valve body structure 100 based on the fluid parameter changes reflected in the historical information. This stabilizes parameters such as water pressure, flow rate, and velocity at the outlet of flow channel 10a within a suitable range to meet actual needs. Historical information refers to parameter information from the previous one or several water spraying operations. Taking the historical information reflecting the parameters of the previous water spraying as an example, the historical information includes the pressure, flow rate, velocity, and position information of each part at the outlet of flow channel 10a during the previous water spraying. Preset information refers to parameters set manually or intelligently during a single weaving process or over a period of time. This includes target pressure, target flow rate, velocity, and preset ranges of variation to achieve the desired effect.

[0098] Understandably, when the above-mentioned water spraying system 1 is applied to the loom 2, the main pipeline 300 provides a pressure value close to the target pressure to each valve body structure 100. During the operation of the loom 2, factors such as the vibration of the loom 2 or the pressure fluctuation of the main pipeline 300 may cause changes in the water pressure, flow rate and velocity at the outlet of the flow channel 10a. Therefore, before each water spraying, it is necessary to compare the historical information obtained above with the preset information, and to control the movement of the first moving part 33 and / or the second moving part 37 as appropriate based on the comparison results, so that the parameters such as water pressure, flow rate and velocity meet the requirements.

[0099] Pressure and flow rate information can be obtained directly from the sensor located at the outlet of the flow channel 10a, while historical location information can be obtained from the signals recorded in the system.

[0100] The control method provided by the present invention can effectively control the first moving part 33 and the second moving part 37, so that parameters such as water pressure, flow rate and velocity during water spraying can be kept stable.

[0101] Reference Figure 4 In one embodiment, the preset information includes a preset threshold, and the step of controlling the movement of the first moving part 33 and / or the second moving part 37 according to the comparison result includes:

[0102] Step S301: Obtain the historical position information of the first moving part and the second moving part;

[0103] Step S310: Determine whether the comparison result exceeds the preset threshold;

[0104] Step S320: When the comparison result does not exceed the preset threshold, maintain the historical positions of the first moving part 33 and the second moving part 37 according to the historical position information;

[0105] Step S330: When the comparison result exceeds the preset threshold, target position information is generated based on the comparison result and historical position information, and the first moving part 33 and / or the second moving part 37 are controlled to move to the target position based on the target position information.

[0106] A preset threshold refers to a set range of parameter variations that meets the requirements. Taking pressure information as an example, the preset information includes target pressure information and a first preset threshold. Optionally, both historical pressure information and target pressure information are numerical information. Comparing historical pressure information with target pressure information means subtracting the two to obtain the pressure difference value.

[0107] The first preset threshold can be a range of pressure difference values. In this case, if the pressure difference exceeds the range of the first preset threshold, the comparison result is determined to exceed the preset threshold; conversely, if the pressure difference is within the range of the first preset threshold, the comparison result is determined to not exceed the preset threshold.

[0108] The first preset threshold can also be a range of pressure values ​​near the target pressure information. In this case, if a pressure difference exists and the historical pressure information exceeds the range of the first preset threshold, the comparison result is determined to exceed the preset threshold; conversely, if a pressure difference does not exist or a pressure difference exists but the historical pressure information is within the range of the first preset threshold, the comparison result is determined to not exceed the preset threshold.

[0109] Similarly, a second preset threshold can be set to judge changes in flow rate. The judgment process is similar to that described above and will not be repeated here.

[0110] Reference Figure 9 Since the first moving part 33 controls the flow of water, it must be opened every time water is sprayed. Therefore, before adjusting the first moving part 33 and / or the second moving part 37, the following steps are required:

[0111] Step S400: Detect whether the first moving part 33 is open;

[0112] Step S410: If not, control the first moving part 33 to open.

[0113] In the above steps, the first moving part 33 can be directly controlled to open to the historical position based on the historical position information, and then adjustments can be made.

[0114] Understandably, when the comparison result does not exceed the preset threshold, the first moving part 33 and the second moving part 37 can be kept in their historical positions. When the comparison result exceeds the preset threshold, depending on the actual situation, the first moving part 33 and the second moving part 37 can be adjusted simultaneously, or only one of them can be adjusted.

[0115] Specifically, target location information is generated based on the comparison results and corresponding historical location information. This target location information includes first target location information and second target location information. Understandably, the positions of the first moving part 33 and the second moving part 37 correspond to the changing trends of water pressure, flow rate, and velocity.

[0116] Reference Figure 4 , Figure 5 and Figure 6 In one embodiment, the historical information includes historical pressure information and historical flow rate information, the preset information includes target pressure information and target flow rate information, and the comparison result includes a first difference between historical pressure information and target pressure information and a second difference between historical flow rate information and target flow rate information.

[0117] Based on the comparison results, the steps for generating target location information include:

[0118] S331: Generate the first target location information based on the first difference;

[0119] and / or

[0120] S332: Generate the second target location information based on the second difference;

[0121] The first target position information is used to control the movement of the first moving part 33, and the second target position information is used to control the movement of the second moving part 37.

[0122] As described in the previous embodiment, the first difference is the pressure difference, the second difference is the flow rate difference, and the motion control of the first moving part 33 is mainly based on the first difference, and the motion control of the second moving part 37 is mainly based on the second difference.

[0123] Taking the first difference as the target pressure information minus the historical pressure information as an example, when the first difference is positive and greater than the upper limit of the first preset threshold, it indicates that the pressure is too low and needs to be increased; when the first difference is negative and less than the lower limit of the first preset threshold, it indicates that the pressure is too high and needs to be decreased. In this embodiment, when the flow channel 10a extends horizontally, the first moving part 33 is located above the flow channel 10a and can enter the flow channel 10a radially. It can be understood that by making the portion of the first moving part 33 extending into the flow channel 10a longer, the opening between the first moving part 33 and the wall of the flow channel 10a becomes smaller, and the water pressure at the outlet decreases; conversely, the water pressure increases.

[0124] Similarly, taking the second difference as the target flow rate information minus the historical flow rate information as an example, when the second difference is positive and greater than the upper limit of the second preset threshold, it indicates that the flow rate is too low and needs to be increased; when the second difference is negative and less than the lower limit of the second preset threshold, it indicates that the flow rate is too high and needs to be decreased. In this embodiment, the second moving part 37 is set close to the water inlet end of the flow channel 10a. When the second moving part 37 is close to the first moving part 33, the flow rate increases, and vice versa. This adjusts the opening between the first moving part 33 and the wall of the flow channel 10a to become smaller, and the water pressure at the outlet end becomes smaller, and vice versa.

[0125] Based on the above rules, the first target position information and the second target position information that meet the requirements can be generated according to the first difference, the second difference and the historical position information, respectively. This information can be used as the basis for controlling the movement of the first moving part 33 and the second moving part 37 to maintain the stability of the water flow.

[0126] Optionally, when both the first moving part 33 and the second moving part 37 are electromagnetically controlled, the target position information corresponds to the electromagnetic pulse signal. Taking the first moving part 33 as an example, the longer the pulse signal duration or the wider the pulse signal, the longer the length of the first moving part 33 extends into the flow channel 10a, and the closer its position is to the wall of the flow channel 10a on the other side. That is to say, the first target position information and the second target position information can be specifically represented on the pulse waveform of the input electrical signal.

[0127] Understandably, the generated target location information will be stored and used as historical location information for the next water spray control.

[0128] Reference Figure 7 In one embodiment, the step of obtaining historical information of the outlet end of the flow channel 10a includes:

[0129] S110: Obtain historical flow rate and velocity information at the outlet end of flow channel 10a;

[0130] S120: Generate historical pressure information based on historical flow rate information.

[0131] In this embodiment, historical pressure information can be obtained through the historical flow rate and velocity information and the water spray pressure model algorithm. That is, the flow rate and velocity detection module is only set at the outlet end of the flow channel 10a. When multiple water spray mechanisms 200 are equipped with sensors, the cost is low.

[0132] Optionally, when comparing the results, pressure information and flow rate information can be compared simultaneously.

[0133] It can also be, for reference Figure 8 In one embodiment, the step of comparing historical information with preset information to obtain the comparison result includes:

[0134] S210: Compare historical pressure information with target pressure information to obtain the first difference;

[0135] S220: Based on the first difference, obtain the second difference.

[0136] In this embodiment, historical pressure information is directly acquired and then compared. The first difference obtained from the comparison is used by the flow rate algorithm module to generate a second difference. The flow rate algorithm module reflects the correspondence between flow rate and pressure, and thus the second difference can also be obtained from the acquired pressure information.

[0137] Understandably, this application does not restrict the detection module at the outlet end of flow channel 10a. Only a flow rate / velocity detection module or a pressure detection module may be provided, and historical information and comparison results can be obtained using methods similar to those described above. Alternatively, both modules can be set simultaneously, resulting in direct, rapid, and highly efficient information acquisition.

[0138] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
