By adding a permanent magnet assembly and an electromagnetic coil assembly, the electromagnetic coil assembly, when energized, drives the permanent magnet assembly to oscillate, which in turn drives the nozzle assembly mounted on the permanent magnet assembly to oscillate synchronously. This solves the technical problem of existing spray nozzles having fixed nozzle seats and lacking oscillating water spray. The coordinated design of the permanent magnet assembly and nozzle assembly creates an oscillating effect during the water spray process, increasing the cleaning range and enabling the nozzle assembly to perform a reciprocating oscillation massage cleaning function, thus improving the user experience.

When the electromagnetic coil assembly is energized, it drives the permanent magnet assembly to oscillate, and the permanent magnet assembly drives the nozzle assembly to oscillate, thereby realizing the water spraying and cleaning function with oscillation.

[0005] The permanent magnet assembly and the electromagnetic coil assembly are arranged adjacent to each other without contact. The permanent magnet assembly is driven by the electromagnetic coil assembly at different frequencies to move with different swing amplitudes, thereby achieving different swing spray effects.

[0006] The water inlet assembly is provided with a mounting groove, and one end of the electromagnetic coil assembly is fixed to the mounting groove; the permanent magnet assembly is located above the electromagnetic coil assembly, and there is a gap between the two. The permanent magnet assembly is provided with an assembly groove for mounting the nozzle assembly, and the assembly groove passes through the outer shell of the permanent magnet assembly.

[0007] The body wash spray device also includes a valve body with a water spray channel. The water inlet assembly, the water spray channel and the nozzle assembly are connected in sequence so that the liquid enters the nozzle assembly through the water inlet assembly and the water spray channel in sequence. The lower part of the permanent magnet assembly is rotatably connected to the valve body.

[0008] The valve body includes a valve seat with a first connecting end and a second connecting end at the lower part of the permanent magnet assembly.

[0010] The bottom of the valve seat is provided with a sealing groove, and the upper part of the base is provided with a sealing rib. The sealing rib is inserted into the sealing groove so that the valve seat and the base are sealed and connected.

[0011] The water inlet assembly is equipped with a buckle, and the base is equipped with a fastening hole. When the water inlet assembly is connected to the valve body, the buckle and the fastening hole fasten together.

[0012] The valve seat is provided with limiting grooves for both single-hole and multi-hole spray columns.

The power supply is driven by a MOSFET, and the MOSFET is controlled by the I / O pins of a microcontroller, thereby controlling the power supply to the electromagnetic coil assembly. The microcontroller's I / O pins use PWM control.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In order to make the above-mentioned objects, features and advantages of this application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] See Figures 1-17A body-washing spray device with oscillating water spray includes a water inlet assembly 1 and a nozzle assembly 2, as well as a permanent magnet assembly 3 and an electromagnetic coil assembly 4. The nozzle assembly 2 is mounted on the permanent magnet assembly 3 and connected to the water inlet assembly 1. The permanent magnet assembly 3 is oscillatingly mounted on the body-washing spray device. The electromagnetic coil assembly 4 is electrically connected to a control device. When the electromagnetic coil assembly 4 is energized, it drives the permanent magnet assembly 3 to oscillate, and the permanent magnet assembly 3 drives the nozzle assembly 2 to oscillate, thereby realizing the water spraying and cleaning function with oscillation.

[0037] By adding a permanent magnet assembly 3 and an electromagnetic coil assembly 4, the electromagnetic coil assembly 4, when energized, drives the permanent magnet assembly 3 to oscillate, which in turn drives the nozzle assembly 2 mounted on the permanent magnet assembly 3 to oscillate synchronously. This solves the technical problem of existing spray nozzles having fixed nozzle seats and lacking oscillation amplitude for water spraying. The coordinated design of the permanent magnet assembly 3 and the nozzle assembly 2 creates an oscillation effect during water spraying, increasing the range of water spray cleaning and enabling the nozzle assembly 2 to perform reciprocating oscillation massage cleaning, thus improving the user experience.

[0038] The nozzle of the personal hygiene spray device is installed inside the spray bar 6.

[0039] The permanent magnet assembly 3 and the electromagnetic coil assembly 4 are arranged adjacent to each other without contact. The permanent magnet assembly 3 is driven by the electromagnetic coil assembly 4 at different frequencies to move with different swing amplitudes, thereby achieving different swing spray effects.

[0040] The permanent magnet assembly 3 and the electromagnetic coil assembly 4 are arranged in a non-contact, adjacent manner, allowing for smoother oscillation. By driving the electromagnetic coil assembly 4 at different frequencies, the oscillation amplitude of the permanent magnet assembly 3 can be flexibly adjusted, thereby achieving oscillation water spray with different widths, improving the versatility and practicality of the device, and enhancing the user experience. The water inlet assembly 1 is provided with an installation groove 101, and one end of the electromagnetic coil assembly 4 is fixed on the installation groove 101; the permanent magnet assembly 3 is located above the electromagnetic coil assembly 4, and there is a gap between the two. The permanent magnet assembly 3 is provided with an assembly groove 302 for mounting the nozzle assembly 2, and the assembly groove 302 passes through the outer shell of the permanent magnet assembly 3.

[0041] The permanent magnet assembly 3 includes a housing and a permanent magnet encapsulated within the housing. When the adjacent electromagnetic coil assembly 4 is energized, it generates a changing magnetic field. This magnetic field interacts with the permanent magnetic field inherent in the permanent magnet assembly, producing a thrust or pull force, thereby driving the permanent magnet assembly (and the nozzle mounted on it) to oscillate back and forth. Permanent magnets (or permanent magnet bodies) are made of hard magnetic materials such as iron, neodymium, and samarium cobalt. Once magnetized, their magnetism does not disappear under normal conditions.

[0042] The mounting groove 101 of the water inlet assembly 1 provides a stable mounting base for the electromagnetic coil assembly 4, ensuring that the electromagnetic coil assembly 4 is fixed in position. The permanent magnet assembly 3 is located above the electromagnetic coil assembly 4 and is spaced apart, which ensures the effective function of electromagnetic drive while avoiding contact between the two, thus preventing interference between the electromagnetic coil assembly 4 and the permanent magnet assembly 3 and affecting the swing of the permanent magnet assembly 3. The assembly groove 302 of the permanent magnet assembly 3 penetrates the outer shell, facilitating the installation of the nozzle assembly 2. The body-washing water device also includes a valve body 5, which is provided with a water spray channel 501. The water inlet assembly 1, the water spray channel 501 and the nozzle assembly 2 are connected in sequence so that the liquid enters the nozzle assembly 2 through the water inlet assembly 1 and the water spray channel 501 in sequence. The lower part of the permanent magnet assembly 3 is rotatably connected to the valve body 5.

[0043] The water spray channel 501 of the valve body 5 provides a dedicated channel for liquid flow, enabling the water inlet assembly 1, the water spray channel 501, and the nozzle assembly 2 to form a complete water supply path, ensuring liquid delivery. The lower part of the permanent magnet assembly 3 is rotatably connected to the valve body 5, providing stable support for the swing of the permanent magnet assembly 3. At the same time, the structure of the valve body 5 provides a mounting carrier for various components, realizing the functional integration of components such as the water inlet assembly 1, the permanent magnet assembly 3, and the electromagnetic coil assembly 4, making the device structure more compact and space utilization more efficient. The valve body 5 includes a valve seat 502, a first connecting end 5021 on the valve seat 502, a second connecting end 301 at the lower part of the permanent magnet assembly 3, a connecting shaft 6 between the first connecting end 5021 and the second connecting end 301, the valve seat 502 and the permanent magnet assembly 3 are oscillatingly connected by the connecting shaft 6, and a gap is provided between the valve seat 502 and the left and right sides of the permanent magnet assembly 3 for the permanent magnet assembly 3 to oscillate.

[0044] The first connecting end 5021 of the valve seat 502 and the second connecting end 301 of the permanent magnet assembly 3 are oscillatingly connected through the connecting shaft 6. The gaps reserved on the left and right sides of the valve seat 502 and the permanent magnet assembly 3 provide sufficient space for the permanent magnet assembly 3 to oscillate, and the permanent magnet assembly 3 is limited to oscillation within the valve seat 502. The valve body 5 also includes a base 503 that is sealed and connected to the valve seat 502, and the water spray channel 501 is disposed between the valve seat 502 and the base 503; The water spray channel 501 includes a first channel 5011 and a second channel 5012 that are not interconnected; the valve seat 502 is provided with a first connector 5022 and a second connector 5023; the water inlet assembly 1 includes a first water inlet connection end 102 and a second water inlet connection end 103; the nozzle assembly 2 includes a single-hole spray column 201 and a multi-hole spray column 202 installed on the permanent magnet assembly 3. The first water inlet connection 102, the first connector 5022, the first flow channel 5011 and the single-hole spray column 201 are connected in sequence. The second water inlet connection 103, the second connector 5023, the second flow channel 5012 and the multi-hole spray column 202 are connected in sequence.

[0045] The valve seat 502 of the valve body 5 is sealed to the base 503, forming a closed space in the water spray channel 501 to prevent water leakage. The first channel 5011 and the second channel 5012 of the water spray channel 501 are not interconnected. Combined with the connection paths between the first water inlet connection 102, the first connector 5022 and the single-hole spray column 201, and the second water inlet connection 103, the second connector 5023 and the multi-hole spray column 202, independent control of single-hole and multi-hole spray modes is achieved. Users can switch between different spray columns as needed. The single-hole spray column 201 is suitable for concentrated cleaning, while the multi-hole spray column 202 is suitable for wide-range gentle cleaning, enriching the cleaning functions, improving the device's adaptability, and the dual-channel design avoids water flow interference between different spray modes, ensuring the stability of water output in each mode. The first connector 5022 and the second connector 5023 are respectively inserted into the water inlet assembly 1.

[0046] The bottom of the valve seat 502 is provided with a sealing groove 5024, and the upper part of the base 503 is provided with a sealing rib 5031. The sealing rib 5031 is inserted into the sealing groove 5024 so that the valve seat 502 and the base 503 are sealed and connected.

[0047] The sealing groove 5024 at the bottom of the valve seat 502 and the sealing rib 5031 on the upper part of the base 503 cooperate to form a precise sealing structure, effectively enhancing the sealing performance of the valve seat 502 and the base 503 and preventing liquid leakage in the water spray channel 501. The design of the sealing rib 5031 inserting into the sealing groove 5024 makes the sealing contact tighter, and at the same time, it can be quickly positioned during assembly, improving the assembly efficiency of the valve seat 502 and the base 503. Moreover, the sealing structure is simple and reliable, requiring no additional sealing components, reducing assembly complexity and cost. After the valve seat 502 and the base 503 are assembled, the installation gap between them can be sealed by laser welding. The water inlet assembly 1 is provided with a buckle 104, and the base 503 is provided with a fastening hole 5033. When the water inlet assembly 1 is connected to the valve body 5, the buckle 104 and the fastening hole 5033 are fastened together.

[0048] The buckle 104 of the water inlet component 1 and the snap-fit ​​hole 5033 of the base 503 are connected by a snap-fit ​​method, so that the assembly of the water inlet component 1 and the valve body 5 does not require tools, making the operation convenient and efficient, and the installation can be completed quickly. The valve seat 502 is provided with limiting grooves 5024 corresponding to both the single-hole spray column 201 and the multi-hole spray column 202. The lower part of the single-hole spray column 201 and the multi-hole spray column 202 are limited on the corresponding limiting grooves 5024, and the lower part of the spray column is in clearance fit with the limiting grooves 5024.

[0049] The limiting groove 5024 on the valve seat 502 limits the lower part of the single-hole spray column 201 and the multi-hole spray column 202, ensuring the accurate installation position of the spray column. The clearance fit between the lower part of the spray column and the limiting groove 5024 does not affect the permanent magnet assembly 3 from driving the spray column to swing, and also provides support for the spray column.

[0050] The water spray channel 501 is provided with a water-blocking rib 5032 for blocking the water flow to change the direction of the water flow channel and realize the water outlet shape. The water-blocking rib 5032 is correspondingly set with the water inlet end of the nozzle assembly 2. The water-blocking rib 5032 is installed on the base 503 of the valve body 5.

[0051] The water-retaining rib 5032 is integrated into the base 503, featuring a compact structure that does not occupy additional space. Its simple design eliminates the need for complex processing, reducing production costs. Simultaneously, the water-retaining rib 5032 guides water flow into the nozzle assembly 2.

[0052] The electromagnetic coil assembly 4 includes a housing and a vibrating nozzle coil disposed inside the housing. The housing has a wire outlet hole, and the coil is connected to the lead wire. The sheath of the lead wire and the wire outlet hole can be fitted with glue or interference seal.

[0053] A control method for a body-washing spray device with swing spray as described above, wherein the control device includes a microcontroller, a MOSFET, a DC power supply chip LDO, and a power supply mounted on a control circuit board; The microcontroller, MOSFET, LDO DC power supply chip, power supply, and electromagnetic coil assembly 4 are electrically connected to the control circuit board respectively. Its control method includes the following steps: The power supply voltage is converted into the voltage required for the operation of the electromagnetic coil assembly 4 by the DC power chip LDO. The power supply is driven by a MOSFET, and the MOSFET is controlled by the I / O pins of a microcontroller, thereby controlling the power supply to the electromagnetic coil assembly 4. The microcontroller's IO pins use PWM control. The oscillation amplitude of the vibrating nozzle is controlled by adjusting the duty cycle of the PWM signal, and the vibration oscillation frequency of the permanent magnet assembly 3 is controlled by adjusting the period T of the PWM signal, thereby realizing the reciprocating oscillation massage cleaning of the nozzle assembly 2.

[0054] The control method for the body-washing water spray device with swing spray also includes a microcontroller timer. The microcontroller timer is electrically connected to the control circuit board. The timer counts to accurately calculate the time period of setting the microcontroller's IO pins high and low, so as to precisely control the duty cycle and period of the PWM signal.

[0055] By adjusting the duty cycle and period of the PWM signal, the oscillation amplitude and oscillation frequency of the nozzle assembly 2 are controlled to achieve an adjustable massage and cleaning effect.

[0056] The vibrating nozzle coil is powered by 5V. The power supply voltage is converted into the working voltage of the vibrating nozzle coil (about 2V) by the DC power chip LDO, which provides a continuous power supply for the vibrating nozzle coil to turn on and off.

[0057] The 5V power supply is driven by a MOSFET 3400, and the MOSFET is controlled by a microcontroller's I / O pins, thereby controlling the on / off state of the power supply to the vibrating nozzle coil.

[0058] The microcontroller uses PWM pin V1 for control, enabling the vibrating nozzle to oscillate at different amplitudes to achieve a massage and cleaning effect.

[0059] The duty cycle is determined by dividing time T1 by the total working cycle T. The frequency of the vibration oscillation depends on the period T. A microcontroller's I / O pins control the MOSFET, and a timer is used to accurately calculate the high and low time periods of the pins, driving the vibrating nozzle coil to achieve the reciprocating oscillation massage and cleaning function of nozzle assembly 2.

[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
