Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bathroom, especially a novel self-generating nozzle. BACKGROUND

[0002] In order to meet the diversified needs, adding electronic components to the bathroom equipment to increase user experience is the development trend. Once the electronic components are added, power supply is needed. The traditional solution is to lead the power-on line into the power supply or set up a battery box to install a power supply battery. This traditional power supply method makes the installation and maintenance cost of the equipment high, and the user needs to bear certain electricity charges for the use of this nozzle. In order to solve the problem of installation and maintenance cost, reduce the user's use cost and improve the user experience, the applicant once proposed a patent named "a self-generating nozzle" with the application number "CN202011375956.1" on November 30, 2020. The patent discloses a self-generating nozzle, which includes a nozzle cover, a nozzle seat, a nozzle core and a nozzle core seat. The nozzle core is rotatably installed in the nozzle core seat. The nozzle core rotates relative to the nozzle core seat under the action of water jet. The nozzle core seat is fixedly installed in the nozzle seat. The nozzle cover cooperates with the nozzle seat to fix the novel self-generating nozzle on a wall. The characteristic is that the nozzle core is provided with an induction coil group connected with the external circuit. The nozzle core seat is provided with a magnet group corresponding to the induction coil group. When the nozzle core rotates relative to the nozzle core seat under the action of water jet, the nozzle core drives the induction coil group in the nozzle core to rotate relative to the magnet group in the nozzle core seat. The induction coil group moves in the magnetic field of the magnet group to generate induction current. The novel self-generating nozzle drives the nozzle core to rotate under the action of water jet to drive the induction coil group to rotate to generate induction current to generate electricity. However, in the subsequent use, the applicant found that because the induction coil group is installed together with the nozzle core, the weight of the nozzle core is large, and the pushing force required to push the nozzle core to rotate is also relatively high compared with the ordinary nozzle core. The power generation efficiency of the novel self-generating nozzle is naturally limited by the rotation speed of the nozzle core, and it is difficult to better control or output more induction current. In addition, because the induction coil group needs to be added in the nozzle core, the production, installation and maintenance of the nozzle core increase the cost, including mold cost, design cost, assembly cost and maintenance cost. Based on this, the applicant improves the above-mentioned scheme and proposes a novel self-generating nozzle. UTILITY MODEL CONTENTS

[0024] The novel self-power generation nozzle provided by the utility model will be further described below with reference to the drawings, and it should be pointed out that only the most optimized technical solution is used to elaborate the technical solution and design principle of the utility model in detail below.

[0025] With reference to Figure 1 , Figure 2 and Figure 8 , the novel self-power generation nozzle provided by the first embodiment of the utility model comprises a nozzle face cover 1, a nozzle core 2, a power generation core 3, a nozzle core seat 4 and a nozzle seat 5, wherein the nozzle core seat 4 is fixedly installed in the nozzle seat 5 through thread cooperation, the nozzle core 2 and the power generation core 3 are installed in the nozzle core seat 4, and the nozzle face cover 1 is installed on the nozzle seat 5 through buckle cooperation.

[0026] Then, with reference to Figure 2 , Figure 3 and Figure 8 , the power generation core 3 comprises a power generation core cover 31, a first electromagnetic induction component 32 and a second electromagnetic induction component 33, the power generation core cover 31 and the second electromagnetic induction component 33 are fixedly installed in the nozzle core seat 4, the first electromagnetic induction component 32 is rotatably installed between the power generation core cover 31 and the nozzle core seat 4, and the first electromagnetic induction component 32 is located in the hollow part of the second electromagnetic induction component 33, that is, the electromagnetic induction component 33 is arranged around the first electromagnetic induction component 32, and the power generation core generates an induced current by rotating relative to the second electromagnetic induction component 33 under the action of water flow injection based on the first electromagnetic induction component 32, and the induced current is output to the circuit board 6, thereby driving the LED lamp on the circuit board 6 to perform light emitting operation.

[0027] Among them, the light emitting surface of the LED lamp faces the direction of water flow injection, and the light emitted by the LED lamp is emitted along with the injected water flow, realizing a gorgeous light and water flow effect.

[0028] Then, continue to combine Figure 2 , Figure 3 andFigure 8 The nozzle core 2 is rotatably installed between the nozzle face cover 1 and the power generation core cover 31, and rotates relative to the nozzle core seat 4 under the action of water flow injection to output rotating water flow and complete water spraying work,

[0029] Secondly, the outer thread of the nozzle seat 5 is matched with a nut (not shown in the figure) to be clamped and fixedly installed on the wall body with holes, thereby installing the new self-powered nozzle on the wall body. In addition, the nozzle seat includes a water inlet and an air inlet. When the new self-powered nozzle is working, water flow enters the nozzle seat from the water inlet, cooperates with the air inlet, enters the water spraying channel, then passes through the power generation core 3, and then passes through the nozzle core 2 to spray out rotating water flow.

[0030] Among them, in combination with Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 8 , the first electromagnetic induction component 32 in the power generation core 3 includes a rotating shaft 321, a predetermined number of blades 322, and a magnet group 323. The magnet group 323 is distributed circumferentially around the rotating shaft 321. The predetermined number of blades 322 are arranged between the rotating shaft 321 and the magnet group 323. The blades 322, the magnet group 323, and the rotating shaft 321 are combined to form a rigid body through a first shell. Among them, the second electromagnetic induction component 33 includes an iron core shell 333, an iron core 331 installed in the iron core shell 333, and an induction coil 332 wound around the notch of the iron core. The notch of the iron core faces the first electromagnetic induction component 32. The iron core 331 attracts the magnetic induction lines of the magnet group 323. The iron core 331 is wound with a plurality of induction coils 332. When the first electromagnetic induction component 32 drives the entire first electromagnetic induction component 32 to rotate relative to the second electromagnetic induction component 33 under the action of water flow injection impacting the blades 322, the induction coil 332 cuts the magnetic induction lines between the magnet group 323 and the iron core 331 to generate an induced current, thereby realizing self-power generation of the nozzle.

[0031] Continuing to refer to Figure 8 Preferably, the magnet group 323 includes a predetermined number of N-pole magnets and S-pole magnets arranged alternately. The magnet group 323 generates a magnetic field. The alternately arranged magnets enhance the magnetic flux of the cutting area under the attraction of the iron core 311.

[0032] Preferably, referring to Figure 4 , Figure 6 and Figure 8 , the blade 322 of the first magnetic induction component 32 has a blade angle ranging from 15 to 30 degrees, and changing the blade angle can improve the water flow power conversion rate, accelerate the rotation speed of the first electromagnetic induction component 32, and increase the power generation capacity. The iron core shell 333 of the second magnetic induction component 33 is provided with a predetermined number of guide vanes 334 on the side of the water inlet direction, and the guide vanes 334 have a blade angle ranging from 15 to 30 degrees. Before the water flow jet pushes the first electromagnetic induction component 32, a vortex is formed through the guide vanes 334, increasing the subsequent water flow thrust on the blades 322 of the first electromagnetic induction component 32, which can further increase the power generation power.

[0033] Referring to Figure 3 and Figure 5 , in order to ensure the waterproof performance of the closed circuit between the circuit board 6 and the second electromagnetic induction component 33, the circuit board 6 is arranged in the iron core shell 333 by glue sealing, and the power generation core cover 31 is installed on the iron core shell 333 by spin fusion sealing, and double waterproof structure is adopted for waterproof.

[0034] Continuing to refer to Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 , both end faces of the power generation core cover 31 are provided with a rotating shaft seat, one end face of which is used to bear the rotating shaft of the nozzle core 2, and the other end face of which is used to bear the rotating shaft 321 of the first electromagnetic induction component 32. The iron core shell 333 is provided with a rotating shaft seat corresponding to the rotating shaft seat of the power generation core cover. The rotating shaft seat of one end face of the power generation core cover 31 cooperates with the rotating shaft seat of the nozzle face cover to realize the rotary support of the nozzle core, and the rotating shaft seat of the iron core shell 333 cooperates with the other end rotating shaft seat of the power generation core cover 31 to realize the rotary support of the first electromagnetic induction component. The double-face bearing design of the power generation core cover realizes the split design of the nozzle core and the power generation core.

[0035] Finally, in combination with Figure 5 and Figure 7 , in order to adapt the nozzle core seat 4 to install the power generation core 3, the iron core shell 333 of the power generation core 3 is provided with a positioning protrusion 336 and a buckle 335, and the nozzle core seat 4 is provided with a positioning hole and a clamping groove corresponding to the positioning protrusion 336 and the buckle 335. The positioning buckle and the clamping groove on the nozzle core seat 4 can be adjusted, which is not limited here.

[0036] It should be noted that the power generation core of the self-power generation nozzle is different from the power generation core structure of a common generator, and the power generation core structure of the common generator is magnetic pole-air gap-iron core, and since the power generation core of the self-power generation nozzle needs to be operated in water for a long time, the magnetic pole and the iron core need to be arranged in a sealed environment, and mechanical sealing cannot be achieved as the common generator, therefore, the shells of the first electromagnetic induction component and the second electromagnetic induction component are plastic thin walls, and the structure of the power generation core is magnetic pole-plastic thin wall of the first electromagnetic induction component-air gap-plastic thin wall of the second electromagnetic induction component-iron core, and in actual production, the plastic thin wall of the first electromagnetic induction component and the plastic thin wall of the second electromagnetic induction component should be designed to be thinner as much as possible to ensure the power generation efficiency of the power generation core.

[0037] The novel self-power generation nozzle provided by the utility model under the action of water flow injection, the power generation core generates induced current and outputs to the electric equipment, and after the water flow pushes the power generation core to generate electricity, the nozzle core is pushed to rotate to realize the output of rotating water flow and ensure the basic function of the nozzle, compared with the traditional novel self-power generation nozzle, the nozzle core and the power generation core are of a split type, the power generation efficiency of the power generation core is no longer limited by the rotating speed of the nozzle core, and therefore the power generation capacity can be more easily controlled and the power generation efficiency can be increased, meanwhile, the split type design makes the design of the nozzle core simpler, reduces the design cost, the split type assembly can also reduce the installation cost, reduces the maintenance cost in use, and the damaged parts can be replaced without the need of overall replacement.

[0038] The above is only the preferred embodiment of the utility model, and it should be noted that the above preferred embodiment should not be regarded as the limitation of the utility model, and the protection scope of the utility model should be limited by the scope defined by the claims. For ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the spirit and scope of the utility model, and these improvements and refinements should also be regarded as the protection scope of the utility model.
