Description

[Technical Field]

[0001] The present invention relates to a vibration motor with a cleaning nozzle, and more particularly, to a vibration motor with a cleaning nozzle that simplifies the internal structure by installing the cleaning nozzle in the empty space inside the motor housing, thereby improving noise during vibration, reducing manufacturing costs, ensuring economy, and increasing productivity. Furthermore, the present invention relates to a vibration motor with a cleaning nozzle that can efficiently clean objects by supplying various cleaning solvents such as water, oil, powder, and air to the cleaning nozzle. [Background technology]

[0002] Generally, a bidet is installed in a toilet to clean the anus and private parts of the human body. Its cleaning functions include anal cleansing, which cleans the anus without toilet paper after using the toilet with cleaning water sprayed from a nozzle, private parts cleansing, which cleans the female private parts with the same cleaning water, and massage cleansing, which achieves a massage effect by repeatedly moving the nozzle spraying the cleaning water back and forth.

[0003] However, the nozzles provided for the above-mentioned cleaning have the problem that the cleaning water discharged from the cleaning water tank in the bidet is sprayed straight through the cleaning hole, making it difficult to effectively cleanse the area to be cleaned.

[0004] To solve this problem, a spray tip structure for a bidet nozzle was registered in Korean Utility Model No. 20-0411530.

[0005] However, the structure of the spray tip of the registered bidet nozzle described above sprays out cleansing water by repeatedly opening and closing the cleaning hole while rotating the rotating member using cleansing water supplied from the bidet tank. This reduces the amount of cleansing water consumed and increases cleaning efficiency, but the cleansing water is sprayed out in constant, intermittent amounts, which not only causes pain due to the water pressure of the cleansing water but also gives the user a sense of strangeness.

[0006] Recently, to solve this problem, a vibrating device for a bidet nozzle was registered in Korean Utility Model Publication No. 20-0422546.

[0007] However, the above-mentioned bidet nozzle vibration device has a vibration unit built into the nozzle with a flow path formed, and the vibration member rotates in response to a bidet button signal to vibrate the nozzle and spray cleansing water. This has the advantage of widening the cleaning area and making cleaning easier, but because the vibration unit is integrally attached to the inside of the nozzle, the nozzle vibration amplitude is small and cleaning power is poor. In addition, the vibration member that vibrates the nozzle is attached perpendicular to the nozzle pipe or in a vertical direction, so there is a limit to giving active action to the water spraying through the cleaning hole.

[0009] Therefore, the present invention has been made in consideration of the above-mentioned conventional problems, and its purpose is to provide a vibration motor with a cleaning nozzle that simplifies the internal structure by attaching the cleaning nozzle to the empty space inside the motor housing, thereby not only improving the noise phenomenon during vibration but also reducing manufacturing costs, ensuring economy, and increasing productivity.

[0010] Another object of the present invention is to provide a vibration motor with a cleaning nozzle that can efficiently clean an object by supplying various cleaning solvents such as water, oil, powder, and air to the cleaning nozzle. [Means for solving the problem]

[0021] The present invention will be described in detail below with reference to the accompanying drawings, in which: Fig. 1 is a perspective view of a vibration motor with a cleaning nozzle according to an embodiment of the present invention; and Fig. 2 is an exploded perspective view of the vibration motor with a cleaning nozzle according to an embodiment of the present invention.

[0022] First, a vibration motor 100 with a cleaning nozzle according to an embodiment of the present invention includes a motor housing 110, a cleaning nozzle 120 mounted in the center of the interior of the motor housing 110 and rotated by a vibration unit 150 to supply cleaning solvent to a water inlet 123 and clean an object with the cleaning solvent diffusing at a certain angle, front and rear covers 140, 140' coupled to the front and rear of the motor housing 110, and a vibration unit 150 coupled to both sides of the cleaning nozzle 120 inside the motor housing 110 to rotate the cleaning nozzle 120 forward and backward and vibrate it.

[0023] As shown in FIGS. 3 to 5, the motor housing 110 has a body portion 111 having a through hole 111a at the top so that the cleaning solvent can be sprayed, and a mounting hole 112 provided at the center of the inside of the body portion 111 to mount a cleaning nozzle 120.

[0024] The mounting hole 112 is a space in which the cleaning nozzle 120 is mounted, and also a space in which the cleaning nozzle 120 rotates forward and backward.

[0025] The body 111 has coupling spaces 113 formed inside both sides thereof to which the vibrating unit 150 is coupled, and the front end of the body 111 is open to accommodate the coupling spaces 113 .

[0026] Rotation spaces 114 are provided on both sides of the rear end of the body 111, one of which faces downward around the center and the other of which faces upward around the center, allowing the cleaning nozzle 120 to rotate forward and backward.

[0027] Fixing pieces 114 are formed on both sides of the rear end of the body 111, and fixing holes 114a are formed in the fixing pieces 114 so that a rear cover 140' can be attached thereto.

[0028] The cleaning nozzle 120 includes a nozzle body 121 that is mounted in the mounting hole 112 of the motor housing 110. The nozzle body 121 is formed in two separate parts, namely, first and second bodies 121a and 121b, which are combined to complete the nozzle body 121.

[0029] The nozzle body 121 is provided at one side with a water inlet 122 into which a cleaning solvent flows, and the nozzle body 121 is provided with a rotation shaft 123 so that the cleaning nozzle 120 rotates within the motor housing 110 .

[0030] The water inlet 122 may be provided only once at the center of one side of the nozzle body 121, and the water inlet 122 may be configured such that a first water inlet 122a is provided at an upper part of one side of the nozzle body 121 to allow the cleaning solvent to flow in, and a second water inlet 122b is provided at a lower part of one side of the nozzle body 121 to allow the cleaning solvent to flow in.

[0031] Therefore, the first flow path formed in the first water inlet 122a is for strong cleaning, and the second flow path formed in the second water inlet 122b is for gentle cleaning, and the shape, diameter, and number of the first and second flow paths can be changed as appropriate depending on the object.

[0032] As shown in Figures 6 and 7, a bearing 124 may be installed in a single water inlet 122 provided in the center of one side of the nozzle body 121, and a rotation shaft 123 is installed in the nozzle body 121 on the other side of the bearing 124. The bearing 124 is installed inside a rear cover 140' fixed to the rear end of the motor housing 110, thereby guiding the rotation of the cleaning nozzle 120 stably and quietly.

[0033] In addition, the front cover 140 is closed to prevent water from penetrating into the vibrating part 150 mounted inside the motor housing 110, thereby preventing corrosion, and is fixed by ultrasonic welding or an insert molding method.

[0034] The rear cover 140 ′ has fixing protrusions 141 protruding from both sides thereof, and is fixed to fixing holes 114 a of fixing pieces 114 provided at the rear end of the motor housing 110 .

[0035] The vibrating part 150 is composed of a stator 151, an insulator 152, a coil 153 and a magnet 154, and the stator 151 is installed in each of the coupling spaces 113 provided on both sides inside the body part 111.

[0036] Insulators 152 are coupled to the front and rear ends of the stator 151 and are fixed inside the motor housing 110 .

[0037] Here, the stator 151 and the insulator 152 are integrally formed by insert injection, and a coil 153 is wound around the stator 151 .

[0038] Magnets 154 are fixed to both sides of the first and second bodies 121a and 121b of the cleaning nozzle 120. Therefore, by operating the vibration unit 150 configured as described above, the cleaning nozzle 120 rotates forward and backward around the rotation axis 123, generating vibrations.

[0039] When the cleaning nozzle 120 vibrates, the cleaning solvent supplied through the water inlet 122 is sprayed into the nozzle holes while spreading over a wider range, thereby improving cleaning efficiency.

[0040] When the vibration unit 150 is operated, the cleaning nozzle 120 generates vibrations while rotating forward and backward around the rotation shaft 123. At this time, the motor housing 110 does not rotate, and only the cleaning nozzle 120 rotates. This eliminates the weight of the metal rotation shaft, the weight of the permanent magnet fixing part, and the weight of the shaft and connecting member, which are required in existing vibration motors, thereby significantly reducing noise during vibration, simplifying the vibration motor structure, and reducing manufacturing costs, thereby ensuring economy and improving productivity.

[0041] Here, the cleaning solvent includes water, oil, various powders, and compressed air.

[0042] That is, among cleaning solvents, water can be supplied to the water inlet 122 or the first and second water inlets 122a and 122b of the cleaning nozzle 120 and vibration-sprayed to be applicable to a bidet nozzle or a dishwasher nozzle, etc., while alcohol, thinner, volatile oil, etc. can be vibration-sprayed to efficiently remove oil stains, and powders such as glass or sand can be vibration-sprayed to clean the surface of corroded iron plates, and compressed air can be sprayed when entering or exiting a clean or dust-proof area to efficiently remove foreign matter or dust adhering to clothing or skin.

[0043] As described above, the present invention has been described using limited embodiments and drawings. However, the terms and words used in this specification and claims should not be interpreted in a limited manner based on their ordinary or dictionary meanings, but should be interpreted in a manner consistent with the technical ideas of the present invention.

[0044] Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely one embodiment of the present invention and do not represent the entire technical idea of the present invention, so it should be understood that various equivalents and modifications may exist without departing from the scope of the claims of the present invention.
