DETAILED DESCRIPTION

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the present invention.

[0022] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0023] The purpose of the present invention is to overcome the shortcomings of shower heads in the background technology and provide a new type of shower head. When people take a bath, the water spray coverage area of ​​the shower head can be adjusted to adapt to people's bathing methods in different situations, making the bathing device more convenient and more humane.

[0024] An adjustable shower head of the present invention has a preferred embodiment as shown in the accompanying drawings.

[0025] An adjustable shower head comprises a shower head body, an auxiliary shower head and an adjusting device.

[0026] The main body of the nozzle body is basically the same as the prior art, including a bend 1, an upper bottom surface 2, a first sleeve 8, a water outlet 11, a pipe joint 12, a lower bottom surface 13 and a second sleeve 81. The nozzle body is in the shape of a flat box, and the upper part of the upper bottom surface 2 of the flat box has a center hole, and the center hole is connected to the bend 1 of the water supply system through the pipe joint 12. The water outlet holes 11 are evenly distributed on the lower bottom surface 13 of the flat box. In order to fix the adjustment device inside the nozzle body, the first sleeve 8 and the second sleeve 81 with axes parallel to each other and staggered to each other are fixed on the left and two side surfaces of the nozzle body. The internal center holes of the first sleeve 8 and the second sleeve 81 are communicated with the outside of the nozzle body.

[0027] The auxiliary nozzle is an extended and movable water spraying part of the device, including a left half ring 3, a right half ring 31, an auxiliary water outlet hole 14, a first water inlet pipe 7, and a second water inlet pipe 71. The left half ring 3 and the right half ring 31 are both hollow semicircular rings with rectangular cross-sections. The bottom of the semicircular ring has evenly distributed auxiliary water outlet holes 14. The auxiliary water outlet holes 14 can be one row or several rows, depending on the needs. The left half ring 3 and the right half ring 31 surround the side surface of the outside of the nozzle body, which can reduce the space occupied by the shower nozzle. The middle part of the inner side of the left half ring 3 is connected to the first water inlet pipe 7, which passes through the circular hole inside the first sleeve 8 to enter the interior of the nozzle body and is connected to the components of the adjustment device. The middle part of the inner side of the right half ring 31 is connected to the second water inlet pipe 71, which passes through the circular hole inside the second sleeve 81 to enter the interior of the nozzle body and is connected to the components of the adjustment device.

[0028] The adjusting device is a key device for achieving the purpose of the present invention. In order to facilitate the adjustment and simplify the adjustment process, the water baffle 4, the first trapezoidal head 5, the first straight rod 6, the cylindrical gear 9, the pin 10, the second trapezoidal head 51, and the second straight rod 61 are designed according to the mechanical transmission principle.

[0029] The pin 10 is vertically fixed at the central position of the lower bottom surface 13 of the nozzle body, and a cylindrical gear 9 is installed on the pin 10, and the cylindrical gear 9 can rotate freely on the pin 10. The left part of the adjustment device includes a first straight rod 6 with a rectangular cross-section, which is welded to the right end of the first water inlet pipe 7 perpendicular to the lower bottom surface 13, and a semicircular water inlet is left at the mouth of the first water inlet pipe 7. A rack is made on the side of the first straight rod 6, and the rack is meshed with the cylindrical gear 9. The right end of the first straight rod 6 is connected to the first trapezoidal head 5, and the bottom surface of the first trapezoidal head 5 is in contact with the lower bottom surface 13 of the nozzle body. The bottom surface of the first trapezoidal head 5 is in contact with the lower bottom surface 13 of the nozzle body to prevent the auxiliary nozzle from rotating, and can only move parallel to the axial direction.

[0030] The right side portion of the regulating device has the same structure as the left side portion and their positions correspond to each other.

[0031] The water baffle 4 is a rectangular plate. The two water baffles 4 are respectively attached to the first straight rod 6 and the second straight rod 61 and fixed on the lower bottom surface 13. When the left half ring 3 or the right half ring 31 is pulled outward to leave the nozzle body, the racks on the first straight rod 6 and the second straight rod 61 drive the cylindrical gear 9 to rotate counterclockwise, and the semicircular water inlets of the first water inlet pipe 7 and the second water inlet pipe 71 leave the water baffle 4. The bathing water enters the interior of the nozzle body from the bent pipe 1 and is sprayed out from the water outlet 11. A part of it flows into the nozzle body. The bathing water enters the left half ring 3 and the right half ring 31 respectively along the water inlets of the first water inlet pipe 7 and the second water inlet pipe 71, and is sprayed out from the auxiliary water outlet hole 14; when the left half ring 3 or the right half ring 31 is pushed inward to fit the nozzle body, the racks on the first straight rod 6 and the second straight rod 61 drive the cylindrical gear 9 to rotate clockwise, and the semicircular water inlets of the first water inlet pipe 7 and the second water inlet pipe 71 contact the water baffle 4, blocking the bathing water flowing into the nozzle body from flowing into the left half ring 3 and the right half ring 31.

[0032] The function of the water baffle 4 is, first, that the auxiliary nozzle can be closed when it is connected to the water inlet of the first water inlet pipe 7 and the second water inlet pipe 71, so that only the nozzle body is working in spraying water, which has the same function as the existing shower nozzle and is suitable for single person bathing; second, the water baffle 4 is respectively attached to the first straight rod 6 and the second straight rod 61 and fixed on the lower bottom surface 13, so that the first straight rod 6 and the second straight rod 61 can be smoothly engaged with the cylindrical gear 9 without shaking, and the operation is reliable.

[0033] The first trapezoidal head 5 and the second trapezoidal head 51 fit with the lower bottom surface 13 of the nozzle body to further prevent the auxiliary nozzle from rotating, and when the auxiliary nozzle and the nozzle body are separated to the farthest distance, the connection with the cylinder 9 plays a limiting role.

[0034] In order to prevent water leakage, a heat-resistant sealing pad is pasted on the plane where the water baffle 4 contacts the semicircular water inlets of the first water inlet pipe 7 and the second water inlet pipe 71, and a heat-resistant sealing ring is attached to the connection between the first water inlet pipe 7, the second water inlet pipe 71 and the first sleeve 8, the second sleeve 81.

[0035] When in use, one side of the auxiliary nozzle can be directly pulled out by hand. According to the mechanical transmission principle, the rotation of the cylindrical gear 9 will bring the other side of the auxiliary nozzle out to an equal distance. The auxiliary nozzles on both sides move symmetrically outward or inward, and the pulling distance can be selected according to actual needs. When the auxiliary nozzle is not used, the auxiliary nozzle is directly pushed back inward. Inside the nozzle body, the water baffle 4 closes the auxiliary nozzle, leaving only the nozzle body to continue working.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered within the protection scope of the present invention.
