Description

Technical Field

[0001] The present invention relates to the field of sanitary ware, and in particular to a spraying device, a method for realizing swing spraying, and a smart toilet. Background Art

[0002] At present, smart toilets (also known as smart toilet seats) on the market are generally divided into three types. One is a smart toilet with functions such as cleaning, heating, and sterilization. Another is a smart toilet that can automatically change the seat cover. The other is a smart toilet with both automatic seat cover changing and cleaning functions. Among them, the cleaning function of the smart toilet is the hip washing / feminine washing function. Specifically, a spraying device is provided on the smart toilet cover of the smart toilet, and the hip washing and feminine washing functions are realized by this spraying device. The spraying devices in the prior art generally include components such as a spraying body, a spray rod, a telescopic motor, a switching motor, and a water path switching member. The spray rod is telescopically arranged on the spraying body along a preset direction and is driven by the telescopic motor. The water path switching member and the switching motor cooperate to realize the switching of the water path of the spray rod. During operation, the spray rod extends, and the nozzle provided at its front end sprays hip washing water or feminine washing water upward. When not spraying water, the spray rod is driven by the telescopic motor to retract. In order to improve the comfort of the spraying device during spraying, some set the spray rod to be in a state of reciprocating movement back and forth, so that after the spray rod extends, it moves back and forth to achieve massage water flowers moving back and forth. Some also set a vibration motor in the nozzle assembly of the spray rod, and use the operation of the vibration motor to drive the nozzle assembly of the spray rod to vibrate, so that the cleaning water sprayed from the nozzle swings at least in the lateral direction, forming pulsating water in the lateral direction, thereby improving the rinsing experience. However, the method of generating lateral pulsed water by the vibration of the vibration motor has the following deficiencies: due to the long-term vibration of the vibration motor, the nozzle assembly of the spray rod is easily affected by the vibration and loosens, misaligns, etc., which affects the water tightness, connection firmness, etc. of the nozzle assembly, and further reduces the service life of the spray rod.

[0031] For the embodiment, please refer to Figures 1 - 10 As shown, a spraying and washing device of the present invention is used for hip washing and / or feminine washing, and includes a spraying and washing mechanism 1. The spraying and washing mechanism 1 includes a spraying and washing body 1 and a spray rod 12 that is telescopically arranged on the spraying and washing body 1 along a preset direction; it also includes a positioning seat 2 and a swing driving mechanism 3. The spraying and washing body 1 is rotatably arranged on the positioning seat 2 around the axis 121 of the spray rod and is connected to the swing driving mechanism 3, so as to be driven by the swing driving mechanism 3 to drive the spraying and washing mechanism 1 to rotate and swing around the axis 121 of the spray rod. The preset direction is specifically the front-back direction, the rotation and swing direction of the spraying and washing body 1 is in the left-right direction, and the rotation and swing angle of the spraying and washing body 1 on one side is approximately 0-5°, as Figure 7 shown.

[0032] In this embodiment, the swing driving mechanism 3 is arranged on the positioning seat 2. Specifically, the swing driving mechanism 3 includes a swing motor 31, a fixed seat 32, a swing arm 33 and a swing transmission structure. The fixed seat 32 is arranged on the positioning seat 2. The swing arm 33 is swingably arranged on the fixed seat 32 along the swing direction of the spraying and washing mechanism 1 and is connected to the spraying and washing body 1; the output shaft of the swing motor 31 is in transmission connection with the swing arm 33 through the swing transmission structure to drive the swing arm 33 to swing. The fixed seat 32 is vertical and is fixedly connected to the rear end of the positioning seat 2 by means of screw locking or insertion (the fixed position of the fixed seat 32 is not limited to the rear end of the positioning seat 2), but not limited thereto. In other embodiments, the fixed seat and the positioning seat are integrally formed.

[0033] In this embodiment, the swing drive structure includes a drive wheel 34 and a long hole 331 provided on the swing arm 33. The long hole 331 is located in the radial direction of the swing trajectory of the swing arm 33. The drive wheel 34 and / or the swing motor 31 are provided on the fixed seat 32, and the drive wheel 34 is driven by the swing motor 31. An eccentric part of the drive wheel 34 is provided with a drive shaft 341 (i.e., the axis of the drive shaft 341 is parallel to the axis of the drive wheel 34 but does not coincide). The drive shaft 341 is parallel to the output shaft of the swing motor 31, and the drive shaft 341 is inserted into the long hole 331. The diameter of the drive shaft 341 is slightly smaller than the width of the long hole 331.

The drive wheel 34 is fixedly sleeved on the output shaft of the swing motor 31. The drive wheel 34 is specifically a cam structure, but is not limited thereto. In other embodiments, the drive wheel is an eccentric wheel structure or a circular wheel structure.

[0034] In this embodiment, an angle limit structure 322 is provided on the fixed seat 32 to limit the angle of one-way or two-way rotation of the drive wheel 34. The angle limit structure 322 is specifically used to limit the angle of one-way rotation of the drive wheel 34, that is, Figure 3 in the perspective, the angle of counterclockwise rotation of the drive wheel 34. The angle of clockwise rotation of the drive wheel 34 is realized by the swing motor 31 through rotation angle setting and self-resetting. The setting of the angle limit structure 322 can ensure that the maximum angle of each counterclockwise and clockwise rotation of the drive wheel 34 remains unchanged, ensuring the stability and reliability of the overall operation. In other embodiments, the present invention does not provide the angle limit structure, and only realizes it by setting the rotation angle of the swing motor.

[0035] In this embodiment, the upper end of the fixed seat 32 is rotatably connected to a rotating shaft 35, the rotating shaft 35 can rotate around its axis, and the axis of the rotating shaft 35 is parallel to the axis of the output shaft of the swing motor 31, and the upper end of the swing arm 33 is connected to the rotating shaft 35.

The swing motor 31 is specifically a stepping motor, which is installed at the lower end of the fixing seat 32. By changing the position of the swing motor 31, the swing angle of the swing arm 33 can be adjusted. The long hole 331 is set at the lower end of the swing arm 33.

[0036] In this embodiment, the swing arm 33 is provided with a hanging portion 332, and the rear end of the spray cleaning body 1 is hung on the hanging portion 332. The hanging portion 332 is specifically located at the middle and lower part of the front side of the swing arm 33 and is higher than the long hole 331.

[0037] In this embodiment, the spray body 1 is provided with a shaft sleeve 111 coaxial with the spray rod 12, and the positioning seat 2 is provided with an axial hole 21 coaxial with the spray rod 12, and the shaft sleeve 111 can be rotatably sleeved in the axial hole 21 around its axis. The axial hole 21 is specifically located at the front end of the positioning seat 2, and the shaft sleeve 111 is located at the front end of the spray body 1. During installation, the shaft sleeve 111 at the front end of the spray body 1 is inserted into the axial hole 21 of the positioning seat 2 from back to front.

[0038] In this embodiment, a telescopic motor 13 is further provided on the spraying body 1, and the spraying rod 12 is driven by the telescopic motor 13 to achieve extension or retraction. The telescopic motor 13 can be specifically connected to the spraying rod 12 by a gear transmission assembly, and the gear transmission assembly includes a driving gear, a double-toothed transmission wheel and a synchronous belt. The driving gear is arranged on the output shaft of the telescopic motor 13, and the double-toothed transmission wheel is arranged at the front end of the spraying body 1, and one circle of the double-toothed transmission wheel is meshed with the first rack arranged on the spraying rod 12, and the synchronous belt is wound around the driving gear and the other circle of the double-toothed transmission wheel.

[0039] In this embodiment, a waterway switching component is provided on the spray bar 12. The waterway switching component includes a waterway switching member 15 movably arranged on the spray bar 12 and a switching motor 14 arranged on the spray bar 12. The waterway switching member 15 is driven by the switching motor 14 to enable the water inlet channel provided on the waterway switching member 15 to be switched and communicated with a plurality of waterways provided on the spray bar 12. Specifically, the waterway switching member 15 is slidably arranged on the spray bar 12, and a switching gear is arranged on the output shaft of the switching motor 14. The switching gear meshes with a second rack provided on the waterway switching member 15.

[0040] A spray cleaning device of the present invention is usually installed on the intelligent toilet cover of an intelligent toilet during application. In the initial state, the swing arm 33 remains in the vertical direction, and the spray bar 12 is in the retracted state, as Figure 4 、 Figure 5 shown. During operation, the telescopic motor 13 is started to drive the spray bar 12 to extend forward. When water is passed, a cleaning water column 4 that sprays obliquely upward is ejected from the front end of the spray bar 12, as Figure 8 shown. When the swing motor 31 is started, the swing motor 31 drives the driving wheel 34 to rotate a certain angle in the counterclockwise or clockwise direction at a certain speed. The driving wheel 34 drives the swing arm 33 to swing in one side (i.e., the left or right side) direction through the driving shaft 341 thereon. When the driving wheel 34 rotates to the maximum angle, the motor reverses to drive the driving wheel 34 to rotate to the maximum angle in the opposite direction, and the swing arm 33 also swings in the other side direction accordingly. In this way, a reciprocating cycle is realized to make the swing arm 33 swing left and right. As the swing arm 33 swings, the swing arm 33 drives the entire spray cleaning mechanism 1 to rotate and swing around the axis 121 of the spray bar under the guidance of the shaft hole 21 of the positioning seat 2, so that the water column 4 ejected from the front end of the spray bar 12 also swings to the left (as Figure 9 shown) and / or swings to the right (as Figure 10 shown).

[0041] When the spray cleaning mechanism 1 of the present invention only performs fixed-point left and right rotational swinging, a horizontal linear water splash can be obtained. When the rotational swinging of the present invention is combined with the forward and backward movement of the spray bar 12 and the swinging angle, moving displacement, etc. are controlled, various specific-shaped two-dimensional and three-dimensional water splash forms can be obtained. For example, when the spray cleaning mechanism 1 swings rotationally on one side (to the left or right), and at the same time, the spray bar 12 reciprocates with a small displacement back and forth, an elliptical water splash with the long axis in the horizontal direction can be obtained; when the spray cleaning mechanism 1 swings left and right rotationally, and at the same time, the spray bar 12 reciprocates with a small displacement back and forth, a combined water splash in the shape of an "8" can be obtained.

[0042] A spraying device of the present invention adopts the swing driving mechanism 3 to drive the entire spraying mechanism 1 to rotate and swing around the axis 121 of the spray rod, which can output a specific water spray pattern and improve the flushing experience. In addition, the swing driving mechanism 3 adopted by the present invention is a mechanical transmission method rather than a vibration driving method, which can solve the problems of easy loosening and misalignment of components existing in the vibration driving method.

[0043] A method of realizing swinging spray washing of the present invention is: setting the spray washing mechanism for hip washing and / or feminine washing to a state that it can rotate around the axis of the spray rod of the spray washing mechanism, and using a swinging drive mechanism to drive the spray washing mechanism to rotate and swing around the axis of the spray rod.

[0044] In this embodiment, the swing drive mechanism includes a swing motor, a fixed seat, a swing arm and a swing transmission structure. The swing arm can be swingably arranged on the fixed seat along the swing direction of the spray washing mechanism and is connected to the spray washing body. The output shaft of the swing motor is connected to the swing arm through the swing transmission structure to drive the swing arm to swing. The swing transmission structure includes a driving wheel and a long hole arranged on the swing arm, the long hole is located in the radial direction of the swing trajectory of the swing arm, the driving wheel and / or the swing motor are arranged on the fixed seat, and the driving wheel is driven by the swing motor. A driving shaft is arranged at the eccentric part of the driving wheel, the driving shaft is parallel to the output shaft of the swing motor, and the driving shaft is inserted into the long hole.
