Description

Technical Field

[0001] The present invention relates to the technical field of bathtubs, and in particular to a bathtub cleaning device and a cleaning control method. Background Art

[0002] Bathtub cleaning has always been an unavoidable problem in the use of bathtubs. The usual practice is to use a handheld shower to manually flush the inner wall of the bathtub after use. This method is of course effective, but it is relatively complicated to manually clean and add detergent manually. There are also some products that install nozzles on the inner wall of the bathtub to spray downward at a certain angle, but the spray angle has certain restrictions, so multiple nozzles must be installed to complete it (the number of nozzles varies from 6 to 8 depending on the size and shape of the bathtub). In this way, a circle of nozzles above the inner wall of the bathtub will directly affect the beauty of the entire bathtub, which is contrary to the simple design concept of the bathtub. In addition, the installation of multiple nozzles is complicated and prone to failure. In addition, since the edge of the nozzle is made very thin, the nozzle located on the backrest also has the risk of scratching people. There are also some products that install a rotating nozzle at the bottom of the bathtub to achieve the cleaning effect, but because the water is sprayed from the bottom to the top, a cover must be added to ensure that the water will not spray to other places outside the bathtub, which will also add an extra step to cover the lid, and there is also a certain risk of clogging when the spray hole is facing upward. Summary of the invention

[0003] The present invention aims to solve at least one of the above-mentioned technical problems in the related art to a certain extent. To this end, the present invention provides a bathtub cleaning device.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] The present invention also provides a cleaning control method based on the bathtub cleaning device.

[0006] According to the first aspect of the present invention, the bathtub cleaning device includes a flip body, a flip drive mechanism, a water outlet and a liquid supply system. One end of the flip body is rotatably installed on one side of the bathtub. The flip drive mechanism is transmission-connected with the flip body to drive the flip body to rotate. The water outlet is installed on the flip body. The flip body can be rotated to a horizontal state. When the flip body is in a horizontal state, the water outlet is located above the bathtub. The water outlet is connected to the liquid supply system through a hose. The water outlet has a plurality of water outlet channels, and the plurality of water outlet channels are radially distributed from the center to the outside.

[0007] The bathtub cleaning device according to the embodiment of the present invention has at least the following beneficial effects:

[0008] 1. When the bathtub needs to be cleaned, the flip drive mechanism drives the flip body to rotate to a horizontal state, so that the water outlet is located above the bathtub.

They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] Referring to Figures 1-5, a bathtub cleaning device includes a flip body, a flip driving mechanism, a water outlet 300 and a liquid supply system. One end of the flip body is rotatably mounted on one side of the bathtub 500. The flip driving mechanism is transmission-connected with the flip body to drive the flip body to rotate. The water outlet 300 is mounted on the flip body. The flip body can rotate to a horizontal state. When the flip body is in a horizontal state, the water outlet 300 is located above the middle of the bathtub 500. The water outlet 300 is connected to the liquid supply system through a hose. The water outlet 300 has a plurality of water outlet channels 333, and the plurality of water outlet channels 333 are radially distributed from the center to the outside. Specifically, the flip body is mounted on the top of the side wall of the bathtub 500 on the side close to the wall.

[0044] When the bathtub 500 of the present invention needs to be cleaned, the flip driving mechanism drives the flip body to rotate to a horizontal state, so that the water outlet 300 is located above the middle of the bathtub 500. Since the water outlet flow channel 333 is radially distributed from the center to the outside, water flows through the water outlet flow channel 333 and sprays in all directions, achieving the effect of spraying water in all directions, and cleaning the inner wall of the bathtub 500 in 360 degrees, as shown in FIG3. After cleaning, the flip body rotates upward to the side of the bathtub 500 and is stored vertically, which is convenient for entering and exiting the bathtub 500 and prevents the flip body from accumulating water.

[0045] In some embodiments of the present invention, referring to FIGS. 6-9, the water outlet member 300 includes a water inlet base 310, a locking nut 320 and a water outlet nozzle 330, and a mounting hole 121 is opened on the flip body. The water inlet base 310 has a first water inlet portion 311 and a first water outlet portion 313 that are connected to each other. The first water outlet portion 313 is tubular, and its inner peripheral wall has a first thread and the outer peripheral wall has a second thread. The water inlet base 310 also has a limiting flange 314, and the limiting flange 314 is located above the first water outlet portion 313, and the first water outlet portion 313 is inserted into the mounting hole 121. 21, the limiting flange 314 abuts against the upper surface of the flip body, the first water outlet portion 313 is connected to the locking nut 320 through the second thread, and the locking nut 320 abuts against the lower surface of the flip body, the water outlet nozzle 330 has a second water inlet portion 331 and a second water outlet portion 332 that are connected, the second water inlet portion 331 is tubular, and its outer peripheral wall has a third thread, the first thread is connected to the third thread, and the second water outlet portion 332 has a plurality of water outlet channels 333, and the plurality of water outlet channels 333 are radially distributed from the center of the second water outlet portion 332 to the outside. The water outlet nozzle 330 is designed to be detachable, and the water inlet base 310 is an internal and external thread structure. The external second thread is used to cooperate with the locking nut 320 to fix the water inlet base 310 on the flip body, and the internal first thread serves to support the water outlet nozzle 330. Since the water inlet base 310 is already fixed, removing the water outlet nozzle 330 from the front of the flip body will not affect the structural stability and sealing of other components, which facilitates the replacement or maintenance of the water outlet nozzle 330.

[0046] In some embodiments of the present invention, the water outlet channel 333 is arranged to be inclined downward from the center outward, the end of the water outlet channel 333 located inside the second water outlet portion 332 is the water inlet end, and the end located outside the second water outlet portion 332 is the water outlet end. The distance between the vertical walls on both sides of the water outlet channel 333 is the width d of the water outlet channel 333, and the width d of the water outlet channel 333 gradually increases from the water inlet end to the water outlet end, as shown in FIG8. The water outlet channel 333 is inclined downward at a certain angle to form an umbrella-shaped diffusion spray structure, and the scattered water is sprayed from top to bottom, ensuring that the places outside the bathtub 500 will not be disturbed by the water flow, while also reducing the steps of the cover, and the angle formed by the water flow diffusion will not exceed 180°, ensuring that the water flow will not be excessively diffused upward or outward when spraying, and reducing the rebound splash of the water flow reaching the surface of the bathtub 500. The width d of the water outlet channel 333 gradually increases from the inside to the outside, forming an expansion shape, which can effectively diffuse the water flow and increase the coverage area. The present invention changes the inclination and width of the flow channel so that the water flow forms an umbrella-like diffusion shape after being sprayed out, and the water flow can evenly cover a larger area instead of being concentrated on one point.

[0047] In some embodiments of the present invention, the distance between the upper wall 110 and the lower wall 120 of the water outlet flow channel 333 is the height h of the water outlet flow channel 333, and the height h of the water outlet flow channel 333 gradually increases from the water inlet end to the water outlet end, as shown in Figure 9. As the height of the water outlet flow channel 333 increases, the water flow has more space to diffuse, and the flow rate will be relatively reduced, which helps to reduce the flow rate at the outlet, so that the water flow can be more evenly distributed in a wider area, thereby covering a larger spraying area.

[0048] In some embodiments of the present invention, the flip body is arranged horizontally, and the upper wall 110 is inclined downwardly at an angle α of 12-17° relative to the flip body, as shown in Figure 9. Since the water has a diffusion angle of about 3° after leaving the nozzle, in order to ensure that the flip body is not sprayed by water, a certain angle needs to be left between the water outlet channel 333 and the flip body, while ensuring that the water outlet angle is maximized.

[0049] In some embodiments of the present invention, the angle β formed by the extended surface of the upper wall 110 and the extended surface of the lower wall 120 is 12-17°, as shown in Fig. 9. If the angle β is too large, the flow rate is too low and it is difficult to reach the inner wall of the bathtub 500. Controlling the angle β within 12-17° ensures both the water flow coverage area and the spraying speed.

[0050] In some embodiments of the present invention, the outer peripheral wall of the upper portion of the second water outlet 332 is provided with anti-skid vertical lines 336. The anti-skid vertical lines 336 are used to increase friction, and the disassembly and assembly can be completed by hand without the aid of tools.

[0051] In some embodiments of the present invention, the mounting hole 121 is a countersunk hole, the locking nut 320 is completely embedded in the mounting hole 121, and the lower end surface of the locking nut 320 is provided with two grooves 321, and the two grooves 321 are symmetrically arranged with the axis of the locking nut 320 as the center. The countersunk hole structure makes the appearance of the water outlet component more concise, and the locking nut 320 is integrally embedded in the countersunk hole and is not easy to loosen due to misoperation. Use a tool to apply torque to the two symmetrical grooves 321, and the locking nut 320 can be rotated to lock or loosen.

[0052] In some embodiments of the present invention, a sealing gasket 340 is further included. The water inlet base 310 has a water passage cavity 315, which is located between the first water inlet portion 311 and the first water outlet portion 313. The first water inlet portion 311 and the first water outlet portion 313 are connected through the water passage cavity 315. An annular groove is provided on the inner peripheral wall of the water passage cavity 315. The sealing gasket 340 is embedded in the annular groove, and the top end of the second water inlet portion 331 is pressed against the sealing gasket 340. The sealing gasket 340 forms an effective sealing interface to prevent the fluid flowing in the water passage cavity 315 from leaking to the outside. The sealing gasket 340 can also increase the stability of the connection, increase the friction at the connection, help maintain the stability of the structure, and prevent loosening due to vibration or other external forces.

[0053] In some embodiments of the present invention, the first water inlet 311 is a tubular structure, the axis of which is arranged in the horizontal direction, and the outer peripheral wall of the first water inlet 311 is partially in the form of a tower-shaped structure 312, and the tower-shaped structure 312 is located at the water inlet of the first water inlet 311. The water pipe connection adopts a tower-shaped insertion method, and the tower-shaped structure 312 has a plurality of tapered sections, each layer of which can firmly grasp the inner wall of the hose, thereby increasing the friction between the first water inlet 311 and the hose, and ensuring that the hose will not easily slip off under water pressure.

[0054] In some embodiments of the present invention, the flip body is a small table 100, which has an upper wall 110 and a lower wall 120. The upper wall 110 is provided with a storage groove 111, and the mounting hole 121 is opened in the lower wall 120. The water inlet base 310 is located in the cavity between the upper wall 110 and the lower wall 120. A water inlet pipe 130 is also arranged in the cavity. One end of the water inlet pipe 130 is connected to the first water inlet part 311, and the other end passes through the side wall of the small table 100 and is connected to the liquid supply system. The second water outlet 332 is located below the lower wall 120. The small table 100 integrates the storage function and the cleaning function into one. Mobile phones, tablet computers, water cups and other items can be placed on the small table 100, and spraying from top to bottom can be achieved to clean the inner wall of the bathtub 500 360 degrees. The water inlet pipe 130 is built into the small table 100 and cannot be seen from the outside, so as to keep the product appearance simple. It is understandable that the small table 100 can be replaced by a simple rocker.

[0055] In some embodiments of the present invention, a rotating shaft 600 is further included. The top of one side wall of the bathtub 500 has a mounting side 510 that is turned toward the outside of the bathtub 500. A mounting through slot 511 is opened on the mounting side 510. A fixing bracket 700 is passed through the mounting through slot 511. The lower part of the fixing bracket 700 is located below the mounting side 510 and is fixed to the bathtub 500. The fixing bracket 700 has a first mounting foot 710 and a second mounting foot 720. The first mounting foot 710 and the second mounting foot 720 are located above the mounting side 510. Both ends of the rotating shaft 600 are respectively passed through the first mounting foot 710 and the second mounting foot 720. Both ends of the rotating shaft 600 are connected to the flip body. A first gear 610 is fixedly sleeved on the rotating shaft 600. The flip driving mechanism includes a motor 210 and a second gear 220. The second gear 220 is coaxially connected to the output shaft of the motor 210, and the first gear 610 is meshed with the second gear 220. Furthermore, a waterproof cover is provided above the installation slot 511 to cover the shaft 600, the gear, the motor 210, and the installation slot 511, and an opening is provided on the waterproof cover for the hose to pass through. The flipping function is achieved by the reduction motor 210, the gear set, and the shaft 600 driving the entire small table 100 to operate. Specifically, the gear driven by the reduction motor 210 rotates, and the gear drives the shaft 600 to rotate. Both ends of the shaft 600 are fixedly connected to the small table 100 to achieve the up and down rotation of the small table 100.

[0056] In some embodiments of the present invention, the fixing bracket 700 further has a third mounting foot 730 , which is located between the first mounting foot 710 and the second mounting foot 720 , and the motor 210 is fixedly mounted on the third mounting foot 730 .

[0057] In some embodiments of the present invention, the rotation range of the flip body is 0°-92°, where 0° means the flip body is in a horizontal state, and 92° means the flip body flips upward 92° from the horizontal state, as shown in FIG2. The system is set to spray water normally only when it is docked at the 0° position, and the water channel is in a normally closed state at other angles to avoid misoperation of water discharge. The flip body can be in a relatively safe position when docked normally, and at the same time, it is deflected 2° backward relative to the vertical state, so that the flip body is as close to the wall as possible, and the space for entering and exiting the bathtub 500 can be larger.

[0058] In some embodiments of the present invention, the liquid supply system includes a detergent pipeline 410, a clean water pipeline 420, a main pipeline 430 and a detergent storage tank 440. The detergent pipeline 410 and the clean water pipeline 420 are connected to one end of the main pipeline 430 through a three-way joint, and the other end of the main pipeline 430 is connected to the water outlet 300. The detergent pipeline 410 is connected to the detergent storage tank 440. A peristaltic pump 450 is provided on the detergent pipeline 410, and a solenoid valve 460 is provided on the clean water pipeline 420. Through the peristaltic pump 450, a detergent can be quantitatively added to the main pipeline 430. The water outlet 300 is located below the small table 100, and sprays clean water or a mixed liquid containing a detergent downward to achieve the purpose of cleaning the bathtub 500. The water inlet of the clean water pipeline 420 can be operated by tap water pressure, or by a front-end pump pressurization method. The liquid supply system is installed as a whole on the side of the bathtub 500 against the wall and is blocked by the bathtub 500.
