Description

Technical Field

[0001] The invention relates to the technical field of toilets, and in particular to a toilet spray gun. Background Art

[0002] As one of the smart devices in modern home life, smart toilets integrate multiple functions to provide users with a more convenient, comfortable and hygienic experience. Smart toilets usually have multiple functions such as cleaning, heating, and sterilization. Among them, the cleaning function is usually achieved by installing a flushing pipeline in the seat of the toilet. A spray gun (nozzle) is set at the front end of the flushing pipeline, and the cleaning liquid of the flushing pipeline is sprayed from the spray gun to achieve the cleaning of private parts.

[0003] In the prior art, in order to ensure the spraying effect of the spray gun and facilitate use, a retractable spray gun is usually connected to the front end of the flushing pipeline. When the flushing operation is performed, the spray gun is extended from the seat ring to a set position, and then the spray is performed. After the flushing is completed, the nozzle is retracted into the seat ring. However, the existing spray gun still has the following problems: 1. Since the spray gun is constantly in and out of the toilet seat and performs cleaning actions, it is inevitably contaminated by the outside world and needs to be cleaned and sterilized regularly. However, existing spray guns generally only use clean water for self-cleaning, and the cleaning effect is poor. Moreover, since most spray guns extend from the rear end to the front end of the toilet seat to flush the private parts of the human body, there is a possibility that pollutants will adhere to the spray gun. Therefore, when the cleaning effect is poor, it is easy to cause bacteria to grow, which will cause infection risks to the private parts of the human body. 2. The existing spray guns can only be self-cleaned by water, and cannot remove bacteria on the spray guns. When bacteria grow on the spray guns, they need to be disinfected manually, which is very troublesome. In addition, it is impossible to determine whether the spray guns grow bacteria, which will cause users to frequently clean the spray guns, seriously increasing the cleaning workload of users and affecting the quality of life of users. 3. The extension and retraction of the existing spray gun is driven by water pressure, that is, the cleaning liquid with a certain pressure in the flushing pipeline pushes the spray gun to extend to flush the user's private parts. After the supply of cleaning liquid is stopped, the spray gun retracts under the action of the reset part. Since it is necessary to overcome the force of the reset part, a cleaning liquid with a higher pressure (clean water) is required. The cleaning liquid with a higher pressure causes poor comfort for the user when flushing, while the cleaning liquid with a lower pressure cannot ensure the reliable extension of the spray gun.

[0004] Therefore, it is a technical problem that is urgently needed to provide a spray gun that has a comfortable water spray pressure under the premise of reliable extension and can clean and disinfect the spray gun when the spray gun is in and out. Summary of the invention

[0048] The following is a detailed description in conjunction with the accompanying drawings and specific implementations. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0049] The toilet spray gun of the present application can be used in situations such as cleaning the user's private parts in a toilet, and of course can also be used in other similar application scenarios. The toilet spray gun is described in detail below.

[0050] See attached Figure 1 — Fig.17 The figure shows a schematic structural diagram of a preferred embodiment of a toilet spray gun of the present application. The toilet spray gun comprises an end cover 1, a shell 2 mounted on the end cover 1, a gun body 3 movably mounted in the shell 2, a spray head 4 detachably mounted on the end of the gun body 3 away from the end cover 1 through a buoyancy connection structure 6, a pneumatic control mechanism 5 mounted on the shell 2, and a disinfection mechanism 7 mounted on the front end of the shell 2; wherein a water inlet pipe is provided on the end cover 1.

[0051] The present invention adjusts the original water pressure to drive the gun body 3 to move by the air pressure difference through the setting of the pneumatic control mechanism 5, thereby driving the gun body 3 to move, thereby driving the gun body nozzle 4 to move, reducing the water pressure requirement, and increasing the adjustable range of water pressure on the premise of ensuring that the gun body 3 can be telescopically moved, so that the user can adjust the water pressure according to his or her preferences, thereby increasing the user's comfort; through the setting of the buoyancy connection structure 6, compared with the existing connection method using bolts or buckles, as long as the gun body 3 is filled with water, the nozzle 4 will be moved by buoyancy. The connection structure 6 is limited, and when the water level in the gun body 3 drops to insufficient buoyancy, the connection strength between the nozzle 4 and the gun body 3 will decrease, and the user can easily remove and replace it without the use of tools, and the force required to overcome is also small; through the setting of the disinfection mechanism 7, the nozzle part of the nozzle 4 can be cleaned and disinfected during the telescopic movement of the gun body 3, which can effectively prevent dirt from adhering to the nozzle 4, avoid the growth of bacteria on the nozzle 4, and avoid the user's private parts from being infected by the bacteria on the nozzle 4, thereby providing protection for the health and safety of the user.

[0052] See attached Figure 1 — Figure 6 As shown, in the present invention, the shell 2 includes a rear shell 21 connected to the end cover 1, and a front shell 22 fixedly mounted on the rear shell 21 by welding. The front shell 22 and the rear shell 21 form an integral structure by welding. Both the front shell 22 and the rear shell 21 are provided with an air cavity 23 and a mounting groove 24. The front shell 22 is also provided with a slide groove 25 which is vertically arranged and connected to the mounting groove 24.

[0053] The present invention arranges the shell 2 to be fixedly connected by welding the rear shell 21 and the front shell 22, so as to facilitate the processing of the air cavity 23 and the mounting groove 24, and at the same time, to facilitate the installation of the pneumatic control mechanism 5; through the arrangement of the air cavity 23, conditions are provided for controlling the movement of the gun body 3 by the air pressure difference; and through the arrangement of the mounting groove 24, an installation position is provided for the gun body control component 52.

[0054] See attached Figure 1 — Figure 3 As shown, in the present invention, the pneumatic control mechanism 5 includes an air source transmission component 51, a gun body control component 52, an air pressure monitoring component 53 and a buoyancy control component 54; wherein, the air source transmission component 51 is connected to the outer shell 2, and is used to provide an air source for the gun body 3; the gun body control component 52 is installed on the outer shell 2 and is connected to the gun body 3, and the gun body 3 is moved by the gas of the air source transmission component 51; the air pressure monitoring component 53 is used to provide feedback to the air source transmission component 51, and to perform precise control of the air pressure; the buoyancy control component 54 is installed on the outer shell 2 and the nozzle 4, and is used to control the amount of water in the nozzle 4 and the gun body 3; and through the setting of the slide groove 25, it is used to provide necessary conditions for the movement of the gun body control component 52.

[0055] The present invention is used to provide an air source for the movement of the gun body 3 through the setting of the air source transmission component 51, and transmit the gas into the air cavity 23; through the setting of the gun body control component 52, the movement is generated by the air pressure difference between the two air cavities 23, thereby driving the gun body 3 to move, and the two air cavities 23 are isolated and sealed to improve the reaction speed of the movement of the gun body 3; through the setting of the air pressure monitoring component 53, the air pressure of the two air cavities 23 is accurately controlled, so as to achieve the control of the moving position of the gun body 3, so that the position of the gun body 3 when in use and when replacing the nozzle 4 is different. Specifically, there are two working positions when the gun body 3 is extended, one is for replacing the nozzle 4, and the extension distance of the gun body 3 is longer, which is convenient for replacing the nozzle 4, and the disinfection mechanism 7 can be used for cleaning or replacement, and the other working position is used for flushing the user's private parts.

[0056] See attached Figure 1 and Figure 3 As shown, in the present invention, the gas source transmission component 51 includes a micro air pump 511, a reversing valve 512 installed on the air outlet of the micro air pump 511, a transmission tube 1 513 and a transmission tube 2 514 installed on the reversing valve 512, and two electrically controlled exhaust valves 515 respectively installed on the transmission tube 1 513 and the transmission tube 2 514; the transmission tube 1 513 and the transmission tube 2 514 are respectively connected to the two air cavities 23.

[0057] The present invention provides an air source through the setting of a micro air pump 511, so that an air pressure difference is generated in the two air cavities 23; through the setting of a reversing valve 512, it is used to control the movement direction of the gas, that is, to control the gas of the micro air pump 511 to enter one of the air cavities 23, and the reversing valve 512 can be a two-position three-way reversing valve; through the setting of a transmission tube 1 513 and a transmission tube 2 514, it is used to connect the two air outlets of the reversing valve 512 to two different air cavities 23 respectively; through the setting of an electrically controlled exhaust valve 515, it is used to inflate one of the air cavities 23, and when the air pressure increases, the other air cavity 23 can be deflated.

[0058] See attached Figure 3 — Figure 7 As shown, in the present invention, the gun body control assembly 52 includes a control ring 521 movably installed in the air cavity 23, a control connecting plate 522 connected to the control ring 521, a control buffer structure 523 installed on the control connecting plate 522, and a limit block 524 installed on the control connecting plate 522, wherein the limit block 524 is made of magnetic conductive material.

[0059] The present invention is used to isolate and separate the two air cavities 23 through the setting of the control ring 521, so that the air pressure in the two air cavities 23 can form an air pressure difference, and the air pressure difference forms power to drive the gun body 3 to move; by controlling the setting of the connecting plate 522, the control ring 521 can transmit the moving power of the control ring 521 during the movement, so as to drive the gun body 3 to move; by controlling the setting of the buffer structure 523, the moving speed of the gun body 3 is buffered after the gun body 3 moves to the specified position, so as to prevent the gun body 3 from moving too fast and causing collision, avoid damage to the gun body 3 due to collision after long-term use, and avoid vibration caused by collision affecting the air tightness between the air cavity 23 and the control ring 521, thereby extending the service life of the spray gun; by setting the limit block 524, after the gun body 3 moves to the extreme position for replacing the spray head 4, the position of the gun body 3 can be limited, so as to ensure that the user has enough time to replace the spray head 4.

[0060] See attached Figure 3 — Figure 6As shown, in the present invention, a boss 221 is provided in the inner cavity of the front shell 22, and a buffer pad 222 in contact with the control buffer structure 523 is installed on the boss 221; a groove 223 is formed between the outer wall of the boss 221 and the inner wall of the front shell 22, and an electromagnet 224 corresponding to the limit block 524 is installed in the groove 223; the distance from the center position of the control ring 521 to the limit block 524 is greater than the distance from the center position of the control ring 521 to the control buffer structure 523; wherein, a moving structure 26 is installed in the mounting groove 24, and a control connecting plate 522 is connected to the moving structure 26, and the control connecting plate 522 corresponds to the slide groove 25, and the control connecting plate 522 is connected to the gun body 3; the two air cavities 23 are separated by the control ring 521, and the transmission tube 1 513 and the transmission tube 2 514 are respectively located on both sides of the control ring 521.

[0061] The present invention cooperates with the control buffer structure 523 through the setting of the boss 221, so that the gun body 3 can be buffered before the gun body 3 is extended; the buffer pad 222 is set to prevent hard collision and reduce vibration; the groove 223 is set to provide an installation position for the electromagnet 224, ensuring that the control buffer structure 523 contacts the buffer pad 222 first, and the limit block 524 will contact the electromagnet 224 only after the control buffer structure 523 is contacted and compressed.

[0062] See attached Figure 7 and Figure 8 As shown, in the present invention, the control buffer structure 523 includes a telescopic column 5231 installed on the control connecting plate 522, a telescopic sleeve 5232 mounted on the telescopic column 5231, a cover 5233 installed on the telescopic sleeve 5232, a limit plate 5234 installed on the telescopic column 5231 and located in the telescopic sleeve 5232, and a spring 5235 installed in the telescopic sleeve 5232, and the two ends of the spring 5235 are in contact with the limit plate 5234 and the cover 5233 respectively.

[0063] The working principle of the control buffer structure 523 is as follows: when the gun body 3 moves to a certain distance, the cover 5233 on the telescopic sleeve 5232 contacts the buffer pad 222. As the control connecting plate 522 continues to move, the telescopic column 5231 will continue to move, and the spring 5235 will be squeezed and buffered through the limit plate 5234.

[0086] See attached Figure 1 — Fig.17 As shown, the use process of the present invention is as follows: Flushing process: First, the user issues a command to the controller to flush the private parts through an external button. After receiving the command, the controller of the toilet controls the micro air pump 511 to start working, controls the reversing valve 512 to allow the gas generated by the micro air pump 511 to enter the air cavity 23 in the rear shell 21 through the transmission tube 1 513, and simultaneously opens the electrically controlled exhaust valve 515 on the transmission tube 2 514 to discharge the gas in the air cavity 23 on the front shell 22. A pressure difference is generated between the two air cavities 23, which pushes the control ring 521 to move. The control ring 521 drives the gun body 3 and the moving plate 263 to move by controlling the connecting plate 522, so that the gun body 3 drives the nozzle 4 to extend. In the process of the movement of the gun body 3, the buffer structure 523 is controlled to buffer until the gas in the air cavity 23 is filled. The air pressure value reaches the specified value, so that the air pressure difference reaches the specified value, so that the gun body is in the specified position; then the controller controls the pump body of the toilet to work, and adds pressurized clean water to the end cover 1. The clean water flows into the gun body 3 through the through hole 321 on the water blocking plate 32, enters the nozzle 4 through the flow hole 35 of the gun body 3, and is finally sprayed out from the nozzle 4 to rinse the user's private parts; after the cleaning is completed, the controller controls the reversing valve 512 to start working, and applies the gas generated by the micro air pump 511 into the air cavity 23 of the front shell 22, closes the electrically controlled exhaust valve 515 on the transmission tube 2 514, and opens the electrically controlled exhaust valve 515 on the transmission tube 1 until the gun body 3 is reset. The air pressure in the air cavity 23 on the rear shell 21 can be used to judge whether the gun body 3 is reset.

[0087] Disinfection process: When the controller receives the instruction to flush the private parts, the controller controls the micro air pump 511 to start working. When performing the flushing step, it also controls the disinfectant to start discharging. The disinfectant enters the disinfection hole 731 of the rotating column 73 through the liquid inlet pipe 71 and the liquid inlet 721, and then flows out from the liquid outlet 732 to disinfect the nozzle 4. At the same time, when the gun body 3 is telescopically moved, the nozzle 4 will contact the bristles 74, and the bristles 74 will scrub the nozzle 4, thereby cleaning the dirt, and the disinfectant will remain along the bristles 74 to disinfect the nozzle 4. It should be noted that the controller will wait for the time to discharge the disinfectant and disinfect the nozzle 4 regularly.

[0088] The process of replacing the nozzle 4 and the bristles: the user sends a replacement signal to the controller through an external button. After the controller receives the replacement signal, the controller controls the micro air pump 511 to start working, controls the reversing valve 512 to allow the gas generated by the micro air pump 511 to enter the air cavity 23 in the rear shell 21 through the transmission tube 1 513, and at the same time opens the electrically controlled exhaust valve 515 on the transmission tube 2 514 to discharge the gas in the air cavity 23 on the front shell 22. The two air cavities 23 produce an air pressure difference, which pushes the control ring 521 to move. The control ring 521 drives the gun body 3 and the moving plate 263 to move by controlling the connecting plate 522, so that the gun body 3 drives the nozzle 4 to extend. In the process of the movement of the gun body 3, the buffer structure 523 is controlled to buffer. At the same time, the controller controls the electromagnet 224 to be energized, and the spring 5235 in the buffer structure 523 is continuously compressed until the limit block 524 contacts the electromagnet 224; then the controller controls the reversing valve 512 to change The electric-controlled exhaust valve 515 on the transmission pipe 514 is closed. At this time, the air pressure in the air cavity 23 on the front shell 22 increases. As the pressure in the air cavity 23 on the front shell 22 increases, the gas will enter the lifting and moving pipe 546 along the buoyancy control pipe 541 through the connecting pipe 545. As the air pressure continues to rise, the control board 547 will be lifted up. As the control board 547 rises, the clean water in the nozzle 4 and the gun body 3 will flow out through the water outlet 542, and the control board 547 will continue to rise. It rises until the air hole 548 is connected with the inner cavity of the nozzle 4. As the clean water in the gun body 3 and the nozzle 4 flows out, the buoyancy connection column 62 drops, so that the plug column 621 is separated from the connection hole 63. At this time, the nozzle 4 is only magnetically attracted by the magnetic block 41 and the magnet 311. The user can easily remove the nozzle 4, and then install a new nozzle 4 on the gun body 3. It can be reset by controlling the external controller. When replacing the nozzle 4, the bristles 74 on the nozzle 4 are also replaced. During the reset process, the controller will first close the cover of the toilet, open the electrically controlled exhaust valve 515 on the second transmission pipe 514, and reduce the air pressure in the air cavity 23 on the front shell 22. After the air pressure drops to a specified level, clean water is introduced into the gun body 3, and then the electromagnet 224 is powered off to reset in the same way as the flushing process. When replacing the nozzle 4, as the nozzle 4 moves, the disassembly spring 89 will be compressed at the beginning, and as the nozzle 4 continues to move, the elastic force of the disassembly spring 89 continues to increase. When it moves to the end, the elastic force generated by the disassembly spring 89 is sufficient to make the rotating column 73 overcome the protrusion 722 and slide out; it should be particularly noted that the rotating column 73 can be removed from the disassembly groove 83 by rotating the limiting mounting plate 85, and then a new rotating column 73 can be replaced or the bristles 74 can be cleaned and reinstalled; and in the process of resetting the gun body 3, the limiting mounting plate 85 limits the rotating column 73, and the rotating column is rotated to pass over the protrusion 722 during resetting.

[0089] The above embodiments are intended to illustrate the present application, not to limit the present application. Any solution that is a simple transformation of the present application falls within the protection scope of the present application.
