Description

Technical Field

[0001] This utility model relates to the field of toilet technology, specifically to a dual-knob control device for toilets. Background Technology

[0002] With the advancement of technology and the continuous improvement of people's living standards, smart toilets are gradually entering thousands of households. Currently, some smart toilets mainly use a rotary switch set on the toilet seat to control various mechanisms to achieve functions such as flushing and drying.

[0003] Some smart toilets already use dual knobs installed on the outside of the toilet. However, these knobs often require rotating the body to control the smart toilet, which not only causes some hygiene problems due to touching, but is also inconvenient for some disabled or obese people to use. To address this, we propose a dual knob control device for toilets to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a dual-knob control device for toilets to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-knob control device for a toilet, comprising a mounting bracket, a protective shell, and knob bodies. The protective shell is fixedly connected to the top of the mounting bracket. Two knob bodies are installed on the toilet along with the mounting bracket. Each knob body is located inside the protective shell, with its top end extending to the outside of the protective shell. Several locking teeth are equidistantly mounted around the surface of the knob body inside the protective shell. Electric telescopic columns are symmetrically mounted on the inner wall of the protective shell. A drive assembly for rotating the knob bodies is fixedly mounted on the telescopic end of each electric telescopic column. A PLC controller is also mounted on the side wall of the protective shell.

[0006] Furthermore, the drive assembly includes a housing, one end of which is fixedly mounted with a stepper motor. The output shaft of the stepper motor passes through the inner side of the housing and is fixedly connected to a lead screw. The surface of the lead screw is threadedly connected to a rack plate that engages with the locking teeth.

[0007] Furthermore, a guide slider is fixedly installed on the outer side of the rack plate, and a guide groove is provided on the inner wall of the housing to cooperate with the guide slider.

[0008] Furthermore, the knob body is specifically adopted as either a non-automatic return knob or an automatic return knob, and the surface of the knob body located outside the protective shell is provided with anti-slip texture.

[0009] Furthermore, the PLC controller is electrically connected to both the electric telescopic column and the stepper motor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model uses a PLC controller to control the electric telescopic column and the stepper motor. When it is necessary to rotate a certain knob, the corresponding electric telescopic column can be opened using a remote control, causing its telescopic end to move the drive component towards the knob body. Simultaneously, the stepper motor is activated, causing its output shaft to rotate a certain number of times, driving the lead screw to rotate synchronously. The rack plate threaded onto it can move laterally a certain distance under the limit of the guide slider and guide groove. The locking teeth meshing with the rack plate can drive the corresponding knob body to rotate a certain angle, thus achieving remote control of the knob body's rotation. This toilet uses a dual-knob control device with a reasonable structural design and convenient use. It allows for automatic and precise rotation of both knobs via remote control, replacing the traditional method of manual rotation. This avoids hygiene problems caused by touching the knob and is also suitable for people with disabilities and obesity, demonstrating good performance. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1:

[0018] Please see Figure 1-3A dual-knob control device for a toilet includes a mounting bracket 1, a protective shell 2, and a knob body 3. The protective shell 2 is fixedly connected to the top of the mounting bracket 1. There are two knob bodies 3, which are installed on the toilet together with the mounting bracket 1. The two knob bodies 3 are used to control the flushing flow rate and the switching of the flushing mode. Each time they are rotated by a certain angle, different flushing volumes and different flushing modes are achieved. Both knob bodies 3 are electrically connected to the main control circuit of the smart toilet. This is a mature existing technology and will not be described in detail here. The knob body 3 is located inside the protective shell 2 and its top extends to the outside of the protective shell 2. The knob body 3 is a non-automatic return knob. The surface of the knob body 3 located outside the protective shell 2 has anti-slip texture. The surface of the knob body 3 located inside the protective shell 2 has several teeth 4 installed around it at equal intervals. Electric telescopic columns 5 are symmetrically installed on the inner wall of the protective shell 2. The telescopic end of the electric telescopic column 5 is fixedly installed with a drive component 6 for rotating the knob body 3. A PLC controller 7 is also installed on the side wall of the protective shell 2.

[0019] The drive assembly 6 includes a housing 61, a stepper motor 62 is fixedly mounted on one end of the housing 61, the output shaft of the stepper motor 62 passes through the inner side of the housing 61 and is fixedly connected to a lead screw 63, the surface of the lead screw 63 is threadedly connected to a rack plate 64 that cooperates with the locking teeth 4, a guide slider 65 is fixedly mounted on the outer side of the rack plate 64, and a guide groove that cooperates with the guide slider 65 is provided on the inner wall of the housing 61.

[0020] The PLC controller 7 is electrically connected to the electric telescopic column 5 and the stepper motor 62. It can control the electric telescopic column 5 and the stepper motor 62 via an external remote control. When the number of teeth 4 on the surface of the knob body 3 is set to thirty-six, each rotation of one tooth 4 represents a ten-degree rotation. If the knob body 3 rotates thirty degrees, a new mode is switched, controlling the rotation of three tooth 4 units. Correspondingly, when the rack plate 64 moves laterally, it also moves a corresponding distance. The movement distance of the rack plate 64 is affected by the number of rotations of the lead screw 63. When the pitch of the lead screw 63 is determined, each rotation of the rack plate... The moving distance of plate 64 is also determined accordingly. Then, the PLC controller 7 can be programmed so that each time the remote control button is pressed, the output shaft of stepper motor 62 drives the lead screw 63 to rotate a fixed number of turns, so that the rack plate 64 moves a fixed distance, thereby driving the meshing teeth 4 and the knob body 3 to rotate a fixed angle, so as to realize the adjustment of the flushing volume and flushing mode. After use, the output shaft of stepper motor 62 is controlled to rotate in the opposite direction by the remote control, so that the rack plate 64 returns to its original position, and then the electric telescopic column 5 is controlled to return to its original position to prevent the rack plate 64 from meshing with the teeth 4, which would affect the direct rotation of the knob body 3.

[0021] This toilet uses a dual-knob control device with a reasonable structural design and convenient use. The two knobs can be automatically rotated and precisely rotated at a certain angle via remote control, replacing the traditional method of manually rotating the toilet body. This avoids some hygiene problems caused by touching the body and is also suitable for some disabled and obese people, with good usage effect.

[0022] In use, the electric telescopic column 5 and the stepper motor 62 are controlled by the PLC controller 7. When it is necessary to rotate a certain knob body 3, the corresponding electric telescopic column 5 can be opened by the remote control, so that its telescopic end drives the drive component 6 to move to one side of the knob body 3. The stepper motor 62 is also opened, so that its output shaft rotates a certain number of times, driving the lead screw 63 to rotate synchronously. The rack plate 64 threaded on it can move laterally a certain distance under the limit of the guide slider 65 and the guide groove. The clasping teeth 4 that mesh with the rack plate 64 can drive the corresponding knob body 3 to rotate a certain angle, thereby realizing remote control of the rotation of the knob body 3.

[0023] Example 2:

[0024] Unlike Embodiment 1, the knob body 3 used in this embodiment is an automatic return knob. Accordingly, after the knob body 3 is controlled, the electric telescopic column 5 should be controlled to return to its original position first. This way, the locking teeth 4 will disengage from the rack plate 64 and automatically return to its original position. After the electric telescopic column 5 returns to its original position, the stepper motor 62 can be controlled to drive the rack plate 64 to return to its original position for the next use.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
