Description

[Technical Field]

[0001] The present application relates to the field of oral irrigators, and more particularly to dual tank oral irrigators. [Background technology]

[0002] Oral irrigators are auxiliary tools for cleaning the mouth, using the impact of pulsating water to clean teeth and between teeth. The main effect of mouthwash (gargles) is to clean the mouth, mask bad breath caused by bacteria or yeast breaking down food residue, and leave the mouth feeling pleasant and fresh. The two functions complement each other, and users usually use the oral irrigator to clean their teeth and then the mouthwash to rinse their mouth. However, both oral irrigators and mouthwash (generally bottled) take up space, so there is a need for improved portability when traveling.

[0003] The utility model with license publication number CN213130038U discloses a dual-tank oral irrigator, which is designed with two tanks and two pipes to allow different liquids to be charged, meeting the needs of users. However, its structure is complex, the pipes take up a relatively large amount of space, and the switch that controls the liquid flow causes wear on the pipes, so its stability and durability still need to be improved.

[0017] In the following, exemplary embodiments of the present application will be described with reference to the accompanying drawings. It should be understood that the specific description is merely intended to teach those skilled in the art how to implement the present application, but does not represent all possible implementations of the present application, nor does it limit the scope of the present application.

[0018] An embodiment of the present application provides a dual tank oral irrigator (hereinafter, sometimes abbreviated as "oral irrigator").

[0019] Referring to FIGS. 1 to 6, the dual tank oral irrigator may include a rotary valve 100, a first tank 210, a second tank 220, a water conduit 300, and a pump assembly 400.

[0020] 7, 8, and 9, the rotary valve 100 may include an outlet port 110, a first inlet port 120, a second inlet port 130, a valve element 140, and a valve core 150. By rotating the valve core 150 to adjust the degree of sealing of the valve core 150 with the first inlet port 120 and the second inlet port 130, the liquid source flowing through the rotary valve 100 can be selected.

[0021] 6, the first inlet 120 is connected to the first tank 210, the second inlet 130 is connected to the second tank 220, and the outlet 110 is connected to one end of the water conduit 300. Referring to FIG. 5, the pump assembly 400 is connected to the other end of the water conduit 300 and to a nozzle 500 of the oral irrigator, and a nozzle 510 may be further installed outside the nozzle 500 (see FIGS. 1, 2, and 3).

[0022] As shown by the dotted arrow in Fig. 5, the liquid passes through the water guide pipe 300 and the pump assembly 400 before being ejected from the ejection port 500. Referring to Fig. 4, the first tank 210 can store a spray cleaning liquid (e.g., clean water), and the second tank 220 can store a mouthwash (e.g., a mouthwash), and the volume of the first tank 210 can be larger than the volume of the second tank 220.

[0023] It should be noted that the rotary valve 100 in this application is applied to an oral irrigator, and the liquid switching process is simple. After completing oral irrigation using the spray rinse, the user can adjust the rotary valve 100 and rinse their mouth with the mouthwash sprayed from the oral irrigator, eliminating the need to carry two separate hygiene products, an oral irrigator and a mouthwash bottle, making it more portable. Since this application uses only one water conduit 300, rather than two pipes (water conduits) as in the background art, the structure is relatively simple and the space allocation is more reasonable. Since the water conduit 300 is not worn out during the process of switching the operating position of the rotary valve 100, the oral irrigator is more robust and durable.

[0024] 6 to 9, in one embodiment of the present application, a valve body 140 may include a main portion 141 and a first inlet portion 120, a second inlet portion 130, and an outlet portion 110 extending from the main portion 141, where the first inlet portion 120 and the second inlet portion 130 are at the same circumferential position on the circumferential surface of the main portion 141 and are parallel to each other in the axial direction. A valve core 150 includes a first sealing portion 151 and a second sealing portion 152 disposed on its circumferential surface, where the first sealing portion 151 is used to seal the first inlet portion 120 and the second sealing portion 152 is used to seal the second inlet portion 130.

[0025] The first sealing portion 151 and the second sealing portion 152 are arranged in a staggered manner both circumferentially and axially on the periphery of the valve core 150, so that only one of the first inlet portion 120 and the second inlet portion 130 is completely sealed by the valve core 150. For example, the communication relationship in the rotary valve 100 may include the following relationship: when the first sealing portion 151 seals the first inlet portion 120, the outlet portion 110 can communicate with the second inlet portion 130; when the second sealing portion 152 seals the second inlet portion 130, the outlet portion 110 can communicate with the first inlet portion 120; and when neither of the two inlets is completely sealed (as will be explained later), the outlet portion 110 can simultaneously communicate with both the first inlet portion 120 and the second inlet portion 130.

[0026] 6 to 9, in one embodiment of the present application, the angle difference between the first sealing portion 151 and the second sealing portion 152 in the circumferential direction of the peripheral surface of the valve core 150 is 60° to 120°, for example, the angle difference can be 90°. The valve core 150 simultaneously seals a partial area of ​​the connection port between the first inlet portion 120 and the main portion 141 and a partial area of ​​the connection port between the second inlet portion 130 and the main portion 141, allowing the liquid in the first inlet portion 120 and the liquid in the second inlet portion 130 to simultaneously flow into the valve body 140. In other words, by controlling the rotation angle of the valve core 150, the outlet portion 110 can simultaneously communicate with the first inlet portion 120 and the second inlet portion 130, allowing the user to control the liquid spray rate as needed.

[0027] For example, when the connection port between first inlet portion 120 and main portion 141 is 20% sealed by valve core 150 and the connection port between second inlet portion 130 and main portion 141 is 80% sealed by valve core 150, the liquid in first tank 210 (clean water) accounts for 80% of the liquid sprayed from the oral irrigator, and the liquid in second tank 220 (mouthwash) accounts for 20% of the liquid sprayed from the oral irrigator. Therefore, the liquid in second tank 220 can be filled with a high concentration of mouthwash, and by controlling the proportion of the liquid during use and diluting the mouthwash with clean water to a suitable concentration, the frequency of refilling the mouthwash in the second tank can be reduced, which is more suited to the user's usage requirements and improves customer adherence.

[0028] The valve core 150 can be rotated manually or can be controlled by a motor for passive rotation. By linking the motor controller with the application program on the user's mobile terminal, the user can define the liquid mixing ratio, and the valve core 150 will rotate by the corresponding angle following the motor to achieve the desired mixing ratio.

[0029] 8, in one embodiment of the present application, the first inlet port 120 and the second inlet port 130 are located at the bottom of the valve body 140. The design in which the first inlet port 120 and the second inlet port 130 are both located at the bottom facilitates installation of the rotary valve 100, for example, by simply inserting the valve vertically into the corresponding connection port of the tank, resulting in a simple structure and easy installation. The connection port of the outlet port 110 for connection to the water pipe 300 can be oriented upward for easy connection to the water pipe 300.

[0030] In one embodiment of the present application, referring to FIG. 8 , the inner chamber of the main part 141 may be cylindrical, and axial shoulders 153 are provided at both axial ends of the valve core 150, which abut against the inner wall surface of the main part 141 to make the axes of the valve core 150 and the main part 141 overlap, so that the sealing part can smoothly seal the corresponding inlet part.

[0031] In one embodiment of the present application, the first sealing portion 151 and the second sealing portion 152 may include or be silicone, but may also be made of other materials, such as other types of soft materials, as long as they are capable of performing the sealing function.

[0032] 7 and 8, in one embodiment of the present application, a handwheel 154 is connected to the end of the valve core 150. The handwheel 154 allows the valve core 150 to rotate, making it easier to control the flow and blocking of the corresponding liquid. A rotation angle limiting structure for the handwheel 154 can be installed at the handwheel 154. For example, the clockwise rotation limit of the handwheel 154 is set to completely seal the first inlet port 120, and the counterclockwise rotation limit is set to completely seal the second inlet port 130. The rotation angle limiting structure can include an arc-shaped track, in which the handwheel 154 is connected to the valve core via a connecting rod, and a moving block is installed on the connecting rod, and the moving block is installed within the track. The position of the moving block is limited via the arc-shaped track, thereby limiting the rotation angle of the handwheel 154.

[0033] 5, in one embodiment of the present application, the pump assembly 400 may include a pressure chamber 410, one end of which (e.g., an end at the top right of the pressure chamber 410 in the view of FIG. 5) is connected to the water conduit 300, and the liquid in the rotary valve 100 is introduced into the pressure chamber 410. The other end of the pressure chamber (e.g., an end at the top left of the pressure chamber 410 in the view of FIG. 5) is connected to a jet 500, and the liquid in the pressure chamber 410 is jetted out of the oral irrigator through the jet 500.

[0034] 5, in one embodiment of the present application, a first one-way valve 411 is installed between the water conduit 300 and the pressure chamber 410, and a second one-way valve 412 is installed between the pressure chamber 410 and the spout 500. The second one-way valve 412 can be a duckbill valve.

[0035] 3, in one embodiment of the present application, the dual tank oral irrigator can include a battery 610 and a motor 620. The battery 610 is connected to the motor 620, and the output shaft of the motor 620 is connected to the pump assembly 400 to achieve pumping of the liquid.

[0036] 5 , in one embodiment of the present application, the pump assembly 400 may include a gear shaft 420, an eccentric shaft sleeve 430, and a transmission rod 440. The eccentric shaft sleeve 430 is fixedly connected to the gear shaft 420, one end of the transmission rod 440 is fitted into the eccentric shaft sleeve 430, and the other end of the transmission rod is connected to a diaphragm 450, which forms one surface of the pressure chamber 410. The operation principle may be as follows: after the gear shaft 420 is driven by the motor 620, the eccentric shaft sleeve 430 rotates accordingly, and the transmission rod 440 and the eccentric shaft sleeve 430 form a cam mechanism, which causes the transmission rod 440 to reciprocate. When the transmission rod 440 moves upward, the liquid in the pressure chamber 410 is pumped out through the nozzle 500. When the transmission rod 440 moves downward, the liquid in the first tank 210 or the second tank 220 is pumped into the pressure chamber 410 .

[0037] Furthermore, the pump assembly 400 may include a transmission gear 460, and an output shaft of the motor 620 is connected to the transmission gear 460, and the transmission gear 460 meshes with a gear 421 of the gear shaft 420 to drive the rotation of the gear shaft 420. The transmission gear 460 and the gear 421 of the gear shaft 420 may be tapered gears, and their axes intersect with each other.

[0038] In one embodiment of the present application, referring to FIG. 4, a first liquid supply port 211 is provided on the side of the first tank 210, and a second liquid supply port 221 is provided on the side of the second tank 220, and the liquid corresponding to each tank can be replenished through each liquid supply port.

[0039] In one embodiment of the present application, referring to FIG. 4, the first tank 210 is located below the second tank 220 .

[0040] The above description is a preferred embodiment of the present application, but a person skilled in the art may make some improvements and modifications without departing from the principles of the present application, and these improvements and modifications should also be considered to be within the scope of protection of the present application.
