Description

Technical Field

[0001] This utility model relates to dental cleaning equipment. Background Technology

[0002] As people's living standards improve, they also pay more attention to oral health. Brushing teeth is currently the most common way to clean the mouth. However, toothbrushes cannot clean the tiny gaps between teeth, which can easily lead to plaque buildup and cause dental and gum diseases. Therefore, dental irrigators have emerged to clean teeth and gaps by using pulsed water jets to ensure oral health.

[0003] Commonly used dental irrigators include handheld, countertop, and wall-mounted models. Common countertop or wall-mounted models typically have a large water tank and a handheld handle. The water tank contains a water pump, and the handle is connected to the pump via a 100cm hose. During operation, the pump draws water from the tank and sprays it from the nozzle on the handle. However, the long hose increases the flow path, reducing the force of the water jet and affecting the cleaning effect. Furthermore, existing dental irrigators often spray cold water, which can irritate teeth in winter, resulting in a poor user experience. Additionally, residual water after use can easily breed bacteria, contaminating the sprayed water. Utility Model Content

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] like Figures 1 to 5 As shown, a dental cleaning device according to this embodiment includes a water tank 1, a spray pump module 2, a sterilization module 3, a heating module 4, a water inlet pipe 5, and a handheld water outlet component 6.

[0020] The water tank 1 is provided with a water storage chamber 11 and an equipment chamber 12. The heating module 4 is located in the equipment chamber 12, and the sterilization module 3 and the spray pump module 2 are located in the handheld water outlet assembly 6. The handheld water outlet assembly 6 is detachably located on the side of the water tank 1. The heating module 4 is an instant heating device. The internal structure of the heating module 4 is not shown in the diagram. Figure 5 and Figure 6 As shown, the water inlet 41 of the heating module is electrically connected to the water storage chamber 11, the water outlet 42 of the heating module is connected to one end of the water inlet pipe 5, the other end of the water inlet pipe 5 is connected to the water inlet 302 of the sterilization module in the handheld water outlet assembly 6, the water outlet 301 of the sterilization module is electrically connected to the water inlet 202 of the spray pump module, and the water outlet 201 of the spray pump module is electrically connected to the water nozzle 7 installed on the handheld water outlet assembly 6.

[0021] Therefore, the dental cleaning device can be used as both a wall-mounted and countertop device. In this embodiment, the handheld water outlet assembly 6 is still connected to the water tank 1 via the water inlet pipe 5. However, the spray pump module 2 for spraying water is located inside the handheld water outlet assembly 6 and directly connected to the water nozzle 7, which can effectively improve the water jet force of the water nozzle 7 and provide a better impact cleaning effect. In addition, a heating module 4 is also provided between the water storage chamber 11 in the water tank 1 and the water inlet pipe 5, which can quickly heat the water pumped from the water storage chamber 11, ensuring that the water pumped from the water nozzle 7 is at a suitable temperature, avoiding irritation to the oral cavity, teeth, and gums, and improving the user experience. At the same time, the handheld water outlet assembly 6 also has a sterilization module 3 located between the water inlet pipe 5 and the spray pump module 2, which can sterilize and disinfect the water to be sprayed, ensuring that the cleaning water is clean and hygienic, avoiding oral infections and improving product safety.

[0022] Of course, the dental cleaning device may also include a water pump 10, which is disposed inside the device cavity 12 and connected between the water outlet 42 of the heating module and the water inlet pipe 5. This can further increase the impact force of the pumped water.

[0023] like Figure 4 and Figure 6 As shown, in this embodiment, the handheld water outlet assembly 6 includes a water flosser housing 61, a water nozzle 7 detachably mounted on the top of the water flosser housing 61, and a sterilization module 3 and a spray pump module 2 installed inside the water flosser housing 61; the other end of the water inlet pipe 5 is connected to the bottom of the water flosser housing 61.

[0024] The oral irrigator housing 61 may have a cavity 611 inside, a base plate 62 is installed at the bottom of the cavity 611, the sterilization module 3 and the spray pump module 2 can be installed in the cavity 611, and the water nozzle 7 can be installed on the top of the oral irrigator housing 61.

[0025] In this embodiment, the side of the water tank 1 is recessed with a trough 13 for accommodating the handheld water dispensing component 6. The trough 13 has a placement plate 131 for placing the handheld water dispensing component 6, and the water dispensing pipe 5 is accommodated below the placement plate 131. This allows for convenient and quick removal and placement of the handheld water dispensing component 6 from the water tank 1.

[0026] The water inlet pipe 5 can be a spring-loaded fitting, which allows it to be moved and pulled away freely when the handheld water outlet component 6 is removed, and can quickly return to its original position when put back, making it easy to store.

[0027] See Figure 4 and Figure 7 In this embodiment, the sterilization module 3 includes a shell 31, a control motherboard 32, a light-proof barrier sleeve 33, and a transparent flow-through inner tube 34.

[0028] The transparent inner tube 34 can be a long tube extending vertically. One end of the transparent inner tube 34 can serve as the water inlet 302 of the sterilization module, and can be connected to one end of the water inlet pipe 5 through the lower sealing connector 35. The other end of the water inlet pipe 5 is connected to the heating module 4. The other end of the transparent inner tube 34 can serve as the water outlet 301 of the sterilization module, and can be connected to one end of an adapter 8 through the upper sealing connector 36. The other end of the adapter 8 is connected to the water inlet 202 of the spray pump module.

[0029] The light-proof barrier sleeve 33 is fitted around the outer periphery of the transparent flow inner tube 34, and the outer shell 31 is fitted around the outer periphery of the light-proof barrier sleeve 33. The control main board 32 is mounted on the outer shell 31, and the control main board 32 is equipped with a germicidal lamp 321. The light-proof barrier sleeve 33 is provided with a light-transmitting area 331 corresponding to the germicidal lamp 321, so that the germicidal lamp 321 can sterilize and disinfect the water in the transparent flow inner tube 34 through the light-transmitting area 331.

[0030] Since the transparent flow-through inner tube 34 is located between the water inlet pipe 5 and the spray pump module 2, when the fluid in the water storage chamber 11 is drawn into the transparent flow-through inner tube 34 through the heating module 4 and the water inlet pipe 5, it can be instantly and quickly sterilized by the irradiation of the germicidal lamp 321. Moreover, the light-proof barrier sleeve 33 covers the outer periphery of the transparent flow-through inner tube 34, which can prevent the scattering of the sterilizing light and make the sterilization effect better.

[0031] Of course, the sterilization module 3 can also be equipped with only a transparent flow inner tube 34, a control motherboard 32, and a sterilization lamp 321, which can also achieve the sterilization effect.

[0032] The transparent inner tube 34 can be a long tube, therefore, multiple germicidal lamps 321 can be spaced apart along the axial direction of the transparent inner tube 34. Thus, even with a high water flow rate, longer sterilization time can be achieved, resulting in better cleaning. This embodiment uses two lamps as an example, and dual-wavelength UV germicidal lamps 321 can be used for better sterilization and to kill specific bacteria. Of course, the germicidal lamp 321 can also be a single-wavelength lamp.

[0033] Specifically, a mounting groove 311 for mounting the control motherboard 32 can be provided on one side of the outer shell 31. The mounting groove 311 has a lamp hole 312 that connects to the inner cavity 313 of the outer shell. The lamp hole 312 is for the germicidal lamp 321 to pass through. The light-proof barrier sleeve 33 is installed in the inner cavity 313 of the outer shell. The light-transmitting area 331 of the light-proof barrier sleeve 33 can be a through hole that connects the inside and outside of the light-proof barrier sleeve 33. The through hole allows the germicidal lamp 321 to pass through, so that the germicidal light can irradiate the transparent flow inner tube 34. The transparent flow inner tube 34 is installed inside the light-proof barrier sleeve 33. The transparent flow inner tube 34 can be a high-temperature resistant glass tube to accommodate heated water.

[0034] In this embodiment, by setting the outer shell 31 to wrap the transparent flow-through inner tube 34 and the light-proof barrier sleeve 33, the control motherboard 32 and the water-passing transparent flow-through inner tube 34 can be separated, which can improve the safety of use, prevent the control motherboard 32 from being damaged due to water leakage from the transparent flow-through inner tube 34, and improve the reliability of product use.

[0035] The top of the outer shell 31 has an upper opening 314 that connects to the inner cavity 313 of the outer shell. The bottom of the inner cavity 313 forms a snap-fit ​​step 315. The transparent flow-through inner tube 34 and the light-proof barrier sleeve 33 can be inserted into the inner cavity 313 of the outer shell from top to bottom through the upper opening 314. The lower ends of the transparent flow-through inner tube 34 and the light-proof barrier sleeve 33 abut against the lower sealing connector 35 and snap onto the snap-fit ​​step 315. The middle of the snap-fit ​​step 315 has a lower hole 316 in the outer shell that connects to the outside, which facilitates product assembly. The transparent flow-through inner tube 34 can be connected to the water inlet pipe 5 through the lower sealing connector 35 from the lower hole 316 in the outer shell.

[0036] The outer casing 31 may be provided with two snap-fit ​​seats 318 with snap-fit ​​grooves 317 on the side at the opening 314. The adapter 8 may be an inverted "L" shaped adapter 8. The bottom opening of the adapter 8 may be provided with two snap-fit ​​blocks 81, and can be quickly snapped into the opening 314 of the outer casing 31 by the rotational cooperation of the two snap-fit ​​blocks 81 and the snap-fit ​​grooves 317. The upper sealing joint 36 may be provided between the upper opening 314 and the adapter 8 to seal the connection between the adapter 8 and the upper opening 314.

[0037] In this embodiment, the sterilization module 3 can be arranged side by side with the spray pump module 2, and the right opening of the adapter 8 can be connected to the water inlet 302 of the sterilization module 32.

[0038] A one-way valve 9 may also be installed at the right opening of the adapter 8, so that the water from the sterilization module 3 can flow into the spray pump module 2 in one direction, preventing the liquid from flowing back from the water nozzle 7. In this embodiment, the one-way valve 9 includes a one-way piston 91 and a piston spring 92.

[0039] like Figure 4 and Figure 8 As shown, the spray pump module 2 in this embodiment may include a housing 21, a spray pump 22, a motor 23, a dental cleaning control board 24, and a battery 25. The spray pump 22 and the motor 23 are installed inside the housing 21. The motor 23 drives the spray pump 22 to operate. The water inlet of the spray pump 22 (i.e., the water inlet 202 of the spray pump module) is connected to the right opening of the adapter 8, and the water outlet of the spray pump 22 (i.e., the water outlet 201 of the spray pump module) is connected to the water nozzle 7. The battery 25 and the dental cleaning control board 24 are respectively installed on both sides of the housing 21, and both the motor 23 and the battery 25 are electrically connected to the dental cleaning control board 24. The battery 25 is used to supply power to the motor 23, and the dental cleaning control board 24 is used to control the operation of the motor 23.

[0040] The aforementioned control board 32 can also be electrically connected to the dental cleaning control board 24, and the operation of the germicidal lamp 321 can be controlled through the dental cleaning control board 24.

[0041] See Figure 2 The inner surface of the handheld water dispensing component 6 may be provided with a wireless charging module 63, which is electrically connected to the battery 25; the inside of the side wall of the container 13 on the side of the water tank 1 may be provided with a wireless charging component 132. When the handheld water dispensing component 6 is stored in the container 13, the wireless charging component 132 is used to wirelessly charge the battery 25.

[0042] Both the wireless charging module 63 and the wireless charging component 132 can be charging coils.

[0043] like Figure 2 As shown, the water tank 1 in this embodiment is further provided with a water tap disinfection chamber 14. The top of the water tap disinfection chamber 14 is provided with a removable chamber cover 141. Inside the water tap disinfection chamber 14, there is a retaining plate 142. The retaining plate 142 is provided with several retaining holes 143 for holding the water taps 7. A disinfection lamp (not shown in the figure) is provided below the retaining plate 142. This is to facilitate the storage and disinfection of the used water taps 7. The disinfection lamp can also be a dual-wavelength UV germicidal lamp, etc.
