Description

Technical Field

[0001] The present invention relates to a dental cleaning device, and more specifically, to a collapsible dental irrigator. Background Art

[0002] Gingival sulcus and interdental spaces are two of the most difficult areas to clean. Some studies have pointed out that "up to 40% of the tooth surface cannot be cleaned with a toothbrush". Although dental floss (or toothpicks) can remove the deposits on the tooth surface, microscopically, the uneven tooth surface will still not be clean. According to research by relevant institutions in the United States, a pressurized water column can flush into the gingival sulcus to a depth of 50 - 90%. The pressurized water column can not only clean various gaps, holes and uneven surfaces, but also achieve a microscopic "cleaning" effect rather than just a macroscopic rough "removal".

[0003] Dental irrigators are a relatively new type of oral cleaning appliance. In Europe and the United States, dental irrigators are essential household hygiene products and have been widely used. The cleaning effect of dental irrigators is mainly achieved by the impact force of the high - speed water column ejected under a certain pressure. On the basis of mainly relying on the impact force of the water flow itself, the following measures may further improve the cleaning effect:

[0004] 1) Make the water flow eject and impact in an appropriate pulse form;

[0005] 2) Add some additives with different functions to the water flow, such as adding fine hard abrasive grains to form countless high - speed "bullets", or adding some surfactants that enhance the cleaning function, etc. The impact cleaning ability of the water column is also related to the size of the water column.

[0006] Existing dental irrigators consist of a power pump and a water tank. The power pump structure pumps the water in the water tank and sprays it onto the user's gums through a water column. When the user travels, since the water tank and the power pump structure of the dental irrigator occupy a large amount of space in the suitcase, it is not convenient for the user to carry. Summary of the Invention

[0007] The purpose of the present invention is to provide a collapsible dental irrigator. By opening an opening at the bottom of the water tank and putting the removed spray pipe and the holding part into the water tank, the overall volume of the dental irrigator is reduced, achieving the purpose of convenient carrying of the dental irrigator.

[0008] The above technical purpose of the present invention is achieved through the following technical solutions:

[0009] A collapsible dental irrigator, comprising a spray pipe, a holding part and a water tank arranged in sequence from top to bottom. The water tank, the holding part and the spray pipe are all detachable from each other. The bottom of the water tank is provided with a bottom cover that rotates outwards. The bottom cover is provided with a sealing ring that seals with the water tank, and a buckling component is arranged between the bottom cover and the side wall of the water tank;

[0010] An opening for placing the holding part and the water spraying pipe is provided at the bottom of the water tank, and the bottom cover seals the opening.

[0011] By adopting the above technical solution, the water spraying pipe can be inserted into the holding part and locked by rotation; after the holding part is stacked on the water tank, it can be rotationally engaged, and in this way, the disassembly and installation among the three can be realized.

[0012] When the dental cleaner is not in use, the opening at the bottom of the water tank, as a channel for placing the holding part and the water spraying pipe, realizes the purpose of accommodating the holding part and the water spraying pipe in the water tank, realizes the purpose of reducing the volume of the dental cleaner when carried, and is convenient for the user to carry out when going out. The sealing of the opening is realized by rotating and closing the bottom cover. When the water tank is filled with water, the sealing ring has a good water closing effect, so that the water tank will not leak; and the buckling component is for further locking the bottom cover and the water tank to prevent the bottom cover from being rotated and pushed away from the water tank by the gravity of water.

[0013] The second advantage of placing the holding part and the water spraying pipe at the position of the bottom cover in this design is that the free opening and closing of the bottom cover can facilitate the user to clean the stains on the bottom cover; it should be noted that after long-term use, there will be a large amount of stains at the bottom of the traditional water tank. However, since the volume of the water tank is large, it is difficult to clean the stains at the bottom with a brush. However, by adopting the way of freely rotating the bottom cover in this design, the bottom of the water tank can be very conveniently cleaned, and further, it is also convenient to clean the stains on the side wall of the water tank.

[0014] Preferably, the buckling component includes a buckle ring and a buckle lock. The buckle ring is placed on the outer wall of the water tank, and the buckle lock is placed on the bottom cover, and the buckle ring and the buckle lock are buckled.

[0015] By adopting the above technical solution, the structure of the buckle ring and the buckle lock makes the locking of the bottom cover and the water tank convenient, and the operation of putting the holding part and the water spraying pipe into the water tank is also more convenient, and further achieves the purpose of convenient carrying of the dental cleaner.

[0016] Preferably, a convex part is provided at the upper end of the holding part, the water spraying pipe is inserted into the convex part, a water inlet hole is opened at the upper part of the water tank, and the water inlet hose of the holding part extends into the water inlet hole;

[0017] When the holding part is placed in the water tank, the convex part of the holding part is inserted into the water inlet hole.

[0018] By adopting the above technical solution, the water inlet hole itself is for the water inlet hose to extend into the water tank; in this design, when the holding part is put into the water tank, the convex part is inserted into the water inlet hole, which can play a role of limiting and restraining, and can reduce the situation that the holding part swings freely in the water tank and impacts the side wall of the water tank, which is beneficial to reducing the probability of damage to the motor and the water pump in the holding part, thereby prolonging the service life of the dental cleaner.

[0019] Secondly, the raised portion blocks the water inlet hole, and the bottom cover blocks the bottom of the water tank. The interior of the water tank is equivalent to a closed space, which can ensure that the water tank is relatively clean, and the user is more hygienic when using the toothbrush of this design.

[0020] Preferably, the bottom cover is provided with two positioning posts, and the grip portion is provided with positioning holes for the positioning posts to be inserted into.

[0021] By adopting the above technical scheme, the insertion of the positioning column and the positioning hole can further fix the bottom cover and the gripping part. Obviously, with the insertion relationship between the protrusion and the socket, the water tank and the gripping part have a fixed relationship at three points. By utilizing the stability of the triangle, the gripping part can be stably fixed in the water tank. Even when the water tank falls to the ground, the gripping part will not collide with the side wall of the water tank, which is beneficial to reduce the probability of damage to the motor and water pump in the gripping part, thereby extending the service life of the toothbrush.

[0022] Preferably, the raised portion is provided with an insertion hole, and a freely disengageable elastic sealing sheet is placed in the insertion hole.

[0023] By adopting the above technical solution, the elastic sealing sheet can block the insertion hole, so that foreign objects cannot enter the gripping part, making the tooth washer more hygienic and clean; and the elastic sealing sheet is easy to remove.

[0024] Preferably, the bottom cover is provided with a rotating shaft, and the rotating shaft is rotatably connected to the water tank.

[0025] By adopting the above technical solution, due to the existence of the rotating shaft, the bottom cover can rotate more flexibly in the water tank.

[0026] Preferably, the bottom cover is fixed with an insertion rod for the water spray pipe to be inserted, and the insertion rod is arranged adjacent to the rotating shaft.

[0027] By adopting the above technical solution, the water spray pipe is inserted into the insertion rod, which can prevent the water spray pipe from shaking freely in the water tank.

[0028] The insertion rod is located near the rotating shaft to facilitate the water spray pipe to enter the water tank as the bottom cover rotates, so as to achieve the purpose of facilitating the water tank to retract the water spray pipe.

[0029] Preferably, the number of the insertion rods is two.

[0030] By adopting the above technical solution, two water spray pipes can be placed on the two insertion rods, so that relatives can borrow the teeth washer from each other.

[0031] Preferably, the cross section of the water tank gradually increases from top to bottom.

[0032] By adopting the above technical solution, the cross-sectional area of ​​the bottom of the water tank is large, which makes it easy for the grip to be inserted into the water tank.

[0033] Preferably, the capacity of the water tank is 250-300 ml.

[0034] By adopting the above technical solution, the water volume of 250-300 ml is relatively large, and the user does not need to add water to the water tank during the teeth cleaning process, making the teeth cleaning device of this design more convenient to use.

A buckle is fixed on the upper end of the water tank 3, and a block is fixed on the lower end of the gripping part 2. The block and the buckle can be rotated and fixed.

[0051] The cross-section of the water tank 3 gradually increases from top to bottom, and the capacity of the water tank 3 is 250-300 ml. The cross-sectional area of ​​the bottom of the water tank 3 is large, which makes it easy for the grip 2 to be loaded into the water tank 3; the water volume of 250-300 ml is large, and the user does not need to add water to the water tank 3 during teeth washing, making the tooth washer designed more convenient to use.

[0052] An opening 32 is provided at the bottom of the water tank 3. A bottom cover 31 that is screwed outward is provided at the bottom of the water tank 3. The bottom cover 31 covers the opening 32. The bottom cover 31 fixes the rotating shaft 8. A shaft sleeve is fixed to the side wall of the water tank 3. The rotating shaft 8 can be installed in the shaft sleeve and rotate, so the rotating shaft 8 is rotatably connected to the water tank 3. The bottom cover 31 is provided with a sealing ring 33 that is sealed with the water tank 3. When the bottom cover 31 is covered on the bottom of the water tank 3, the sealing of the opening 32 is achieved by rotating and closing the bottom cover 31. When the water tank 3 is filled with water, the sealing ring 33 has a good water-tightening effect, so that the water tank 3 will not leak.

[0053] like Figure 4 As shown, a snap-fit ​​assembly is provided between the bottom cover 31 and the side wall of the water tank 3, and the snap-fit ​​assembly includes a buckle 41 and a buckle lock 42. The buckle 41 is rotatably connected to the outer wall of the water tank 3, and the buckle lock 42 is placed on the bottom cover 31. The buckle lock 42 is inserted into the buckle 41 to achieve the buckling of the two.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, a protrusion 5 is provided at the upper end of the gripping portion 2, and a plug hole 6 is opened on the protrusion 5. A freely disengageable elastic sealing sheet 51 is placed in the plug hole 6. The elastic sealing sheet 51 is a silicone sheet, and the silicone sheet can be freely disengaged from the plug hole 6; when the water spray pipe 1 is inserted into the plug hole 6, the elastic sealing sheet 51 is taken out of the plug hole 6; when the water spray pipe 1 is in the water tank 3, the elastic sealing sheet 51 is placed in the plug hole 6 to avoid contamination of the plug hole 6.

[0055] like Figure 3 , Figure 4 ,Figure 5 and Figure 6 As shown in Figure 6 , a water inlet hole 34 is provided at the upper part of the water tank 3. The water inlet hose 21 of the holding part 2 extends into the water inlet hole 34, and the water inlet hose 21 can be twisted.

When the holding part 2 is placed in the water tank 3, the protruding part 5 of the holding part 2 is inserted into the water inlet hole 34 to block the water inlet hole 34, and then the bottom cover 31 is rotated to seal the water tank 3, realizing the insertion of the positioning post 71 and the positioning hole 72.

[0056] The bottom cover 31 is fixed with two insertion rods 9 for the water spray pipe 1 to be inserted. When the bottom cover 31 is opened, the water spray pipe 1 is inserted into the insertion rods 9. Then the bottom cover 31 is rotated towards the position of sealing the water tank 3. Since the insertion rods 9 are arranged adjacent to the rotating shaft 8, the water spray pipe 1 is screwed into the water tank 3, realizing the convenient storage of the water spray pipe 1 in the water tank 3.

[0057] Working principle:

[0058] When the dental cleaner is not in use, the opening 32 at the bottom of the water tank 3 serves as a channel for placing the holding part 2 and the water spray pipe 1, realizing the purpose of accommodating the holding part 2 and the water spray pipe 1 in the water tank 3, achieving the purpose of reducing the volume of the dental cleaner when carried, and facilitating the user to carry it out. The sealing of the opening 32 is realized by rotating the bottom cover 31 to close. When there is water in the water tank 3, the sealing ring 33 has a good water closing effect, so that the water tank 3 will not leak.

[0059] The second advantage of placing the holding part 2 and the water spray pipe 1 at the position of the bottom cover 31 in this design is that the free opening and closing of the bottom cover 31 can facilitate the user to clean the stains on the bottom cover 31. It should be noted that after long-term use, there will be a large amount of stains at the bottom of the traditional water tank 3. However, due to the large volume of the water tank 3, it is difficult to clean the stains at the bottom with a brush. However, by adopting the way of freely rotating the bottom cover 31 in this design, it is very convenient to clean the bottom of the water tank 3, and further it is also convenient to clean the stains on the side wall of the water tank 3.

[0060] The insertion of the positioning post 71 and the positioning hole 72 further fixes the bottom cover 31 and the holding part 2. Obviously, with the insertion relationship between the protruding part 5 and the insertion hole 6, there are three-point fixing relationships between the water tank 3 and the holding part 2. Using the stability of the triangle, the holding part 2 can be stably fixed in the water tank 3. Even when the water tank 3 falls to the ground, the holding part 2 will not collide with the side wall of the water tank 3, which is beneficial to reducing the probability of damage to the motor and the water pump in the holding part 2, thereby prolonging the service life of the dental cleaner.

[0061] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
