Description

TECHNICAL FIELD

[0001] The utility model relates to oral irrigator technical field, concretely is oral irrigator water pipe with filter component. BACKGROUND

[0002] With the improvement of living standards, people's consciousness of oral care gradually improves, and oral cleaning tools on the market are more and more various, wherein, oral irrigator as the substitute of traditional dental floss becomes one of the household small household appliances. Its basic working principle is to use the pump body to pump water from the water tank, and the high-pressure pulse water flow of several hundred times per minute or even thousands of times is sprayed out through the nozzle to clean food residues, dental plaque and massage teeth in the tooth gap, and improve the oral environment.

[0003] However, the water pipe of the existing oral irrigator does not have a filtering function, so that when the oral irrigator is used, impurities in the water will be sprayed out from the nozzle together with the water pipe and the pump head, thereby causing poor washing effect of the oral irrigator on the teeth.

[0004] To solve the above problems, the present application provides an oral irrigator water pipe with a filter component. CONTENT OF THE UTILITY MODEL

[0005] The utility model intends to provide an oral irrigator water pipe with a filter component, mainly used to solve the problem that the water pipe of the existing oral irrigator does not have a filtering function, so that when the oral irrigator is used, impurities in the water will be sprayed out from the nozzle together with the water pipe and the pump head, thereby causing poor washing effect of the oral irrigator on the teeth.

[0006] To solve the above technical problems, the utility model provides the following technical scheme:

[0007] An oral irrigator water pipe with a filter component, comprising a water storage tank, a pump head threadedly connected to the top of the water storage tank, a nozzle fixedly connected to the top of the pump head, a water delivery pipe fixedly connected to the bottom of the pump head, an upper shell fixedly connected to the lower end of the water delivery pipe, the inside of the water delivery pipe and the upper shell being in communication, a lower shell connected to the bottom of the upper shell, a through hole formed in the upper shell, an annular block fixedly connected to the top of the lower shell, an annular groove formed in the bottom of the outer wall of the upper shell and matched with the annular block, a limiting assembly arranged on the inner wall of the annular groove, a spherical filter screen connected between the upper shell and the lower shell, and the inner wall of the upper shell and the lower shell being in abutment with the spherical filter screen.

[0008] The working principle and advantages of the utility model are as follows:

[0009] 1. Working Principle: When using the oral irrigator, add the cleaning solution into the water tank, then fix the pump head to the water tank with threads. Start the pump head, and the cleaning solution inside the water tank will enter the upper and lower housings through the through hole on the lower housing. The spherical filter screen set between the upper and lower housings can effectively filter the cleaning solution. After filtration, the cleaning solution is transported to the pump head through the water pipe and then sprayed out from the nozzle to rinse the patient's teeth. If the spherical filter screen becomes clogged after prolonged use, remove the pump head, release the limiting component on the annular groove to remove the lower housing, and then replace the spherical filter screen. After replacement, fix the lower housing to the bottom of the upper housing with the limiting component, and the oral irrigator can be used normally.

[0010] 2. Beneficial Effects: When using this oral irrigator, the upper and lower housings are located at the lower end of the water supply pipe. A spherical filter screen is installed between the upper and lower housings. The spherical filter screen can effectively filter the cleaning solution, thus providing a better rinsing effect on the patient's teeth. The upper and lower housings are fixedly connected by a limiting component, which makes it easy to disassemble and assemble the lower housing. This facilitates the replacement of the spherical filter screen, effectively preventing the spherical filter screen from becoming clogged and causing the oral irrigator to malfunction, thereby effectively extending the service life of the oral irrigator.

[0011] Preferably, the limiting component includes a sliding cavity formed in the inner wall of the annular groove, and the sliding cavities are symmetrically arranged on the inner wall of the annular groove. A wedge block is slidably connected inside the sliding cavity. One side of the wedge block extends out of the sliding cavity, and an elastic sheet is fixedly connected to the other side. One end of the elastic sheet is fixedly connected to the inner wall of the sliding cavity, and the other end is slidably connected to the sliding cavity. A limiting groove matching the wedge block is formed on the annular block, and a button is slidably connected inside the limiting groove. One side of the button extends out of the annular block, and the other side abuts against the wedge block. Pressing both buttons on the annular block simultaneously can push the wedge block to slide into the sliding cavity. Squeeze the elastic plate until the wedge block disengages from the limiting groove on the annular block, then the lower housing can be removed. The spherical filter can then be replaced. After replacement, insert the annular block on the lower housing into the annular groove at the bottom of the upper housing. The inside of the annular block will squeeze the wedge block, causing it to slide into the sliding cavity. When the annular block is fully inside the annular groove, the wedge block will pop out under the action of the elastic plate and engage with the limiting groove, thus fixing the lower housing to the bottom of the upper housing. The flosser can then be used normally. The advantage of this design is that it makes it convenient for people to replace the spherical filter.

[0012] Preferably, symmetrical positioning blocks are fixedly connected to the inner wall of the annular block, and positioning grooves matching the positioning blocks are opened on the inner wall of the annular groove. When installing the lower housing, the positioning blocks on the inner wall of the annular block should be aligned with the positioning grooves inside the annular groove first. This can play a better positioning role for the lower housing, making the installation of the lower housing more convenient.

[0013] Preferably, a sealing ring is fixedly connected to the top of the inner wall of the upper housing and the top of the upper housing, and the sealing ring is set against the outer wall of the spherical filter screen. Since the rubber material has good sealing performance, the sealing ring set at the top of the inner wall of the upper housing can effectively prevent the cleaning liquid inside the water storage tank from being discharged through the water supply pipe without being filtered by the spherical filter screen, thus achieving a better filtration effect for the cleaning liquid.

[0014] Preferably, sliders are fixedly connected to both sides of the button, and the inner wall of the limiting groove is provided with a sliding groove that matches the slider. When the button slides inside the limiting groove, the sliders on both sides of the button and the sliding groove on the inner wall of the limiting groove can play a good limiting and guiding role for the button. This not only makes the button more stable when sliding inside the limiting groove, but also effectively prevents the button from leaving the inside of the limiting groove.

[0015] Preferably, there are multiple through holes, and the through holes are distributed in an array at equal intervals on the lower shell. By setting the number of through holes on the lower shell to multiple, the cleaning fluid inside the water tank can enter the upper and lower shells more efficiently through the through holes.

[0016] Preferably, all corners at the bottom of the positioning groove are chamfered. By chamfering all corners at the bottom of the positioning groove, it is easier to insert the positioning block into the positioning groove, thereby making the installation of the lower housing easier.

[0023] 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.

[0024] Please see Figures 1-5A water hose for a dental irrigator with a filter assembly includes a water tank 1. A pump head 2 is threadedly connected to the top of the water tank 1, and a nozzle 3 is fixedly connected to the top of the pump head 2. A water supply pipe 4 is fixedly connected to the bottom of the pump head 2, and an upper housing 5 is fixedly connected to the lower end of the water supply pipe 4. The water supply pipe 4 communicates with the interior of the upper housing 5. A lower housing 6 is connected to the bottom of the upper housing 5, and the lower housing 6 has multiple through holes 7. When using the dental irrigator, cleaning fluid is added to the water tank 1, and then the pump head 2 is threadedly fixed to the water tank 1. The pump head 2 is then activated, and the water inside the water tank 1 is cleaned. The liquid enters the space between the upper housing 5 and the lower housing 6 through the through hole 7 on the lower housing 6. An annular block 9 is fixedly connected to the top of the lower housing 6. An annular groove 8 matching the annular block 9 is formed on the bottom of the outer wall of the upper housing 5. Symmetrical positioning blocks 17 are fixedly connected to the inner wall of the annular block 9. Positioning grooves 18 matching the positioning blocks 17 are formed on the inner wall of the annular groove 8. When installing the lower housing 6, the positioning blocks 17 on the inner wall of the annular block 9 must first be aligned with the positioning grooves 18 inside the annular groove 8. This provides better positioning for the lower housing 6, making its installation easier. For convenience, the corners at the bottom of the positioning groove 18 are all chamfered, which makes it easier to insert the positioning block 17 into the positioning groove 18, thus making the installation of the lower housing 6 easier. The inner wall of the annular groove 8 is provided with a limiting component. A spherical filter screen 10 is connected between the upper housing 5 and the lower housing 6. The spherical filter screen 10 between the upper housing 5 and the lower housing 6 can achieve a good filtration effect on the cleaning fluid. After filtration, the cleaning fluid is transported to the pump head 2 through the water pipe 4, and then sprayed out by the nozzle 3 to rinse the patient's teeth. The upper housing 5 and the lower housing The lower housing 6 is fixedly connected by a limiting component, which makes it easier to disassemble and assemble the lower housing 6, thus facilitating the replacement of the spherical filter screen 10. The top of the inner wall of the upper housing 5 is fixedly connected with a sealing ring 16, and the sealing ring 16 is set against the outer wall of the spherical filter screen 10. Since the rubber material has good sealing properties, the sealing ring 16 set on the top of the inner wall of the upper housing 5 can effectively prevent the cleaning liquid inside the water storage tank 1 from being discharged through the water supply pipe 4 without being filtered by the spherical filter screen 10, thus achieving a better filtration effect for the cleaning liquid.

[0025] like Figure 2 , Figure 3 and Figure 5As shown, the limiting component includes a sliding cavity 11 formed in the inner wall of the annular groove 8, and the sliding cavities 11 are symmetrically arranged on the inner wall of the annular groove 8. A wedge block 12 is slidably connected inside the sliding cavity 11. One side of the wedge block 12 extends out of the sliding cavity 11, and an elastic sheet 13 is fixedly connected to the other side. One end of the elastic sheet 13 is fixedly connected to the inner wall of the sliding cavity 11, and the other end is slidably connected to the sliding cavity 11. A limiting groove 14 matching the wedge block 12 is formed on the annular block 9. A button 15 is slidably connected inside the limiting groove 14. Slider blocks 19 are fixedly connected to both sides of the button 15. A sliding groove 20 matching the slider 19 is formed in the inner wall of the limiting groove 14. One side of the button 15 extends out of the annular block 9, and the other side abuts against the wedge block 12. Pressing the annular block 9 simultaneously... The two buttons 15 can push the wedge block 12 into the sliding cavity 11, while squeezing the elastic plate 13. When the wedge block 12 disengages from the limiting groove 14 on the annular block 9, the lower housing 6 can be removed, and the spherical filter screen 10 can be replaced. After replacement, the annular block 9 on the lower housing 6 is inserted into the annular groove 8 at the bottom of the upper housing 5. The inside of the annular block 9 will squeeze the wedge block 12, causing it to slide into the sliding cavity 11. When the annular block 9 is fully inserted into the annular groove 8, the wedge block 12 will pop out under the action of the elastic plate 13 and engage with the limiting groove 14, thus fixing the lower housing 6 to the bottom of the upper housing 5. The water flosser can then be used normally. The advantage of this design is that it makes it convenient for people to replace the spherical filter screen 10.

[0026] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0027] When using the oral irrigator, add the cleaning solution into the water tank 1, then fix the pump head 2 to the water tank 1 with threads. Start the pump head 2, and the cleaning solution inside the water tank 1 will enter the space between the upper housing 5 and the lower housing 6 through the through hole 7 on the lower housing 6. The spherical filter 10 installed between the upper housing 5 and the lower housing 6 effectively filters the cleaning solution. After filtration, the cleaning solution is transported to the pump head 2 through the water pipe 4, and then sprayed out from the nozzle 3 to rinse the patient's teeth. If the spherical filter 10 becomes clogged after prolonged use, remove the pump head 2 and simultaneously press the two buttons on the ring block 9. 15 can push the wedge block 12 into the sliding cavity 11 and squeeze the elastic sheet 13 at the same time. When the wedge block 12 is disengaged from the limiting groove 14 on the annular block 9, the lower housing 6 can be removed and the spherical filter screen 10 can be replaced. After the replacement is completed, insert the annular block 9 on the lower housing 6 into the annular groove 8 at the bottom of the upper housing 5. The inside of the annular block 9 will squeeze the wedge block 12 to slide into the sliding cavity 11. When the annular block 9 is fully inserted into the annular groove 8, the wedge block 12 will pop out under the action of the elastic sheet 13 and engage with the limiting groove 14, thus fixing the lower housing 6 to the bottom of the upper housing 5. The oral irrigator can then be used normally.
