Technical Field

[0001] The utility model belongs to the technical field of irrigators, and in particular relates to an oral irrigator. Background Art

[0002] The existing oral irrigator includes a water tank, a liquid pump and a nozzle. The rinsing liquid in the water tank is pumped out by the liquid pump, and then the liquid is sprayed out from the nozzle to rinse the oral cavity. The rinsing liquid is usually clean water or a mixed solution of clean water and a rinsing agent. When in use, clean water and the rinsing agent are added to the water tank, and then the water tank is shaken to form a mixed liquid. The existing shaking and mixing process is often performed manually, which is troublesome to operate, and frequent shaking may loosen the internal parts of the irrigator, resulting in a reduced service life.

[0010] Preferably, a first spring is fixedly connected between the baffle plate and the fixed plate, and the first spring is sleeved on the outside of the slide rod.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) The utility model is provided with a two-position three-way solenoid valve and an air pump. When a mixture of clean water and a flushing agent is used to flush the oral cavity, the clean water and the flushing agent are added into the water tank respectively, the nozzle and the air pump are connected through the two-position three-way solenoid valve, and then the air pump is started to pass external ventilation into the liquid in the water tank through the nozzle, the air pump and the air pipe in sequence. The clean water and the flushing agent are automatically mixed through gas stirring. The operation is simple, and there is no need to shake the flusher, thereby increasing the service life.

[0013] (2) The utility model is provided with a clamping block and a pushing block. When the nozzle is disassembled, the pushing block slides along the slide rod close to the nozzle, so that the pushing block pushes the two clamping blocks to move to both sides, so that the clamping blocks are disengaged from the clamping slot. At this time, the nozzle can be easily pulled out from the top; when the nozzle is installed, the nozzle is inserted between the two clamping blocks from the top of the housing. The conical inclined surface at the bottom of the nozzle pushes the two clamping blocks to move to both sides along the guide rod and compresses the second spring. At the same time, the nozzle continues to move downward until the clamping slot on the nozzle moves to the clamping block. Based on the elastic force of the second spring, the clamping block is matched in the clamping slot to fix the nozzle. In this way, the nozzle can be quickly disassembled and installed by the clamping block and the pushing block, and the operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 5 As shown, the utility model provides the following technical solutions:

[0022] An oral irrigator comprises a housing 1 and a water tank 5 fixed to the bottom of the housing 1, a nozzle 2 is detachably connected to the top of the housing 1, a liquid pump 16, an air pump 15 and a two-position three-way solenoid valve 14 are fixedly arranged in the housing 1, the nozzle 2 is respectively connected to the liquid pump 16 and the air pump 15 through the two-position three-way solenoid valve 14, a liquid infusion pipe 18 and an air infusion pipe 17 are respectively connected between the liquid pump 16 and the air pump 15 and the water tank 5, and the liquid infusion pipe 18 and the air infusion pipe 17 both extend to the bottom of the water tank 5;

[0023] A water inlet is provided on one side of the water tank 5, and a sealing cover 4 for sealing the water inlet is rotatably connected to one side of the housing 1.

[0024] Based on the above disclosed structure, when using the irrigator to rinse the oral cavity:

[0025] First, install the nozzle 2 on the housing 1, then add clean water and flushing agent into the water tank 5 through the water inlet on one side of the water tank 5, and then energize the two-position three-way solenoid valve 14 to make it in the right position (such as Figure 5 As shown), at this time, the air pump 15 is connected with the nozzle 2, and the air pump 15 is started to make the external air pass through the nozzle 2, the air pump 15 and the air pipe 17 in sequence, and finally enter the water tank 5, and the outlet end of the air pipe 17 is located at the bottom of the water tank 5, so that the air forms bubbles and floats in the liquid, and at the same time, the bubbles play a role in stirring the liquid, so that the clean water and the flushing agent can be quickly mixed;

[0026] After the mixing is completed, the sealing cover 4 is rotated to seal the water inlet of the water tank 5 to prevent the mixed liquid from spilling during use;

[0027] Then, the two-position three-way solenoid valve 14 is energized to the left position (such as Figure 5 As shown), at this time, the nozzle 2 is connected to the liquid pump 16, and the liquid pump 16 is started, so that the mixed liquid of the clean water and the flushing agent in the water tank 5 passes through the infusion tube 18, the liquid pump 16 and the nozzle 2 in turn, and is finally sprayed into the oral cavity from the nozzle outlet of the nozzle 2, thereby achieving flushing of the oral cavity.

[0028] As mentioned above, regarding the installation of the nozzle 2, it is preferably set to the following structure:

[0029] Two clamping blocks 7 are symmetrically and slidably connected in the housing 1, and a second spring 19 is fixedly connected between the side surfaces of the two clamping blocks 7 and the inner wall of the housing 1. A clamping groove 8 matching with the clamping blocks 7 is provided on the nozzle 2, and a conical inclined surface is provided at the bottom of the nozzle 2;

[0030] Two guide rods 6 are fixedly installed in the housing 1 , and two clamping blocks 7 are slidably connected to the outsides of the two guide rods 6 . The second spring 19 is sleeved on the guide rods 6 .

[0031] As can be seen from the above, the bottom of the nozzle 2 is inserted into the casing so that the conical inclined surface at the bottom of the nozzle 2 corresponds to the hole between the two blocks 7. During the downward movement of the nozzle 2, the conical inclined surface of the nozzle 2 pushes the block 7 to move to both sides along the guide rod 6. At the same time, the block 7 and the inner wall of the casing 1 compress the second spring 19, and the nozzle 2 continues to move downward until the slot 8 on the nozzle 2 moves between the two blocks 7. At this time, based on the elastic force of the second spring 19, the two blocks 7 approach each other and slide into the slot 8, so that the two blocks 7 fix the nozzle 2 to prevent the nozzle 2 from moving up and down and falling off during the flushing process, thereby realizing the installation of the nozzle 2. The operation process is simple and the installation speed is fast.

[0032] In addition, after the nozzle 2 is used or when a different nozzle 2 needs to be replaced, the disassembly of the nozzle 2 is preferably set as follows:

[0033] The top of the housing 1 is slidably connected with a slider 3, a fixed plate 10 is fixed inside the housing 1, a slide bar 11 is slidably penetrated on the fixed plate 10, both ends of the slide bar 11 are respectively fixedly connected with a push block 9 and a baffle 13, the bottom of the slider 3 is fixedly connected with the baffle 13, and the ends of the two clamping blocks 7 are provided with inclined surfaces that slide with the push block 9;

[0034] A first spring 12 is fixedly connected between the baffle plate 13 and the fixing plate 10 , and the first spring 12 is sleeved on the outside of the sliding rod 11 .

[0035] As can be seen from the above, the slider 3 is slid toward the direction close to the nozzle 2 at the top of the housing 1, and the slider 3 drives the baffle 13 to approach the nozzle 2, so that the slide bar 11 slides on the fixed plate 10, and at the same time, the baffle 13 and the fixed plate 10 compress the first spring 12, and the slide bar 11 drives the push block 9 to approach the two clamping blocks 7, and the ends of the push block 9 and the inclined surfaces of the ends of the clamping blocks 7 slide and cooperate, so that the two clamping blocks 7 move to both sides along the guide rod and compress the second spring 19, so that the clamping block 7 is separated from the clamping groove 8 on the nozzle 2, and the nozzle 2 can be easily pulled out from the top of the frame 1 at this time, so as to complete the disassembly of the nozzle 2, which is simple to operate and fast to disassemble;

[0036] After disassembly is completed, the slider 3 is released. Based on the elastic force of the first spring 12 and the second spring 19, the first spring 12 allows the baffle 13 to drive the slide rod 11 and the push block 9 away from the block 7, and the second spring 19 allows the two blocks 7 to move closer to each other, thereby achieving the resetting of the two blocks 7, which is convenient for the next installation of the nozzle 2.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
