Description

Technical Field

[0001] The utility model belongs to the technical field of tooth washer, and in particular relates to a tooth washer with a nozzle that is convenient for replacing. Background Art

[0002] The tooth rinser, also known as the water flosser, is a relatively new oral cleaning device and is currently widely used.

[0003] The nozzle of the toothbrush needs to be replaced when it is used, but the nozzles of the toothbrush in the prior art are mostly fixed on the toothbrush by a threaded connection method. This method has certain disadvantages when operating. For example, it is not easy to rotate when the nozzle is wet and it is easy to slip. When the rotation is too firm, it is not convenient to disassemble and replace. In addition, some straight-plug nozzles are prone to water leakage, and the contact between the nozzle and the rubber block is not tight and it is easy to fall off.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies.

[0005] Therefore, in order to solve the above problems, the utility model provides a tooth washer that is easy to replace the nozzle. Utility Model Content

[0006] In order to overcome the above-mentioned technical problems, the purpose of the utility model is to provide a tooth washer that is easy to replace the nozzle. When installing the nozzle, align the insertion rod with the slot, and then press down the nozzle so that the insertion rod is inserted into the inside of the slot, and then insert one end of the pull rod into the positioning hole on the insertion rod to achieve the positioning of the insertion rod. This method is simple to operate and is convenient and quick.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A tooth washer that is easy to replace the nozzle, comprising a shell, a slot is provided on the shell, a nozzle is installed on the top of the shell, a nozzle is installed on the outside of the nozzle, a fixing ring is fixedly installed on the nozzle, plug rods are provided on both sides of the fixing ring, and positioning holes are provided on the plug rods. Pull rods are slidably connected to both sides of the shell, and one end of the pull rod is plug-connected to the positioning hole. When installing the nozzle, the plug rod is aligned with the slot, and then the nozzle is pressed down to insert the plug rod into the inside of the slot, and then one end of the pull rod is inserted into the positioning hole on the plug rod, thereby realizing the positioning of the plug rod. This method is simple to operate and convenient and quick.

[0009] Furthermore, a transverse groove is provided inside the shell, and the slot is communicated with the transverse groove.

[0010] Furthermore, an inner cavity is provided inside the shell, a delivery pipe is connected to the inner cavity, and one end of the delivery pipe is connected to the nozzle.

[0011] Furthermore, a water-absorbing expansion strip is installed between the spray head and the nozzle.

[0012] Furthermore, both sides of the fixing ring are fixedly connected with connecting blocks, and one side of the connecting block is fixedly installed with the insert rod.

[0013] Furthermore, a slide plate is fixedly mounted on the pull rod, a spring is connected to one side of the slide plate, the spring is sleeve-connected to the pull rod, and a handle is fixedly mounted on one end of the pull rod.

[0014] Furthermore, the slide plate and the spring are both arranged inside the transverse groove, and the slide plate is slidably connected to the inside of the transverse groove.

[0015] Furthermore, the bottom end of the insertion rod is arranged in a wedge shape, and one end of the pull rod is also arranged in a wedge shape.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the utility model, when installing the nozzle, the insertion rod is aligned with the slot, and then the nozzle is pressed down so that the insertion rod is inserted into the interior of the slot. When the insertion rod descends, the pull rod will be squeezed to move the pull rod outward. At this time, the spring is in a compressed state. When the insertion rod descends to the lowest end of the slot, the positioning hole can be aligned with the pull rod, and then through the action of the spring restoring force, one end of the pull rod is inserted into the positioning hole on the insertion rod, thereby realizing the positioning of the insertion rod. This method is simple to operate, convenient and fast. When in use, the cleaning liquid in the inner cavity can be delivered to the nozzle through the delivery pipe and then sprayed through the nozzle. The water-absorbing expansion strip can prevent the cleaning liquid from leaking out of the gap between the nozzle and the nozzle. When the nozzle needs to be replaced, it is only necessary to pull the two sets of pull rods outward to separate the pull rods from the positioning holes, and then pull the insertion rod out of the slot.

[0025] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0026] See also Figure 1-4 According to an embodiment of the utility model, a tooth washer that is easy to replace the nozzle includes a shell 1, a slot 101 is provided on the shell 1, a nozzle 4 is installed on the top of the shell 1, a nozzle 6 is installed on the outside of the nozzle 4, a fixing ring 7 is fixedly installed on the nozzle 6, and an insertion rod 702 is provided on both sides of the fixing ring 7, and a positioning hole 703 is provided on the insertion rod 702. Both sides of the shell 1 are slidably connected with a pull rod 8, and one end of the pull rod 8 is plug-in connected to the positioning hole 703. When installing the nozzle 6, the insertion rod 702 is aligned with the slot 101, and then the nozzle 6 is pressed down so that the insertion rod 702 is inserted into the inside of the slot 101, and then one end of the pull rod 8 is inserted into the positioning hole 703 on the insertion rod 702, thereby realizing the positioning of the insertion rod 702. This method is simple to operate and convenient and fast.

[0027] A transverse groove 102 is formed inside the housing 1 , and the insertion slot 101 communicates with the transverse groove 102 .

[0030] Both sides of the fixing ring 7 are fixedly connected with connecting blocks 701 , and one side of the connecting block 701 is fixedly installed with an insert rod 702 .

[0031] A slide plate 801 is fixedly mounted on the pull rod 8 , a spring 802 is connected to one side of the slide plate 801 , the spring 802 is sleeved and connected to the pull rod 8 , and a handle 803 is fixedly mounted on one end of the pull rod 8 .

[0032] The slide plate 801 and the spring 802 are both disposed inside the transverse groove 102 , and the slide plate 801 is slidably connected to the inside of the transverse groove 102 .

[0033] The bottom end of the insertion rod 702 is arranged in a wedge shape, and one end of the pull rod 8 is also arranged in a wedge shape.

[0034] The working principle of the tooth washer which is convenient for replacing the nozzle of the utility model is as follows: when installing the nozzle 6, align the insertion rod 702 with the slot 101, and then press down the nozzle 6 so that the insertion rod 702 is inserted into the inside of the slot 101. When the insertion rod 702 descends, it squeezes the pull rod 8 so that the pull rod 8 moves outward. At this time, the spring 802 is in a compressed state. When the insertion rod 702 descends to the lowest end inside the slot 101, the positioning hole 703 can align with the pull rod 8, and then the pull rod 8 is pressed by the restoring force of the spring 802.
