Description

Telescopic nozzle

Technical Field

The utility model relates to the technical field of oral care, in particular to a telescopic nozzle.

Background

The food debris lodged in the crevices of the teeth, in addition to being uncomfortable and carrying bacteria itself, is more harmful in that it provides nutrients to the plaque. If not removed in time, plaque can easily become calcified, become "tartar" and accumulate in the root of the tooth, compress and stimulate the periodontal environment, and atrophy the periodontal. The tooth flusher can solve the problem well. The tooth flushing device is an auxiliary tool for cleaning the oral cavity, utilizes a pulse water flow impact mode to clean teeth and tooth gaps, is mainly portable and table-type, and generally has flushing pressure of 0 to 90 psi.

The nozzle is an important part of the tooth flushing device, but the existing nozzle is long when being installed on the tooth flushing device and is inconvenient to carry, and if the existing nozzle is detached, the existing nozzle needs to be additionally carried, so that the existing nozzle is very inconvenient and needs to be improved urgently.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects and shortcomings of the prior art and provide a telescopic nozzle which has the advantages that a spray rod can be telescopic relative to a piston cylinder and can retract into the piston cylinder.

In order to achieve the purpose, the utility model adopts the technical scheme that: a telescopic nozzle, includes spray lance and shower nozzle, still includes: the piston is assembled on the spray rod, and the piston cylinder is sleeved on the spray rod and the outer side of the piston and is used for the spray rod and the piston to slide up and down.

The utility model further provides that the piston is detachably assembled at the outer side of the lower end of the spray rod.

The utility model is further provided with a sealing silica gel ring sleeved outside the piston.

The utility model is further provided with a stop ring with the inner diameter smaller than the outer diameter of the piston, which is arranged in the upper end of the piston cylinder.

The utility model further provides that a camera is assembled on the spray rod.

The utility model is further provided with a wire outlet hole for leading out a circuit of the camera on the piston cylinder.

The utility model further provides that the spray rod and the spray head are integrally formed.

After the technical scheme is adopted, the utility model has the beneficial effects that:

1. according to the utility model, the spray rod is provided with the piston, and the outer side of the spray rod is sleeved with the piston cylinder, so that the spray rod can extend and retract relative to the piston cylinder; due to the interaction between the piston and the piston cylinder, the spray bar can also be positioned after being pulled upwards.

2. In the utility model, the sealing silica gel ring is sleeved outside the piston, so that the waterproof effect of the nozzle is enhanced.

3. In the utility model, the stop ring is arranged inside the upper end of the piston cylinder, so that the whole spray rod cannot be pulled out of the piston cylinder.

4. In the present invention, the spray bar and the spray head are integrally formed. There are two cases, one in which the spray head is fixed to the head of the spray bar; another situation is where the spray head is considered to be part of the spray bar, i.e., the spray head is the head of the spray bar.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment as necessary without making a contribution thereto after reading the present specification, but all are protected by patent laws within the scope of the claims of the present invention.

The embodiment relates to a telescopic nozzle for a tooth flushing device, which comprises a spray rod 1 and a spray head 2, and further comprises the following components: the piston 3 is assembled on the spray rod 1, and the piston cylinder 4 is sleeved outside the spray rod 1 and the piston 3 and is used for the spray rod 1 and the piston 3 to slide up and down. Because the piston 3 can move up and down in the piston cylinder 4, the spray rod 1 can be driven to extend and retract relative to the piston cylinder 4, and the spray rod 1 can retract into the piston 3. Furthermore, due to the interaction between the piston 3 and the piston cylinder 4, the spray bar 1 can be positioned after being pulled upwards and cannot slide downwards. Such design for when this telescopic nozzle application is on dashing the tooth ware, the nozzle can retract towards tooth ware inside, makes the volume of whole product become very little, and the nozzle also need not to accomodate alone moreover, and is very convenient when carrying.

As shown in fig. 3 and 4, the piston 3 is detachably mounted outside the lower end of the spray bar 1. In the present embodiment, the piston 3 and the lower end of the spray bar 1 are assembled by screw threads, specifically, the piston 3 is screwed from the lower end of the spray bar 1, and in other embodiments, there may be other assembling manners, such as screw threads, between the piston 3 and the spray bar 1.

In order to enhance the waterproof effect of the telescopic nozzle, as shown in fig. 3 and 4, a silicone sealing ring 5 is sleeved outside the piston 3.

As a preferable scheme, as shown in fig. 1 to 4, a stop ring 6 with an inner diameter smaller than the outer diameter of the piston 3 is provided inside the upper end of the cylinder of the piston 3. By providing the stop ring 6, the spray bar 1 is not pulled out of the piston 3 cylinder in its entirety when it is extended.

In the present embodiment, the spray bar 1 is equipped with a camera 7, i.e. the telescopic nozzle has a visual function.

As shown in fig. 1-4, the piston cylinder 4 is provided with an outlet hole 8 for leading out a line 9 of the camera 7. The wire outlet hole 8 can be used for leading out a line 9 of the camera 7, so that the line 9 can be conveniently connected to the main circuit board when the electric toothbrush is applied to the tooth flushing device.

The spray bar 1 and the spray head 2 are integrally formed. There are two cases, one of which is that the spray head 2 is fixed at the head of the spray bar 1; alternatively, it may be considered that spray head 2 is part of spray bar 1, i.e. spray head 2 is the head of spray bar 1.

The working principle of the utility model is roughly as follows: the spray rod 1 is provided with the piston 3, and the outer side of the spray rod 1 is sleeved with the piston cylinder 4, so that the spray rod 1 can extend and retract relative to the piston cylinder 4 and can retract into the piston cylinder 4; due to the interaction between the piston 3 and the piston cylinder 4, the spray bar 1 can also be positioned after being pulled upwards.

The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention should be covered by the claims of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
