Description

TECHNICAL FIELD

[0001] The utility model belongs to oral cavity nursing technical field, concretely relates to a oral cavity flusher. BACKGROUND

[0002] In today's society where personal hygiene and health are increasingly valued, oral cleaning and care have become an indispensable part of people's daily life. Traditional oral cleaning methods, such as brushing teeth and using dental floss, can effectively remove food residues and plaque on the surface of teeth and in the interdental space to some extent, but the cleaning effect on the deep part of the oral cavity is relatively limited. With the progress of science and technology and the improvement of people's health awareness, oral flushers, as a new type of oral cleaning tool, have emerged as the times require and gradually gained popularity among consumers.

[0003] The oral flusher can effectively remove food residues, soft dirt and plaque on the gum line and oral mucosa by high-pressure water flow, stimulate the gums and promote blood circulation to prevent periodontal disease.

[0004] However, the existing oral flusher has the disadvantage of fixed flushing direction, and most flushers can only provide fixed flushing direction, which cannot meet the needs of users for precise flushing of different oral cavity areas. For example, it is difficult to achieve ideal cleaning effect for the wisdom tooth area in the deep part of the oral cavity or the interdental space that is difficult to reach. SUMMARY

[0005] To solve the above problems, the utility model provides an oral flusher, which can provide fixed flushing direction and meet the needs of users for precise flushing of different oral cavity areas.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: an oral flusher, comprising a shell body, an active groove one is formed in the inside of the shell body, a hollow ball is movably arranged in the active groove one, the hollow ball is connected with a spray pipe, a meshing groove is formed in the curved side surface of the hollow ball, the meshing groove is connected with a positioning protrusion, the positioning protrusion is arranged on the inner wall of the active groove one, a recess is formed in the inner wall of the active groove one opposite to the positioning protrusion, the recess is connected with a ball, one end of the ball is connected with a spring arranged in the recess, the other end of the ball is attached to and extrudes the curved side surface of the hollow ball, the active groove one is connected with a placing groove in a penetrating mode, a hose is arranged in the placing groove, the hose is connected with the hollow ball and a micro water pump, the micro water pump is arranged in an outer thread cylinder, the outer thread cylinder is threadedly connected with the top end of a connecting cylinder, and a control panel is arranged on the outside of the shell body.

[0007] The utility model has the advantages of:

[0008] The flexible adjustment of the washing direction is realized by the movable groove one, the hollow ball, the positioning protrusion and the adjusting rocker, etc.

[0009] The ball and the spring can elastically support the hollow ball, so that the engagement groove formed on the hollow ball is clamped with the positioning protrusion, the hollow ball is prevented from moving at will, and the stability of the washing direction is ensured.

[0010] In order to drive the spray pipe to adjust the washing direction within a certain range:

[0011] As a further improvement of the above technical solution: the movable groove one is composed of two adjacent spherical grooves and a cylindrical groove connecting the two spherical grooves, and the inner diameters of the spherical grooves and the cylindrical groove are the same.

[0012] The beneficial effect of the improvement is that the setting of the movable groove one enables the hollow ball to be separated from the positioning protrusion, thereby driving the spray pipe to adjust the washing direction within a certain range.

[0013] In order to adjust the position of the hollow ball:

[0014] As a further improvement of the above technical solution: the top end of the movable groove one is provided with an active window one penetrating the outer shell, one side inner wall of the movable groove one is provided with an active window two penetrating the outer shell, a plurality of positioning protrusions are arranged at equal intervals around the axis of the movable groove one, the spray pipe extends out of the active window one, the hollow ball is connected with the adjusting rocker, and the adjusting rocker extends out of the active window two.

[0015] The beneficial effect of the improvement is that the position of the hollow ball can be adjusted by pressing and rotating the adjusting rocker, thereby changing the washing direction of the spray pipe.

[0016] In order to effectively elastically support the hollow ball:

[0017] As a further improvement of the above technical solution: the open inner diameter of the groove towards the movable groove one is not greater than the diameter of the ball.

[0018] The beneficial effect of the improvement is that the ball can be stably clamped in the groove, and at the same time, the hollow ball can be effectively elastically supported.

[0019] In order to effectively extract water source:

[0020] As a further improvement of the above technical solution: the water outlet of the micro water pump is connected with a hose, the water inlet of the micro water pump is connected with a water suction pipe, and the water suction pipe is movably connected with the bottom surface of the outer threaded cylinder.

[0021] The beneficial effect of the improvement is that the micro water pump can draw water source through the water suction pipe, and deliver water flow to the hollow ball through the hose, and finally spray out through the spray pipe.

[0022] In order to avoid the hose being squeezed and blocked when the hollow ball rotates:

[0023] As a further improvement of the above technical solution: the placing groove is a spherical groove structure.

[0024] The beneficial effect of the improvement is that when the hollow ball rotates to adjust the angle of the spray pipe, the hose is bent along with the rotation of the hollow ball, and the placing groove provides effective space for the bending of the hose.

[0025] In order to effectively draw water:

[0026] As a further improvement of the above technical solution: the top side of the connecting cylinder is provided with a one-way valve.

[0027] The beneficial effect of the improvement is that when flushing, external air can enter the connecting cylinder through the one-way valve, avoiding the formation of negative pressure in the connecting cylinder.

[0028] The parts not involved in the device are the same as or can be realized by the prior art. BRIEF DESCRIPTION OF DRAWINGS
