BATHTUB MASSAGE NOZZLE WITH SWITCH FUNCTION

Abstract

A bathtub massage nozzle with a switch function includes a nozzle body, a nozzle core seat and a nozzle surface cover. The nozzle core seat is provided with sealing rubber rings between a core seat water inlet hole and core seat air inlet holes, and at a side away from the core seat water inlet hole. The sealing rubber rings are compressed against an inner wall surface of the nozzle body, so that both ends of the nozzle body are hermetically connected, thereby forming a sealed air cavity with a better airtightness. When air flows in from the air inlet, the air entering from the air inlet passes through the air cavity and is mixed with water through the core seat air inlet holes, so that the Venturi effect is enhanced, and the air can have a greater acceleration and pressure, thereby creating more bubbles and stronger massage effect.

Description

TECHNICAL FIELD

The present invention relates to the technical field of massage nozzles, in particular to a bathtub massage nozzle with a switch function.

BACKGROUND

Bathtub massage nozzles are a common bathroom facility designed to provide a comfortable massage experience by mixing jets of water and air to generate bubbles. Traditional massage nozzle designs usually realize massage effect through the combination of nozzle body and nozzle core seat. Venturi effect is applied between nozzle body and nozzle core seat as a key mechanism to produce the bubbles. However, there are some technical limitations in the past designs, such as air leakage from the air chamber between the air inlet and the waterway due to poor airtightness of the air chamber, which may lead to unstable Venturi effect and insufficient bubble generation, thus affecting the massage effect and user experience. Therefore, in order to overcome the limitations of traditional massage nozzle designs, there is a need to provide an improved bathtub massage nozzle with a switch function to achieve better Venturi effect and air jetting effect, so that the nozzle can generate more bubbles, thus providing an improved massage effect.

SUMMARY

The present invention is directed to provide a bathtub massage nozzle with a switch function, which solves the problems of unstable Venturi effect and insufficient bubble generation caused by the poor air tightness of the air cavity between the nozzle air inlet and the waterway of some existing massage nozzles.

A bathtub massage nozzle with a switch function is provided which includes a nozzle body, a nozzle core seat and a nozzle surface cover. The nozzle body includes a water inlet end and an opposite water spraying end, and the water inlet end is provided with a water inlet and an air inlet. The water inlet and the air inlet are staggeredly arranged relative to each other, and the air inlet is closer to the water spraying end than the water inlet. The water spraying end forms an accommodating cavity extending to the water inlet end. The nozzle core seat is arranged in the accommodating cavity, and the nozzle core seat is provided with a core seat water inlet hole and a plurality of core seat air inlet holes. The nozzle core seat is provided with sealing rubber rings between the core seat water inlet hole and the core seat air inlet holes, and at a side away from the core seat water inlet hole. The sealing rubber rings are compressed against an inner wall surface of the nozzle body. A side of the nozzle core seat away from the core seat water inlet hole is provided with the nozzle surface cover.

Preferably, the inner wall surface of the nozzle body at the spraying end is provided with an annular groove that is concave toward an outer wall surface, and an outer side of the nozzle core seat near the nozzle surface cover is provided with an annular accommodating groove, and one sealing rubber ring is received in the annular accommodating groove, which is adapted to the annular groove. A nozzle core seat is inserted through the accommodating cavity contained in a nozzle body, and then the nozzle core seat is pressed, so that one sealing rubber ring arranged on the nozzle core seat is squeezed and compressed. When the sealing rubber ring is pressed to the annular groove arranged on the nozzle body, the sealing rubber ring returns to its original shape and expands into the annular groove, so that the nozzle core seat and the nozzle body can be closely connected and the side where the annular groove is located can be sealed. The other sealing rubber ring is compressed against the inner wall surface of the nozzle body between the water inlet and the air inlet, so that the side is sealed. When the two sides are sealed, a closed air cavity is formed, which further enhances the Venturi effect.

Preferably, a middle part of the nozzle body is provided with a support plane, a protrusion is provided on the support plane, and a cam adapted to the protrusion is provided on a side of the nozzle core seat opposite to the support plane. Further, the protrusion includes a perpendicular plane perpendicular to the support plane, an arc surface connected to the perpendicular plane and parallel to the support plane, and an inclined transition surface extending from the support plane to the arc surface.

When the cam reaches the lowest end of the protrusion where the protrusion is connected with the support plane, the protrusion comes into contact with the cam. The nozzle core seat is continually rotated, and the cam gradually moves upward (that is, toward the nozzle surface cover) along the inclined transition surface of the protrusion. The annular groove on the nozzle body can be easily separated from the sealing rubber ring on the nozzle core seat due to the force provided in the direction away from the water inlet end. The nozzle core seat is continually rotated, and the nozzle core seat can be easily removed from the nozzle body. With this design, it is simple and convenient to disassemble the nozzle body and the nozzle core seat. The user only needs to rotate the nozzle core seat to make the protrusion can be engaged with the cam, providing a force sufficient to make the annular groove on the nozzle body separate from the sealing rubber ring on the nozzle core seat. In this way, the user can easily replace, clean or repair the nozzle core seat, so as to achieve a better maintenance and use experience.

Preferably, the nozzle core seat is provided with a nozzle core at one end away from the core seat water inlet hole, and the nozzle surface cover is provided with a water outlet corresponding to the nozzle core.

Preferably, the nozzle core can be one of a spherical nozzle core, a straight nozzle core, a rotary nozzle core or a multi-port nozzle core. In use, different types of nozzle core seats (that is, different nozzle cores) can be chosen according to the user own preferences and needs, such as spherical, straight, rotary or multi-port nozzle cores, so as to obtain personalized and diversified massage effects.

Preferably, the nozzle core seat is provided with a catch slot, and the side of the nozzle surface cover is provided with a catch matched with the catch slot. During installation, the connection between the nozzle surface cover and the nozzle core seat is realized by engaging the catch on the nozzle surface cover into the catch slot at the nozzle core seat, which is simple and reliable.

Preferably, the outer side of the nozzle body is provided with an external thread. The bathtub massage nozzle with a switch function also includes a fastener with an internal thread, the fastener is screwed onto the external thread of the nozzle body, and is engaged with the nozzle surface cover so as to be installed at an installation position on the bathtub.
