Massage bathtub and massage nozzle

Abstract

The invention discloses a massage nozzle. The massage nozzle comprises a nozzle body, a nozzle mandrel and a nozzle decorative cover, wherein the nozzle mandrel is connected to a first cavity in the nozzle body; a second cavity is formed between a water outlet nozzle in the nozzle mandrel and the nozzle mandrel; an air inlet is formed in the periphery of the nozzle body; an air pump is communicated with the first cavity through the air inlet; an air inlet hole is formed in the side wall of the nozzle mandrel; the first cavity is communicated with the second cavity through the air inlet hole; the nozzle decorative cover is provided with an air outlet hole communicated with the second cavity and a water outlet hole communicated with the water outlet nozzle; and the air outlet direction of the air outlet hole is intersected with the water outlet direction of the water outlet hole. As the nozzle is added with the air pump with power, a negative-pressure natural air absorption mode in the prior art is changed to positive-pressure air intake to largely enhance the massage force of a water column, and the water column contains rich bubbles through airflow to enable the massage effect to become richer. The invention further discloses a massage bathtub including the massage nozzle.

Description

technical field [0001] The invention relates to the technical field of bathing equipment, in particular to a massage bathtub and a massage spray head thereof. Background technique [0002] In existing hydromassage bathtubs or surf bathtubs, its massage nozzle generally adopts the mode of negative pressure natural suction for massage. The working principle of the negative pressure natural suction massage method is: install a special bathtub water pump on the massage bathtub, and the bathtub water pump is connected to the nozzle through a pipe. When the water pump sprays water from the nozzle through the pipe, due to the high-speed movement of the water flow, the setting A vacuum area is generated at the air channel on the nozzle; because the external air pressure is greater than the air pressure in the vacuum area, under the action of the external air pressure, the air is brought into the air channel of the nozzle to mix with water, and then spray out at the same time.

AI Technical Summary

Problems solved by technology

However, because the air is brought into the water by the negative pressure vacuum area generated by the high-speed water flow, it is a passive method, so the massage force is small and the efficiency is very low. The consistency of the product is very poor, and often the same specification and model None of the products achieve consistent results

This massage method has a single effect, and because it is sprayed in water, the spray resistance is very large, and the distance of the massage water column sprayed by the nozzle is relatively short. For example, when it is greater than 100mm, the human body can hardly feel the massage feeling.

It can be seen that the existing massage bathtub has the disadvantages of small massage force and single massage effect

[0003] Therefore, how to solve the problem that the massage force of the existing jacuzzi is small and the massage effect is single is a technical problem that those skilled in the art need to solve at present.
