Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0019] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0021] Referring to the attached drawings of the specification, a water path structure for preventing accidental injection includes a water outlet 10 that can discharge gun water. The gun water mentioned here refers to water with fast flow and high water pressure, and can also be called high-speed high-pressure water. The water outlet is provided with a water inlet 11 and a water outlet 12. The water inlet cooperates with a switching mechanism 21 in the main body 20, and the water path is led to the water inlet through the switching mechanism. A water outlet 13 located between the water inlet and the water outlet is also provided in the water outlet body, and the water outlet connects the water inlet and the water outlet. A movable shaft 30 is also provided in the water outlet body, and one end of the movable shaft can block the water outlet so that the water in the water inlet cannot flow to the water outlet through the water outlet. At this time, you can refer to the attached drawings of the specification. Figure 2 The water outlet is also provided with a channel 14, in which a rolling steel ball 40 is provided. The rolling of the steel ball can move the movable shaft to block or open the water outlet. The steel ball can roll arbitrarily in the channel under its own gravity. When the steel ball moves to the axial position of the movable shaft, the steel ball can drive the movable shaft to move toward the water outlet. At this time, the movable shaft is supported by the steel ball, so that the movable shaft cannot move toward the channel direction, and the movable shaft blocks the water outlet.

[0022] Preferably, a spring 31 is provided between the moving shaft and the water outlet, see the accompanying drawings of the specification. Figure 3In one embodiment: the spring can make the movable shaft move toward the water outlet, ensuring that the movable shaft is in a blocked state when not affected by the steel ball. At this time, the water pressure can push the movable shaft to move toward the channel. Specifically, when the steel ball does not act on the movable shaft and the water pressure is greater than the spring force, the water pressure can drive the movable shaft to move toward the channel to keep the water outlet open. When there is no water pressure, the spring force drives the movable shaft to move toward the water outlet to seal the water outlet. In another embodiment, the spring can make the movable shaft move toward the channel. When not affected by the steel ball, the water outlet is open. When the steel ball acts on the movable shaft, the steel ball drives the movable shaft to move toward the water outlet, and the water outlet remains blocked. At the same time, the force of the steel ball on the movable shaft is greater than the force of the spring on the movable shaft or the sum of the force and the water pressure. In this way, the steel ball can drive the movable shaft to move toward the water outlet. The above two embodiments can restore the movable shaft to block the water outlet in the overall water-off state or when the steel ball rolls.

[0023] Furthermore, an annular flange 32 is provided at one end of the movable shaft, and a sealing ring 33 that can cooperate with the water outlet seal is provided on the outer periphery of the annular flange. The other end of the movable shaft can extend into the channel, and a guide slope 34 is provided at the other end of the movable shaft. The steel ball can cooperate with the guide slope to drive the movable shaft to move toward the water outlet to achieve the blocking of the water outlet. When the steel ball moves toward the movable shaft, it first cooperates with the guide slope to move the movable shaft toward the water outlet, and then the steel ball supports the other end of the movable shaft to prevent the high-speed and high-pressure water from moving the movable shaft toward the channel.

[0024] Furthermore, when there is no water pressure, the spring will drive the moving shaft to seal the water outlet. When there is water pressure and the steel ball falls on the axial direction of the moving shaft, the moving shaft cannot move forward into the channel, thereby sealing the water outlet. When the steel ball is not on the axial direction of the moving shaft, the water pressure is greater than the spring force, thereby driving the moving shaft forward into the channel and opening the water outlet.

[0025] Specifically, the utility model comprises a shower body 20, on which a water outlet 50 is arranged, and the water inlet end of the water outlet is connected to the water outlet; Figure 2 When the water outlet of the water outlet is facing upward, the steel ball cooperates with the movable shaft so that one end of the movable shaft blocks the water outlet; refer to the attached figure of the specification Figure 3 When the water outlet direction of the water outlet is downward, the steel ball moves and separates from the movable shaft. Under the action of water pressure (or under the action of a spring at the same time), one end of the movable shaft is separated from the water outlet, and the water outlet connects the water inlet and the water outlet.

[0026] Preferably, a drainage channel 35 which can be connected to the water inlet is provided in the middle of the movable shaft, and a drainage hole 36 is also provided on the movable shaft, and the drainage hole can connect the drainage channel and the water outlet.

[0027] The utility model is more specifically: State 1, refer to the accompanying drawings of the specification Figure 2 :The water outlet direction of the water outlet is upward. 1. At this time, under the action of gravity, the steel ball is at point A of the channel, blocking the moving axis from moving to the right. 2. After the water is turned on, the water can only flow out through the pressure relief hole, and the flow rate is very small, preventing the upward spray; State 2, refer to the attached figure of the instruction manual Figure 3 :The water outlet direction of the water outlet is downward. 1. At this time, under the action of gravity, the steel ball is at point B of the channel and does not block the moving shaft from moving to the right. 2. After the water is passed, under the action of water pressure, the spring is pushed to the right and compressed, and the moving shaft moves to the right (in the direction of the channel), opening the waterway to achieve normal flow water supply.

As mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
