The working principle is as follows:

the pressing piece 300 has a pressing stroke and a restoring stroke, in which the pressing piece 300 slides along and rotates around the first axis with respect to the body 100.

In the initial state, the first helical tooth 30121 is partially opposite to the second helical tooth 232, and the third helical tooth 3022 is located in the gap between the adjacent fourth helical teeth 214;

when different water outlet modes need to be switched, the button 3011 is pressed, the pressing piece 300 enters a pressing stroke, the button 3011 pushes the pressing cover 3012 and the rotating piece 302 to slide upwards relative to the body 100 along the first axis, the first helical teeth 30121 and the second helical teeth 232 are in inclined surface fit, so that the pressing cover 3012 also rotates about 45 degrees around the first axis, and the rotating piece 302 also rotates about 45 degrees around the first axis due to the fact that the pressing cover 3012 and the rotating piece 302 are in rotation stop fit, so that the third helical teeth 3022 are separated from gaps between adjacent fourth helical teeth 214 and partially opposite to the fourth helical teeth 214 after rotating about 45 degrees;

when the button 3011 is released, the pressing element 300 enters a reset stroke, the first elastic element 400 applies a downward force to the rotating element 302, the rotating element 302 is driven to rotate 45 ° further in the same direction and move downward, the third helical tooth 3022 rotates about 45 ° and falls into a gap adjacent to the initial position, and the first helical tooth 30121 is opposite to the portion of the second helical tooth 232 adjacent to the initial position.

That is, each time the button 3011 is pressed and released, the block portion 3021 rotates by about 90 °. Therefore, when different water outlet modes need to be switched, the button 3011 is pressed and released once, and the communication state between the first water dividing port 211 and the second water dividing port 212 and the water inlet can be changed.

In the first water discharge state, as shown in fig. 12, the blocking portion 3021 blocks the second water dividing port 212 such that only the first water dividing port 211 is communicated with the water inlet, and at this time, the water flow of the water inlet enters the water dividing chamber 01 through the second water passage hole 222, flows out through the first water dividing port 211, enters the first water passage port 215, sequentially enters the first water inflow port 324 through the first water passage port 3111 and the third water passage port 315, and then enters the first water discharge chamber to flow out from the first water outlet, so as to be pressurized water.

In the second water discharge state, as shown in fig. 13, the blocking portion 3021 blocks the first water dividing port 211 so that only the second water dividing port 212 is communicated with the water inlet, at this time, the water flow of the water inlet enters the water dividing chamber 01 through the second water passage 222, flows out through the second water dividing port 212 to enter the second water passing port 216, sequentially passes through the second water passing port 3112, the fourth water passing port 3121, the water inlet passage 202, and the water passing passage 203, flows into the second water passing port 325 and the third water passing port 326, and then flows out from the second water outlet through the second water outlet chamber and the third water outlet chamber, and is air-based shower water.

In a third water discharge state (not shown in the figure), the blocking portion 3021 partially blocks the first water dividing port 211 and the second water dividing port 212 and enables the first water dividing port 211 and the second water dividing port 212 to be simultaneously communicated with the water inlet, and at this time, the first water outlet and the second water outlet both discharge water, which is pressurized water and air-based shower water.

Therefore, the top shower head can discharge pressurized water, air type rainwater and mixed water of the pressurized water and the air type rainwater, so that the requirements of users in various aspects are met, and the user experience is good; because of different regions, the water pressure is different across the country, the water pressure in some places is low, the water pressure in some places is higher, when a user purchases the top-spraying shower, the user does not know whether to select the supercharging type top-spraying shower or the common type top-spraying shower because of no certain concept of the water pressure, and the water pressure in the user home is normal, the user purchases the supercharging type, when the water pressure is high, the user can feel stabbing pain and poor in experience effect because the water outlet hole of the supercharging type is small, and when the water pressure of the user is low, the user purchases the common type, so that the water outlet flow is small, the water spray is thin and pulled, and the user experience is poor; in the technical scheme, the first water outlet can form pressurized water flow, so that a user can buy the top-spraying shower head with good experience effect without knowing excessive water pressure when buying, and only needs to switch the first water outlet or the second water outlet to discharge water when using, thereby further meeting the requirements of users in various regions and being convenient and fast to use by the user; the pressing member 300 is installed on the body 100, and is not easily confused by a user when operating the pressing member.

Preferably, each first water outlet group and each second water outlet group are arranged at intervals around the first axis, so that when the top shower head only discharges water from the first water outlet, only discharges water from the second water outlet or simultaneously discharges water from the first water outlet and the second water outlet, the whole water outlet surface can discharge water comprehensively and uniformly instead of only discharging water from the inner ring or only discharging water from the outer ring, the water outlet area is wider, and the user experience is better. The third water outlet group is arranged in the area of the first water outlet group, so that the second water outlet is further comprehensively arranged on the water outlet surface, the user experience is good, when the first water outlet and the second water outlet simultaneously discharge water, the water flow of the first water outlet and the water flow of the second water outlet are better matched, and the user experience is better.
