Obviously, the described embodiments are parts of, but not all of, the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments derived by those of ordinary skills in the art without creative effort fall within the scope of protection of the present disclosure. Accordingly, the following detailed description of the embodiments of the present disclosure shown in the drawings is not intended to limit the scope of protection of the present disclosure, but merely to represent selected embodiments of the present disclosure.

[0031] In the description of the present disclosure, the terms first, second are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implying the number of indicated technical features. Thus, a feature that is referred to by first and second may include, expressly or implicitly, one or more of the features. In the description of the present disclosure, many means two or more unless otherwise expressly and specifically defined.

[0032] As shown in FIGS. 1-17, the embodiment of the present disclosure provides a shower head with automatically resettable spray gun which includes: [0033] a shower head body 10; [0034] a flow rate switching mechanism 20; and [0035] a handle 30.

[0036] The shower head body 10 includes a water passage switching mechanism 13, a shower head 11, and spray gun head 12. The shower head 11 and the spray gun head 12 respectively communicates with the water passage switching mechanism 13.

[0037] The water passage switching mechanism 13 includes: [0038] a water passing member 130 which includes a water inlet 1300, a water passage switching cavity 1301 communicated with the water inlet 1300, a shower head water passage 1302, and a spray gun water passage 1303, the shower head water passage 1302 and the spray gun water passage 1303 respectively communicates with the water passage switching cavity 1301; and [0039] a water passage switching unit arranged in the water passage switching cavity 1301 for switching water passage between the shower head water passage 1302 and the spray gun water passage 1303.

[0040] The shower head water passage 1302 and the spray gun water passage 1303 respectively communicates with the shower head 11 and the spray gun head 12. The shower head water passage 1302 and the spray gun water passage 1303 may be arranged side by side on the same plane or may be arranged on different planes to achieve layered arrangement.

[0050] As a further improvement, in other embodiments, a circumference of a bottom portion of the switching link rod 132 is further provided with an engagement groove 1321 for receiving the first sealing rubber ring 134. The engagement groove 1321 may have various shapes and structures which are not limited herein and can be selected according practical needs.

[0051] Referring to FIG. 5, as a further improvement, in other embodiments, the water passage switching unit may further include: [0052] second sealing rubber rings 136 arranged between the fixation seat 135 and the switching cavity 1301 for preventing water leakage.

[0053] As a further improvement, in other embodiments, the switching link rod 132 further includes a hollow accommodating cavity 1320 for accommodating the elastic member 133. The elastic member 133 is accommodated in the hollow accommodating cavity 1320 for preventing deflection of the elastic member 133.

[0054] Referring to FIGS. 9-13, as a further improvement, in other embodiments, the shower head body 10 further includes: a water outlet mechanism 14 which provides water spray of granular and mist shape. The water outlet mechanism 14 communicates with the shower head water passage 1302.

[0055] A diameter of water outlet skirt (water spray range) of the water outlet mechanism 14 can be adjusted according to flow rate. The water outlet mechanism 14 specifically includes: [0056] a water outlet body 141, wherein an end surface of the water outlet body 141 is provided with a plurality of water outlet holes 1410 for providing water spray of granular and mist shape, a first rotary shaft 1412 is arranged at the center of the water outlet body 141, and an inner sidewall of the water outlet body 141 is provided with inner gear teeth 1411; [0057] a water passing member 142 sleeved on the first rotary shaft 1412, wherein the water passing member 142 is provided with first water passing hole 1421 and second water passing hole 1422; [0058] a flow rate adjustment plate 143, wherein the flow rate adjustment plate 143 is sleeved on the first rotary shaft 1412 and is attached with the water passing member 142, by rotating the flow rate adjustment plate 143, the covered area of the first water passing hole 1421 and the second water passing hole 1422 can be adjusted, such that the flow rate of the water passing member 142 can be adjusted, the flow rate adjustment plate 143 is provided with a second rotary shaft 1432; [0059] a first gear 144 sleeved on the second rotary shaft 1432, wherein the first gear 144 is engaged with the inner gear teeth 1411; and [0060] an impeller 145 sleeved on the first rotary shaft 1412, and the impeller 145 further includes a second gear 1451 arranged around the axis of the impeller 145, the second gear 1451 is engaged with the first gear 144.

[0061] When water flow drives the impeller 145 to rotate, the second gear 1451 drives the first gear 144 to rotate, since the first gear 144 and the inner gear teeth 1411 are engaged with each other, the first gear 144 can drive the flow rate adjustment plate 143 to rotate, so as to adjust the covered area of the first water passing hole 1421 and the second water passing hole 1422. Further referring to FIG. 13, when the flow rate adjustment plate 143 covers some of the water passing holes on the water passing member 142, the water passing holes on the other side that are not covered will draw the water flow to the water outlet of the water outlet body to form water spray of granular and mist shape with skirt edge. Since the area of the water passing holes of the water passing member 142 covered by the flow rate adjustment plate 143 is different, the instantaneous flow rate of the water outlet body is different. When the total area of the water passing holes of the water passing member 142 covered by the flow rate adjustment plate 143 is small, the water outlet body will have large instantaneous flow rate, and the diameter D of the water outlet skirt edge is large (e.g. D2 as shown in the drawing). When the total area of the water passing holes of the water passing member 142 covered by the flow rate adjustment plate 143 is large, the water outlet body will have small instantaneous flow rate, and the diameter D of the water outlet skirt edge is small (e.g. D1 as shown in the drawing).

[0062] The water passing member 142 is sleeved on the first rotary shaft 1412 by the first through hole 1420 arranged at the axis of the water passing member 142. In one embodiment, the areas of the first water passing hole 1421 and the second water passing hole 1422 are different. Preferably, the areas of the first water passing hole 1421 and the second water passing hole 1422 are respectively defined as S1 and S2. Preferably, 4*S2S11.5*S2. The shape of the first water passing hole 1421 and the second water passing hole 1422 may be square, circle, oval, rectangle, triangle and other regular shapes, which is not limited herein. The water passing member 142 further includes a plurality of positioning columns 1423 which are sleeved in the water outlet holes 1410 for providing water spray of granular and mist shape. In other embodiment, the number of the first water passing hole 1421 and the number of the second water passing hole 1422 are different, thus the total area of the first water passing hole 1421 and the total area of the second water passing hole 1422 are different.

[0063] The flow rate adjustment plate 143 is sleeved on the first rotary shaft 1412 through its rotary axis 1430. The flow rate adjustment plate 143 may have a regular or irregular geometrical shape. In one embodiment, the flow rate adjustment plate 143 is a semi-circular plate structure which is provided with two symmetrically arranged notches 1431. During the rotation of the notches 1431, the flow rate of the water passing member 142 is adjusted by adjusting the overlapping area with the first water passing hole 1421 and the second water passing hole 1422.

[0064] Referring to FIGS. 14-15, FIG. 14 shows a schematic diagram of the handle 30 having filtering function provided by one embodiment of the present disclosure. The handle 30 includes a casing 301 and a first filter core 302 arranged in the casing 301. The first filter core 302 is a replaceable structure. The first filter core 302 is a cylindrical structure, water flows into the filter core 302 from two sides of the cylindrical structure to get filtered and flows out from the middle.

[0065] FIG. 15 shows a schematic diagram of the handle 30 having filtering function provided by another embodiment of the present disclosure. The handle 30 includes a casing 301 and a second filter core 303 arranged in the casing 301. The second filter core 303 is a replaceable structure. The second filter core 303 has a layered structure, water flows in from one end of the layered structure and flows out from another end of the layered structure.

[0066] Referring to FIGS. 16-17, the flow rate switching mechanism 20 provided by one embodiment of the present disclosure includes: [0067] a switching ring 24; [0068] a fixation seat 23 sleeved in the switching ring 24; [0069] a sealing rubber cup 22 arranged in the fixation seat 23, wherein the sealing rubber cup 22 is provided with a first water passing port 220; [0070] a switching shaft 21 arranged at the bottom of the fixation seat 23, wherein the switching shaft 21 is provided with a second water passing port 210 corresponding to the first water passing port 220, and a toggle shaft 211, wherein one end of the toggle shaft 211 is fixedly connected to the switching shaft 21, another end of the toggle shaft 211 contacts the switching ring 24.

[0071] Rotation of the switching ring 24 can drive the toggle shaft 211 to cause the switching shaft 21 to rotate relative to the sealing rubber cup 22, so as to control the flow rate of inflow water. Specifically, when the second water passing port 210 of the switching shaft 21 completely overlaps with the first water passing port 220 of the sealing rubber cup 22, the highest flow rate can be achieved; when the second water passing port 210 of the switching shaft 21 completely misaligned with the first water passing port 220 of the sealing rubber cup 22, the lowest flow rate can be achieved.
