[0050] With the improvement of people's living standards, the functional needs of shower equipment are also increasing, such as shower with spray gun, which can not only meet the daily showering needs, but also spray gun water with strong water force, thereby facilitating the cleaning of dead angle position in bathroom or bathroom. The existing spray gun shower generally has a water outlet switching device, which realizes the free switching of shower function and spray gun function by controlling the water outlet switching device. A water outlet switching device, comprising a water distribution assembly, a push rod assembly and a switching switch, the water distribution assembly has two water outlets, the switching switch is connected with the water distribution assembly and the push rod assembly respectively, the push rod assembly is driven by operating the switching switch, so that the two water outlets can be opened and closed, thereby realizing the shower water or spray gun water. However, due to the large water pressure of the water flow in the spray gun shower, the switching switch is relatively laborious when operating under the action of water pressure, so that some users such as children, the elderly, women and the like are inconvenient to use.

[0051] The present application provides a water outlet switching device.

[0052] Please refer to Figures 1-3 , Figure 1 is a part structure sectional view of an embodiment of the water outlet switching device of the present application; Figure 2 is a sectional view of the water distribution assembly of the water outlet switching device of the present application; Figure 3 is a part structure schematic diagram of an embodiment of the water outlet switching device of the present application Figure 1 .

[0053] In the embodiments of the present application, the water outlet switching device comprises:

[0054] The water distribution assembly 100 is provided with a water distribution cavity 101, a first water outlet 102 and a second water outlet 103 which communicate with the water distribution cavity 101;

[0055] The switching switch 200 is rotatably connected with the water distribution assembly 100;

[0056] The push rod assembly 300 is slidably arranged in the water distribution cavity 101 at one end, and extends to outside of the water distribution cavity 101 at the other end. The switching switch 200 is drivingly connected with the push rod assembly 300. The switching switch 200 is rotated to make the push rod assembly 300 move linearly, so as to open one of the first water outlet 102 and the second water outlet 103 and close the other one.

[0057] The pressure adjusting mechanism 400 is connected with the push rod assembly 300. The pressure adjusting mechanism 400 changes the resistance of the push rod assembly 300 in the water distribution cavity 101 by changing the water pressure in the water distribution cavity 101, so as to balance the pressure at both ends of the switching switch 200.

[0058] The water outlet switching device in one technical scheme of the embodiment comprises a water distribution assembly 100, a switching switch 200, a push rod assembly 300 and a pressure adjusting mechanism 400. The water distribution assembly 100 is provided with a water distribution cavity 101. Water flow can flow out of the water distribution cavity 101 through the first water outlet 102 or the second water outlet 103. The push rod assembly 300 is slidably arranged in the water distribution assembly 100 and can move linearly. One end of the push rod assembly 300 is arranged inside the water distribution cavity 101, so that the push rod assembly 300 can change its position in the water distribution cavity 101 by sliding. When the push rod assembly 300 is at a first position, the first water outlet 102 is closed and the second water outlet 103 is opened. When the push rod assembly 300 is at a second position, the second water outlet 103 is closed and the first water outlet 102 is opened. The pressure adjusting mechanism is connected with the push rod assembly 300, which reduces the resistance of the high-pressure water flow in the water distribution cavity 101 to the sliding of the push rod assembly 300. When one end of the switching switch 200 is pressed to make the push rod assembly 300 move from the first position to the second position, it is relatively labor-saving. When the other end of the switching switch 200 is pressed to make the push rod assembly 300 move from the second position to the first position, it is also relatively labor-saving, thereby facilitating the operation of the user.

[0059] Optionally, the pressure adjusting mechanism 400 comprises a pressure bearing part 410, which is connected with the push rod assembly 300, is slidably arranged inside the water distribution cavity 101 and divides the water distribution cavity 101 into a first sub-cavity 1011 connected with the first water outlet 102 and a second sub-cavity 1012 connected with the second water outlet 103. The pressure bearing part 410 is provided with a pressure relief hole 411, which is connected with the first sub-cavity 1011 and the second sub-cavity 1012.

[0060] Please refer to Figures 1-3 and Figure 8In the embodiment, the pressure bearing part 410 is connected with the push rod assembly 300, and the pressure bearing part 410 divides the water distribution cavity 101 into a first sub-cavity 1011 and a second sub-cavity 1012. Since the pressure bearing part 410 is movable, the sizes of the first sub-cavity 1011 and the second sub-cavity 1012 are adjustable. When the push rod assembly 300 closes the first water outlet 102, water flows out of the second water outlet 103 from the second sub-cavity 1012. When the push rod assembly 300 closes the second water outlet 103, water flows out of the first water outlet 102 from the first sub-cavity 1011. Meanwhile, the pressure bearing part 410 is provided with a pressure relief hole 411 which communicates the first sub-cavity 1011 and the second sub-cavity 1012, so that water exists in the first sub-cavity 1011 and the second sub-cavity 1012. For example, when the push rod assembly 300 closes the first water outlet 102, the first sub-cavity 1011 is not communicated with the first water outlet 102, and water only flows out of the second water outlet 103, but water exists in the first sub-cavity 1011 and the second sub-cavity 1012, so that the two sides of the pressure bearing part 410 are subjected to water pressure. The force exerted by the water in the first sub-cavity 1011 on the pressure bearing part 410 can offset part of the force exerted by the water in the second sub-cavity 1012 on the pressure bearing part 410. In this case, the resistance of water pressure that needs to be overcome by the operation of the switch 200 is much smaller. Similarly, when the push rod assembly 300 closes the second water outlet 103, the second sub-cavity 1012 is not communicated with the second water outlet 103, and water only flows out of the first water outlet 102, but water exists in the first sub-cavity 1011 and the second sub-cavity 1012, so that the two sides of the pressure bearing part 410 are subjected to water pressure. The force exerted by the water in the second sub-cavity 1012 on the pressure bearing part 410 can offset part of the force exerted by the water in the first sub-cavity 1011 on the pressure bearing part 410. In this case, the resistance of water flow that needs to be overcome by the operation of the switch 200 is also much smaller, so that the operation of the switch 200 is labor-saving. In the embodiment, the pressure regulating mechanism 400 is realized by the pressure bearing part 410 and the pressure relief hole 411, and has simple structure and is easy to realize.

[0061] Optionally, the inner wall of the water distribution cavity 101 is provided with a limiting structure which cooperates with the pressure bearing part 410 to limit the stroke of the push rod assembly 300 in the water distribution cavity 101.

[0062] Please refer to Figure 1In the embodiment, the inner wall of the water distribution cavity 101 is provided with a limiting structure for limiting the stroke of the pressure receiving part 410 sliding in the water distribution cavity 101, and further limiting the stroke of the push rod assembly 300 sliding, so that when the push rod assembly 300 moves linearly to the two ends of the stroke, one of the two water outlets can be closed and the other can be opened. The limiting structure can be a limiting protrusion provided on the inner wall of the water distribution cavity 101, which interferes with the limiting protrusion when the pressure receiving part 410 slides to limit the stroke. Alternatively, a limiting groove can be provided on the inner wall of the water distribution cavity 101, and the pressure receiving part 410 slides in the limiting groove to limit the stroke.

[0063] Optionally, the limiting structure is a limiting groove 1013, and the limiting groove 1013 is provided corresponding to the pressure receiving part 410, and the pressure receiving part 410 partially extends into the inside of the limiting groove 1013 and slides in the limiting groove 1013.

[0064] Please refer to Figures 7-10 In the embodiment, the limiting structure is a limiting groove 1013 provided on the inner wall of the water distribution cavity 101. Since in the embodiment, the water distribution cavity 101 is formed by splicing the water spraying part 110 and the water distribution part 120 in the water distribution assembly 100, the limiting groove 1013 is also formed by splicing the water spraying part 110 and the water distribution part 120. The first receiving space 111 of the water spraying part 110 has a step structure, and the water distribution part 120 has an abutting surface. When the water spraying part 110 and the water distribution part 120 are sealingly connected, the step structure and the abutting surface abut to form the limiting groove 1013. The form of the limiting groove 1013 used in the embodiment is simpler and faster in manufacturing and assembly.

[0065] Optionally, the pressure receiving part 410 has a first chamfer structure 412, and the first chamfer structure 412 is provided on the side of the pressure receiving part 410 facing the first sub-cavity 1011; and / or,

[0066] The pressure receiving part 410 has a second chamfer structure 413, and the second chamfer structure 413 is provided on the side of the pressure receiving part 410 facing the second sub-cavity 1012.

[0067] Please refer to Figure 8 and Figure 10 In the embodiment, the pressure receiving part 410 has a first chamfer structure 412. During the process of the pressure receiving part 410 sliding from the second position to the first position, the pressure receiving part 410 is always subjected to the resistance of the water flow in the first sub-cavity 1011. The provision of the first chamfer structure 412 reduces the component of the water pressure acting on the first chamfer structure 412 in the sliding direction of the pressure receiving part 410, thereby reducing the resistance of the pressure receiving part 410 and the force required to operate the switch 200.

[0068] Please refer to Figure 8 andFigure 10 In this embodiment, the pressure receiving part 410 has a second chamfer structure 413. During the sliding of the pressure receiving part 410 from the first position to the second position, the pressure receiving part 410 is always subjected to the resistance from the water flow in the second sub-cavity 1012. The second chamfer structure 413 is arranged to reduce the component of the water pressure acting on the second chamfer structure 413 along the sliding direction of the pressure receiving part 410, thereby reducing the resistance received by the pressure receiving part 410, and further reducing the force required to operate the switch 200.

[0069] Optionally, the push rod assembly 300 comprises:

[0070] a movable rod 310, a first end of the movable rod 310 being slidingly arranged inside the water distribution cavity 101, a second end of the movable rod 310 extending outside the water distribution cavity 101 through the second water outlet 103, and the pressure receiving part 410 being annularly arranged around the movable rod 310;

[0071] a resilient member 320, the resilient member 320 being elastically connected between the second end of the movable rod 310 and the water distribution assembly 100, and having a tendency to move the movable rod 310 to close the first water outlet 102 and open the second water outlet 103.

[0072] Please refer to Figure 1 and Figure 3In the embodiment, the push rod assembly 300 comprises a movable rod 310 and an elastic member 320. The movable rod 310 is movable to realize the movement of the push rod assembly 300, and then realize the opening of one of the first water outlet 102 and the second water outlet 103 and the closing of the other. In the embodiment, the movable rod 310 is arranged in the water distribution assembly 100 through the second water outlet 103. The diameter of the movable rod 310 is smaller than that of the second water outlet 103, and a gap is left between the movable rod 310 and the second water outlet 103. Two sealing rings are arranged on the movable rod 310. When the movable rod 310 moves to the first position, one of the sealing rings seals the first water outlet 102, and at this time, water flows out from the gap between the second water outlet 103 and the second water outlet 103. When the movable rod 310 moves to the second position, the other sealing ring seals the second water outlet 103, and at this time, the movable rod 310 is away from the first water outlet 102, and water can flow out from the first water outlet 102. In the embodiment, the movable rod 310 has a simple structure and is easy to manufacture. The elastic member 320 elastically connects the movable rod 310 and the water distribution assembly 100. Without external force, the elastic member 320 makes the movable rod 310 be located at the first position, that is, the first water outlet 102 is sealed and the second water outlet 103 is opened. The elastic member 320 can be made of elastic material, such as rubber or nylon, or can be a spring. In the embodiment, the elastic member 320 is a spring. Without external force, when the user opens the water valve, water automatically flows out from the second water outlet 103, that is, water flows out through the shower head. When the user presses the switching switch 200, water flows out from the first water outlet 102, that is, water flows out through the spray gun. At this time, the spring is compressed and deformed to generate elastic force. Because water has pressure, the water pressure is greater than the elastic force of the spring at this time by selecting a suitable spring. The water pressure can make the spring maintain the deformed state, and the user's hand can leave the switching switch 200. The water outlet switching device can also continuously make the spray gun outlet water, and the user does not need to continuously press the switching switch 200, which is convenient and labor-saving. After the use of the spray gun outlet water is completed, the user can press the switching switch 200 to switch to the water flow from the first water outlet 102, and then close the water valve. In this case, the spring restores to its original shape. The user can also directly close the water valve. Without the water pressure, the spring restores to its natural state from the deformed state. The spring drives the movable rod 310 to move to seal the first water outlet 102 and open the second water outlet 103. The movable rod 310 drives the switching switch 200 to rotate, so that the switching switch 200 returns to the position of making the shower head outlet water. In the case that the user forgets to switch the spray gun shower from the spray gun outlet water to the shower head outlet water, the next time of use can avoid directly from the spray gun outlet water, so as to avoid that the user or other equipment in the shower environment is impacted by high-pressure water, thereby improving the convenience and safety during use.

[0073] Please combine Figure 8 and Figure 10, in particular to the embodiment, the pressure bearing part 410 has pressure bearing surfaces S1 and S2, the end of the movable rod 310 has a pressure bearing surface S3, the force applied to the switch 200 is F1, F2, wherein F1 is the force required to drive the push rod assembly 300 to move from the first position to the second position, F2 is the force required to drive the push rod assembly 300 to move from the second position to the first position, the elastic force of the elastic member 320 is F, and the water pressure is P. Under normal circumstances, when the water valve is opened, the shower head is a shower, that is, the push rod assembly 300 is in the first position, the first water outlet 102 is closed and the second water outlet 103 is opened. As long as the sum of the force applied by the water pressure to the pressure bearing surface S1 and the elastic force F of the elastic member 320 is greater than the force applied by the water pressure to the pressure bearing surface S2, the shower can be maintained, that is, PXS1+F>PXS2; During the shower, manually switch to the spray gun, that is, the push rod assembly 300 is in the second position, the second water outlet 103 is closed and the first water outlet 102 is opened. It needs to overcome the resistance of the water pressure and deform the elastic member 320, and needs to meet PXS1+F≤PXS2+F1, that is, the force F1 applied to the switch 200 needs to meet F1≥PXS1+F-PXS2; At this time, the force applied to the switch 200 is released, and the spray gun is still maintained, which needs to meet PXS2+PXS3>PXS1+F, that is, the sum of the force applied by the water pressure to the pressure bearing surface S2 and the pressure bearing surface S3 is greater than the sum of the force applied by the water pressure to the pressure bearing surface S1 and the elastic force F of the elastic member 320. If the water valve is closed at this time, the water pressure is lost, and the push rod assembly 300 can automatically recover to the first position under the action of the elastic force F of the elastic member 320. If you want to manually switch back to the shower at this time, you need to meet PXS2+PXS3≤PXS1+F+F2, that is, the force F2 applied to the switch 200 needs to meet F2≥PXS2+PXS3-PXS1-F. The areas of the pressure bearing surfaces S1, S2 and S3 can be designed as needed to meet the functional requirements, which are not limited here. In particular to the embodiment, the area of the pressure bearing surface S1 is equal to the area of the pressure bearing surface S2, PXS2 and PXS1 are equal in size, and the forces of the water pressure on both sides of the pressure bearing part 410 cancel each other out, thereby greatly reducing the force required to operate the switch 200.

The water distribution part 120 and the water spraying part 110 can be fixed by clamping or screwing, and in the embodiment, the water distribution part 120 and the water spraying part 110 are both fixed to the shell of the shower head. In the embodiment, when the water outlet switching device is working normally, water flows into the second sub-space through the water inlet channel 122, then enters the water distribution cavity 101 through the water inlet gap 112, and then exits through the first water outlet 102 or the second water outlet 103 according to the position of the push rod assembly 300.

[0080] Optionally, the water spraying member 110 is further provided with a first water outlet channel 113, the first water outlet channel 113 being communicated with the first water outlet 102 and the external environment, the water distribution member 120 is further provided with a second water outlet channel 123, a first sliding channel 124 and a second sliding channel 125, the first sliding channel 124 being communicated with the second water outlet 103 and the second sliding channel 125, the movable rod 310 being slidably arranged in the first sliding channel 124 and the second sliding channel 125, and the movable rod 310 being sealingly connected with the second sliding channel 125, and the second water outlet channel 123 being communicated with the first sliding channel 124 and the external environment.

[0081] Please refer to Figure 2 In the embodiment, when the movable rod 310 is located at the first position, the water flow enters the first sliding channel 124 from the water distribution cavity 101 through the second water outlet 103, and then leaves through the second water outlet channel 123; when the movable rod 310 is located at the second position, the water flow enters the first water outlet channel 113 from the water distribution cavity 101 through the first water outlet 102, and then leaves. The movable rod 310 is arranged in the first sliding channel 124 and the second sliding channel 125, the second water outlet channel 123 is communicated with the first sliding channel 124 and the external environment, the first sliding channel 124 is communicated with the water distribution cavity 101 through the second water outlet 103, the channel required for sliding the movable rod 310 and the channel required for the water outlet of the shower are combined into one, so that the water outlet switching device of the embodiment has a more compact structure, and the size of the shower gun is smaller.

[0082] Optionally, the push rod assembly 300 further comprises:

[0083] The first sealing member 330 and the second sealing member 340 are both sleeved on the movable rod 310, the first sealing member 330 is arranged on the side of the pressure bearing portion 410 facing the first water outlet 102 to seal the first water outlet 102, and the second sealing member 340 is arranged on the side of the pressure bearing portion 410 facing the second water outlet 103 to seal the second water outlet 103.

[0084] Please refer to Figure 3 and Figure 8In the embodiment, the push rod assembly 300 comprises a first sealing member 330 and a second sealing member 340. The first sealing member 330 is used to seal the first water outlet 102 and can be an O-shaped sealing ring or a Y-shaped sealing ring. The second sealing member 340 is used to seal the second water outlet 103 and can be an O-shaped sealing ring or a Y-shaped sealing ring. In the embodiment, the first sealing member 330 and the second sealing member 340 are both Y-shaped sealing rings. The outer periphery of the movable rod 310 is provided with mounting grooves corresponding to the Y-shaped sealing rings. The two Y-shaped sealing rings are correspondingly arranged in the mounting grooves. The Y-shaped sealing rings have lips. The lips of the two Y-shaped sealing rings extend out of the mounting grooves and are oppositely arranged towards the pressure-bearing part 410. The corresponding lips are provided with chamfers at the first water outlet 102 and the second water outlet 103. When sealed, the water pressure tightly presses the lips against the chamfers, which can improve the sealing effect and reduce the possibility of water leakage.

[0085] Optionally, the outer periphery of the movable rod 310 is further provided with an avoiding notch 311. The avoiding notch 311 is arranged on the side of the second sealing member 340 away from the pressure-bearing part 410. When the push rod assembly 300 closes the first water outlet 102, the avoiding notch 311 extends from the second sub-cavity 1012 into the first sliding channel 124.

[0086] Please refer to Figure 2 , Figure 3 and Figure 8 In the embodiment, the outer periphery of the movable rod 310 is provided with the avoiding notch 311. The avoiding notch 311 increases the gap between the movable rod 310 and the second water outlet 103. When the push rod assembly 300 is in the first position, the avoiding notch 311 can ensure that the water flow entering the first sliding channel 124 has a water pressure and a water volume that meet the needs, that is, the water flow leaving the second water outlet 123 has a water pressure and a water volume that meet the needs, so as to ensure that the shower water outlet meets the use requirements. The specific shape of the avoiding notch 311 can be adjusted and designed according to needs to meet the functional requirements, which is not limited herein.

[0087] Optionally, the push rod assembly 300 further comprises a third sealing member 350. The third sealing member 350 is sleeved on the outer periphery of the movable rod 310 and elastically abuts and slidably connects with the inner wall of the second sliding channel 125. The third sealing member 350 is provided with a deformation groove 351. The deformation groove 351 is annularly arranged on the third sealing member 350, and the opening of the deformation groove 351 faces the pressure-bearing part 410.

[0088] Please refer to Figure 3 and Figure 8In the embodiment, the push rod assembly 300 comprises a third sealing member 350 for sealing the gap between the movable rod 310 and the second sliding channel 125. The third sealing member 350 can be an O-shaped sealing ring or a V-shaped sealing ring, etc. In the embodiment, the third sealing member 350 is a V-shaped sealing ring. The outer periphery of the movable rod 310 is provided with a mounting groove corresponding to the V-shaped sealing ring. The V-shaped sealing ring is partially arranged in the mounting groove. The V-shaped structure of the V-shaped sealing ring forms a deformation groove 351. The opening of the deformation groove 351 faces the pressure bearing part 410. Therefore, when the second water outlet 103 is opened, the water flows into the deformation groove 351, so that the two side walls of the deformation groove 351 are deformed by being stretched apart. One side wall is deformed towards the movable rod 310, and the other side wall is deformed towards the inner wall of the second sliding channel 125. Thus, the movable rod 310 and the second sliding channel 125 are well sealed, and the possibility of water leakage from the second sliding channel 125 is reduced.

[0089] Please refer to Figure 1 , Figure 3 and Figure 11 In the embodiment, the sliding of the push rod assembly 300 is driven by the switch 200 through the connecting pin 500. The second end of the movable rod 310 is provided with a through hole corresponding to the connecting pin 500. The first end of the connecting pin 500 is movably arranged in the through hole. The diameter of the end of the connecting pin 500 is larger than the inner diameter of the through hole, so as to prevent the first end of the connecting pin 500 from completely penetrating through the through hole. The structure is simple and convenient to manufacture. The movable rod 310 is slidably arranged in the water distribution member 120 and can move linearly along a first direction. The connecting pin 500 can move linearly along a second direction in the through hole. The first direction is perpendicular to the second direction. The switch 200 is provided with a driving hole 221. The second end of the connecting pin 500 extends into the driving hole 221 and can move in the driving hole 221. The rotational movement of the switch 200 can be decomposed into movements along the first direction and the second direction. The movement of the switch 200 along the first direction drives the connecting pin 500 to change the position in the first direction through the driving hole 221, and further drives the push rod assembly 300 to change the position in the first direction, so as to realize the sliding of the push rod assembly 300 in the water distribution cavity 101. Since the connecting pin 500 is movable in the second direction, the movement of the switch 200 along the second direction is compensated by the relative displacement between the connecting pin 500 and the inner wall of the driving hole 221 in the second direction, so as to finally realize the sliding of the push rod assembly 300 driven by the rotation of the switch 200. The switch 200 drives the connecting pin 500 through the driving hole 221, and the connecting pin 500 penetrates through the push rod assembly 300 to drive the push rod assembly 300. The fault tolerance of the whole connecting structure is higher. The disconnection between the parts caused by slight deformation or position deviation is less likely to occur, so as to avoid the control failure of the switch 200.

[0090] Please refer to Figure 12In the embodiment, the driving hole 221 comprises first, second and third sections which are adjacent and have different inner diameters, the first and third sections are arranged on opposite sides of the second section, and the inner diameters of the first and third sections are both larger than that of the second section. The position of the connecting pin 500 can be changed by driving the toggle switch 200, but the connecting pin 500 will not rotate with the toggle switch 200. Since the second end of the connecting pin 500 is movably inserted into the driving hole 221 of the toggle switch 200, and the toggle switch 200 can rotate, the contact position between the connecting pin 500 and the inner wall of the driving hole 221 can be changed. In the embodiment, the contact position between the connecting pin 500 and the inner wall of the driving hole 221 is located at the middle part of the connecting pin 500, so the driving hole 221 needs to have a shape similar to a middle thin and two ends thick shape, thereby preventing the toggle switch 200 from being stuck with the connecting pin 500 when the toggle switch 200 rotates.

[0091] Please refer to Figure 11 and Figure 12 In the embodiment, the toggle switch 200 comprises an operation part 210, a driving part 220 and a button 230. The button 230 is arranged on the side of the operation part 210 away from the driving part 220, and the button 230 and the operation part 210 can be fixed by clamping or screwing. The operation part 210 is provided with an axle hole, and the operation part 210 and the water distribution piece 120 are connected by the cooperation of the axle hole and a rotating shaft. The driving part 220 is connected with the operation part 210, and can be fixed by clamping or can be integrally formed. In the embodiment, the axle hole is arranged at the middle part of the operation part 210, one end of the driving part 220 is connected with the operation part 210 at the position close to the axle hole, and the driving hole 221 is arranged at the other end of the driving part 220. The user presses the button 230 to make the operation part 210 rotate around the rotating shaft, and then make the driving part 220 connected with the operation part 210 rotate, thereby realizing the rotation of the driving hole 221 at the other end of the driving part 220. The driving part 220 is further provided with a avoiding space 222, the driving hole 221 is communicated with the avoiding space 222, and the movable rod 310 is slidably arranged in the avoiding space 222. The avoiding space 222 makes the structure of the toggle switch 200 and the push rod assembly 300 more compact, reduces the occupied space, and makes the product more miniaturized and lightened.

[0092] The application further provides a shower gun, which comprises a water outlet switching device. The specific structure of the water outlet switching device is referred to the above-mentioned embodiments. Since the shower gun adopts all the technical solutions of the above-mentioned embodiments, it has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. The shower gun has a shell with a receiving cavity. The water outlet switching device is arranged inside the receiving cavity except the button 230. The shell is provided with a water inlet connector for connecting the water inlet channel 122 of the water distribution member 120 and the external water channel. The water flow enters the water inlet channel 122 of the water distribution member 120 from the external water channel through the water inlet connector, then enters the second sub-space through the water inlet channel 122, and then enters the water distribution cavity 101 from the second sub-space through the water inlet gap 112 of the water distribution member 110. The water flow exits through the first water outlet 102 or the second water outlet 103 according to the position of the push rod assembly 300. The setting of the pressure bearing part 410 and the pressure relief hole 411 makes the shower gun of the embodiment less forceful when switching between the shower gun water outlet and the shower head water outlet, so that the shower gun can be easily used by people with less strength such as the elderly, children and women.

[0093] The above-mentioned is only the optional embodiment of the application, and does not limit the patent scope of the application. Any equivalent structural transformation, direct / indirect application in other related technical fields based on the inventive concept of the application and the content of the specification and drawings are included in the patent protection scope of the application.
