Description

Technical Field

[0001] The present application relates to the technical field of bathroom, and in particular to a drawer head. Background Art

[0002] Existing faucets have various structures, but the water spouts of faucets of this type are generally fixedly installed on the faucets, and the water spouts cannot be pulled out or rotated to change the direction of water discharge. Therefore, when the faucets used in wash basins, vegetable sinks, etc. need to be pulled out or the direction of water discharge needs to be changed, it is very inconvenient to use traditional faucets, which can only discharge water in fixed places or in fixed directions. In order to solve the above problems, pull-out heads for faucets have been developed on the market.

[0003] In the related technology, the water inlet of the pull-out head can form a pull-out water outlet structure through the cooperation between the pull-out tube and the faucet body. A water outlet panel will be provided at the water outlet of the pull-out head. When the faucet supplies water, the tap water will be directly supplied to the pull-out head through the pull-out tube, and finally discharged through the water outlet panel, so as to freely adjust the water outlet position or direction.

[0004] With regard to the above-mentioned related technologies, the inventors believe that the water outlet function on the pull-out head is realized by the water outlet holes on the water outlet panel, and the water outlet form is relatively single. In actual use, users often need different forms of water outlets such as foam water, shower water, flushing water, etc. to meet different usage needs, so improvement is needed. Summary of the invention

[0081] When it is necessary to use the sealing ring 10 to isolate the middle chamber 152 and the lower chamber 151 of the primary connecting chamber 15, it is only necessary to directly press the first plug 7. The first plug 7 can drive the sealing ring 10 to move downward to achieve the effect of isolating the middle chamber 152 and the lower chamber 151. When the sealing ring 10 isolates the middle chamber 152 and the lower chamber 151 of the primary connecting chamber 15, because the water pressure in the middle chamber 152 and the upper chamber 153 is relatively large, even if the user releases the first plug 7, the isolation effect between the middle chamber 152 and the lower chamber 151 can be ensured at all times.

[0082] When it is necessary to use the sealing ring 10 to isolate the middle chamber 152 and the lower chamber 151 of the primary connecting chamber 15, it is only necessary to press the button 32. The button 32 will be able to drive the sealing ring 10 to rise through the active clamping relationship between the connecting rod 31 and the first plug 7. When the sealing ring 10 rises to the top, it can achieve the effect of isolating the middle chamber 152 and the upper chamber 153. When the sealing ring 10 isolates the middle chamber 152 and the upper chamber 153 of the primary connecting chamber 15, because the water pressure in the middle chamber 152 and the lower chamber 151 is relatively large, even if the user releases the first plug 7, the isolation effect between the middle chamber 152 and the upper chamber 153 can be ensured at all times.

[0083] Among them, it should be noted that when the water pressure inside the pull-out head is high due to the water supply from the faucet, when the state of switching from the first-level water outlet channel 11 to the second-level water outlet channel 12 is switched, the connecting rod 31 can also act as a lever. Through the lever effect of the connecting rod 31, the user can drive the first plug 7 to move upward with less force.

When the second pressing mechanism 4 needs to be installed, the rotating button 41 only needs to be pressed downward with force so that the second rotating shaft 194 can be snapped into the second rotating groove 43 to realize the rotational connection between the rotating button 41 and the outer wall of the main body 1.

[0085] Reference Fig.12 A limiting block 42 is provided on one end of the rotating knob 41 close to the second plug 8, and a clamping groove 421 is provided in the limiting block 42. The length direction of the clamping groove 421 extends along the length direction of the main body 1, and the two ends of the clamping groove 421 are respectively connected with the two pairs of side surfaces of the limiting block 42. A limiting groove 422 arranged in the same length direction as the clamping groove 421 is also provided in the limiting block 42, and the upper and lower sides of the limiting groove 422 are respectively connected with the bottom of the clamping groove 421 and the lower surface of the limiting block 42, and the two ends of the limiting groove 422 are respectively connected with the two pairs of side surfaces of the limiting block 42; wherein, a second clamping portion 81 passing through the limiting groove 422 and movably clamped with the clamping groove 421 is also provided at the upper end of the second plug 8.

[0086] Reference Fig.12 When the rotating button 41 is installed on the outer wall of the main body 1, the middle part of the rotating button 41 is rotatably connected to the outer wall of the main body 1, one end of the rotating button 41 is clamped with the upper end of the second plug 8, and the other end of the rotating button 41 is located above the first plug 7.

[0087] When it is necessary to use the sealing ring 10 in the primary connecting chamber 15 to separate the middle chamber 152 and the lower chamber 151 of the primary connecting chamber 15, it is only necessary to directly press the end of the rotating button 41 close to the first plug 7. During this process, the rotating button 41 will drive the second plug 8 to rise due to the action of the lever, thereby controlling the sealing ring 10 in the secondary connecting chamber 16 to separate the middle chamber 152 and the upper chamber 153 of the secondary connecting chamber 16. At this time, the water inlet and the water outlet of the secondary water outlet channel 12 are in a conductive state; when it is necessary to switch from the conductive state of the secondary water outlet channel 12 to the conductive state of the tertiary water outlet channel 13, it is only necessary to press the end of the rotating button 41 close to the second plug 8 again.

[0088] It should be noted that the working principle of the rotating button 41 and the connecting rod 31 is the same as that of the connecting rod 31 , and therefore, the rotating button 41 can also play a corresponding lever role, making the raising of the second plug 8 also more labor-saving.

[0089] Reference Figure 8 , a reset component 9 for resetting the first plug 7 and the second plug 8 is also provided in the body 1, and the reset component 9 includes a second elastic member 91 and a third elastic member 92; wherein, the second elastic member 91 is sleeved on the first plug 7 and the upper and lower ends are respectively abutted against the upper side of the top sealing ring 10 of the upper chamber 153. When the faucet stops supplying water, the first plug 7 can be reset downward by the second elastic member 91, so that when the faucet stops supplying water, the water inlet of the secondary water outlet channel 12 is connected to the water inlet of the body 1, and the primary water outlet channel 11 can be in a cut-off state; the third elastic member 92 is sleeved on the second plug 8 and the upper and lower ends are respectively abutted against the lower surface of the sealing ring 10 and the bottom of the lower chamber 151. When the faucet stops supplying water, the second plug 8 can be reset upward by the third elastic member 92, so that when the faucet stops supplying water, the water inlet of the secondary water outlet channel 12 is connected to the water inlet of the body 1, and the tertiary water outlet channel 13 can be in a cut-off state.

[0090] It should be noted that the water outlet type of each water outlet hole 21 connected to the secondary water outlet channel 12 is a type with lower water pressure, so that when the faucet supplies water, the water pressure of the pull head is low, avoiding a large amount of water splashing.

[0091] It should be noted that the elasticity of the second elastic member 91 and the third elastic member 92 is relatively small. When water is supplied inside the pull-out head, the elastic force of the second elastic member 91 and the third elastic member 92 is insufficient to enable the first plug 7 and the second plug 8 to overcome the water pressure for reset.

[0092] The implementation principle of a multifunctional pull-out head in the embodiment of the present application is:

[0093] When it is necessary to select different water outlet modes according to the needs, it is only necessary to control the water to flow out from the water outlet hole 21 of the corresponding function. At this time, the water can be controlled to flow out from one of the primary water outlet channel 11, the secondary water outlet channel 12 or the tertiary water outlet channel 13 by pressing the corresponding first pressing mechanism 3 and the second pressing. When water flows out from different water outlet channels, the water can flow out through the water outlet hole 21 connected to the corresponding water outlet channel.

[0094] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
