Description

Technical Field

[0001] The utility model belongs to the technical field of shower products, and in particular relates to an anti-drip shower head. Background Art

[0002] The shower head is an indispensable shower tool in a shower room, but the existing shower heads still have many defects.

[0003] The existing utility model patent with application number 202111261153 discloses a household intelligent anti-drip shower head, which pulls the connecting rod through a spring, and then pulls the plug through the connecting rod, so that when the water is flowing, the plug rises and the water flows smoothly out of the water outlet. When the water flow is closed, the plug is pressed down and water droplets cannot drip from the water outlet; and a filter net is provided to filter the water flow.

[0004] However, the above technical solution has the following problems: the filter is fixed inside the shower head. When the filter is blocked, the water flow is easily reduced and the filter is damaged and ineffective. If the filter is to be replaced, the entire shower head needs to be replaced, which causes waste. Furthermore, the shower head components are mostly connected through ropes and springs. The springs are prone to rust and lose elasticity when exposed to water. The rope may be corroded and broken by water after long-term use, which is not conducive to the long-term use of the shower head. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the internal filter device of the current drip-proof shower head is difficult to replace and is easily damaged as described in the above background technology. A new drip-proof shower head is proposed, in which the filter device is easy to replace and the internal parts are not easily damaged.

[0006] A technical solution adopted to achieve the above-mentioned purpose is a drip-proof shower head, the drip-proof shower head comprising:

[0007] An outer shell, wherein a water outlet hole is provided at the bottom of the outer shell;

[0008] An inner shell, wherein a cover is provided on the top of the inner shell, a water inlet is provided on the upper side wall of the inner shell, a water outlet is provided on the lower side wall of the inner shell, and an internal thread is provided on the upper inner wall of the inner shell;

[0009] A filter unit, the filter unit comprising a tank body and filter particles, the filter particles are placed inside the tank body, the outer wall of the tank body is provided with an external thread, the internal thread and the external thread match, and the bottom wall and the side wall of the tank body are provided with through holes;

[0010] A first leak-proof unit, the first leak-proof unit comprising a first elastic member and a piston plate, one end of the first elastic member is connected to the inner shell, and the other end of the first elastic member is connected to the piston plate;

[0011] The second anti-leakage unit comprises a second elastic member and a floating plate, one end of the second elastic member is connected to the floating plate, and the other end of the second elastic member is connected to the bottom of the inner shell.

[0012] In the above technical solution, the density of the float plate is less than the density of water. When water flows, the float plate is lifted due to buoyancy, and the water can flow out smoothly from the water outlet. When the water flow is closed, the float plate loses its buoyancy and under the pressure of the second elastic member, the float plate is tightly attached to the inner bottom wall of the outer shell to prevent water droplets from falling.

[0013] Furthermore, the through hole formed in the side wall of the tank body is connected to the water inlet.

[0014] In the above technical solution, the through holes provided in the side wall of the tank body play a filtering role, so that water can flow from the water inlet through the through holes into the interior of the tank body.

[0015] Furthermore, the water outlet communicates with the inner cavity of the inner shell and the inner cavity of the outer shell.

[0016] Furthermore, an elastic sleeve is fixed on the outer side of the bottom wall of the outer shell, and an opening at one end of the elastic sleeve is connected to the water hole.

[0017] In the above technical solution, when water is flowing, the opening at the other end of the elastic sleeve can be flushed open by the water flow, so that the water flow can be sprayed out smoothly. When the water flow is turned off, the opening at the other end of the elastic sleeve is automatically closed, thereby preventing the water flow from continuing to drip.

[0018] Furthermore, the inner shell is fixedly connected to the outer shell, and the inner shell is located inside the outer shell.

[0019] Furthermore, the inner shell is provided with a first recessed portion and a second recessed portion, and the second elastic member is partially located in the first recessed portion.

[0020] Furthermore, a sleeve is provided on the top of the floating plate, and a portion of the sleeve extends into the second recessed portion.

[0021] In the above technical solution, the sleeve can move freely up and down in the second recessed portion, and can prevent external water flow from entering the first recessed portion and the second recessed portion from the inside of the outer shell, thereby preventing the water flow from contacting the second elastic member.

[0022] Furthermore, the cover body is detachably connected to the inner shell body.

[0023] In the above technical solution, the cover body is detachably connected to the inner shell body. When the internal filter unit needs to be replaced, only the cover body needs to be removed to take out the failed filter unit.

[0024] Furthermore, the particle size of the filter particles is larger than the diameter of the through hole.

[0025] Furthermore, the bottom wall of the inner shell body is inclined downward from the center to the outside.

[0026] The advantages of the utility model are:

[0027] 1. After the filter unit of the utility model becomes ineffective after long-term use, it only needs to remove the cover, then rotate the tank to take out, install a new filter unit, buckle the cover and reuse it. The filter unit is easy to replace and disassemble, and there is no need to replace the entire shower head.

[0028] 2. Even if the filtering effect of the filtering unit of the utility model is weakened, there will be no clogging problem like the filter screen and other filtering devices, and the water flow will be prevented from suddenly decreasing.

[0029] 3. The utility model prevents water droplets from dripping from the water outlet after the water flow is turned off, thereby preventing the user from feeling uncomfortable, through the cooperation of the first anti-leakage unit and the second anti-leakage unit.

[0036] A drip-proof shower head is composed of an outer shell 1, an inner shell 2, a filter unit 3, a first leak-proof unit 4 and a second leak-proof unit 5.

[0037] The vertical cross-section of the outer shell 1 is an inverted "T" shape. The outer shell 1 is composed of a bottom cylindrical shell and a top cylindrical shell. The bottom cylindrical shell and the top cylindrical shell are connected. The interior is hollow to form a cavity, and the upper end is an opening. The cavity is connected to the outside through the opening. Water outlet holes 101 are evenly arranged at the bottom of the outer shell 1. An elastic sleeve 5 is fixed on the outer side of the bottom wall of the outer shell 1. The upper end opening of the elastic sleeve 5 is connected to the water outlet hole 101. The lower end opening of the elastic sleeve 5 is usually in a closed state. When water is passed, the lower end opening of the elastic sleeve 5 is in an open state. The above-mentioned elastic sleeve 5 is a prior art.

[0038] The vertical cross-section of the inner shell 2 is also an inverted "T" shape. The shape of the inner shell 2 is the same as that of the outer shell 1, except that the inner shell 2 is smaller than the outer shell 1, the inner shell 2 is hollow inside to form a cavity, a cover 201 is provided on the top of the inner shell 2, and the cover 201 is snap-fitted with the top opening of the inner shell 2, a water inlet 202 is provided on the upper side wall of the inner shell 2, a water outlet 203 is provided on the lower side wall of the inner shell 2, an internal thread is provided on the upper inner wall of the inner shell 2, the bottom wall of the inner shell 2 is recessed inward to form a first recessed portion 204 and a second recessed portion 205, and the bottom surface of the inner shell 2 is inclined downward from the center to the outside.

[0039] The bottom surfaces of the outer shell 1 and the inner shell 2 are circular, but not limited thereto. In other embodiments, the bottom surfaces may also be square, oval, or the like.

[0040] The filter unit 3 is composed of a tank body 301 and filter particles 302. The particle size of the filter particles 302 is larger than the diameter of the through hole 303. The filter particles 302 are filled in the tank body 301, and space is left between the filter particles 302 so that the filter particles 302 can move freely in the tank body 301. The lower outer wall of the tank body 301 is provided with an external thread, which cooperates with the internal thread provided on the upper inner wall of the inner shell 2. A plurality of through holes 303 are provided on the bottom wall and side walls of the tank body 301. The through holes 303 on the side walls of the tank body 301 are connected to the water inlet 202 provided on the upper side walls of the inner shell 2. The through holes 303 on the bottom wall of the tank body 301 connect the interior of the tank body 301 and the internal cavity of the inner shell 2.

[0041] The filter particles 302 may be spherical ceramic filter elements.

[0042] The first anti-leakage unit 4 is composed of a first elastic member 401 and a piston plate 402. The piston plate 402 is in a circular shape and is sleeved on the outside of the top cylindrical shell of the inner shell 2. One end of the first elastic member 401 is fixedly connected to the piston plate 402, and the other end of the first elastic member 401 is fixedly connected to the bottom cylindrical shell of the inner shell 2.

[0043] The second anti-leakage unit 5 is composed of a second elastic member 501 and a floating plate 502. One end of the second elastic member 501 is fixedly connected to the floating plate 502, and the other end of the second elastic member 501 is fixedly connected to the bottom wall of the first recessed portion 204 of the inner shell 2. A sleeve 503 is fixed on the top of the floating plate 502, and a portion of the sleeve 503 extends into the second recessed portion 205 to avoid direct contact between the second elastic member 501 and water, thereby extending the service life. The floating plate 502 can be made of plastic material and can be hollow inside.

[0044] The working process of the utility model is as follows: turn on the faucet switch, water flows in from the top opening of the outer shell 1, and the water pressure causes the piston plate 402 to move downward. When the piston plate 402 moves to below the water inlet 202, the water flows from the water inlet 202 through the through hole 303 into the inside of the tank body 301. At this time, impurities in the water flow are adsorbed by the filter particles 302, and the water flow continues to be discharged from the through hole 303 at the bottom of the tank body 301 into the internal cavity of the inner shell 2, and then enters the cavity between the outer shell 1 and the inner shell 2 from the water outlet 203. When water fills the cavity, the buoyancy is greater than the downward pressure of the second elastic member 501, and the floating plate 502 floats up under the action of the buoyancy, and the water flows out from the drainage hole 101 into the inside of the elastic sleeve 6. The impact of the water flow causes the lower opening of the elastic sleeve 6 to open, and finally the water flows out.

[0045] When the faucet is turned off, the water flow stops, and the water in the cavity between the outer shell 1 and the inner shell 2 is continuously discharged until the buoyancy of the float plate 502 is less than the downward pressure of the second elastic member 501. The float plate 502 fits against the inner side of the bottom wall of the outer shell 1, and the water cannot be discharged from the drain hole 101. In the absence of water flow impact, the lower opening of the elastic sleeve 6 is closed to further prevent water droplets from dripping. The first elastic member 401 pushes the piston plate 402 to rise, and the piston plate 402 moves to above the water inlet 202, and the remaining water in the water pipe can no longer enter the shower head.

[0046] The operation flow of replacing the filter unit of the utility model is as follows: dismantle the entire anti-drip shower head, open the cover body 201, screw out the tank body 301, screw in the new tank body 301, cover the cover body 201, and finally connect the anti-drip shower head to the water pipe.

[0047] Finally, it should be noted that this embodiment is only used to illustrate the present invention and does not limit the scope of the present invention. In addition, it should be understood that after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
