Description

Technical Field

[0001] The utility model relates to the technical field of bathroom products, in particular to a shower head that can be turned off and stopped immediately. Background Art

[0002] In the process of showering, there is often a situation where there is still residual water flowing out after the water is turned off. On the one hand, the water remaining in the water pipe will flow out after the valve is closed, and on the other hand, there will be residual water in the water outlet cavity of the shower structure. The generation of dripping water causes great discomfort to users, so a shower head with an instant stop and turn function came into being. For example, a shower head with an instant stop and turn function disclosed in Chinese patent CN209138908U is provided with an elastically openable and closed water outlet nozzle on the water outlet sleeve. When the water pressure value in the water outlet cavity is greater than the opening value of the water outlet nozzle, it opens and conducts the water outlet. When the water pressure value in the water outlet cavity is less than the opening value of the water outlet nozzle, the water outlet nozzle automatically resets and closes to close the water outlet so that the water remaining in the water outlet cavity cannot flow out, thereby realizing instant stop and turn. In this scheme, all water outlet nozzles need to be set to an openable and closable structure to ensure that the shower head will not drip after the water is turned off. However, due to the size of the water outlet, the size of the opening and closing structure on the water outlet nozzle is small, so the molding of the water outlet nozzle is difficult and the defective rate is high. At the same time, each shower head needs to have a customized water outlet cover due to different shapes or water outlet positions. The water outlet cover has low compatibility and high product development costs. Utility Model Content

[0003] The utility model discloses a shower head that can be turned on and off immediately, aiming to improve the problems of difficulty in forming a structure that can be turned on and off immediately and low compatibility.

[0004] The utility model adopts the following scheme:

[0005] A shower head that stops and starts immediately comprises a water outlet body and an elastic body, wherein the water outlet body is provided with a water inlet, a water inlet chamber, a water outlet chamber and a plurality of water outlet holes connected with the water outlet chamber; the elastic body is arranged in the water inlet chamber and is provided with a water storage chamber connected with the water outlet chamber, the outer wall of the elastic body abuts and seals with the inner wall of the water inlet chamber, so that the water inlet chamber is divided into a water inlet chamber and a water flow chamber; wherein the water inlet chamber is connected with the water inlet, and the water flow chamber is connected with the water outlet chamber; when the water is turned on, the elastic body is deformed under the action of water pressure to connect the water inlet chamber and the water flow chamber; when the water is turned off, the elastic body is reset to separate the water inlet chamber from the water flow chamber and to suck the remaining water in the water outlet chamber into the water storage chamber.

[0006] As a further improvement, the closed end of the elastic body is arranged toward the water inlet, and the open end thereof is used to communicate with the water outlet cavity.

[0007] As a further improvement, the cross-section of the elastomer is semi-circular or semi-elliptical, and the inner wall of the water inlet cavity is correspondingly provided with an arc surface that imitates the outer wall of the elastomer.

[0008] As a further improvement, a water passing plate fixedly connected to the water outlet body is arranged at the bottom of the elastomer. A first limiting portion is convexly provided along the periphery of the water passing plate. The elastomer correspondingly extends inwards to form a second limiting portion corresponding to the first limiting portion, and the first limiting portion and the second limiting portion are engaged and limited.

[0009] As a further improvement, water passing holes communicating with the water outlet cavity are provided on the water passing plate.

[0010] As a further improvement, the elastomer is made of soft rubber material.

[0011] As a further improvement, the water outlet body includes a rear cover, a water inlet member, a water outlet plate and a face cover. The rear cover is fitted and connected with the face cover. The water outlet holes are arranged on the face cover. The water inlet member and the water outlet plate are hermetically matched to form the water inlet cavity, and the water outlet plate and the face cover are hermetically matched to form the water outlet cavity.

[0012] As a further improvement, one end of the water inlet member is provided with a water inlet for connecting with a ball head. The other end is sequentially provided with a first surrounding wall, a second surrounding wall and a third surrounding wall along its center outwards. The water outlet plate is hermetically connected with the first, second and third surrounding walls to respectively form an installation space, a water passing channel and a water outlet channel. The elastomer is arranged in the installation space. A plurality of water passing grooves communicating with the water passing channel are arranged on the side surface of the first surrounding wall. A plurality of water outlet grooves communicating with the water outlet channel are arranged on the side surface of the second surrounding wall. The water outlet plate is respectively provided with a first water outlet and a second water outlet corresponding to the installation space and the water outlet channel.

[0013] As a further improvement, a plurality of water outlet grooves are arranged in an array along the circumferential direction of the second surrounding wall, and each of the water outlet grooves is obliquely arranged.

[0014] As a further improvement, one end of the rear cover is sleeved on the water inlet member and is buckled and limited with the water inlet member, and the other end is sleeved on the water outlet plate and is buckled and limited with the water outlet plate.

[0015] By adopting the above technical solutions, the following technical effects can be achieved by the present utility model:

[0016] 1. When the water is turned on in this application, the water flow enters from the water inlet and acts on the outer wall of the elastomer, so that the water storage cavity in the elastomer is squeezed. At this time, a water passage is formed between the outer wall of the elastomer and the inner wall of the water inlet cavity. The water flow flows into the water passage chamber from this water passage, and then flows through the water passage chamber to the water outlet cavity, and finally sprays from the water outlet hole communicating with the water outlet cavity to the user side. When the water is turned off, the water pressure in the water inlet chamber is insufficient. The elastomer resets under the action of its own elastic force, so that the outer wall of the elastomer abuts against the inner wall of the water inlet cavity. At this time, the water passage is closed, and the elastomer cuts off the water flow in the water inlet chamber. At the same time, a negative pressure is generated in the water storage cavity when the elastomer resets, so as to suck the remaining water in the water outlet cavity, ensuring that the remaining water will not directly drip. When the water is turned on next time, the remaining water in the water storage cavity enters the water outlet cavity under the action of water pressure and mixes with the water flow in the water outlet cavity. Among them, the remaining water is sprayed after mixing with warm water, which can avoid the discomfort caused by the too low temperature of the remaining water directly dripping on the user.

[0017] 2. In this application, only one elastomer needs to be arranged in the water inlet cavity to realize the sealing of the water inlet chamber and the suction of the remaining water in the water outlet cavity when the water is turned off, achieving the effect of stopping immediately when the water is turned off. In other words, the elastomer in this application plays the role of a one-way valve and stores the remaining water, thus avoiding the problem of dripping of the shower head after the valve is closed. The elastomer has a simple structure and is easy to form, and can be adapted to different shower head bodies, thereby reducing the manufacturing and assembly costs and ensuring the consistency and stability of product quality. In addition, the elastomer is arranged in the water inlet cavity, which has no influence on the shape and position layout of the water outlet hole, and thus can reduce the limitation on the appearance of the shower head body.

[0018] 3. The elastomer is made of soft rubber material, such as silica gel or rubber. The wall thickness of the elastomer is uniform, and its cross-section is semi-circular or semi-elliptical. The inner wall of the water inlet cavity is correspondingly provided with an arc surface that imitates the outer wall of the elastomer, so as to ensure that the outer wall of the elastomer can fit and seal with the inner wall of the water inlet cavity, ensuring the reliability of the seal.

Embodiment

[0030] Combine Figures 1 to 6The present embodiment provides a shower head that can be turned on and off immediately, comprising a water outlet body 1 and an elastic body 2, wherein the water outlet body 1 is provided with a water inlet 11, a water inlet chamber 12, a water outlet chamber 13 and a plurality of water outlet holes 14 communicated with the water outlet chamber 13; the elastic body 2 is arranged in the water inlet chamber 12, and is provided with a water storage chamber 21 communicated with the water outlet chamber 13, the outer wall of the elastic body 2 is abutted and sealed with the inner wall of the water inlet chamber 12, so that the water inlet chamber 12 is divided into a water inlet chamber 121 and a water passage chamber 122; wherein the water inlet chamber 121 is communicated with the water inlet 11, and the water passage chamber 122 is communicated with the water outlet chamber 13; when the water is turned on, the elastic body 2 is deformed under the action of water pressure to make the water inlet chamber 121 and the water passage chamber 122 conduct; when the water is turned off, the elastic body 2 is reset to separate the water inlet chamber 121 from the water passage chamber 122, and to suck the remaining water in the water outlet chamber 13 into the water storage chamber 21.

[0031] For example, when the water is turned on, the water flows in from the water inlet 11 and acts on the outer wall of the elastic body 2, so that the water storage chamber 21 in the elastic body 2 is squeezed. At this time, a water passage is formed between the outer wall of the elastic body 2 and the inner wall of the water inlet chamber 12, and the water flows from the water passage into the water passage chamber 122, and flows to the water outlet chamber 13 through the water passage chamber 122, and finally sprays to the user side from the water outlet hole 14 connected with the water outlet chamber 13. When the water is turned off, the water pressure in the water inlet chamber 121 is insufficient, and the elastic body 2 is reset under the action of its own elastic force, so that the outer wall of the elastic body 2 abuts against the inner wall of the water inlet chamber 12. At this time, the water passage is closed, and the elastic body 2 cuts off the water flow in the water inlet chamber 121. At the same time, when the elastic body 2 is reset, negative pressure is generated in the water storage chamber 21, thereby sucking the remaining water in the water outlet chamber 13 to ensure that the remaining water does not drip directly. When the water is boiled next time, the remaining water in the water storage chamber 21 enters the water outlet chamber 13 under the action of water pressure and mixes with the water flow in the water outlet chamber 13. The remaining water is sprayed out after mixing with warm water, which can avoid the discomfort caused by the remaining water with too low temperature directly dripping on the user.

[0032] It should be noted that, in this embodiment, only one elastomer 2 is provided in the water inlet chamber 12 to achieve the blocking of the water inlet chamber 121 and the absorption of the residual water in the water outlet chamber 13 when the water is turned off, so as to achieve the effect of turning off and stopping. In other words, the elastomer 2 of this embodiment plays the role of a one-way valve and stores the residual water, thereby avoiding the problem of dripping from the shower after the valve is closed. The elastomer 2 has a simple structure and is easy to form. It can be adapted to different shower bodies, thereby reducing the cost of manufacturing and assembly and ensuring the consistency and stability of product quality. In addition, the elastomer 2 is provided in the water inlet chamber 12, which has no effect on the shape and position layout of the water outlet hole 14, thereby reducing the restrictions on the appearance of the shower body.

[0033] In a preferred embodiment, the closed end of the elastomer 2 faces the water inlet 11, and its open end is used to communicate with the water outlet cavity 13. Further, the elastomer 2 is made of a soft rubber material, such as silicone or rubber. The wall thickness of the elastomer 2 is uniform, and its cross-section is semi-circular or semi-elliptical. An arc surface 123 conforming to the outer wall of the elastomer 2 is correspondingly provided on the inner wall of the water inlet cavity 12, so as to ensure that the outer wall of the elastomer 2 can fit and seal with the inner wall of the water inlet cavity 12, ensuring the reliability of the seal.

[0034] In one implementation, a water passing plate 3 fixedly connected to the water outlet body 1 is arranged at the bottom of the elastomer 2. A first limiting portion 31 protrudes along the periphery of the water passing plate 3. The elastomer 2 correspondingly extends inward to form a second limiting portion 22 corresponding to the first limiting portion 31, and the first limiting portion 31 and the second limiting portion 22 are engaged and limited. Wherein, a water passing hole 32 communicating with the water outlet cavity 13 is provided on the water passing plate 3. The first limiting portion 31 is arranged around the periphery of the water passing plate 3, and the second limiting portion 22 extends inward along the periphery of the bottom of the elastomer 2. During installation, the water passing plate 3 is first fixed to the water outlet body 1, which can be fixed by welding or gluing, etc., and then the elastomer 2 is sleeved, and the second limiting portion 22 is engaged with the first limiting portion 31, so that the elastomer 2 is limited. At this time, the first limiting portion 31 and the second limiting portion 22 are engaged and pressed tightly, so that the periphery of the water passing plate 3 can be sealed, thus ensuring the tightness of the water storage cavity 21.
