Description

Shower bath

Technical Field

The present invention relates to bathroom technology, and is especially one kind of shower.

Background

A shower kit typically includes a shower, a shower head, a top shower and a down outlet pipe. The hot water supply pipe and the cold water supply pipe are both connected to the shower, and the shower can selectively convey the hot water output by the hot water supply pipe and the cold water output by the cold water supply pipe to the shower head, the top shower and the lower water outlet pipe after being mixed.

Some existing showers can directly add the shower gel into the waterway communicated with the shower head, so that the shower gel is mixed in water sprayed by the shower head, and a user can take the shower gel more conveniently during bathing. However, the design disadvantage is also very obvious, firstly, the shower gel is directly added into the water channel to cause the water channel to be polluted by the shower gel, and secondly, the shower gel is added into water to dilute the shower gel to cause unobvious foaming effect due to the large water outlet amount of the shower head, so that the cleaning effect of the shower gel is reduced.

In the present embodiment, as shown in fig. 8, the surface of the first elastic cover 2151 facing the first groove 2111 and the inner surface of the first groove 2111 enclose a first volume-variable chamber 2101. When the driving motor 241 drives the eccentric wheel 246 to rotate, the eccentric wheel 246 drives the first connecting portion 2152 of the first piston 215 to reciprocate away from the first groove 2111 and close to the first groove 2111 through the first connecting rod 214. When the first connection portion 2152 approaches the first groove 2111, the first connection portion 2152 presses the first elastic cover 2151 in a direction approaching the first groove 2111 so that the volume of the first variable-volume chamber 2101 becomes smaller; when the first connection portion 2152 is away from the first recess 2111, the first connection portion 2152 pulls the first elastic cover 2151 away from the first recess 2111 so that the volume of the first variable volume chamber 2101 becomes larger.

The second housing 221 is provided with a second liquid inlet passage 2214 and a second liquid outlet passage 2215. The second inlet passage 2214 and the second outlet passage 2215 each extend from the bottom of the second groove 2211 toward the opening direction of the second groove 2211. The walls of the second liquid inlet channel 2214 and the second liquid outlet channel 2215 are protruded from the bottom wall of the second groove 2211. The second inlet passage 2214 and the second outlet passage 2215 may be each provided as a passage having a circular cross section. A second liquid inlet 2212 and a second liquid outlet 2213 are also arranged on the bottom wall of the second groove 2211.

The third one-way valve 226 is configured to allow fluid to flow only from the end of the second fluid intake passage 2214 adjacent to the second fluid intake bore 2212 to the end of the second fluid intake passage 2214 facing away from the second fluid intake bore 2212. The fourth one-way valve 227 is configured such that fluid can flow only from the end of the second liquid outlet passage 2215 facing away from the second liquid outlet hole 2213 to the end of the second liquid outlet passage 2215 adjacent to the second liquid outlet hole 2213.

In this embodiment, as shown in fig. 8, the surface of the second elastic cover 2251 facing the second groove 2211 encloses the second volume-variable chamber 2201 with the inner surface of the second groove 2211. When the driving motor 241 drives the eccentric wheel 246 to rotate, the eccentric wheel 246 drives the second connecting part 2252 of the second piston 215 to reciprocate away from the second groove 2211 and close to the second groove 2211 through the second connecting rod 214. As the second connection 2252 approaches the second groove 2211, the second connection 2252 presses the second elastic cover 2251 in a direction approaching the second groove 2211 so that the volume of the second variable-volume chamber 2201 becomes smaller; as the second connection 2252 moves away from the second groove 2211, the second connection 2252 pulls the second elastic cover 2251 away from the second groove 2211 such that the volume of the second variable volume chamber 2201 increases. Thus, as the eccentric 246 rotates, the volume of the second variable volume chamber 2201 alternately increases and decreases.

When the volume of the second volume-variable chamber 2201 becomes larger, the second volume-variable chamber 2201 has negative pressure therein, and fluid sequentially enters the second volume-variable chamber 2201 through the second liquid inlet 2212 and the second liquid inlet passage 2214; when the volume of the second volume-variable chamber 2201 becomes smaller, positive pressure is provided in the second volume-variable chamber 2201, and the fluid in the second volume-variable chamber 2201 is sequentially discharged through the second liquid outlet passage 2215 and the second liquid outlet hole 2213.

Two ends of the drain pipe 282 are respectively connected with the first liquid outlet 2113 of the first liquid pumping assembly 21 and the first inlet 2831 of the three-way pipe 283, and the second inlet 2832 of the three-way pipe 283 is communicated with the detergent outlet 262 of the storage cavity 260 of the storage box 26. Two ends of the liquid pumping pipe 284 are respectively connected with a first outlet 2833 of the three-way pipe 283 and a second liquid inlet 2212 of the second liquid pumping assembly 22. One end of the drain pipe 285 is connected to the second outlet 2213 of the second pumping unit 22, and the other end of the drain pipe 285 is connected to the bubbling unit 23.

As shown in fig. 8 and 11, the driving mechanism drives the first liquid pumping assembly 21 and the second liquid pumping assembly 22 to operate simultaneously. When the first pumping unit 21 is operated, water in the water mixing channel 115 of the valve body 11 is pumped out through the pumping pipe 281, and then is injected into the first inlet 2831 of the tee 283 through the drain pipe 282. When the second pumping assembly 22 operates, the fluid at the first outlet 2833 of the three-way pipe 283 is pumped through the pumping pipe 284, so that the negative pressure is generated at the first outlet 2833 of the three-way pipe 283, and as the flow rate of the fluid conveyed by the first pumping assembly 21 is smaller than that of the fluid conveyed by the second pumping assembly 22, the cleaning agent in the storage cavity 260 of the storage box 26 can be sucked into the three-way pipe 283, the cleaning agent and the water conveyed into the three-way pipe 283 by the first pumping assembly 21 are mixed into a mixed liquid in the three-way pipe 283, the mixed liquid enters the second pumping assembly 22 along the pumping pipe 284, and the mixed liquid is conveyed into the foaming assembly 23 by the second pumping assembly 22 through the liquid draining pipe 285.

As shown in fig. 9, 12, 13, the foaming assembly 23 includes a cavity 231 and a foaming mechanism 232. A bubbling chamber 230 is disposed within the chamber 231. The cavity 231 includes an inner housing 233 and an outer housing 234. The inner housing 233 includes side plates 2332 and a bottom plate 2331. The side plate 2332 is configured in a cylindrical structure, and the bottom plate 2331 is covered on one end of the side plate 2332. The outer cover 234 overlies an end of the side plate 2332 facing away from the bottom plate 2331. The cover 234 and base plate 2331 enclose a bubbling chamber 230. The bottom plate 2331 of the inner housing 233 is provided with a mixed liquid inlet 237 and a bubbling port 238, and both the mixed liquid inlet 237 and the bubbling port 238 are communicated with the bubbling chamber 230. The mixed liquor inlet 237 is connected to an end of the drain pipe 285 facing away from the second outlet bore 2213 of the second drawing assembly 22. The outer cover 234 is provided with an air inlet 239 and a shaft hole 2341, the air inlet 239 communicates with the bubbling chamber 230, the shaft hole 2341 penetrates the outer cover 234, and the air inlet 239 is provided at one side of the shaft hole 2341. The first shaft 248 extends into the bubbling chamber 230 through the shaft hole 2341.

As shown in fig. 13, a bubbling mechanism 232 is disposed within the bubbling chamber 230. The bubbling mechanism 232 includes a first bubbling gear 235 and a second bubbling gear 236. The first bubble gear 235 is sleeved on the first rotating shaft 248. The second bubbling gear 236 is rotatably coupled to the outer cover 234 and the inner cover 233, respectively, and the second bubbling gear 236 may be pivotally coupled to the outer cover 234 and the inner cover 233. The first bubbling gear 235 and the second bubbling gear 236 are engaged with each other.

As shown in fig. 7, the first shaft 248 of the driving mechanism can also drive the first bubbling gear 235 and the second bubbling gear 236 to rotate simultaneously. The cavity 231, the first bubbling gear 235 and the second bubbling gear 236 form a gear pump-like structure, and the first bubbling gear 235 and the second bubbling gear 236 form a negative pressure area and a positive pressure area in the bubbling cavity 230 when rotated. That is, fluid is pumped from one side of the first and second bubbling gears 235, 236 to the other side as the first and second bubbling gears 235, 236 are rotated toward each other within the bubbling chamber 230, such that a negative pressure region and a positive pressure region are formed within the bubbling chamber 230, from which fluid flows to the positive pressure region. The pressure in the negative pressure region is less than the standard atmospheric pressure, and the pressure in the positive pressure region is greater than the standard atmospheric pressure. Both the mixed liquor inlet 237 and the air inlet 239 are connected with a negative pressure zone, and the bubble outlet 238 is connected with a positive pressure zone.

The driving mechanism drives the first drawing liquid component 21 and the second drawing liquid component 22 to rotate when driving the first drawing liquid gear 235 and the second drawing liquid component 236 to rotate, the second drawing liquid component 22 injects the mixed liquid of the cleaning agent and the water into the foaming cavity 230 from the mixed liquid inlet 237 through the liquid outlet 285, and because of the negative pressure area at the air inlet 239, the outside air can be sucked into the foaming cavity 230 from the air inlet 239, and the mixed liquid and the air in the foaming cavity 230 are uniformly mixed by the first drawing liquid gear 235 and the second drawing liquid gear 236 when rotating to generate foams, and the foams are output from the foaming cavity 230 from the foam outlet 238 in the positive pressure area. Thus, the user can receive the foam from the foam outlet 238 and then use it for cleaning the body, conveniently and quickly.

In one exemplary embodiment, as shown in fig. 10, the diameter of the second elastic cover 2251 of the second piston 215 is greater than the diameter of the first elastic cover 2151 of the first piston 215.

Thus, the volume change of the second variable volume chamber 2201 is greater than the volume change of the first variable volume chamber 2101, and the flow rate at which the second pumping assembly 22 pumps out during reciprocation of the second piston 215 is greater than the flow rate at which the first pumping assembly 21 pumps out during reciprocation of the first piston 215.

The ratio of water to detergent mixing can also be controlled by adjusting the flow rates of the first and second pump assemblies 21, 22 by changing the size relationship between the first and second elastic covers 2151, 2251. The smaller the ratio of the diameters of the second elastic cover 2251 and the first elastic cover 2151, the smaller the ratio of the cleaning agent to water, and the thinner the cleaning agent in the mixed liquid.

In an exemplary embodiment, the stroke of the second piston 215 is greater than the stroke of the first piston 215. For example, eccentric 246 may be positioned more toward second piston 215 such that second piston 215 may have a greater stroke.

When the stroke of the second piston 215 is larger than the stroke of the first piston 215, the volume change amount of the second volume-variable chamber 2201 is larger than the volume change amount of the first volume-variable chamber 2101, and the flow rate of the second pumping unit 22 pumping during the reciprocating motion of the second piston 215 is larger than the flow rate of the first pumping unit 21 pumping during the reciprocating motion of the first piston 215.

The ratio of the mixing of the water and the cleaning agent can also be controlled by adjusting the flow rates of the first and second pumping assemblies 21, 22 by changing the ratio of the stroke of the first piston 215 to the stroke of the second piston 215. The greater the ratio of the travel of the first piston 215 to the travel of the second piston 215, the less the ratio of detergent to water, and the more dilute the detergent in the mixture.

In one illustrative embodiment, as shown in FIG. 15, the area of first inlet 2831 of tee 283 is larger than the area of second inlet 2832.

The larger the area of the first inlet 2831 and the smaller the area of the second inlet 2832, the smaller the ratio of detergent to water and the more dilute the detergent in the mixed liquor. The ratio of the area of the first inlet 2831 to the area of the second inlet 2832 may be 8:2 or 7:3.

In one illustrative embodiment, the diameter of the first frothing gear 235 is greater than the diameter of the second frothing gear 236.

The second rotating shaft 247 drives the first foaming gear 235 to rotate, the first foaming gear 235 drives the second foaming gear 236 to rotate, and the second foaming gear 236 can rapidly stir mixed liquid and air due to the fact that the diameter of the first foaming gear 235 is larger than that of the second foaming gear 236, and the second foaming gear 236 can rapidly stir mixed liquid and air, so that foam is more dense.

In an exemplary embodiment, as shown in fig. 9, the first cylinder 210 further includes a first fixing seat 213. May be constructed in a generally cylindrical structure. The first fixing base 213 is disposed between the first housing 211 and the first elastic cover 2151 and is located in the first groove 2111, and an outer peripheral surface of the first fixing base 213 abuts against an inner peripheral surface of the first groove 2111. The first fixing seat 213 is provided with a first limiting plate 2131, and the first limiting plate 2131 is further provided with a second through hole 2132 and a third through hole 2133.

Because the first one-way valve 216 is disposed in the first liquid inlet channel 2114, fluid can flow into the first liquid inlet channel 2114 from the first liquid inlet hole 2112 and then flow into the second through hole 2132 of the first limiting plate 2131 through the gap between the elastic tube 41 of the first one-way valve 216 and the first liquid inlet channel 2114; when the fluid flows reversely, that is, when the fluid flows from the second through hole 2132 of the first limiting plate 2131 to the first liquid inlet hole 2112, the elastic tube 41 of the first check valve 216 is opened, so that the elastic tube 41 is tightly attached to the inner wall of the first liquid inlet channel 2114, and the first check valve 216 blocks the fluid from flowing to the first liquid inlet hole 2112.

Because the second one-way valve 217 is arranged in the first liquid outlet channel 2115, fluid can flow into the first liquid outlet channel 2115 from the third through hole 2133 of the first limiting plate 2131 and then flow into the first liquid outlet hole 2113 through the gap between the elastic cylinder 41 of the second one-way valve 217 and the first liquid outlet channel 2115; when the fluid flows reversely, that is, when the fluid flows from the first liquid outlet hole 2113 to the third through hole 2133, the elastic tube 41 of the second check valve 217 opens so that the elastic tube 41 is closely attached to the inner wall of the first liquid outlet channel 2115, and the second check valve 217 blocks the fluid from flowing in the direction of the third through hole 2133.

Because the third one-way valve 226 is disposed in the second liquid inlet passage 2214, fluid can flow into the second liquid inlet passage 2214 from the second liquid inlet hole 2212, and then flow into the fourth hole 2232 of the second limiting plate 2231 through a gap between the elastic tube 41 of the third one-way valve 226 and the second liquid inlet passage 2214; when the fluid flows reversely, that is, the fluid flows from the fourth through hole 2232 of the second limiting plate 2231 to the second liquid inlet hole 2212, the elastic cylinder 41 of the third one-way valve 226 is opened so that the elastic cylinder 41 is closely attached to the inner wall of the second liquid inlet channel 2214, and the third one-way valve 226 blocks the fluid from flowing to the second liquid inlet hole 2212.
