Description

[0002] Currently, there are many technologies on the market that have the function of mixing cleaning liquid and water to discharge water, but most of the implementation methods are relatively simple, only through the basic inlet and outlet design of the external cleaning liquid cavity, lack of in-depth research on the mixing effect, resulting in unsatisfactory foam effect. In order to improve the foaming effect, some technologies try to introduce impeller stirring, but this not only increases the cost, but may also cause the impeller to fail due to dirt accumulation caused by long-term use. Another common method is to use the Venturi effect to form a negative pressure at the cleaning liquid addition end, attracting the cleaning liquid into the mixing channel to mix with water, thereby achieving foaming. However, these methods all have their own limitations and need further optimization and improvement. Summary of the invention

[0016] From the above description of the various embodiments of the present invention, it can be seen that, compared with the prior art, the various embodiments of the present invention have the following advantages:

[0017] Beneficial effects:

[0018] In the first technical solution and related embodiments, the effective mixing and uniform output of the cleaning liquid and water are achieved through the structure of the first flow channel and the second flow channel and the position design of the first water outlet and the first liquid outlet. The cavity is a component for storing the cleaning liquid. The designed liquid injection port is convenient for the injection of the cleaning liquid. The water flows into the cavity from the water inlet through the first water outlet to mix with the cleaning liquid and flows out from the first liquid outlet. The different apertures of the first water outlet and the first liquid outlet help to adjust the flow ratio of water and the mixed liquid, thereby controlling the mixing ratio. The first-level flow channel introduces the water flow through the first water inlet. The second water outlet is displaced from the first water inlet along the water flow direction to ensure the introduction of the water flow, and the water flow is attenuated by the dislocation structure, which helps to enhance the effect of the water flow and the mixed liquid coming out of the first liquid outlet. Specifically, the second-level flow channel is connected to the first liquid outlet, so that the mixed liquid can enter the second-level flow channel and mix with the attenuated water flow again. Finally, the effectively mixed clean mixed liquid is uniformly output through the liquid outlet. When the cleaning liquid is completely used up, the water flowing into the cavity is clean water, so the automatic cleaning cavity function can be realized, eliminating the inconvenient cleaning experience caused by the residual cleaning liquid.

[0019] In the second technical solution and related embodiments, the cleaning liquid mixed liquid is mixed again with the attenuated water flow entering from the second water outlet in the second-stage flow channel, and flows to the liquid outlet through the second liquid outlet through the liquid mixing chamber. By providing the liquid mixing chamber in the flow channel, and making the second liquid outlet of the second-stage flow channel face the side wall of the liquid mixing chamber, the mixed liquid flow is decelerated again after flowing through the second-stage flow channel, the mixing time is extended, and further mixing is performed in the liquid mixing chamber, ensuring that the mixed liquid is more uniform and stable.

[0020] In the third technical solution and related embodiments, the shape and layout of the first water inlet and the second water outlet are used to achieve effective attenuation of the water flow, ensuring the smooth flow of the water flow, so that the water flow entering from the second water outlet can be fully mixed again with the mixed liquid entering the second-level flow channel through the first liquid outlet in the second-level flow channel, and the mixing process is more uniform.

[0021] In the fourth technical solution and related embodiments, by optimizing the cross-sectional area ratio of the second water outlet and the first water inlet, combining the staggered distribution of the first water inlet and the second water outlet and the design of the horizontal and vertical runway-type channels, the smooth flow and mixing of the water can be achieved, effectively avoiding the generation of whistling sounds and ensuring the smoothness of the jet.

[0022] In the fifth technical solution and related embodiments, the ratio between the aperture of the first liquid port and the aperture of the first water port is set to 1.6. If the difference between the two apertures is too large, the water jet entering from the first water port will show an extremely high single-column intensity, while in contrast, the mixed liquid jet output from the first liquid port will appear to have a weaker and more dispersed spray force. In this case, the cleaning mixed liquid in the cavity will be output too quickly, resulting in a too short dilution time for the cleaning liquid and water, thereby affecting the cleaning effect and shortening the overall use time. By setting the aperture ratio of the first liquid port to the aperture ratio of the first water port to 1.6, it can be ensured that the cleaning liquid obtains a more reasonable dilution concentration, which not only ensures sufficient cleaning force, but also extends the effective use time of the cleaning mixed liquid, thereby improving the overall cleaning effect and the efficiency of the device.

[0023] In the sixth technical solution and related embodiments, the number of liquid outlets is several, and the aperture of each liquid outlet is greater than 0.5 mm. This design balances the jet intensity and the amount of foaming to achieve a more ideal cleaning effect. By increasing the number of liquid outlets and appropriately expanding the aperture of each liquid outlet, the strength of the jet is reduced and splashing is avoided. At the same time, the amount of foaming remains at a high level. In addition, since the flow rate of each liquid outlet is relatively uniform, the detergent in the same volume cavity can be used more persistently, reducing the cleaning cost.

[0024] In the seventh technical solution and related embodiments, the liquid outlet can be further upgraded so that it can be connected to a bubbler. The bubbler is used to further refine the foam so that the foam is delicate and the jet is soft.

[0025] In the eighth technical solution and related embodiments, the body forms a cavity and a flow channel through the cooperation of the main component, the water inlet tray and the water outlet tray.

[0026] In the ninth technical solution and related embodiments, the synergistic effect of the flip button, the first elastic member, the cover plate, and the second elastic member enables the user to easily and quickly complete the operation of adding cleaning liquid while maintaining the integrity and aesthetics of the device's appearance. Specifically, when the user needs to add cleaning liquid, he only needs to gently press the flip button, and the contact between the flip button and the cover plate will be released, and the first elastic member will begin to store energy. At the same time, the second elastic member quickly releases its stored energy and automatically pops up the cover plate, thereby exposing the liquid injection port for the cleaning liquid. After adding the cleaning liquid, the user simply presses the cover plate back into place so that it re-engages with the flip button. At this point, the device will return to the appearance of an integrated device, maintaining the overall integrity and having a beautiful design.

[0027] In the tenth technical solution and related embodiments, the output device can not only output the mixed cleaning liquid, but also provide a conventional shower water outlet function, thereby improving the practicality and functionality of the output device.

[0028] In the eleventh technical solution and related embodiments, the shower head adopts the above-mentioned cleaning liquid output device and is detachably connected to the brush assembly, so that the type of the brush assembly can be easily replaced, making it more applicable to different scenarios.

[0043] In the claims, specification and the above drawings of the present invention, unless otherwise clearly defined, if the term "fixed connection" or "fixed connection" is used, it should be understood in a broad sense, that is, any connection method without a displacement relationship and relative rotation relationship between the two, that is to say, including non-detachable fixed connection, detachable fixed connection, integrated connection and fixed connection through other devices or elements.

[0044] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0045] In this embodiment, in order to combine with the drawings and for the convenience of introduction, it is stipulated that the first direction X is the direction from top to bottom, the second direction Y is the direction from front to back, and the third direction Z is the left and right direction, but this does not mean that the directional limitation of this patent is limited. In this patent, as long as the first direction X, the second direction Y and the third direction Z are perpendicular (orthogonal) to each other, it will be fine.

[0046] See also Figures 1 to 4 ,like Figure 1 As shown, a cleaning liquid output device includes a main body 100, and the main body 100 includes a main part, a water inlet tray 2 and a water outlet tray 3 which are detachably fixed to each other in sequence.

[0047] like Figure 1As shown, the liquid injection port 11 and the cavity 10 are formed in the main part, and the main part, the water inlet tray 2 and the water outlet tray 3 cooperate to form a flow channel. The flow channel includes a water inlet 20, a first-stage flow channel 21, a second-stage flow channel 22 and a liquid mixing chamber 31 that are connected in sequence, and a liquid outlet 32 ​​for outputting the mixed liquid.

[0048] Subject 1, such as Figures 1 to 4 As shown, it includes a flip button 14, a first elastic member 16, a cover plate 15 and a second elastic member 17. Figure 1 As shown, the main part is a shower head with a handle, and a cavity 10 is provided inside for accommodating a mixture of cleaning liquid and water. The cavity 10 is provided with a liquid injection port 11 for injecting cleaning liquid, a first water outlet 12 and a first liquid outlet 13, the liquid injection port 11 is located at the upper end of the cavity 10 along the first direction, the first water outlet 12 and the first liquid outlet 13 are both located at the lower end of the cavity 10 along the first direction, and are arranged left and right along the third direction.

[0049] Flip button 14, such as Figure 1 and Figure 4 As shown, it is located at one end of the main part away from the handle along the third direction, and the flip button 14 is a push button.

[0050] The first elastic member 16, such as Figure 1 As shown, it is installed between the flip cover button 14 and the main part. Specifically, the first elastic member 16 is a spring.

[0051] Cover plate 15, such as Figure 1 and Figure 4 As shown, it is located at the upper end of the main part along the first direction, and the cover plate 15 is rotatably connected to the main part. Specifically, the cover plate 15 is connected to the main part using a rotating pin. The cover plate 15 covers the liquid injection port 11 and is engaged with the flip button 14 to close the liquid injection port 11. Specifically, the cover plate 15 is provided with a hook 18, and the flip button 14 is provided with a slot 19 matching the hook 18.

[0052] The second elastic member 17 is installed between the cover plate 15 and the body 100, and stores energy when the cover plate 15 covers the injection port 11. Specifically, a convex column is provided inside the cavity 10 to clamp the second elastic member 17, and the cover plate 15 is provided with a convex block adapted to the injection port 11 to block the injection port 11 and abut the second elastic member 17.

[0053] like Figure 4 As shown, by pressing the flip button 14, the cover plate 15 and the flip button 14 are out of contact, the first elastic member 16 stores energy, and the second elastic member 17 releases energy to lift the cover plate 15, and the flip button 14 returns to its initial position under the action of the first elastic member 16. At this time, the liquid injection port 11 is exposed, and the cleaning liquid can be injected.

[0054] In this embodiment, the synergistic effect of the flip button 14, the first elastic member 16, the cover plate 15 and the second elastic member 17 enables the user to easily and quickly complete the operation of adding cleaning liquid while maintaining the integrity and aesthetics of the device's appearance. Specifically, when the user needs to add cleaning liquid, he only needs to gently press the flip button 14, and the contact between the flip button 14 and the cover plate 15 will be released, and the first elastic member 16 will begin to store energy. At the same time, the second elastic member 17 quickly releases its stored energy and automatically pops up the cover plate 15, thereby exposing the liquid injection port 11 for the cleaning liquid. After adding the cleaning liquid, the user only needs to simply press the cover plate 15 back into place so that it is re-fastened with the flip button 14. At this time, the device will return to the appearance of an integrated device, maintaining the overall integrity and having a beautiful design.

[0055] Water inlet tray 2, such as Figures 1 to 3 As shown, it is detachably fixed to the main part. The main part and the water inlet tray 2 cooperate to form a water inlet 20, a first-level flow channel 21 and a second-level flow channel 22 that are connected in sequence. The first water inlet 12 is connected to the water inlet 20, and the first-level flow channel 21 is provided with a first water inlet 23 connected to the water inlet 20 and a second water inlet 24 that is offset from the first water inlet 23 along the water flow direction. The second water inlet 24 is used to introduce the water flow into the second-level flow channel 22. The second-level flow channel 22 is connected to the first liquid inlet 13 so that the mixed liquid is introduced and mixed with the water flow again, and then output through the liquid outlet 32.

[0056] Specifically, Figure 3 As shown, the cross section of the first water inlet 23 is runway-shaped and extends in a second direction perpendicular to the first direction, the cross section of the second water outlet 24 is runway-shaped and extends in the first direction, and there are two second water outlets 24, which are respectively located on both sides of the first water inlet 23 along the first direction and are offset from the first water inlet 23. Through the shape and layout of the first water inlet 23 and the second water outlet 24, effective attenuation of the water flow is achieved, and the smooth flow of the water flow is ensured, so that the water flow entering from the second water outlet 24 can be fully mixed again in the second flow channel 22 with the mixed liquid entering the second-stage flow channel 22 through the first liquid outlet 13, and the mixing process is more uniform.

[0057] In this embodiment, the total cross-sectional area of ​​the two second water ports 24 is 1.5 times the cross-sectional area of ​​the first water inlet 23. By optimizing the cross-sectional area ratio of the second water ports 24 to the first water inlet 23, combined with the staggered distribution of the first water inlet 23 and the second water ports 24 and the design of the horizontal and vertical runway-type channels, the water flow is stabilized and mixed, the whistling sound is effectively avoided, and the smoothness of the jet is ensured.

[0058] Among them, after the water flows into the first-stage flow channel 21, it enters the cavity 10 through the first water outlet 12, mixes with the cleaning liquid inside the cavity 10, and then flows out from the first liquid outlet 13. The aperture of the first water outlet 12 is smaller than the aperture of the first liquid outlet 13. Specifically, the ratio of the aperture of the first liquid outlet 13 to the aperture of the first water outlet 12 is 1.6. If the difference between the two apertures is too large, the water jet entering from the first water outlet 12 will show a very high single-column intensity, while in contrast, the mixed liquid jet output from the first liquid outlet 13 will appear to have a weaker and more dispersed spray force. In this case, the clean mixed liquid in the cavity 10 will be output too quickly, resulting in a too short dilution time of the cleaning liquid and water, thereby affecting the cleaning effect and shortening the overall use time. By setting the aperture ratio of the first liquid outlet 13 to the first water outlet 12 to 1.6, it can be ensured that the cleaning liquid obtains a more reasonable dilution concentration, which not only ensures sufficient cleaning power, but also extends the effective use time of the cleaning mixture, thereby improving the overall cleaning effect and the efficiency of the device.

[0059] The water outlet tray 3 cooperates with the water inlet tray 2 to form a liquid mixing chamber 31. Specifically, the water outlet tray 3 is provided with a receiving groove in the middle, and the receiving groove cooperates with the water inlet tray 2 to form the liquid mixing chamber 31.

[0060] The water outlet tray 3 is detachably fixed to the water inlet tray 2. The liquid mixing chamber 31 is located after the second flow channel and is connected to the liquid outlet 32. The second-stage flow channel 22 is provided with a second liquid outlet 25, and the second liquid outlet 25 faces the side wall of the liquid mixing chamber 31. Specifically, a groove is provided at the lower end of the second-stage flow channel 22 along the first direction, and a plurality of second liquid outlets 25 are arranged along the circumferential groove wall of the groove, and the groove protrudes toward the direction of the receiving groove.

[0061] The liquid outlet 32 ​​is located at the water outlet tray 3. Specifically, the liquid outlet 32 ​​is located below the accommodating tank. The cleaning liquid mixture flows to the side wall of the mixing liquid chamber 31 through the second liquid outlet 25, and then converges and flows out from the liquid outlet 32. The cleaning liquid mixture is mixed again with the attenuated water flow entering from the second water outlet 24 in the second-stage flow channel 22, and flows to the liquid outlet 32 ​​through the mixing liquid chamber 31 through the second liquid outlet 25. By arranging the mixing liquid chamber 31 in the flow channel and making the second liquid outlet 25 of the second-stage flow channel 22 face the side wall of the mixing liquid chamber 31, the mixed liquid flow is decelerated again after flowing through the second-stage flow channel 22, and the mixing time is extended. Further mixing is performed in the mixing liquid chamber 31, ensuring that the mixed liquid is more uniform and stable.

[0062] In this embodiment, the number of liquid outlets 32 is several, preferably 40, and the aperture of the liquid outlet 32 ​​is greater than 0.5 mm. This design balances the jet intensity and the amount of foaming to achieve a more ideal cleaning effect. By increasing the number of liquid outlets 32 and appropriately enlarging the aperture of each liquid outlet 32, the strength of the jet is reduced to avoid splashing. At the same time, the amount of foaming remains at a high level. In addition, since the flow rate of each liquid outlet 32 ​​is relatively uniform, the detergent in the same volume chamber 10 can be used more persistently, reducing the cleaning cost.

[0063] In other embodiments, the liquid outlet 32 ​​is suitable for connecting a bubbler to further refine the foam. In this embodiment, the liquid outlet 32 ​​can be further upgraded to enable it to connect a bubbler. The bubbler is used to further refine the foam so that the foam is delicate and the jet is soft.

[0064] The water outlet tray 3 is also provided with a plurality of water outlets 33, which are connected to the water inlet 20, and are arranged circumferentially around the liquid outlet 32. Specifically, the water flow from the water inlet 20 flows through the water outlet 33 from an independent water passage, and the opening and closing of the water passage is controlled by the switch valve on the main part. How the switch valve specifically controls the water passage does not belong to the content of this application and will not be repeated here. The output device can not only output the mixed cleaning liquid, but also provide a conventional shower water outlet function, thereby improving the practicality and functionality of the output device.

[0065] In this embodiment, the effective mixing and uniform output of cleaning liquid and water are achieved through the structure of the first flow channel and the second flow channel and the position design of the first water port 12 and the first liquid port 13. The cavity 10 is a component for storing cleaning liquid. The designed liquid injection port 11 is convenient for the injection of cleaning liquid. The water flows into the cavity 10 through the first water port 12 from the water inlet 20 to mix with the cleaning liquid and flows out from the first liquid port 13. The different apertures of the first water port 12 and the first liquid port 13 help to adjust the flow ratio of water and the mixed liquid, thereby controlling the mixing ratio. The first-level flow channel 21 introduces water through the first water inlet 23. The second water port 24 is staggered with the first water inlet 23 along the water flow direction to ensure the introduction of water flow, and the water flow is attenuated by the staggered structure, which helps to enhance the effect of the water flow and the mixed liquid coming out of the first liquid port 13. Specifically, the second-level flow channel 22 is connected to the first liquid port 13, so that the mixed liquid can enter the second-level flow channel 22 and mix with the attenuated water flow again. Finally, the effectively mixed cleaning mixture is uniformly output through the liquid outlet 32. When the cleaning liquid is completely used up, the water flowing into the cavity 10 is clean water, so the automatic cleaning function of the cavity 10 can be realized, eliminating the inconvenient cleaning experience caused by the residual cleaning liquid.

[0066] Embodiment 1

[0067] A shower head, comprising a brush assembly 110 and the above-mentioned cleaning liquid output device, such as Figure 5 As shown, it is detachably connected to the body 100, and the brush assembly 110 matches the water outlet 33 and the liquid outlet 32. Specifically, as Figure 6 As shown, the brush assembly 110 and the cleaning liquid output device are detachably connected by the magnetic attraction of magnetic materials, and one of the brush assembly 110 and the body 100 is provided with an iron sheet 41, and the other is provided with a magnet 42. In this embodiment, the brush assembly 110 is provided with an iron sheet toward the body 100, and the body 100 is provided with a magnet 42 at a position corresponding to the iron sheet toward the brush assembly 110. The water outlet of the brush assembly 110 is connected to the water outlet 33 of the body, and the brush assembly 110 is provided with a clearance space to allow the liquid outlet 32 ​​to output the cleaning liquid.

[0068] This embodiment is suitable for pet showers. The current pet bathing process is relatively cumbersome and time-consuming, and usually includes the following steps: first, use a large amount of water to wet the pet's entire body; then, press the pet bath bottle to make it foam, and evenly apply the foam to the pet's entire body; then, use a grooming brush to carefully scrub the pet; finally, use a large area of ​​water again to thoroughly rinse the pet. In this process, the user usually needs to operate with both hands, holding the shower head in one hand and applying shower gel or operating the grooming brush in the other hand. However, some pets may not be able to cooperate with bathing for a long time. At this time, it is often difficult for users to free up one hand to fix the pet, making the bathing process difficult. In addition, when applying and washing pet bath gel, users usually need to use a shell brush to clean the pet's bottom fur, which further increases the complexity of the operation. During the entire bathing process, users also need to frequently turn on and off the shower, pick up and put away the pet shell brush, shower gel and conditioner, which makes the entire bathing process more cumbersome. This embodiment solves the above problems well. At the same time, for different types of pets, it is necessary to frequently replace the brush head.
