As shown in fig. 1 to 3 and 10, a spray device 100 according to an embodiment of the first aspect of the present invention includes: a shower head 1.

A containing cavity is defined in the spray header 1, the spray header 1 is provided with a water inlet 1611 and a water outlet, a gas dissolving cavity 14 and a water inlet channel 16 are arranged in the containing cavity, the water inlet channel 16 can be separated from the gas dissolving cavity 14, the water inlet channel 16 is provided with a water inlet 1611 and an outlet 1621, the gas dissolving cavity 14 is positioned between the outlet 1621 and the water outlet, the outlet 1621 is communicated with the water inlet channel 16 and the gas dissolving cavity 14, and the water outlet is communicated with the gas dissolving cavity 14. Water can enter the water inlet channel 16 from the water inlet 1611, pass through the water inlet channel 16, flow into the gas dissolving cavity 14 through the outlet 1621, and finally be ejected from the water outlet.

Wherein the flow area of the outlet 1621 is smaller than the flow area of the water inlet 1611. Water can be introduced into the dissolved air cavity 14 through the arranged water inlet channel 16, the flow area of the outlet 1621 is smaller than that of the water inlet 1611, the pressure of water flow which is sprayed out of the outlet 1621 of the water inlet channel 16 into the dissolved air cavity 14 through the water inlet channel 16 can be larger, the water pressure of the water flow which flows into the dissolved air cavity 14 is increased, the high-pressure water flow which is sprayed out of the outlet 1621 of the water inlet channel 16 can be more dispersed in the dissolved air cavity 14, the gas dissolving amount of the water flow in the dissolved air cavity 14 is increased, and micro-bubble water can be formed after the water flow in which a large amount of gas is dissolved is sprayed out of the water outlet, so that the dissolved micro-bubble water can be used for cleaning bodies, articles (such as clothes, tableware, fruits, vegetables and fruits) and the like.

The micro-bubble water can realize mechanical washing, and when a large amount of micro-bubble water is contacted with the body or the surface of an article, bubbles collapse to generate huge energy to take away stains; the micro-bubble water can also realize chemical washing and decontamination, and when a large amount of micro-bubble water is contacted with the surface of a body or an article, micro-bubbles generate free radicals to attack stains, so that the stains are decomposed and fall off. Thereby enhancing the cleaning and stain removal ability, for example, the ability to clean the skin can be improved.

For example, when the spraying device 100 is used in a shower system, the spraying device 100 may be connected to a water heater through a pipeline, warm water from the water heater enters the water inlet channel 16 through the water inlet 1611 and is sprayed into the dissolved air cavity 14 from the outlet 1621 through the pipeline connected between the water heater and the spraying device 100, the warm water is excited in the dissolved air cavity 14 to dissolve air in the dissolved air cavity 14, and is finally sprayed out through the water outlet to clean the body, a large amount of micro-bubble water contacts with the surface of the body, the bubbles collapse to generate huge energy to take away the stains, and the micro-bubbles generate radicals to attack the stains, so that the stains are decomposed and fall off, and the spraying function is realized while the cleaning and decontamination capability of the spraying device 100, for example, the capability of cleaning the skin can be improved.

According to the spraying device 100 of the embodiment of the invention, water can be introduced into the dissolved air cavity 14 through the arranged water inlet channel 16, and the water pressure of the water flow sprayed out of the dissolved air cavity 14 can be increased by making the flow area of the outlet 1621 of the water inlet channel 16 smaller than the flow area of the water inlet 1611, so that the high-pressure water flow sprayed out of the outlet 1621 can be more scattered in the dissolved air cavity 14, the gas dissolving amount of the water flow in the dissolved air cavity 14 is increased, and the water flow with a large amount of dissolved gas can form micro-bubble water after being sprayed out of the water outlet, thereby not only realizing the spraying function, but also having stronger cleaning capability and decontamination capability, for example, having stronger capability of cleaning skin.

According to some embodiments of the present invention, referring to fig. 3, 8-10, the water inlet channel 16 includes: a water inlet section 161 and a pressurizing section 162 positioned downstream of the water inlet section 161 (the pressurizing section 162 positioned downstream of the water inlet section 161 means that the pressurizing section 162 is positioned on the downstream side outside the whole water inlet section 161 in the water flow direction), wherein a water inlet 1611 is formed in the water inlet section 161, an outlet 1621 is formed in the pressurizing section 162, and the flow area of the pressurizing section 162 is smaller than or equal to the flow area of the water inlet section 161. The flow area of the pressurizing section 162 refers to the flow area at the position where the cross-sectional area of the pressurizing section 162 is the smallest, and the flow area of the water inlet section 161 refers to the flow area at the position where the cross-sectional area of the water inlet section 161 is the smallest. Through setting up inhalant canal 16 to intake section 161 and pressurization section 162 including the area of flow difference, can reduce the flow loss when the great intake section 161 of area of flow is flowed through to rivers, can pressure boost acceleration rate when the less pressurization section 162 of area of flow is flowed through to rivers, this setting both can reduce the flow loss, and can make the great and speed of rivers pressure of following export 1621 spun higher, high-pressure high-speed rivers impact to the inner wall of dissolved air chamber 14, be of value to increase gaseous dissolved volume, produce more microbubble, strengthen clean soil-removing power.

It should be noted that, the case that the flow area of the pressurizing section 162 is equal to the flow area of the water inlet section 161 means: when the connection of the pressurizing section 162 and the water inlet section 161 has a common cross section, there is a case where the flow areas of the pressurizing section 162 and the water inlet section 161 at the common cross section are the same, and at this time, the flow area of the pressurizing section 162 and the flow area of the water inlet section 161 are both the flow areas at the common cross section, for example, the flow area of the pressurizing section 162 in the extending direction thereof is constant and the flow area of the water inlet section 161 is gradually reduced in the direction from the water inlet section 161 to the pressurizing section 162.

Alternatively, referring to fig. 8-10, the cross-section of the pressing section 162 is elongated, for example, the cross-section of the pressing section 162 may be elongated rectangular. Thus, by providing the cross section of the pressurizing section 162 as a long strip, it is possible to achieve the pressurizing acceleration effect of the water flow and to make the structure of the pressurizing section 162 simple. In which the width direction of the cross section of the pressurizing section 162 may be substantially parallel to the central axis direction of the shower head 1, so that the water flow jetted from the outlet 1621 may collide with the inner wall of the air dissolving chamber 14 in a wider area, which is further beneficial to increase the amount of dissolved air.

Wherein the width of the cross section of the pressing section 162 may be not greater than 2.5mm. Therefore, the width of the pressurizing section 162 is small, the pressurizing section 162 has a better squeezing effect on the water flow, the impact effect of the water flow jetted from the outlet 1621 impacting the inner wall in the gas dissolving cavity 14 is better, and the gas dissolving amount of the water flow in the gas dissolving cavity 14 is more effectively increased.

Wherein, the length of the cross section of the pressing section 162 may range from 8 to 13mm, for example, the length of the cross section of the pressing section 162 may be 10mm. Therefore, the pressurizing effect of the pressurizing section 162 can be ensured, and the water flow sprayed from the outlet 1621 can be wider, and can collide with the inner wall with a larger area in the dissolved air cavity 14, which is further beneficial to increasing the dissolved air amount.

Alternatively, referring to fig. 8-10, the cross-section of the water inlet section 161 is circular. Therefore, the flow loss of the water flow can be further reduced in the process of flowing through the water inlet section 161, so that the water flow in the water inlet section 161 is smoother.

Thus, by providing the pressing plate 3 as two parts of the connecting portion 31 and the pressing portion 32, both the connection fixation of the pressing plate 3 to the shower head 1 and the formation of the pressing section 162 are facilitated. And, through setting up the first location arch 311 on connecting portion 31 and setting up the second location arch 1114 on the inner wall that holds the chamber, when installing the increased pressure plate 3 in shower head 1, through the cooperation of the first location arch 311 on the increased pressure plate 3 and the second location arch 1114 on the shower head 1, can carry out preliminary installation location to increased pressure plate 3, then connect the increased pressure plate 3 through modes such as welded connection, fastener connection and fix in holding the intracavity.

This arrangement also makes it possible to make the pressure and speed of the water flow ejected from the outlet 1621 greater, and makes the structure of the water inlet passage 16 simple. The outlet 1621 may be a hole formed on the water outlet plate, and the outlet 1621 may also include a plurality of water outlet holes formed on the water outlet plate.

According to some embodiments of the present invention, referring to fig. 3 and 12, the shower apparatus 100 includes a cavitation member 2 for generating micro bubbles, the cavitation member 2 is disposed in the containing chamber and located between the water inlet 1611 and the water outlet, a gas dissolving chamber 14 communicated with the water inlet 1611 is defined between the cavitation member 2 and the shower head 1, the gas dissolving chamber 14 is located on a side of the cavitation member 2 adjacent to the water inlet 1611, and a cavitation channel 221 communicating the gas dissolving chamber 14 and the water outlet is formed on the cavitation member 2.

Through the cavitation piece 2 that is used for producing the microbubble that holds the intracavity setting at shower head 1, rivers not only can realize the function that sprays through the micro-nano bubble water that cavitation piece 2 produced, have stronger clean ability and dirt-removing power simultaneously. The micro-nano bubble water can realize mechanical washing, and when a large amount of micro-nano bubble water is in contact with the surface of a body or an article, bubbles collapse to generate huge energy to take away stains; the micro-nano bubble water can also realize chemical washing and decontamination, and when a large amount of micro-nano bubble water is contacted with the surface of a body or an article, the micro-nano bubbles generate free radicals to attack stains, so that the stains are decomposed and fall off.

Alternatively, referring to fig. 2 to 4 and 16 to 18, the showerhead 1 may include: the spray head comprises a spray head body 11 and a spray plate 12, wherein the spray plate 12 is arranged at the open end of the spray head body 11, a water inlet 1611 is formed on the spray head body 11, a water outlet comprises a plurality of spray holes 1211 formed on the spray plate 12, a water outlet cavity 15 is defined between the cavitation member 2 and the spray plate 12, and a cavitation channel 221 is communicated with a dissolved air cavity 14 and the water outlet cavity 15.

For example, when the spraying device 100 is used in a shower system, the spraying device 100 may be connected to a water heater through a pipeline, warm water of the water heater enters the water inlet channel 16 through the water inlet 1611 and is sprayed out from the outlet 1621 into the dissolved air cavity 14 of the shower head 1 through the pipeline connected between the water heater and the spraying device 100, air in the dissolved air cavity 14 is excited to dissolve air in the dissolved air cavity 14, hundreds of millions of micro-nano bubble water may be formed through the cavitation channel 221 of the cavitation member 2 under high pressure, and finally the micro-nano bubble water is sprayed out through the water outlet to clean the body, and a large amount of micro-nano bubble water contacts with the surface of the body, so that the bubbles collapse, generate huge micro-nano energy to take away the stains, and the bubbles generate free radicals to attack the stains, so that the stains are decomposed and fall off, thereby realizing the spraying function, and improving the cleaning and decontamination capabilities of the spraying device 100, for example, improving the skin cleaning capability.

In some alternative embodiments of the invention, referring to fig. 3, 12-15, the flow area of the cavitation member 2 is smaller than the flow area of the outlet 1621. When there is one cavitation passage 221, the flow area of the cavitation member 2 is the flow area of the cavitation passage 221; when the cavitation channel 221 is plural, the flow area of the cavitation member 2 is the sum of the flow areas of all the cavitation channels 221, wherein the flow area of the cavitation channel 221 refers to the flow area at the position where the cross-sectional area of the cavitation channel 221 is smallest.

Wherein the pressure in the air dissolving chamber 14 may be less than the pressure of the tap water.

According to some embodiments of the invention, referring to fig. 3, the cavitation member 2 is adjacent to the water outlet. From this, can be so that inject the great dissolved air chamber 14 of volume between cavitation spare 2 and the shower head 1, thereby make dissolved air chamber 14 can hold more air, and make the distance between cavitation spare 2 and the water inlet 1611 great, rivers that get into in dissolved air chamber 14 through water inlet 1611 can fully mix with the air like this, make more air dissolve in rivers, the rivers that dissolve and have a large amount of air are through the cavitation passageway 221 of cavitation spare 2, can form the volume littleer, the microbubble of the greater quantity, thereby can further improve cleanness, dirt-removing power.

According to some embodiments of the present invention, referring to fig. 12-15, the cavitation channel 221 is formed as a venturi channel, and in the process that the water flow with a large amount of air flowing through the cavitation channel 221, because the flow area of the cavitation channel 221 decreases first and then increases, a great pressure difference is formed at two ends of the cavitation channel 221, the pressure at the cavitation inlet 22111 of the cavitation channel 221 is large, and the pressure at the cavitation outlet 22131 of the cavitation channel 221 is small, which is equivalent to squeezing the water flow with a large cross section into the cavitation channel 221 with a small cross section, the water flow velocity entering the cavitation channel 221 under high pressure will rise rapidly, and in each cavitation channel 221, because the flow area of the cavitation channel 221 decreases first and then increases, the flow velocity and pressure of the water flow change accordingly, the air solubility in the water will decrease, and thus the air will be separated out in the form of micro bubbles, and a large amount of nano-scale micro bubble water can be formed. Therefore, by setting the cavitation channel 221 as a venturi channel, the cavitation effect of the cavitation channel 221 can be further improved, and microbubbles with smaller volume and larger number can be formed, so that the cleaning and decontamination capabilities can be further improved.

For example, in the example of fig. 15, the cavitation channel 221 is a venturi channel, the cavitation channel 221 comprises a tapered section 2211, a throat section 2212 and a diverging section 2213 connected in sequence, the tapered section 2211 has a cavitation inlet 22111, the diverging section 2213 has a cavitation outlet 22131, the flow area of the tapered section 2211 gradually decreases in the direction from the cavitation inlet 22111 to the cavitation outlet 22131, and the flow area of the diverging section 2213 gradually increases in the direction from the cavitation inlet 22111 to the cavitation outlet 22131, wherein the flow area of the throat section 2212 is the smallest. Wherein, the diameter D1 of the cavitation inlet 22111 can be 1.5-2.5mm, the diameter D2 of the throat section 2212 can be 0.5-1.2mm, and the diameter D3 of the cavitation inlet 22111 can be 1.2-2.0mm, so that the cavitation piece 2 can not only produce micro-bubble water with richer micro-bubble content, but also the water flow velocity in the cavitation piece 2 is more moderate, and the blocking risk of the cavitation channel 221 can be reduced.
