Specific embodiments

[0018] The following embodiments illustrate the present utility model, but the present utility model is not limited to these embodiments. Modifications to the specific embodiments of the present utility model or equivalent replacement of some technical features without departing from the scope of the present utility model should be included within the scope of the technical solution of the present utility model. Example 1

[0019] With reference to the Fig. 1 to 5, this embodiment provides a small molecule cluster water generator comprising a housing assembly 1 and a magnetic element 2, wherein a water outlet channel 111 and a plurality of water inlet channels 121 are provided within the housing assembly 1, wherein the water outlet channel 111 is arranged vertically in the center of the housing assembly 1, the plurality of water inlet channels 121 are arranged circumferentially spaced from each other around the water outlet channel 111, and the plurality of water inlet channels 121 are arranged vertically, the upper end of each water inlet channel 121 is connected to the upper end of the water outlet channel 111, and together they form a curved water flow channel, so that the diverted water flowing out from the various water inlet channels 121 can converge in the water outlet channel 111, which is conducive to extending the flow time of the water flow in the magnetic field.A plurality of water inlets 122 are arranged at a circumferential distance from one another at the lower end of the outer side wall of the housing assembly 1. Of course, the plurality of water inlets 122 can also be arranged at a circumferential distance from one another at the bottom of the housing assembly 1, wherein the plurality of water inlets 122 are assigned one-to-one to the plurality of water inlet channels 121 and are connected to one another. A water outlet 112 is provided on the bottom of the housing assembly 1 and is connected to the water outlet channel 111.

[0020] On the outer side wall of the housing assembly 1, a plurality of mounting grooves 123 are provided, and the plurality of mounting grooves 123 are arranged offset from the water inlet channels 121, so that the mounting grooves 123 are formed between adjacent water inlet channels 121, wherein a magnetic element 2 is provided in the mounting groove 123, and in this embodiment, the clockwise opposite ends of the magnetic element 2 are the south pole and the north pole (see Fig. 5), whereby the generator not only generates a magnetic field on the left and right sides of the water inlet channel 121, but also generates a magnetic field around the water outlet channel 111. Therefore, when the tap water flows out of the water inlet 122 of the generator and flows through the water inlet channel 121 and the water outlet channel 111 in succession, it first interrupts the magnetic field between adjacent magnetic elements 2 and then interrupts the magnetic field formed around the water outlet channel 111, that is, the tap water interrupts the two magnetic fields vertically, so that the hydrogen bonds of the tap water in the magnetic field are destroyed, and the tap water with large molecule clusters forms water with small molecule clusters of 6 to 8 water molecules, thereby producing a certain amount of water with small molecule clusters and finally flowing out of the water outlet 112 to the water consumption end.It can be seen that a certain amount of small molecule cluster water can be stably generated when the tap water flows through the generator, whereby the small molecule cluster water is able to utilize its own characteristics of low viscosity, rapid diffusion and many free radicals to completely remove the dense oil layer on the skin surface without damaging the skin.

[0021] With reference to the Fig. 2 and Fig. 3, in this embodiment, a plurality of water passage holes 113 are arranged at the upper end of the peripheral wall of the water outlet channel 111, spaced circumferentially apart. The number of water passage holes 113 is preferably 10 to 30, and the circumferential width of each water passage hole 113 is preferably 1 to 5 mm. The upper end of the water outlet channel 111 is connected to the upper end of the water inlet channel 121 through the water passage holes 113. In other embodiments, a gap for water flow is formed between the upper surface of the water outlet channel 111 and the upper inner surface of the housing assembly 1, and in this case, the gap replaces the plurality of water passage holes 113.

[0022] With reference to the Fig. 1 to 4, furthermore, all the mounting grooves 123 are evenly arranged in the circumferential direction on the outer side wall of the housing assembly 1, and the mounting grooves 123 and the magnetic element 2 are both arranged vertically in a strip-like structure, and the horizontal cross-sectional line shape of the mounting groove 123 and the horizontal cross-sectional line shape of the magnetic element 2 are both trapezoidal or triangular, with a larger radial outer end and a smaller radial inner end, thereby ensuring that the generator has a longer magnetic circuit and the flow time of the water in the magnetic field is prolonged, and at the same time, the strip structure is easy to install, so that the installation efficiency is greatly improved.In this embodiment, the horizontal cross-sectional line shape of the mounting groove 123 and the horizontal cross-sectional line shape of the magnetic member 2 are both trapezoidal, of course, they may also be triangular, so that it can be ensured that the magnetic inductance lines are relatively concentrated and the magnetic field can be utilized to the maximum, thereby improving the generation rate of the water with small molecule clusters.

[0023] The radially outer end of the mounting groove 123 protrudes from the outer side wall of the housing assembly 1; of course, the radially outer end of the mounting groove 123 may also be flush with the outer side wall of the housing assembly 1, and the radially inner end of the mounting groove 123 abuts against the outer surface of the water outlet channel 111 or forms a gap with it. When the radially inner end of the mounting groove 123 abuts against the outer surface of the water outlet channel 111, adjacent water inlet channels 121 are separated by the mounting groove 123, so that the adjacent water inlet channels 121 are independent of each other and do not interfere with each other; when the radially inner end of the mounting groove 123 and the outer surface of the water outlet channel 111 form a gap, the adjacent water inlet channels 121 can be connected to each other through the gap.

[0024] With reference to the Fig. 2 and Fig. 8, a guide surface 21 is provided at the top or bottom end of the magnetic element 2, so that it can be ensured that the magnetic element 2 is not installed upside down, which is conducive to improving assembly efficiency and thereby guaranteeing that a stable and reliable closed magnetic field can be formed. In this embodiment, the magnetic element 2 is preferably a magnet, wherein the top surface of the magnet is an upper plane and the bottom surface of the magnet is a lower plane, and a guide surface 21 is provided at the bottom end of the magnet, wherein the guide surface consists of an inclined surface arranged obliquely in the vertical direction.

[0025] With reference to the Fig. 1 to 3, a downwardly extending handle portion 114 is provided on the underside of the housing assembly 1 to enable rapid assembly of the generator; and / or a plurality of upwardly extending and circumferentially spaced positioning portions 124 are provided on the top side of the housing assembly 1 to enable rapid positioning of the generator assembly.

[0026] With reference to the Fig. 1 to 7, the housing assembly 1 comprises an inner shell 11 and an outer shell 12, wherein the inner shell 11 is provided with a vertically arranged water outlet channel 111 and a water outlet 112 is arranged on the underside of the inner shell 11, and a plurality of water passage holes 113 are arranged at a circumferential distance at the upper end of the inner shell 11, wherein the plurality of water passage holes 113 are each connected to the upper end of the water outlet channel 111. The outer shell 12 has a cylindrical structure provided from top to bottom outside the inner shell 11 and is detachably connected to the inner shell 11, wherein a plurality of circumferentially spaced water inlet channels 121 are formed between the outer shell 12 and the outer side wall of the inner shell 11, wherein the upper ends of the plurality of water inlet channels 121 are each connected to the corresponding water passage holes 113.A plurality of water inlets 122 are provided at the lower end of the outer side wall of the outer shell 12, the plurality of water inlets 122 being assigned one-to-one to the plurality of water inlet channels and connected to each other, and a plurality of mounting grooves 123 are provided on the outer shell 12, the plurality of mounting grooves 123 being arranged offset from the water inlet channels 121, see . Fig. 4.

[0027] It is particularly noted that in other embodiments, the plurality of water passage holes 113 at the upper end of the inner shell 11 may be omitted, and in this case, a gap for water flow may be formed between the upper surface of the inner shell 11 and the upper inner surface of the outer shell 12.

[0028] Furthermore, the inner shell 11 has an inverted "T" shape structure including a vertical water passage portion and a transverse flange portion fixedly connected to the bottom of the vertical water passage portion, wherein a water outlet channel 111 is formed in the vertical water passage portion, and a grille forming a water outlet 112 is provided at a position of the transverse flange portion corresponding to the water outlet channel 111. The grille is superior to a water-permeable structure with small holes and can prevent foreign matter in the water from clogging and affecting the water flow rate, thereby further improving the safety of use.In addition, a downwardly extending grip portion 114 is integrally formed on the underside of the transverse flange portion, and a plurality of upwardly extending and circumferentially equally spaced snap portions 115 are integrally formed on the outer periphery of the upper surface of the transverse flange portion, wherein the plurality of snap portions 115 are assigned one-to-one to the plurality of water inlets 122 on the outer shell 12, and each snap portion 115 is matingly engaged with an edge of the corresponding water inlet 122.Therefore, by the cooperation of the plurality of snap portions 115 on the inner shell 11 and the plurality of water inlets 122 on the outer shell 12, the inner shell 11 can be stably and reliably detachably installed in the outer shell 12, which enables easy replacement, overcomes the disadvantage of the spiral structure which is prone to blockage, and completely improves the utilization rate of the water inlet 122, so that the water inlet can be used on multiple sides.

[0029] Furthermore, the outer shell 12 has a cylindrical structure, and a plurality of upwardly extending and circumferentially spaced positioning portions 124 are integrally formed on the outer surface of the upper side of the outer shell 12. An annular projection 125 extending downwardly is integrally formed on the inner surface of the upper side of the outer shell 12, with an annular recess 126 formed between the annular projection 125 and the inner side wall of the outer shell 12, and the upper end of the inner shell 11 is inserted into the annular recess 126 so that the annular projection 125 and the outer side wall of the outer shell 12 cooperate to define the inner and outer ends of the inner shell 11. Example 2

[0030] With reference to the Fig. 1 to 6, this embodiment differs from Embodiment 1 in that it further comprises at least one of a first sealing element 3, a second sealing element 4 and a filter cartridge (not shown in the figures).The upper end or the lower end of the mounting groove 123 is open and forms an opening, wherein in this embodiment, the lower end of the mounting groove 123 is closed and the upper end is open and forms an opening, wherein the first sealing member 3 is arranged in the opening and is sealingly connected to the outer shell 12 of the housing assembly 1, and the first sealing member 3 may be made of epoxy resin or other sealing materials, so that the sealing by the first sealing member 3 can not only prevent the magnetic member 2 from falling out of the mounting groove 123, but also prevent the magnet in the mounting groove 123 from rusting during the service life, thereby improving the service life of the generator.

[0031] An annular slot 127 is provided at the lower end of the outer side wall of the housing assembly 1, and the second sealing element 4 is inserted into the annular slot 127 to ensure installation sealing after the generator is installed on the water heater. The filter cartridge is detachably installed in the water outlet channel 111 and is designed for sterilization, limescale prevention, adsorption, and other treatments of the water flowing through the water outlet channel 111. Example 3

[0032] With reference to Fig.9, this embodiment illustrates a water heater comprising a water heater body 5 and a small molecule cluster water generator as described in Embodiment 1 or 2, wherein the water heater body 5 is provided with a water inlet pipe 511, a water outlet pipe 512, and a water outlet port 513, wherein a water flow sensor 52 and a water pump 53 are provided at the water inlet pipe 511.A small molecule cluster water generator is provided between the water outlet pipe 512 and the water outlet port 513, wherein the water inlet pipe 511 is connected to a plurality of water inlets 122 of the small molecule cluster water generator via the water outlet pipe 512, and the water outlet port 513 is connected to the water outlet 112 of the small molecule cluster water generator. Thus, tap water enters through the water inlet pipe 511, flows through the water flow sensor 52 and the water pump 53, and then flows into the water heater body 1 for heat exchange. The heated water enters the small molecule cluster water generator to generate a certain amount of small molecule cluster water, and the small molecule cluster water continuously flows to the water consumption end (e.g., the shower head).It can be seen that the water heater can provide a higher content of water with small molecule clusters, which can not only cleanly and thoroughly remove the oil film layer on the skin surface, but also does not damage the skin.

[0033] Furthermore, a distribution box 6 is provided between the water outlet pipe 512 and the water outlet port 513, the distribution box 6 being provided with an installation cavity, a water inlet interface, and a bottom opening, the water inlet interface being connected to the water inlet pipe via the water outlet pipe 512.
