In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0030] The present invention provides a disinfectant water preparation device. Figure 1 and Figure 2 The disinfectant water preparation device includes a liquid storage container 101, which is used to store raw materials 103; the disinfectant water preparation device also includes a base 106, a disinfection component 202, an infusion tube 105 and a spraying mechanism 115, which are used to convert the raw materials 103 in the liquid storage container 101 into disinfectant water and spray it out.

[0031] Disinfection piece 202 contains photocatalyst material, for example more commonly used nano titanium dioxide. After photocatalyst material is irradiated by specific light (for example, ultraviolet irradiation can be utilized for titanium dioxide), the photocatalyst material in disinfection piece 202 can be used as catalyst, water flows through the photocatalyst material and can generate hydroxyl radicals and other substances with strong oxidizing properties, these strong oxidizing substances can decompose multiple organic compounds and inorganic substances with unstable chemical bonds, and can destroy the cell membrane of bacteria and the protein carrier of viruses. The working principle of photocatalyst belongs to known technology, and will not be introduced in detail herein. The strong oxidizing substances produced after water flows through disinfection piece 202 can be mixed in water, thereby water is converted into "disinfectant water" with disinfection and sterilization function.

[0032] Reference Figure 1 and Figure 2, the base 106 is connected to the liquid storage container 101 through the infusion tube 105, the base 106 has a liquid inlet 207, a liquid outlet 208 and a main channel 203, and the liquid storage container 101 has a storage chamber 104 for storing raw materials 103, and the storage chamber 104 is communicated with the main channel 203 through the tube cavity of the infusion tube 105. The liquid spraying mechanism 115 is installed in the base 106, and the liquid spraying mechanism 115 is used to drive the raw materials 103 in the liquid storage container 101 to flow through the tube cavity of the infusion tube 105, the liquid inlet 207, the main channel 203 and the liquid outlet 208 in sequence. The disinfection part 202 is arranged on the wall surface of the main channel 203, and the raw materials 103 can contact with the disinfection part 202 when flowing in the main channel 203. The disinfection part 202 can specifically be a photocatalyst material coating arranged on the wall surface of the main channel 203. The mass ratio of anatase nano-titanium dioxide to rutile nano-titanium dioxide in the disinfection element 202 can be set between 3:1 and 4:1. The particle sizes of the two nano-titanium dioxides can be set between 20-100 nm. When the raw material 103 flows from the liquid storage container 101 to the liquid outlet 208, it will flow through the disinfection element 202 and be converted into disinfectant water.

[0033] First embodiment:

[0034] Based on the above structure, the disinfectant water preparation device can be configured to excite the disinfection element 202 through ambient light (such as sunlight). Specifically, at least a portion of the base 106 is transparent, allowing ambient light to irradiate the disinfection element 202 on the wall of the main channel 203, thereby making the disinfection element 202 work. This configuration does not require a light source for exciting the disinfection element 202, and the device structure is simpler and the cost is lower.

[0035] Second embodiment:

[0036] This embodiment is similar to the first embodiment, the main difference being that the disinfectant water preparation device further comprises an excitation lamp 201, and the light of the excitation lamp 201 can irradiate the disinfection part 202 on the wall of the main channel 203. That is, the disinfectant water preparation device in this embodiment excites the disinfection part 202 by the light emitted by its own lamp. The excitation lamp 201 can be specifically set as an ultraviolet lamp, and the excitation lamp 201 emits medium and long-wave ultraviolet rays with a wavelength between 280-400nm. This setting has fewer restrictions on the use environment of the device, and the device has higher flexibility in use.

[0037] It should be noted that, in order for the light of the excitation lamp 201 to be able to irradiate the disinfection component 202, the light-emitting side of the excitation lamp 201 needs to face the disinfection component 202, and a portion of the base 106 also needs to be set to be transparent so that the light can enter the main channel 203. However, the transparent portion of the base 106 of the second embodiment is slightly different from the transparent portion of the base 106 of the first embodiment. In the first embodiment, in order to allow ambient light to enter, a portion of the outer surface of the base 106 must be transparent; while the disinfectant water preparation device of the second embodiment does not need to rely on ambient light, so in the second embodiment, the outer surface of the base 106 can be opaque. Of course, in both embodiments, a portion of the wall surface of the main channel 203 also needs to be transparent.

[0038] Third embodiment:

[0039] This embodiment is equivalent to a combination of the first embodiment and the second embodiment. In this embodiment, the disinfectant water preparation device can excite the disinfection component 202 by ambient light or by the light of the excitation lamp 201. In this embodiment, the disinfectant water preparation device includes an excitation lamp 201, and the light of the excitation lamp 201 can illuminate the disinfection component 202 on the wall of the main channel 203; and a part of the base 106 is transparent so that the ambient light can illuminate the disinfection component 202. When the ambient light is sufficient, the excitation lamp 201 does not need to be turned on, and there is no need to power the excitation lamp 201; when the ambient light is insufficient, the excitation lamp 201 is turned on. The disinfectant water preparation device of this embodiment has high flexibility in use and low energy consumption.

[0040] Accordingly, refer to Figure 6 or Figure 7 , the position of the excitation lamp 201 should be set at a position that does not block the ambient light penetrating into the base 106. In addition, it should be noted that, in combination with Figure 6 and Figure 7 The disinfection element 202 does not necessarily need to surround the main channel 203 along the circumference of the main channel 203, but may only surround a portion of it (half a circle, a quarter of a circle, etc.). The light from the excitation lamp 201 or the ambient light can directly irradiate the side of the disinfection element 202 that is used to contact the raw material 103, thereby increasing the reaction rate.

[0041] The disinfectant water preparation device of the present invention has a raw material 103 stored in its storage container at ordinary times, which is water (not necessarily pure water, and may contain some impurities, and the raw material 103 contains liquid water). The raw material 103 is ejected only when the device needs to be used, and the raw material 103 is converted into disinfectant water during the ejection process of the raw material 103; when the water flows in the main channel 203, it contacts the photocatalyst material, and the generated strong oxidizing substance is mixed with the water and ejected together, so that the ejected water has the effect of disinfection and sterilization. The disinfectant water preparation device of the present invention stores water that is not easy to deteriorate when idle, and converts the water into disinfectant water and ejects it when disinfection is needed. The disinfectant water preparation device does not need to store a large amount of disinfectant water for a long time, and avoids the disinfectant water from being deteriorated due to long-term placement.

[0042] In addition, the raw material 103 is water, and the raw material 103 does not contain any toxic substances. Even if the raw material 103 in the liquid storage container 101 leaks accidentally, it will not cause harm to the human body or objects.

[0043] The following will further describe other structures of the disinfectant water preparation device. In the following, unless otherwise specified, the structural arrangement mentioned below can be combined with any one of the above three embodiments. Since there are multiple embodiments that can be formed after the combination, the serial number of the embodiment will no longer be clearly identified below.

[0044] Reference Figure 1 and Figure 2In some embodiments, the disinfectant water preparation device is similar to a spray bottle as a whole, which is convenient for handheld use. The base 106 has a compression chamber 204, which is connected to the main channel 203, and the connection between the main channel 203 and the compression chamber 204 is located between the liquid inlet 207 and the liquid outlet 208. The liquid spraying mechanism 115 includes a pressure rod 112, a piston 110, a first elastic member 109, a first blocking member 108 and a second elastic member 113. The base 106 is installed at the top of the liquid storage container 101 to cover the top of the storage chamber 104 to prevent external gas from entering. The pressure rod 112 is installed on the base 106, and the pressure rod 112 is for the user to press. The piston 110 is slidably arranged in the compression chamber 204, and one end of the first elastic member 109 abuts against the piston 110. The first elastic member 109 is arranged in the compression chamber 204, and one end of the first elastic member 109 abuts against the base 106. After the user pushes the pressure rod 112, the pressure rod 112 will move relative to the base 106 and push the piston 110. The piston 110 moves in the direction of compressing the first elastic member 109. Accordingly, the piston 110 pushes the fluid into the main channel 203. The first blocking member 108 is arranged at the liquid inlet 207, and the second blocking member 111 is arranged at the liquid outlet 208. Both the first blocking member 108 and the second blocking member 111 play a one-way blocking role. Among them, the first blocking member 108 allows the fluid to enter the main channel 203 from the lumen of the infusion tube 105, and can prevent the fluid from flowing from the main channel 203 into the lumen of the infusion tube 105; the second blocking member 111 allows the fluid to flow out from the liquid outlet 208 to the external environment, and can prevent air from entering the main channel 203 from the external environment. The fluid mentioned here when describing the functions of the first blocking member 108 and the second blocking member 111 may refer to air, raw materials or disinfectant water.

[0045] Combine the following Figures 2 to 5 Introduce the principle of the spray mechanism; for the convenience of demonstration, Figures 2 to 5 The shape of the base 106 is simplified, and the first elastic member 109 is omitted. Figure 2 is the initial state, the spray mechanism can be changed into Figure 3 , Figure 4 and Figure 5 status, and ultimately by Figure 5 Status return Figure 2 The state of the liquid injection mechanism is as follows Figures 2 to 5 In addition, Figures 2 to 5 In the figure, the dotted arrows indicate the flow direction of the fluid.

[0046] Reference Figure 2 and Figure 3The user presses the pressure rod 112 to make the piston 110 push the air or raw material 103 in the compression chamber 204 into the main channel 203. Due to the blocking effect of the first blocking member 108, this part of the air or raw material 103 will flow out from the liquid outlet 208.

[0047] Reference Figure 2 and Figure 5 When the user releases the pressure rod 112, the piston 110 is reset under the action of the first elastic member 109. Due to the blocking of the second blocking member 111 and the sealing of the piston 110, the air in the external environment cannot enter the main channel 203, the air pressure in the main channel 203 is reduced, and the raw material 103 in the storage chamber 104 is sucked into the main channel 203 and finally enters the compression chamber 204.

[0048] The user continuously presses and releases the pressure rod 112 to draw the raw material 103 in the storage chamber 104 into the main channel 203 and spray it out, and the raw material 103 contacts the disinfection element 202 in the main channel 203 to generate strong oxidizing substances. The right end of the base 106 also has a plurality of small spray holes 114 so that the disinfectant water can be sprayed out in a mist form.

[0049] Reference Figure 2 In some embodiments, the base 106 also includes an air inlet channel 205, both ends of which are connected to the storage chamber 104 and the compression chamber 204 respectively; the air inlet channel 205 is connected to the compression chamber 204, thereby forming an air inlet 206 on the side wall of the compression chamber 204.

[0050] Reference Figures 2 to 4 In the initial stage of the movement of the piston 110, a part of the air or raw material 103 (this part is smaller) in the compression chamber 204 will enter the storage chamber 104 from the air inlet 206, and another part of the air or raw material 103 (this part is larger) will enter the main channel 203; then the piston 110 blocks the air inlet 206, and the air or raw material 103 only enters the main channel 203; after the piston 110 passes over the air inlet 206, the air inlet 206 is connected to the external environment, and the air of the external environment enters the air inlet channel 205 through the air inlet 206 and finally enters the storage chamber 104 to stabilize the air pressure in the storage chamber 104. It should also be noted that in the process of repeatedly pressing and releasing the pressure rod 112, based on the size of the air inlet 206 and the relative position between the air inlet 206 and the piston 110, only a small part of the fluid in the compression chamber 204 will flow into the storage chamber 104 from the air inlet channel 205 (and the stage of allowing the fluid in the compression chamber 204 to flow out of the air inlet 206 is short), which will not affect the liquid spraying.

[0051] Reference Figure 2 , Figure 3 and Figure 5The first blocking member 108 blocks the liquid inlet 207 by its own gravity, which can reduce the total number of parts in the device and reduce the assembly process. The liquid spraying mechanism 115 also includes a second elastic member 113, one end of the second elastic member 113 is connected to the second blocking member 111, and the other end of the second elastic member 113 is against the base 106. The second elastic member 113 is in a compressed state, and the second blocking member 111 blocks the liquid outlet 208 by the elastic force of the second elastic member 113, so that the second blocking member 111 can be suitable for the case where the second half of the main channel 203 is horizontally arranged.

[0052] The following is an introduction to the relevant structure for controlling the switch of the excitation lamp 201. This part of the structure is suitable for a disinfection water preparation device provided with the excitation lamp 201.

[0053] Reference Figure 1 and Figure 8 , the disinfectant water preparation device further includes a power supply 102, which is electrically connected to the excitation lamp 201 to form a connection loop 801, and the power supply 102 is used to power the excitation lamp 201. In some embodiments, the disinfectant water preparation device further includes a first switch 116, which is arranged in the connection loop 801 to control the switch of the excitation lamp 201; the first switch 116 is installed between the pressure rod 112 and the piston 110, and the pressure rod 112 and the piston 110 can clamp the first switch 116, so that the connection loop 801 is turned on. The first switch 116 can be set as a contact switch, and the first switch 116 is installed at one end of the piston 110 facing the pressing member, or installed on the side of the pressure rod 112 facing the piston 110. When the user presses the pressure rod 112, the gap between the pressure rod 112 and the piston 110 is reduced until the piston 110 and the pressure rod 112 clamp the first switch 116, and then the first switch 116 turns on the connection loop 801, and the excitation lamp 201 is running.

[0054] Reference Figure 1 The power supply 102 can be installed at the bottom of the liquid storage container 101 to lower the center of gravity of the disinfectant water preparation device and make the device more stable. The cable used to connect the power supply 102 and the excitation lamp 201 can be set in the wire groove of the liquid storage container 101 and the base 106 (the wire groove is not specifically shown)

[0055] Reference Figure 1 and Figure 8In some embodiments, the disinfectant water preparation device further includes a second switch 107, which is mounted on the base 106, and the second switch 107 is arranged in series with the first switch 116 in the connection loop 801. When the second switch 107 is disconnected, even if the first switch 116 is closed, the excitation lamp 201 cannot be operated. If the first switch 116 and the second switch 107 are arranged based on the second embodiment, the second switch 107 is equivalent to the main switch to prevent the excitation lamp 201 from lighting up when not needed due to the accidental touch of the first switch 116. If the first switch 116 and the second switch 107 are arranged based on the third embodiment, the second switch 107 is mainly used to switch the operation mode of the disinfectant water preparation device; when the second switch 107 is disconnected, the disinfectant water preparation device relies on ambient light to operate, and when the second switch 107 is closed, the disinfectant water preparation device can operate under the action of its own excitation lamp 201.

[0056] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
