Description

Technical Field

[0001] The present application relates to the technical field of water purification equipment, and in particular to a desktop water purifier. Background Art

[0002] As people become increasingly concerned about drinking water health, the water tanks of tabletop water purifiers are generally designed to be external and detachable, allowing for easy removal and cleaning. It's well known that when water is left in a tank for too long and exposed to air for extended periods, it can lead to excessive bacterial counts, which can affect people's drinking health. Therefore, sterilizing water stored in tanks for extended periods of time is an urgent issue.

[0003] Currently, a common sterilization method is irradiation with a germicidal lamp, such as a UV germicidal lamp, which uses ultraviolet light to kill a wide range of pathogens. Existing tabletop water purifiers equipped with a germicidal lamp are often mounted on the bottom wall of the water tank. The lamp has a contact, and the water tank base has a contact point connected to a power source at a position corresponding to the contact point. When the water tank is mounted on the base, the contact point makes contact, powering the germicidal lamp. When the water tank is removed from the base, the contact point separates, cutting off the power supply to the germicidal lamp. While this solution effectively sterilizes the water in the water tank using the germicidal lamp, the contact point power supply, due to contact-to-contact power supply, can cause poor contact after long-term use due to oxidation or water immersion, leading to lamp failure. Furthermore, the germicidal lamp's secure installation on the water tank is challenging. If the lamp is not securely mounted, it can easily fall off when the water tank is removed from the base. In addition, the germicidal lamp installed on the water tank can only sterilize the water in the water tank. Its function is relatively simple and its applicability is poor. Utility Model Content

[0017] Due to the adoption of the above technical solution, the technical effects achieved by this application include at least:

[0018] 1. Compared with the existing method of installing the germicidal lamp on the water tank, the desktop water purifier provided in the present application installs the germicidal lamp on the water tank base. The power supply of the germicidal lamp can eliminate the contact and contact power supply method. For example, the power supply and the germicidal lamp can be connected by a wire to improve or solve the problem of poor contact caused by oxidation or water immersion of the contacts. Moreover, the germicidal lamp is not removed and placed on the water tank base with the auxiliary sterilization shading member. It is always placed on the water tank base, which solves the problem of easy falling off. In addition, the auxiliary sterilization light shielding member in this solution is not limited to a single water holding function. It can be designed as a water tank to meet the demand for long-term storage of water sterilization. It can also be designed as other structures, such as a container that can accommodate cups, bottles, and nipples. When the auxiliary sterilization light shielding member cooperates with the water tank base to form a sterilization cavity surrounding the sterilization lamp, the sterilization lamp can sterilize cups, bottles, nipples, etc. placed in the sterilization cavity. Therefore, the sterilization function of the desktop water purifier is expanded, and the usage scenarios are more abundant. In addition, under the shading effect of the auxiliary sterilization light shielding member, the light of the sterilization lamp is effectively prevented from leaking to the outside of the auxiliary sterilization light shielding member.

[0019] 2. As a preferred embodiment of the present invention, the auxiliary sterilization light shielding member is configured as a water tank assembly. The water tank body serves as a water storage container, and the water stored therein can be sterilized by a germicidal lamp. A water barrier separates the sterilization chamber into a space below surrounding the germicidal lamp and an upper water storage chamber, preventing contact between the germicidal lamp and water and improving safety. The light-transmitting element installed in the mounting hole of the water barrier allows light from the germicidal lamp to penetrate into the water storage chamber for sterilization.

[0020] 3. As a preferred embodiment of the present application, the light-transmitting member is provided with a scattered light area protruding toward the inside of the water storage chamber, and the germicidal lamp extends into the concave cavity formed outside the scattered light area, so that the germicidal lamp has a larger irradiation angle and irradiation area toward the water storage chamber, thereby improving the sterilization efficiency of the water in the water storage chamber.

[0021] 4. As a preferred embodiment of the present application, the auxiliary sterilization light shielding member is configured as a light shield with an opening at the bottom, which can be directly inverted on the base of the water tank, and form a sterilization cavity with the base of the water tank that can accommodate other containers or items, so that the sterilization cavity can be used as a sterilization chamber to sterilize other containers or items, such as cups, bottles, nipples, etc. It is only necessary to place the containers or items to be sterilized in a position that can be irradiated by the sterilization lamp in advance, and then install the auxiliary sterilization light shielding member on the base of the water tank and irradiate the containers or items to be sterilized, and then the sterilization lamp can be turned on to achieve the sterilization function.

[0022] 5. As a preferred embodiment of the present application, the contacts of the micro switch protrude from the outside of the water tank base so as to be able to detect whether the auxiliary sterilization shading element is installed on the water tank base. When the contacts detect that the auxiliary sterilization shading element is installed on the water tank base, the sterilization lamp can be powered on for sterilization. When the contacts detect that the auxiliary sterilization shading element is not installed on the water tank base, the sterilization lamp cannot be powered on for sterilization, so as to prevent the sterilization function from being mistakenly turned on due to the absence of the auxiliary sterilization shading element on the water tank base, resulting in leakage of sterilization light.

[0023] 6. As a preferred embodiment of the present application, a lamp hole is provided on the top of the water tank base, and the germicidal lamp is detachably installed in the lamp hole so that the germicidal lamp can be replaced in time when damaged to maintain the normal use of the sterilization function.

[0047] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present application.

[0051] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "examples," "specific examples," or "some examples" means that a specific feature, structure, material, or characteristic described in conjunction with that embodiment or example is included in at least one embodiment or example of the present application. Throughout this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0052] In the embodiments of this application, a tabletop water purifier is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and schematic description and does not constitute a specific limitation of the technical solution provided in this application.

[0053] like Figures 1 to 9 As shown, the present application provides a desktop water purifier, including a body 1, the body 1 is provided with a water tank base 2, the water tank base 2 is equipped with a sterilization lamp 3, and the desktop water purifier also includes an auxiliary sterilization shading member 4 that can be removably installed on the water tank base 2; when the auxiliary sterilization shading member 4 is installed on the water tank base 2, it cooperates with the water tank base 2 to form a sterilization cavity 5 surrounding the sterilization lamp 3.

[0054] Compared with the existing method of installing the germicidal lamp on the water tank, the desktop water purifier provided in the present application installs the germicidal lamp 3 on the water tank base 2. The power supply of the germicidal lamp 3 can eliminate the contact and contact power supply method. For example, the power supply and the germicidal lamp 3 can be connected by a wire to improve or solve the problem of poor contact of the contacts due to oxidation or water immersion. Moreover, the germicidal lamp 3 is not taken out and placed on the water tank base 2 with the auxiliary sterilization shading member 4. It is always placed on the water tank base 2, which solves the problem of easy falling off. In addition, the auxiliary sterilization shading member 4 in this solution is not limited to a single water holding function. It can be designed as a water tank to meet the functional requirements of long-term storage of water sterilization. It can also be designed as other structures, such as a container that can accommodate cups, bottles, and nipples. When the auxiliary sterilization shading member 4 cooperates with the water tank base 2 to form a sterilization cavity 5 surrounding the sterilization lamp 3, the sterilization lamp 3 can sterilize cups, bottles, nipples, etc. placed in the sterilization cavity 5. Therefore, the sterilization function of the desktop water purifier is expanded, and the usage scenarios are more diverse. In addition, under the shading effect of the auxiliary sterilization shading member 4, the light of the sterilization lamp 3 is effectively prevented from leaking to the outside of the auxiliary sterilization shading member 4.

[0055] In a preferred embodiment, the germicidal lamp 3 can be a UV germicidal lamp (ultraviolet germicidal lamp), which meets the requirements of water sterilization and sterilization of most containers or items such as cups, bottles, and pacifiers. Of course, other suitable germicidal lamps can also be selected according to the particularity of the sterilized items.

[0056] As a preferred embodiment, Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the water tank base 2 is equipped with a micro switch 6 for controlling the power-on state of the germicidal lamp 3. The contact 61 of the micro switch 6 protrudes from the outside of the water tank base 2 so as to be able to contact and detect whether the auxiliary sterilization light shielding member 4 is installed on the water tank base 2. It is understood by those skilled in the art that the auxiliary sterilization light shielding member 4 is detected by the contact 61. When the contact 61 detects that the auxiliary sterilization light shielding member 4 is installed on the water tank base 2, the germicidal lamp 3 can be powered on for sterilization. When the contact 61 detects that the auxiliary sterilization light shielding member 4 is not installed on the water tank base 2, the germicidal lamp 3 cannot be powered on for sterilization, so as to prevent the sterilization function from being mistakenly turned on when the auxiliary sterilization light shielding member 4 is not placed on the water tank base 2, resulting in leakage of the germicidal light.

[0057] Further, if Figure 1 、 Figure 2 and Figure 6As shown, a through hole 21 is provided on the side of the water tank base 2, and the micro switch 6 is installed in the water tank base 2. The contact 61 passes through the through hole 21 and protrudes from the outside of the water tank base 2. The inner wall of the water tank base 2 is provided with a positioning clip 22, and the micro switch 6 is stopped in the positioning groove 23 surrounded by the positioning clip 22. During assembly, it is only necessary to align the end of the micro switch 6 with the contact 61 inside the water tank base 2 with the through hole 21 and insert it. The micro switch 6 presses the positioning clip 22 outward, causing the positioning clip 22 to expand and deform and clamp the micro switch 6 in the positioning groove 23 surrounded by it. The micro switch 6 can then be installed in place and positioned, greatly improving the convenience of assembly of the micro switch 6.

[0058] As a preferred embodiment, Figure 1 、 Figure 2 and Figure 6 As shown, the top of the water tank base 2 is provided with a lamp hole 24, and the germicidal lamp 3 is detachably mounted in the lamp hole 24. The germicidal lamp 3 irradiates the sterilization chamber 5 through the top opening of the lamp hole 24. In this solution, the germicidal lamp 3 is detachable, which facilitates timely replacement of the germicidal lamp 3 when damaged, thereby maintaining the normal use of the sterilization function.

[0059] Further, if Figure 2 and Figure 6 As shown, the germicidal lamp 3 is provided with a positioning flange 31, which abuts the bottom surface of the lamp hole 24 and is screwed to the water tank base 2. Multiple second sealing members 8 are provided between the germicidal lamp 3 and the inner wall of the lamp hole 24. Specifically, screw holes 32 can be provided at both ends of the positioning flange 31, and screw posts 25 can be provided on the water tank base 2. Screws are inserted through the screw holes 32 and the screw posts 25 to connect the positioning flange 31 to the water tank base 2. The multiple second sealing members 8 form a multiple seal between the germicidal lamp 3 and the inner wall of the lamp hole 24, effectively preventing any water that may accumulate on the top surface of the water tank base 2 from leaking into the interior of the water tank base 2.

[0060] Regarding the structure of the auxiliary sterilization shading member 4, it can adopt any one of the following embodiments:

[0061] Example 1:

[0062] like Figures 3 to 8As shown, the auxiliary sterilization light shielding member 4 is configured as a water tank assembly, comprising a water tank body 41 and a light-transmitting member 42. The sidewall 411 of the water tank body 41 covers the water tank base 2 to enclose the sterilization chamber 5. The sidewall 411 is provided with a water barrier 412, which isolates a water storage chamber 413 within the sterilization chamber 5. The water barrier 412 is provided with a mounting hole 4121, and the light-transmitting member 42 is mounted in the mounting hole 4121. The germicidal lamp 3 illuminates the water storage chamber 413 from the outside of the water storage chamber 413 through the light-transmitting member 42. In this embodiment, the auxiliary sterilization light shielding member 4 is configured as a water tank assembly, with the water tank body 41 serving as a water storage container. Water stored therein for a long time can be sterilized by the germicidal lamp 3. The water-blocking wall 412 separates the sterilization chamber 5 into a space surrounding the sterilization lamp 3 below and a water storage chamber 413 above, thereby preventing the sterilization lamp 3 from contacting water and improving safety of use. The light-transmitting effect of the light-transmitting component 42 installed in the mounting hole 4121 of the water-blocking wall 412 allows the light from the sterilization lamp 3 to be projected into the water storage chamber 413 to achieve sterilization.

[0063] When the germicidal lamp 3 is configured as a UV germicidal lamp, the light-transmitting member 42 is preferably made of quartz glass. Quartz glass has the advantages of high temperature resistance, extremely small thermal expansion coefficient, and good chemical stability. In addition, the bubbles, stripes, uniformity, and birefringence are comparable to those of general optical glass. Most importantly, quartz glass has a high ultraviolet transmittance, thereby generating extremely high ultraviolet radiation output. Therefore, when used in conjunction with a UV germicidal lamp, it can effectively improve the ultraviolet intensity of the germicidal lamp 3, thereby improving the sterilization effect and efficiency.

[0064] In a preferred embodiment, Figure 5 and Figure 6 As shown, the light-transmitting member 42 is a planar light-transmitting member, for example, a planar quartz glass, which has a simple structure and low cost. Figure 7 and Figure 8 As shown, the light-transmitting member 42 is provided with a scattered light area 421 protruding toward the inside of the water storage chamber 413, and the germicidal lamp 3 extends into the concave cavity formed outside the scattered light area 421, so that the germicidal lamp 3 has a larger illumination angle and illumination area toward the water storage chamber 413, thereby improving the sterilization efficiency of the water in the water storage chamber 413.

[0065] Further, if Figure 2 、 Figure 4 and Figure 6As shown, a first sealing body 7 is provided between the light-transmitting member 42 and the water tank body 41, and the water tank assembly further comprises a snap-fitting member 9, which is snap-fitted to the water tank body 41 and stops the first sealing body 7 and the light-transmitting member 42 in the mounting hole 4121. The first sealing body 7 ensures the sealing performance of the mounting hole 4121 when the light-transmitting member 42 is installed, thereby preventing the water storage chamber 413 from leaking outward through the mounting hole 4121. Preferably, the first sealing body 7 can be wrapped around the edge of the light-transmitting member 42 to help improve the sealing effect. A buckle can be provided on the edge of the snap-fitting member 9, and a slot can be provided in the mounting hole 4121, so that the snap-fitting member 9 is snap-fitted to the water tank body 41 through the buckle and the slot.

[0066] In this embodiment, Figure 3 、 Figure 4 and Figure 6 As shown, the water-blocking wall 412 is provided with a water hole 4122 communicating with the water storage chamber 413. A first one-way valve 10 is provided in the water hole 4122. A water flow channel 20 is provided in the water tank base 2, and a second one-way valve 30 is provided in the water flow channel 20. When the water tank body 41 is mounted on the water tank base 2, the first one-way valve 10 and the second one-way valve 30 push each other to open the water hole 4122 and the water flow channel 20, respectively. When the water tank body 41 is separated from the water tank base 2, the first one-way valve 10 seals the water hole 4122 while the second one-way valve 30 seals the water flow channel 20. With the above design, the water hole 4122 and the water flow channel 20 are opened to allow water to flow in and out of the water storage chamber 413 only when the water tank assembly is mounted on the water tank base 2. When the water tank assembly is removed from the water tank base 2, the water hole 4122 and the water flow channel 20 are both closed to prevent water leakage.

[0067] Example 2:

[0068] like Figure 9 As shown, the auxiliary sterilization light shielding member 4 is configured as a light shield with an opening at the bottom, and the light shield is disposed on the water tank base 2 through the opening. In this solution, the auxiliary sterilization light shielding member 4 can be directly buckled onto the water tank base 2, and together with the water tank base 2, form a sterilization cavity 5 that can accommodate other containers or items, so that the sterilization cavity 5 can be used as a sterilization chamber to sterilize other containers or items, such as cups, bottles, pacifiers, etc., by simply placing the container or item to be sterilized in a position that can be illuminated by the sterilization lamp 3 in advance, then installing the auxiliary sterilization light shielding member 4 on the water tank base 2 and irradiating the container or item to be sterilized, and then turning on the sterilization lamp 3 to achieve the sterilization function.
