Description

Technical Field

[0001] This utility model belongs to the field of drinking water equipment, specifically relating to a tea bar machine. Background Technology

[0002] A tea bar machine is a small household appliance that combines drinking water and tea brewing functions. Its convenient and efficient water heating method is highly favored by consumers. In recent years, with the continuous upgrading of market demand, the functions of tea bar machines have also become increasingly diverse. Tea bar machines on the market typically have a cabinet. The top of the cabinet is used to place the kettle, and the inside of the cabinet is used to place the water bucket. The water pump pipe of the tea bar machine is inserted into the water bucket to draw drinking water from it. Because the drinking water in the bucket takes a relatively long time to be consumed, some tea bar machines are equipped with a sterilizing lamp at the end of the water pump pipe to sterilize the drinking water in the bucket.

[0003] Currently, existing sterilization lamps can only be turned on or off based on user operation, and cannot be turned on or off based on whether there is drinking water in the water tank. Users need to open the cabinet to check whether the drinking water in the tank is empty. That is, when the drinking water in the tank is empty and there is no need for the sterilization lamp to continue sterilizing the drinking water, if the user does not notice and turn off the sterilization lamp in time, the sterilization lamp will remain on, resulting in a waste of electricity. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tea bar machine to solve the problem of wasted power resources caused by the sterilization lamp not being able to turn on and off according to whether there is water in the water tank.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a tea bar machine, including a cabinet, a water storage container disposed within the cabinet, and a water pump pipe extending into the water storage container. The end of the water pump pipe is equipped with a sterilization device for water flow. The sterilization device includes a water source triggering component, a sterilizing lamp, and a connecting shell connected to the water pump pipe. The sterilizing lamp is installed between the connecting shell and the water source triggering component to contact the liquid in the water storage container. When the water source triggering component is triggered by the liquid, the sterilizing lamp turns on to sterilize the liquid in the water storage container. This technical solution has the following technical effects:

[0006] This invention features a sterilization device with a germicidal lamp at the end of a water pipe, and a water source triggering component on the device to detect liquid. This triggering component detects the liquid and activates the germicidal lamp upon detection, sterilizing the liquid in the storage container. Because the germicidal lamp is in direct contact with the liquid, rather than being hidden within the connecting shell or the triggering component, it sterilizes the liquid without needing to penetrate the shell, resulting in superior sterilization and preventing excessive bacterial growth in the water, making it safer to drink. The triggering component can be set to activate upon contact with the liquid in the storage container or to activate when liquid is drawn. Both methods rely on the presence of liquid in the container. Therefore, when the liquid in the container is depleted, the triggering component cannot be activated, and the germicidal lamp remains off. This ensures the germicidal lamp does not operate when the liquid in the container is empty, preventing it from working in an empty container and significantly saving energy.

[0007] In the aforementioned tea bar machine, the water source triggering component includes a water-passing shell and a triggering mechanism. The water-passing shell contains a water-passing channel and a detection channel. The water-passing channel is connected to the water intake pipe, and the triggering mechanism is installed on top of the detection channel and electrically connected to a germicidal lamp. By installing the triggering mechanism on top of the detection channel, the water-passing channel and the detection channel perform different functions. When the water intake pipe draws liquid, the liquid enters the water-passing channel and the detection channel of the water source triggering component. The portion entering the water-passing channel can enter the water intake pipe, while the portion entering the detection channel can trigger the triggering mechanism. The water-passing channel and the detection channel provide a certain degree of separation within the water-passing shell, allowing a large amount of liquid to enter the water intake pipe through the water-passing channel. This prevents excessive pressure on the triggering mechanism caused by a large amount of liquid impacting it, thus avoiding damage to the triggering mechanism due to excessive pressure and extending its service life.

[0008] In the aforementioned tea bar machine, the triggering mechanism includes a power supply module with a micro switch at the bottom and a triggering module located below the micro switch. The power supply module is electrically connected to the sterilizing lamp. The triggering module includes a diaphragm covering the top of the water passage and a push rod mounted on the diaphragm. The diaphragm triggers the micro switch by pushing the push rod upward. When the hydraulic pressure in the detection channel reaches a set value, the diaphragm deforms under pressure, and its center pushes the trigger rod upward. When the trigger rod contacts the micro switch to close it, the power supply circuit is connected, and the power supply module supplies power to the sterilizing lamp to turn it on. By configuring the triggering mechanism with the micro switch, diaphragm, and trigger rod working together, the diaphragm can be deformed by hydraulic pressure, thereby driving the trigger rod to trigger the micro switch. The minimal deformation of the diaphragm can be transmitted to the micro switch through the trigger rod to connect the circuit, resulting in high detection accuracy and greater sensitivity of the triggering mechanism.

[0009] In the aforementioned tea bar machine, the triggering mechanism includes a power supply module with a Hall switch at the bottom and a float with a magnet inside. The power supply module is electrically connected to the sterilizing lamp, and the float is slidably connected in the detection channel below the Hall switch. The float triggers the Hall switch by floating upwards. When there is liquid in the water storage container, the liquid enters the water passage and detection channel of the sterilization device immersed in the liquid. Under the action of buoyancy, the float in the detection channel moves the magnet closer to the Hall switch to trigger it, and the sterilizing lamp turns on to sterilize the liquid in the water storage container. When the liquid in the water storage container is exhausted, there is no liquid in the detection channel, and the float falls under the action of gravity, moving the magnet away from the Hall switch and no longer triggering it. The sterilizing lamp then turns off. By setting the triggering mechanism to a structure in which the Hall switch and the float with a magnet cooperate, the triggering mechanism is simple, reliable, not easily damaged, and has a long service life.

[0010] In the aforementioned tea bar machine, a stop step is provided on the inner wall of the detection channel, located below the float. The stop step limits the float by abutting against the bottom of the float. When there is no liquid in the detection channel, the float falls to the bottom under the action of gravity and stops falling when it abuts against the stop step, preventing the float from freely detaching from the bottom of the detection channel.

[0011] In the aforementioned tea bar machine, the water passage shell includes an outer shell forming a water passage channel and an inner shell forming a detection channel. The inner shell is fixed at the center of the outer shell so that the water passage channel surrounds the detection channel. By arranging the water passage channel around the detection channel, the liquid flowing into the detection channel can be diverted from all sides to the water passage channel, preventing the triggering mechanism inside the detection channel from being subjected to excessive pressure and thus avoiding water ingress or damage.

[0012] In the aforementioned tea bar machine, the bottom of the outer casing has multiple downward-facing recesses that penetrate the casing. The side of the water passage connects to the interior of the water storage container through these recesses. When the water pipe draws liquid, the liquid in the water storage container can enter the water passage not only through the bottom of the water passage but also through the recesses on the side of the water passage, allowing for rapid extraction by the water pipe.

[0013] In the aforementioned tea bar machine, the germicidal lamp includes a ring-shaped light strip and connecting parts located at the upper and lower ends of the light strip. The two connecting parts are threadedly connected to a connecting shell and a water-passing shell, respectively, to fix the light strip between the connecting shell and the water-passing shell. By setting the germicidal lamp as a ring-shaped light strip and fixing it to the connecting shell and the water-passing shell through the two connecting parts, the germicidal lamp is made into a ring shape, which increases the irradiation range of the liquid in the water storage container and irradiates the liquid around the lamp, resulting in a good sterilization effect. Simultaneously, the hollow structure of the light strip provides sufficient space for liquid flow and the installation of the triggering mechanism, reducing the overall size of the sterilization device and allowing it to be inserted into the water storage container through the opening.

[0014] In the aforementioned tea bar machine, the water source triggering component is activated when it comes into contact with the liquid in the water storage container to turn on the sterilizing lamp, so as to sterilize the liquid in the water storage container; or, when the water pipe is pumping water, the water source triggering component is activated by pressure to turn on the sterilizing lamp, so as to sterilize the liquid in the water storage container when it is being pumped out.

[0015] In the aforementioned tea bar machine, the connecting shell is provided with a liquid outlet and a sleeve surrounding the liquid outlet, the sleeve being sealed to the end of the water pump pipe. The sleeve increases the contact area between the water pump pipe and the sterilization device, allowing the sterilization device to be securely mounted to the bottom of the water pump pipe, preventing the sterilization device from detaching freely from the bottom of the water pump pipe.

[0016] The features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0027] This utility model discloses a tea bar machine, including a cabinet, a water storage container housed within the cabinet, and a water pump pipe extending into the water storage container. The end of the water pump pipe is equipped with a sterilization device through which water flows. The sterilization device includes a water source triggering component, a sterilizing lamp, and a connecting shell connected to the water pump pipe. The sterilizing lamp is installed between the connecting shell and the water source triggering component to contact the liquid in the water storage container. When the water source triggering component is triggered by the liquid, the sterilizing lamp turns on to sterilize the liquid in the water storage container. This utility model, by setting a sterilization device with a sterilizing lamp at the end of the water pump pipe and incorporating a water source triggering component on the sterilization device to detect the liquid, allows the water source triggering component to detect the liquid by being triggered by it. Upon detection of liquid, the sterilizing lamp turns on to sterilize the liquid in the water storage container. Because the sterilizing lamp is in direct contact with the liquid and is not hidden within the connecting shell or the water source triggering component, it does not need to sterilize the liquid through the outer shell of the connecting shell or the water source triggering component. Therefore, the sterilization effect is good, preventing excessive bacteria levels in the liquid in the water storage container, making drinking safer. The water source triggering component can be set to trigger upon contact with the liquid in the water storage container, or it can be set to trigger when liquid is drawn out. Both triggering methods are based on the presence of liquid in the water storage container. Therefore, when the liquid in the water storage container is exhausted, the water source triggering component cannot be triggered. At this time, the germicidal lamp is in the off state. That is, when the liquid in the water storage container is exhausted, the water source triggering component can ensure that the germicidal lamp does not work, avoiding the germicidal lamp from continuing to work in the empty water storage container, which greatly saves power resources.

[0028] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0033] Example 1:

[0034] A tea bar machine, such as Figures 1 to 2As shown, the device includes a cabinet, a water storage container, and a water pump pipe 100. The water storage container is placed inside the cabinet to hold liquids such as drinking water and tap water. The lower end of the water pump pipe 100 extends into the water storage container to draw liquid from the container into a kettle or cup placed on top of the cabinet. A sterilization device is located at the lower end of the water pump pipe 100. The sterilization device includes a water source triggering component, a sterilizing lamp 300, and a connecting shell 200. The connecting shell 200 is installed at the end of the water pump pipe 100, and the sterilizing lamp 300 is installed between the connecting shell 200 and the water source triggering component, allowing the sterilizing lamp 300 to directly contact the drinking water or other liquids in the water storage container. When drawing liquid from the water storage container, the liquid sequentially passes through the water source triggering component, the sterilizing lamp 300, and the connecting shell 200 before entering the water pump pipe 100.

[0035] The water source triggering component can detect liquids by being triggered by them. It can be set to low-pressure triggering, meaning that when the sterilization device is inside the liquid in the water storage container, the pressure of the liquid itself can trigger the component, allowing it to detect the presence of liquid in the container. When liquid is present, the component is triggered, and the sterilization lamp 300 turns on to sterilize the liquid. Alternatively, the component can be set to high-pressure triggering. When the sterilization device is inside the liquid in the container, the pressure of the liquid itself is insufficient to trigger the component. However, when the pump pipe 100 draws liquid from the container, the pressure of the drawn liquid increases. Upon passing through the component and entering the pump pipe 100, the component is triggered, and the sterilization lamp 300 turns on to sterilize the liquid in the container.

[0036] This invention provides a sterilization device with a germicidal lamp 300 at the end of the water pipe 100, and a water source triggering component that can detect liquids on the sterilization device. The water source triggering component can detect liquids by being triggered by them, and then turn on the germicidal lamp 300 when liquids are detected to sterilize the liquids in the water storage container. Because the germicidal lamp 300 is in direct contact with the liquid and is not hidden in the connecting shell 200 or the water source triggering component, it does not need to sterilize the liquids through the outer shell of the connecting shell 200 or the outer shell of the water source triggering component. Therefore, the sterilization effect is good, preventing the bacteria in the liquid in the water storage container from exceeding the standard, making drinking safer. The water source triggering component can be set to trigger upon contact with the liquid in the water storage container, or it can be set to trigger when liquid is drawn out. Both triggering methods are based on the presence of liquid in the water storage container. Therefore, when the liquid in the water storage container is exhausted, the water source triggering component cannot be triggered. At this time, the germicidal lamp 300 is in the off state. That is, when the liquid in the water storage container is exhausted, the water source triggering component can ensure that the germicidal lamp 300 does not work, avoiding the germicidal lamp 300 from continuing to work in the empty water storage container, which greatly saves power resources.

[0037] In this embodiment, the water source triggering component includes a water-passing shell 410 and a triggering mechanism 420. The water-passing shell 410 is provided with a water-passing channel 4111 and a detection channel 4121. The water-passing channel 4111 is connected to the water pumping pipe 100. The triggering mechanism 420 is electrically connected to the germicidal lamp 300. The triggering mechanism 420 is installed on the top of the detection channel 4121. By installing the trigger mechanism 420 on top of the detection channel 4121, the water passage 4111 and the detection channel 4121 each perform different functions. When the pumping pipe 100 draws liquid, the liquid enters the water passage 4111 and the detection channel 4121 of the water source triggering component. The portion entering the water passage 4111 can enter the pumping pipe 100, and the portion entering the detection channel 4121 can be used to trigger the trigger mechanism 420. The water passage 4111 and the detection channel 4121 provide a certain degree of separation to the inside of the water passage shell 410, allowing a large amount of liquid to enter the pumping pipe 100 through the water passage 4111. This avoids a large amount of liquid impacting the trigger mechanism 420 and applying excessive pressure to it, thereby preventing damage to the trigger mechanism 420 due to excessive pressure and extending its service life.

[0038] In this embodiment, the triggering mechanism 420 includes a power supply module 421 and a triggering module 422, such as... Figure 2 As shown, the power supply module 421 contains a battery component and is electrically connected to the germicidal lamp 300 to supply power to the germicidal lamp 300. A microswitch 4211 is located at the bottom of the power supply module 421 for turning the germicidal lamp 300 on and off. The trigger module 422 is located below the microswitch 4211 and includes an integrally formed diaphragm 4221 and a trigger rod 4222. The diaphragm 4221 covers the top of the water passage 4111, and the trigger rod 4222 is vertically positioned on the side of the diaphragm 4221 facing the microswitch 4211. When the hydraulic pressure in the detection channel 4121 reaches a set value, the diaphragm 4221 deforms under pressure, pushing the trigger rod 4222 upwards from its center. When the trigger rod 4222 contacts the microswitch 4211 to close it, the power supply circuit is connected, and the power supply module 421 supplies power to the germicidal lamp 300 to turn it on. By configuring the triggering mechanism 420 as a combination of a micro switch 4211, a diaphragm 4221, and a trigger rod 4222, the diaphragm 4221 can be deformed by hydraulic pressure, which in turn drives the trigger rod 4222 to trigger the micro switch 4211. The extremely small deformation of the diaphragm 4221 can be transmitted to the micro switch 4211 through the trigger rod 4222 to realize the circuit connection, making the triggering mechanism 420 have high detection accuracy and more sensitive detection.

[0039] In this embodiment, as Figure 2As shown, the water-passing shell 410 includes an inner shell 412 and an outer shell 411. The outer shell 411 forms a water-passing channel 4111. The inner shell 412 is disposed inside the outer shell 411 to form a detection channel 4121. The inner shell 412 is fixed at the center of the outer shell 411, so that the water-passing channel 4111 surrounds the detection channel 4121. Because the detection channel 4121 is located at the center of the water passage 4111, when the water pumping pipe 100 pumps water, a portion of the liquid that flows into the water passage shell 410 will inevitably flow into the detection channel 4121. When the water source triggering component is set to be triggered when the liquid is pumped, the liquid in the detection channel 4121 can ensure the triggering of the water source triggering component, thereby ensuring that the sterilizing lamp 300 can be turned on to sterilize the liquid. Furthermore, by arranging the water passage 4111 around the detection channel 4121, the liquid flowing into the detection channel 4121 can be diverted from all sides to the water passage 4111, preventing the triggering mechanism 420 in the detection channel 4121 from being subjected to excessive pressure and thus preventing water from entering or being damaged.

[0040] Because the inlet of the water inlet of the water inlet shell 410 is located at the bottom of the water inlet shell 410, when the lower end of the water pump 100 is inside the water storage container, the bottom of the water inlet shell 410 of the sterilization device is very likely to press against the inner bottom wall of the water storage container, which will cause a certain degree of obstruction to the inlet of the water inlet shell 410. In this embodiment, multiple recesses 4112 are provided at the bottom of the outer shell 411. The multiple recesses 4112 are set with downward openings and penetrate through the outer shell 411, so that the side of the water inlet channel 4111 can communicate with the inside of the water storage container through the recesses 4112. When the water pump 100 draws liquid, the liquid in the water storage container can not only enter the water inlet channel 4111 through the bottom of the water inlet channel 4111, but also enter the water inlet channel 4111 through the recesses 4112 on the side of the water inlet channel 4111, so that the water pump 100 can draw it quickly.

[0041] In this embodiment, the germicidal lamp 300 can be detachably connected to the connecting shell 200 and the water-passing shell 410 through various locking methods, so that the germicidal lamp 300 can be disassembled and replaced when it is damaged. Preferably, such as Figure 1As shown, the germicidal lamp 300 includes an annular lamp strip 310 and annular connecting portions 320 at the upper and lower ends of the lamp strip 310. The connecting portion 320 at the upper end of the lamp strip 310 extends into the connecting shell 200 and is threadedly connected to the connecting shell 200. The connecting portion 320 at the lower end of the lamp strip 310 extends into the water-passing shell 410 and is threadedly connected to the water-passing shell 410. The lamp strip 310 is located between the connecting shell 200 and the water-passing shell 410. By setting the germicidal lamp 300 into a ring-shaped lamp strip 310, which is fixed to the connecting shell 200 and the water-passing shell 410 respectively through two connecting parts 320, the germicidal lamp 300 is made into a ring shape, which can increase the irradiation range of the liquid in the water storage container and irradiate the liquid around the germicidal lamp 300, resulting in a good sterilization effect. At the same time, the hollow structure of the lamp strip 310 can reserve sufficient space for the flow of liquid and the installation of the triggering mechanism 420, reducing the overall size of the sterilization device, so that the sterilization device can be inserted into the water storage container from the opening of the water storage container.

[0042] In this embodiment, the connecting shell 200 is provided with a liquid outlet 210 and a sleeve 220. The sleeve 220 is integrally formed on the connecting shell 200 and surrounds the liquid outlet 210. When the pumping pipe 100 is connected to the connecting shell 200, the sleeve 220 is fitted onto the end of the pumping pipe 100. A sealing ring 110 is clamped between the sleeve 220 and the pumping pipe 100 to enhance the sealing of the connection, so that the sleeve 220 and the pumping pipe 100 are sealed together, preventing liquid from entering the pumping pipe 100 from the gap between the pumping pipe 100 and the sleeve 220 when the pumping pipe 100 is drawing liquid. The sleeve 220 can increase the contact area between the pumping pipe 100 and the sterilization device, so that the sterilization device can be firmly assembled at the bottom of the pumping pipe 100, preventing the sterilization device from freely detaching from the bottom of the pumping pipe 100.

[0043] Example 2:

[0044] like Figure 3As shown, the difference between this embodiment and the first embodiment is that in this embodiment, the power supply module 421 is provided with a Hall switch 4212 at the bottom, and the trigger module 422 includes a float 4223 and a magnet 4224 embedded in the float 4223. The float 4223 is slidably connected in the detection channel 4121 below the Hall switch 4212. By configuring the triggering mechanism 420 as a combination of a Hall switch 4212 and a float 4223 equipped with a magnet 4224, when there is liquid in the water storage container, the liquid will enter the water passage 4111 and detection channel 4121 of the sterilization device immersed in the liquid. Under the action of buoyancy, the float 4223 in the detection channel 4121 drives the magnet 4224 to move closer to the Hall switch 4212 to trigger the Hall switch 4212, and the sterilization lamp 300 turns on to sterilize the liquid in the water storage container. When the liquid in the water storage container is exhausted, there is no liquid in the detection channel 4121, and the float 4223 falls under the action of gravity, driving the magnet 4224 away from the Hall switch 4212, no longer triggering the Hall switch 4212, and the sterilization lamp 300 turns off. This makes the triggering mechanism simple, reliable, not easy to damage, and has a long service life.

[0045] To prevent the float 4223 from detaching freely from the bottom of the detection channel 4121, this embodiment provides a stop step 4122 on the inner wall of the detection channel 4121. The stop step 4122 is located below the float 4223. When there is no liquid in the detection channel 4121, the float 4223 falls to the bottom under gravity and stops falling when it comes into contact with the stop step 4122. The stop step 4122 is preferably annular, which facilitates the passage of liquid while limiting the circumference of the bottom of the float 4223, resulting in a good limiting effect.

[0046] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
