Description

Technical Field

[0001] The utility model relates to a pressure water storage barrel and a water purifier. Background Art

[0002] With the popularity of water purifiers, especially commercial water purifiers, in order to improve the user experience of water discharge, water purifiers are equipped with pressure water storage barrels. Since the pressure water storage barrel has pressure, as long as the user opens the valve, the purified water stored in the pressure water storage barrel will flow to the water outlet under the action of pressure, achieving instant water discharge. At the same time, due to the existence of pressure in the barrel, it can also achieve large flow of water discharge, improving user experience. However, the interior of the pressure water storage barrel is a closed space surrounded by an airbag and a shell. If water is stored for a long time, bacteria are easily bred inside the barrel, which causes the total number of bacteria in the water quality to exceed the standard. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defect that bacteria in the pressure water storage barrel in the prior art easily exceed the standard, and to provide a pressure water storage barrel and a water purifier.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A pressure water storage barrel, comprising:

[0006] A shell having a sealed water storage cavity and a water inlet and outlet communicated with the water storage cavity;

[0007] A germicidal lamp unit is mounted on the housing and extends into the water storage cavity;

[0008] An impeller is installed at the water inlet and outlet and is located inside the water storage cavity.

[0009] In this solution, the pressure water storage barrel is equipped with a germicidal lamp unit in the water storage chamber. By turning on the germicidal lamp unit, the water in the water storage chamber is sterilized to prevent the growth of bacteria, so that the outlet water quality meets the hygienic and safety requirements. In particular, when making water, the filtered purified water enters from the water inlet and outlet of the pressure water storage barrel. As the purified water is squeezed into the pressure water storage barrel, it will flush the impeller installed at the water inlet and outlet and drive the impeller to rotate. After the impeller rotates, it will stir the water in the water storage chamber, so that the newly entered purified water and the water in the water storage chamber are fully mixed. At the same time, the sterilization effect of the germicidal lamp unit is further improved, the sterilization is more thorough, and the outlet water quality meets the safety requirements.

[0010] Preferably, the top of the shell has a mounting hole, and the germicidal lamp unit is mounted in the mounting hole and extends in a vertical direction.

[0011] In this solution, the germicidal lamp unit is installed on the top of the shell and extends in the vertical direction. Compared with installing it on the side, the germicidal lamp unit installed on the top is better stressed, so that the gravity is in the axial direction. Even if the pressure water storage tank vibrates, it will not cause damage to the germicidal lamp unit. If the germicidal lamp unit is installed horizontally, if there is a slight vibration, the germicidal lamp unit will be damaged by shear force, reducing its service life.

[0012] Preferably, a sealing ring is further provided between the germicidal lamp unit and the housing.

[0013] In this solution, a sealing ring is provided to improve the sealing effect between the housing and the germicidal lamp unit, prevent water leakage, and improve safety.

[0014] Preferably, the germicidal lamp unit comprises a germicidal lamp and a transparent protective cover, and the germicidal lamp is installed inside the protective cover.

[0015] In this solution, the germicidal lamp uses light to sterilize. The protective cover is used to protect the internal germicidal lamp to prevent the pressure in the water storage chamber from crushing the lamp tube of the germicidal lamp, thereby improving reliability. After the germicidal lamp is turned on, the light passes through the transparent protective cover, irradiates the purified water, and kills bacteria.

[0016] Preferably, the germicidal lamp unit further includes an elastic component, and two ends of the elastic component are respectively in contact with the lower end of the germicidal lamp and the inner wall of the protective cover.

[0017] In this solution, the elastic component is used to support the germicidal lamp, so that the germicidal lamp is firmly installed and prevents deflection. Especially when the pressure water storage tank vibrates, the elastic component forms a buffer to reduce the damage of the vibration to the germicidal lamp and improve the force on the germicidal lamp.

[0018] Preferably, the germicidal lamp is a mercury lamp or an ultraviolet lamp. The opening time of the germicidal lamp can be set by the intelligent control panel, and can be turned on for a period of time, turned off for a period of time, and turned on repeatedly according to a cycle, saving energy while not reducing the sterilization effect.

[0019] Preferably, a connector is installed on the water inlet and outlet, and a protective sleeve is provided on the peripheral side of the connector.

[0022] Preferably, the pressure water storage barrel further comprises a diaphragm, wherein the diaphragm is mounted on the shell to separate the inner cavity of the shell into a closed airbag cavity and the water storage cavity, and the diaphragm is elastic.

[0023] In this solution, when water flows into the water storage chamber, the water squeezes the elastic diaphragm, causing the diaphragm to deform and store potential energy, so that the water in the water storage chamber has a certain pressure. When the water inlet and outlet are opened, the water in the water storage chamber is pressed out by the diaphragm.

[0024] Preferably, the shell is further provided with a valve port, the valve port is used to connect the airbag cavity with the outside, a valve core is installed on the valve port, and the valve core is installed on the shell through a fastener.

[0025] In this solution, gas can be filled into or discharged from the airbag cavity through the air port to adjust the pressure in the airbag cavity, thereby adjusting the pressure of the pressure water storage tank.

[0026] Preferably, the inner wall of the shell also has a drainage pipe extending toward the interior of the water storage chamber, the water inlet and outlet are connected to the water storage chamber through the inner cavity of the drainage pipe, the impeller is installed in the drainage pipe, and a diverter is also provided in the drainage pipe. The diverter is located above the impeller and is used to divert water flowing to the middle of the impeller to the blades of the impeller.

[0027] In this solution, a flow divider is provided above the impeller to divide the water flowing into the water inlet and outlet, so that the water flows evenly to the impeller blades, thereby improving the rotation effect of the impeller and preventing the impeller shaft from being affected by water, thereby reducing the rotation effect of the impeller. The pressurized water entering the water inlet and outlet is used as power to drive the impeller to rotate, without the need for external power, thus saving energy.

[0028] A water purifier comprises the pressure water storage tank as described above.

[0029] On the basis of conforming to the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the utility model.

As the purified water is squeezed into the pressure water storage barrel, it will flush the impeller installed at the water inlet and outlet and drive the impeller to rotate. After the impeller rotates, it will stir the water in the water storage chamber, so that the newly entered purified water and the water in the water storage chamber are fully mixed, and at the same time, the sterilization effect of the sterilizing lamp unit is further improved, the sterilization is more thorough, and the water quality of the outlet meets the safety requirements.

[0057] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0058] like Figure 1-Figure 4 As shown, this embodiment discloses a pressure water storage barrel, which includes a shell 1, a germicidal lamp unit 2 and an impeller 3. The shell 1 has a closed water storage chamber 11 and a water inlet and outlet 13 connected to the water storage chamber 11. The germicidal lamp unit 2 is installed on the shell 1 and extends into the interior of the water storage chamber 11. The impeller 3 is installed on the water inlet and outlet 13 and is located inside the water storage chamber 11.

[0059] like Figure 4 As shown, in this embodiment, the pressure water storage barrel is equipped with a germicidal lamp unit 2 in the water storage chamber 11. By turning on the germicidal lamp unit 2, the water in the water storage chamber 11 is sterilized to prevent the growth of bacteria, so that the water quality meets the hygienic and safety requirements. In particular, when making water, the filtered purified water enters from the water inlet and outlet 13 of the pressure water storage barrel. As the purified water is squeezed into the pressure water storage barrel, it will flush the impeller 3 installed at the water inlet and outlet 13 and drive the impeller 3 to rotate. After the impeller 3 rotates, it will stir the water in the water storage chamber 11, so that the newly entered purified water and the water in the water storage chamber 11 are fully mixed. At the same time, the sterilization effect of the germicidal lamp unit 2 is further improved, the sterilization is more thorough, and the water quality of the outlet meets the safety requirements.

[0060] like Figure 4 As shown, the pressure water storage barrel further includes a diaphragm 4, which is installed on the shell 1 to separate the inner cavity of the shell 1 into a closed airbag cavity 12 and a water storage cavity 11, and the diaphragm 4 is elastic. When water enters the water storage cavity 11, the water squeezes the elastic diaphragm 4, causing the diaphragm 4 to deform and store potential energy, so that the water in the water storage cavity 11 has a certain pressure. When the water inlet and outlet 13 are opened, the water in the water storage cavity 11 is pressed out by the diaphragm 4. Preferably, the diaphragm 4 is made of hard rubber.

[0061] like Figure 1 and Figure 2 As shown, the housing 1 includes an upper cover and a lower cover, which are welded by rotational melting, and the edges of the diaphragm 4 are compressed during the overload of welding, and finally a closed pressure water storage tank is formed. A circular base is also provided at the bottom of the housing 1.

[0062] like Figure 2 and Figure 4 As shown, the housing 1 is also provided with an air port 14, which is used to connect the airbag cavity 12 with the outside, and a valve core 16 is installed on the air port 14, and the valve core 16 is installed on the housing 1 through a fastener 5. Through the air port 14, gas can be filled into or discharged from the airbag cavity 12 to adjust the pressure in the airbag cavity 12, and then adjust the pressure of the pressure water storage tank.

[0063] like Figure 2 and Figure 4 As shown, in this embodiment, the fastener 5 is a valve nut, which is threadedly connected to the threaded portion on the housing 1 and is used to fix the valve core 16 on the housing 1. By screwing the valve nut, it is easy to disassemble and assemble the valve core 16 so as to open or close the valve port 14.

[0064] like Figure 1 and Figure 4 As shown, the top of the housing 1 has a mounting hole 15, and the germicidal lamp unit 2 is mounted in the mounting hole 15 and extends in the vertical direction. The germicidal lamp unit 2 is mounted on the top of the housing 1 and extends in the vertical direction to avoid the airbag at the bottom. At the same time, compared with mounting it on the side, the germicidal lamp unit 2 mounted on the top is better stressed, so that the gravity is in the axial direction. Even if the pressure water storage tank vibrates, it will not damage the germicidal lamp unit 2. If the germicidal lamp unit 2 is mounted horizontally, if there is a slight vibration, the germicidal lamp unit 2 will be damaged by the shear force, reducing its service life.

[0065] like Figure 4 As shown, a sealing ring 6 is further provided between the germicidal lamp unit 2 and the housing 1 to improve the sealing effect between the housing 1 and the germicidal lamp unit 2, prevent water leakage, and improve safety.

[0066] like Figure 4 As shown, the germicidal lamp unit 2 includes a germicidal lamp 21 and a transparent protective cover 22, and the germicidal lamp 21 is installed inside the protective cover 22. The germicidal lamp 21 uses light to sterilize. The protective cover 22 is used to protect the internal germicidal lamp 21 to prevent the pressure in the water storage chamber 11 from crushing the lamp tube of the germicidal lamp 21, thereby improving reliability. After the germicidal lamp 21 is turned on, light passes through the transparent protective cover 22, irradiates the purified water, and kills bacteria.

[0067] like Figure 4 As shown, the germicidal lamp unit 2 also includes an elastic component 23, and the two ends of the elastic component 23 are respectively abutted against the lower end of the germicidal lamp 21 and the inner wall of the protective cover 22. The elastic component 23 is used to support the germicidal lamp 21, so that the germicidal lamp 21 is firmly installed and prevents deflection. Especially when the pressure water storage tank vibrates, the elastic component 23 forms a buffer to reduce the damage of the vibration to the germicidal lamp 21 and improve the force of the germicidal lamp 21. Preferably, the germicidal lamp 21 is a mercury lamp or an ultraviolet lamp. In this embodiment, the elastic component 23 is a pagoda buffer spring, the upper end of the pagoda buffer spring is sleeved on the lower end of the germicidal lamp 21, and the lower end of the pagoda buffer spring abuts against the lower inner wall of the protective cover 22.

[0068] The on time of the germicidal lamp 21 can be set through the intelligent control panel. It can be turned on for a period of time, turned off for a period of time, and turned on repeatedly according to a cycle, saving energy without reducing the sterilization effect.

[0069] like Figure 1 and Figure 4 As shown, a connector 17 is installed on the water inlet and outlet 13, and a protective sleeve 18 is provided on the peripheral side of the connector 17. By providing the connector 17, it is convenient to quickly connect with the external pipeline. The protective sleeve 18 is provided to protect the connector 17 from being damaged. Preferably, a card slot 181 is provided on the side wall of the protective sleeve 18, and the card slot 181 is used to pass the pipeline, and the card slot 181 can also be used to clamp and fix the pipeline.

[0070] like Figure 4 As shown, the inner wall of the housing 1 also has a drainage pipe 19 extending toward the inside of the water storage chamber 11, the water inlet and outlet 13 is connected to the water storage chamber 11 through the inner cavity of the drainage pipe 19, and the impeller 3 is installed in the drainage pipe 19. The drainage pipe 19 is also provided with a diverter 191, which is located above the impeller 3 and is used to divert the water flowing to the middle of the impeller 3 to the blades of the impeller 3. By providing the drainage pipe 19, the purified water entering the water inlet and outlet 13 is concentrated to flow to the impeller 3, thereby improving the driving force. The diverter 191 is provided above the impeller 3 to divert the water flowing into the water inlet and outlet 13 so that the water flows evenly to the blades of the impeller 3, thereby improving the rotation effect of the impeller 3 and preventing the shaft of the impeller 3 from being affected by water, thereby reducing the rotation effect of the impeller 3. The pressurized water entering the water inlet and outlet 13 is used as power to drive the impeller 3 to rotate, without the need for external power, thereby saving energy. In this embodiment, the flow divider 191 is a circular flow divider plate, and the circular flow divider plate is arranged in the middle above the impeller 3. Of course, in other embodiments, the flow divider 191 can also be conical.

[0071] The water inlet direction 10 from the water inlet and outlet 13 of the pressure water storage tank is as follows: Figure 4 As indicated by the arrow in .

[0072] This embodiment also discloses a water purifier, which includes the pressure water storage tank as described above.

[0073] When the clean water filtered by the water purifier enters from the water inlet and outlet 13 of the pressure water storage barrel, the water is squeezed into the water storage barrel, and the diaphragm 4 is compressed. When the clean water reaches the water storage volume required by the water purifier, no more water is added to the pressure water storage barrel. At this time, the sterilization lamp 21 starts to sterilize. The system defaults to turning on the sterilization lamp 21 for 15 minutes after the whole machine is full of water, and then turning it off for 15 minutes, and so on. In order to save energy, at the same time, as long as there is water extraction action, that is, when water flows out of the water inlet and outlet 13, the sterilization lamp 21 will be started and sterilized immediately. In addition, an impeller 3 and a diverter 191 located above the impeller 3 are installed at the water inlet and outlet 13. When water enters the water inlet and outlet 13, the water will first flow through the diverter 191, and the outflowing water will be dispersed and flow to the impeller 3. The water flow will drive the impeller 3 to rotate. After the impeller 3 rotates, it will stir the water in the pressure water storage barrel, so that the newly entered water and the stored water are fully mixed, further improving the sterilization effect of the sterilization lamp 21.
