Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, specifically to a faucet water purifier with a filter replacement reminder function. Background Technology

[0002] A faucet water purifier is a water purification device installed on a faucet. It is becoming increasingly popular due to its ease of installation and ability to directly filter water flowing from the faucet. Existing faucet water purifiers have an inlet at the top and an outlet at the bottom. During installation, the faucet is connected to the inlet, allowing water to enter the faucet water purifier through the inlet, be filtered by the internal water filter element, and then flow out from the outlet.

[0003] The water filter cartridge in a faucet water purifier is a consumable that needs to be replaced regularly. However, different users have different usage patterns, and it is difficult for users to accurately determine whether the filter needs to be replaced based on usage time. If the filter cartridge is forgotten or replaced too late, it can easily lead to secondary pollution of drinking water. If it is replaced too early, it will result in waste of consumables. Therefore, it is necessary to install a filter cartridge replacement reminder device in the use of faucet water purifiers to remind users to replace the filter cartridge in time.

[0004] Currently, filter replacement reminder devices on the market generally suffer from problems such as large size, complex structure, high precision requirements, poor repair or replacement capability, and high cost. Therefore, the water purification industry urgently needs a filter replacement reminder device that is simple in structure, easy to repair and replace, small in size, and low in cost to solve the industry's pain points. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a faucet water purifier with filter replacement reminder function, simple structure, low cost and convenient maintenance and replacement.

[0006] The technical solution of this utility model is to provide a faucet water purifier with a filter replacement reminder function having the following structure: The device includes a water purifier body with a water passage. The water purifier body also includes a flow statistics module and a switch control module, with the switch control module located inside the flow statistics module. A trigger switch is located at one end of the flow statistics module facing the switch control module. A touch lever assembly corresponding to the trigger switch is located at one end of the switch control module near the flow statistics module. An elastic drive member connected to the touch lever assembly is located at the other end of the switch control module. The end of the elastic drive member away from the touch lever assembly extends into the water passage. When the water purifier is turned on, water flows through the water passage, generating water pressure. The elastic drive member is squeezed by the water flow, pushing the touch lever assembly towards the trigger switch. When the touch lever assembly contacts the trigger switch, it controls the activation of the flow statistics module, calculating the flow rate based on the water output time. When the water purifier is turned off, the water pressure in the water passage is zero. The elastic drive member automatically resets upon losing water pressure, disengaging the touch lever assembly from the trigger switch, and the flow statistics module stops.

[0007] Preferably, the water purifier body is provided with a mounting groove, and the inner bottom wall of the mounting groove is provided with a through hole communicating with the water passage; the switch control module is connected to the inner bottom wall of the mounting groove, and the elastic drive component is sealed and fitted in the through hole; the flow statistics module is detachably connected to the mounting groove and is located outside the switch control module.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model discloses a faucet water purifier with a filter replacement reminder function, including a water purifier body 1 and a flow statistics module 2 and a switch control module 3 connected to the water purifier body 1.

[0027] like Figure 2 and Figure 3 As shown, the water purifier body 1 has a mounting groove 11, and a through hole 12 is provided on the inner bottom wall of the mounting groove 11. The water purifier body 1 has a water passage, and the through hole 12 communicates with the water passage. The switch control module 3 is connected to the inner bottom wall of the mounting groove 11, and the flow statistics module 2 is detachably connected to the mounting groove 11 and is located outside the switch control module 3.

[0028] like Figure 2 , Figure 4 and Figure 6 As shown, the switch control module 3 includes a touch lever assembly 31, an elastic drive member 32, and a connecting seat 33. The connecting seat 33 is provided with a vertically extending guide post 331, and the guide post 331 is provided with guide holes 332 penetrating its two end faces. The elastic drive member 32 is connected to the guide post 331, and the touch lever assembly 31 is slidably connected in the guide hole 332.

[0029] The connecting seat 33 has a radially extending connecting part 333 on one side wall, and a connecting hole 334 on the connecting part 333; a connecting stud 13 is provided on the inner bottom wall of the mounting groove 11 at a position corresponding to the connecting hole 334. By passing a screw through the connecting hole 334 and threading it with the connecting stud 13, the connecting seat 33 can be fixed on the connecting stud 13.

[0030] The elastic drive component 32 includes an elastic body 321 that is hollow inside and has an opening at the lower end. The elastic body 321 is sleeved on the guide post 331 and is interference-fitted with the outer peripheral wall of the guide post 331 to prevent water leakage.

[0031] The end of the elastic body 321 away from the touch stick assembly 31 is disposed in the through hole 12, and multiple radial protrusions 322 are provided on the outer peripheral wall of the elastic body 321. The radial protrusions 322 are interference-fitted in the through hole 12 to play a sealing role and prevent water in the water passage from overflowing from the gap between the elastic body 321 and the through hole 12.

[0032] The touch stick assembly 31 includes a push rod 311 and a guide ring 312; the push rod 311 is connected to the inner top wall of the elastic body 321, and the guide ring 312 is sleeved on the push rod 311 and is clearance-fitted with the guide hole 332.

[0033] For example Figure 4 and Figure 5 As shown, the flow statistics module 2 includes a housing 22, a trigger switch 21 disposed on the inner end face of the housing 22, a display screen 23 disposed on the outer end face of the housing 22, and a circuit board 24 disposed inside the housing 22; the display screen 23 and the trigger switch 21 are electrically connected to the circuit board 24.

[0034] The aforementioned trigger switch 21 can be a contact mechanical switch, magnetic switch, capacitive induction switch, etc., which triggers the operation of the flow statistics module 2 by approaching or contacting the push rod 311. The flow statistics module 2 also includes a control button 26, a calculation module 27, and a power supply. The control button 26 can operate the display screen 23, and the calculation module 27 can calculate the flow rate and display it on the display screen 23.

[0035] When the faucet water purifier of this utility model is turned on, water flows through the water passage, generating water pressure. The elastic body 321 on the elastic drive component 32 is squeezed, which drives the touch control rod assembly 31 to push towards the trigger switch 21. With the cooperation of the guide ring 312 and the guide hole 332, the free end of the push rod 311 passes through the guide hole 332 and contacts the trigger switch 21, controlling the start of the flow statistics module 2, calculating the flow rate according to the water output time, and displaying it on the display screen 23.

[0036] When the faucet water purifier of this utility model is turned off, the water pressure in the water passage drops, and the elastic body 321 on the elastic drive component 32 loses the push of the water pressure. It will automatically reset under its own elastic force, and drive the push rod 311 on the touch control rod group 31 to disengage from the trigger switch 21, and the flow statistics module 2 stops calculating.

[0037] like Figure 3 and Figure 4 As shown, the inner bottom wall of the mounting groove 11 is provided with a mounting hole 111, and a first magnetic block 112 is connected inside the mounting hole 111. A second magnetic block 25 is provided on the inner end face of the outer casing 22 at a position corresponding to the first magnetic block 112. The first magnetic block 112 and the second magnetic block 25 are magnetically attracted to each other to prevent the flow statistics module 2 from automatically detaching from the mounting groove 11. The first magnetic block 112 can be a permanent magnet (such as a neodymium iron boron magnet), and the second magnetic block 25 can be an iron sheet to reduce material costs.

[0038] For example Figure 4 As shown, a notch 221 is also provided on one side of the inner end face of the outer casing 22, which makes it easy for the user to remove the flow statistics module 2 from the mounting slot 11.

[0039] This utility model of a faucet water purifier with a filter replacement reminder function has an independent flow statistics module 2 and a switch control module 3 on the water purifier body 1. The flow statistics module 2 is activated by the switch control module 3 contacting the trigger switch 21 (that is, when the water purifier is turned on, water flows through the water passage of the water purifier body 1 and generates water pressure. The elastic drive member 32 is squeezed by the water flow, which drives the touch rod group 31 to push towards the trigger switch 21. When the touch rod group 31 contacts the trigger switch 21, it controls the activation of the flow statistics module 2. At this time, the flow statistics module 2 can calculate the flow rate based on the water output time. When the water purifier is turned off, the water pressure in the water passage is zero. The elastic drive member 32 automatically resets when the water pressure is lost, and drives the touch rod group 31 to disengage from the trigger switch 21, and the flow statistics module 2 stops). This utility model is small in size, simple in structure, and low in cost. Moreover, the flow statistics module 2 is an independent unit and does not need to be forcibly fixed to the water purifier product. It can be removed separately during replacement and maintenance, making maintenance and replacement convenient.

[0040] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
