Abstract

Claims (52)

1. An assembly for a pool or spa system comprising:

a housing;

a disposable chemical container for fluidly sealing a chemical in an inner volume of the disposable chemical container, wherein the disposable chemical container is housed in the housing;

a pump coupled to the disposable chemical container for injecting the chemical into a fluid flow of the pool or spa system;

a sensor configured to measure an amount of the chemical in the disposable chemical container;

a processing device communicatively coupled to the sensor and configured to determine if the amount is below a threshold; and

a communication circuit communicatively coupled to the processing device and configured to request a replacement assembly when the amount is below the threshold.

2. The assembly of claim 1 , wherein the chemical is sealed in the inner volume of the disposable chemical container prior to the pump coupling to the pool system or the spa system.

3. The assembly of claim 1 , further comprising:

a second processing device communicatively coupled to the pump for activating the pump to inject a second amount of the chemical based on a characteristic of the fluid flow; and

a second sensor communicatively coupled to the second processing device for measuring the characteristic of the fluid flow.

4. The assembly of claim 3 , wherein the second sensor is for measuring an acidity of fluid in the fluid flow, wherein the chemical is an acid for adjusting the acidity of the fluid, and wherein the pump is calibrated for dispensing the acid in a standardized dose to allow treatment of the fluid.

5. The assembly of claim 1 , further comprising:

a second processing device communicatively coupled to the pump for activating the pump to inject a second amount of the chemical based on an instruction from a user; and

a second communication circuit communicatively coupleable to the second processing device for receiving the instruction from the user.

6. A system comprising:

a tubing coupled to a pool or a spa for allowing a fluid in the pool or the spa to flow therethrough;

a chemical injector coupled to the tubing comprising:

a pump for injecting a chemical into the tubing; and

a disposable chemical container coupleable to the pump, the disposable chemical container including a seal for retaining the chemical in an inner volume of the disposable chemical container, wherein the seal opens in response to the disposable chemical container being coupled to the pump to allow the chemical to be injected by the pump into the tubing;

a sensor configured to measure an amount of the chemical in the disposable chemical container;

a processing device communicatively coupled to the sensor and configured to determine if the amount is below a threshold; and

a communication circuit communicatively coupled to the processing device and configured to request a replacement disposable chemical container when the amount is below the threshold.

7. The system of claim 6 , wherein the chemical is sealed in the inner volume of the disposable chemical container prior to the disposable chemical container being coupled to the pump.

8. The system of claim 7 , wherein the seal of the disposable chemical container is a valve for coupling to the pump and opening to create a passageway between the inner volume of the disposable chemical container and the pump.

9. The system of claim 7 , wherein the seal of the disposable chemical container is opened by a member of the pump piercing the seal to create a passageway between the inner volume of the disposable chemical container and the pump.

10. The system of claim 6 , further comprising:

a second processing device communicatively coupled to the pump for activating the pump to inject a second amount of the chemical based on a characteristic of a fluid flow; and

a second sensor communicatively coupled to the second processing device for measuring the characteristic of the fluid flow.

11. The system of claim 10 , wherein the second sensor is for measuring an acidity of fluid in the fluid flow, wherein the chemical is an acid for adjusting the acidity of the fluid, and wherein the pump is calibrated for dispensing the acid in a standardized dose to allow treatment of the fluid.

12. The system of claim 6 , further comprising:

a second processing device communicatively coupled to the pump for activating the pump to inject a second amount of the chemical based on an instruction from a user; and

a second communication circuit communicatively coupleable to the second processing device for receiving the instruction from the user.

13. The system of claim 6 , wherein the pump is a first pump, the system further comprising:

a second pump coupled to the tubing for pumping the fluid through the tubing;

a filter coupled to the tubing for filtering the fluid; and

a check valve coupled to the tubing for limiting a direction of a flow path in the tubing.

14. A method comprising:

providing a chemical for treating a fluid in a pool system or a spa system;

providing a disposable chemical container having an inner volume for housing the chemical;

providing a seal for sealing the chemical in the inner volume of the disposable chemical container, wherein the seal opens in response to the disposable chemical container being positioned in a chemical injector coupled to the pool system or the spa system;

providing a sensor configured to monitor an amount of the chemical in the inner volume of the disposable chemical container;

providing a processing device configured to communicatively couple to the sensor to determine if the amount is below a threshold; and

providing a communication circuit configured to communicatively couple to the processing device to request a replacement disposable chemical container when the amount drops below the threshold.

15. The method of claim 14 , wherein the seal is an integrated pump for injecting the chemical into the pool system or the spa system.

16. The method of claim 14 , further comprising:

providing a tubing for coupling to the pool system or the spa system to allow fluid from the pool system or the spa system to flow therethrough; and

providing an injection pump for coupling to the tubing to form the chemical injector that is coupleable to the disposable chemical container.

17. The method of claim 16 , the method further comprising:

providing a second pump for coupling to the tubing to pump the fluid through the tubing;

providing a filter for coupling to the tubing to filter the fluid; and

providing a check valve for coupling to the tubing to limit a direction of a flow path in the tubing.
