## Background
FIELD OF THE INVENTION
The present invention is in the field of vapor inhalers.
DISCUSSION OF RELATED ART
Smokers are addicted to nicotine found inside cigarettes. However, nicotine is only one reason why cigarettes are harmful. Cigarettes also contain tar and consist of other carcinogenic ingredients that contribute to the overall decline on human health with prolonged usage. Smokers also endanger surrounding people when they smoke. After inhaling then exhaling on a cigarette, the air exhaled comprises of more than carbon monoxide. Remnants of the cigarette's carcinogenic components linger in the air for a passerby to involuntarily inhale. Fortunately, regulations exist to reduce such occurrences and smoking in public area has mostly been prohibited in developed countries.
With social pressure to quit smoking and the devastating side effects of smoking, users have sought several methods to reduce or cease their habit. Some common methods include the usage of nicotine patches or nicotine gum to curb nicotine cravings. Therapy and support groups also exist to provide encouragement throughout the process. More recently is the invention of vapor inhalers configured as electronic cigarettes that contain nicotine, which proposes to help ease users off real cigarettes by simulating the appearance, feel, and pleasure derived from smoking. A variety of different vapor inhalers have been used for allowing a user to inhale vapor such as Lik Hon, U.S. Pat. No. 8,511,318, issued on Aug. 20, 2013, entitled Electronic Cigarette disclosed herein by reference. Hon teaches about a vapor inhaler that includes a shell, a cell, nicotine solution, control circuit, and an electro-thermal vaporization nozzle installed in the air suction of the end shell; stating the advantages of which include smoking without tar, reducing cancer risk, simulation of smoking experience, and no fire danger since the cigarette is not lit. Another example of vapor inhalers is Tucker et al., U.S. 2013/0192620, issued Aug. 1, 2013, entitled Electronic Cigarette disclosed herein by reference. Tucker discloses an electronic smoking article that includes a heater operable to heat liquid material, a wick to deliver the liquid material to the heater, an inlet to deliver air, and a fibrous element downstream of the heater.
To greater enhance the simulation of smoking other types of vapor inhalers enable users to add flavoring agents such as tobacco flavor or menthol. Kyle Newton, U.S. 2013/0228191, issued on Sep. 5, 2013, entitled Electronic Cigarette with Liquid Reservoir disclosed herein by reference. Newton introduces an elongated housing that serves as a liquid reservoir chamber, which proposes to extend the duration in between time when users would need to change a flavoring cartridge.
Vapor inhalers also seek to emulate other aspects of a real cigarette. Mark Scatterday, U.S. Pat. No. 8,539,959, issued on Sep. 24, 2013, entitled Electronic Cigarette Configured to Simulate the Natural Burn of a Cigarette disclosed herein by reference. Scatterday proposes an electronic cigarette which may have a translucent conduit and light chamber, allowing light from the light source to be diffused in such a way that the light emitted during inhalation simulates the natural burn of a traditional tobacco cigarette.
The present inventions seeks to enable users the ability to regulate the amount of vapors inhaled in one breath, which has not yet been demonstrated by prior art. This ability also allows a multitude of users, who are most likely on different stages of quitting, to adjust to an amount of smoking that is appropriate to their individual needs.

The mixture of ambient air and vapor then passes through the main body secondary outlet 85, and finally through the mouthpiece channel 93 to the user.
The sum of the cross sectional area of the heater air intake opening 35 should be smaller than the cross sectional area of the main body secondary outlet 85. The cross section area of the main body regulator valve cavity air outlet 83 should be smaller than the main body secondary outlet 85. The main body secondary outlet 85 passes through a top wall of the main body which is defined as the main body mouthpiece mesa 89. Similarly, the main body regulator valve cavity air outlet 83 passes through the top wall of the main body and exits as the main body vapor outlet 86.
The user can press the regulator valve intermittently, not at all, or continuously so that the user can control the precise concentration of the vapor being inhaled. Different users may prefer a rich or lean mixture of vapor and air. A user that is trying to quit smoking can start with a rich mixture and work toward a lean mixture to gradually taper off in nicotine usage. The mouthpiece is preferably of transparent plastic so that the user can see the vapor being inhaled. When a user wants to stop inhaling, the user can press the regulator valve and the column of vapor will break siphon and the vapor will purge outward through the heater air intake opening by virtue of density difference between supplemental ambient air and vapor.
The heater is preferably modularly removable. By making the heater a separate unit that is threaded attached and sealed by O-rings, it allows easy cleaning and easy replacement.
