Portable oxygen tank aerosol valve

Abstract

The invention discloses a portable oxygen tank aerosol valve, relates to the field of portable oxygen tank aerosol valves, and overcomes the defects that a portable oxygen tank oxygen inhalation device for inhaling oxygen in a nasal plug mode in the current market is relatively complicated in structure and composition, difficult in accurate flow control, relatively many in air leakage points and relatively high in production cost. According to the oxygen tank oxygen inhalation device (figure 4) of the aerosol valve (figure 3), a valve element on a valve cup is removed and replaced with a gum cushion, and the oxygen tank oxygen inhalation device is suitable for being used for an under-cover oxygen filling machine. Due to the fact that the filling pressure of oxygen can automatically and firmly inlay the gum rubber mat at the position of the air outlet of the valve cup, the air outlet is sealed tightly, oxygen does not leak, oxygen can be smoothly inhaled by inserting a special oxygen inhalation tube with a needle into the sealing rubber mat during oxygen inhalation, adjustment of any adjusting device is not needed, and the product is particularly suitable for being used by middle-aged and elderly people.

Description

Technical Field

[0001] Portable oxygen tank aerosol valve. Background Art

[0002] The current situation of portable oxygen tank oxygen inhalation devices on the market that use nasal congestion to inhale oxygen: Structure and composition: It consists of a tank body, an aerosol valve ( Figure 2 ), regulating valve base, regulating valve knob, oxygen inhalation tube, nasal plug and flow meter, etc., such as patent number: ZL2005 20105505.0 portable oxygen tank product oxygen inhalation device ( Figure 1 ). This structure and composition are relatively complex, the flow rate is difficult to control accurately, there are many leakage points, and there are disadvantages of high production costs. Summary of the invention

[0003] The aerosol valve of the present invention ( Figure 3 ) oxygen tank oxygen breathing device ( Figure 4 ) is simple, convenient, leak-free, and reduces production costs. The aerosol valve for the portable oxygen tank of the present invention ( Figure 3 ) not only replaces the original aerosol valve ( Figure 2 ), and omitted the regulating valve base, regulating valve knob and flow meter and other connecting components, the sealing effect is also significantly better than the original aerosol valve ( Figure 2 ), the product is especially suitable for middle-aged and elderly people. BRIEF DESCRIPTION OF THE DRAWINGS

[0004] Figure 1 :ZL2005 2 0105505.0 Utility Model; Figure 2 : Currently aerosol valve; Figure 3 : Aerosol valve of the present invention; Figure 4 : The oxygen tank oxygen inhalation device of the aerosol valve of the present invention. DETAILED DESCRIPTION

[0005] The present invention removes the valve core from the valve cup and replaces it with a back-adhesive pad, which is suitable for use in an oxygen filling machine under the cover. The back-adhesive pad will automatically and firmly embed at the air outlet of the valve cup due to the filling pressure of oxygen, and the air outlet is tightly sealed to prevent oxygen leakage. When inhaling oxygen, a special oxygen inhalation tube with a needle is inserted into the sealing pad to smoothly inhale oxygen without any adjustment device.

Claims

1. Remove the valve core from the valve cup and replace it with a rubber pad with adhesive backing, which is suitable for use in an under-cover oxygen filling machine, because the filling pressure of oxygen will automatically and firmly embed the rubber pad with adhesive backing in the air outlet of the valve cup.

2. The aerosol valve of the present invention used in a portable oxygen tank (portable oxygen inhaler) according to claim 1.

3. The aerosol valve of the present invention filled with other aerosols according to claim 1.
