Description

Technical Field

[0001] The utility model belongs to the technical field of sprayers, and in particular relates to a counting structure of a sprayer. Background Art

[0002] The atomization inhalation method uses high-speed oxygen airflow to make the drug solution into mist, which is then inhaled through the respiratory tract to achieve the purpose of treatment, treat respiratory tract infections, eliminate inflammation and edema, relieve spasms, thin sputum, and help expectoration. It is mainly composed of a nebulizer and a breathing mask. The nebulizer is used to make drug mist, and the drug solution is concentrated in the mouth and nose through the breathing mask for inhalation.

[0003] The above-mentioned sprayer can only be used in hospitals or homes and cannot be carried around. Therefore, a portable sprayer has been designed, in which a medicine bottle is installed. When used, the medicine in the medicine bottle is automatically sprayed out in the form of a spray, which is more convenient to use. When using this portable sprayer, since the user cannot intuitively see the remaining dose in the medicine bottle, a counting structure needs to be designed to count each use, so that the user can judge the remaining dose in the medicine bottle according to the number of uses. Utility Model Content

[0004] The utility model aims at solving the above problems in the prior art and proposes a counting structure for a sprayer.

[0005] The utility model can be realized through the following technical solutions:

[0006] A counting structure for a sprayer, comprising:

[0007] The capillary seat realizes the extraction and injection of the liquid medicine by the sprayer through its axial movement;

[0008] A spiral counting ring is sleeved on the capillary seat and the two are linked and cooperated, and the spiral counting ring is driven to rotate in situ through the axial movement of the capillary seat;

[0009] The counter has a counting rack on its inner wall, and the counting rack is connected with the external thread on the outer wall of the spiral counting ring. As the spiral counter rotates, the counting rack is driven to move for counting.

[0010] As a further improvement of the present invention, an upper gear ring and a lower gear ring are arranged up and down on the outer circumference of the capillary holder, and a receiving space is formed between the upper gear ring and the lower gear ring.

[0011] As a further improvement of the present utility model, a number of convex points are provided on the inner circumference of the spiral counting ring, and the convex points are located within the accommodating space. As the capillary seat moves up and down, the convex points move along the tooth surfaces of the upper gear ring and the lower gear ring, and drive the spiral counting ring to rotate in place.

[0012] As a further improvement of the present utility model, the upper gear ring and the lower gear ring are arranged in a staggered manner and have different inclination angles, so that during the axial movement of the capillary seat, the convex points always move unidirectionally. At this time, the spiral counting ring rotates unidirectionally and drives the counter to move unidirectionally.

[0013] As a further improvement of the present utility model, the capillary seat has a highest point position and a lowest point position along its axis direction.

[0014] As a further improvement of the present utility model, in the initial state, the capillary seat is located at the highest point position. When the sprayer completes a spraying action, the capillary seat moves from the highest point position to the lowest point position and then resets to the highest point position again. At this time, the spiral counting ring rotates one week and the counter completes a counting.

[0015] As a further improvement of the present utility model, it further includes a housing. The capillary seat is arranged in the housing so as to be movable up and down along the axis direction, and an opening is provided on the side of the housing.

[0016] As a further improvement of the present utility model, double-sided sliding buttons are provided on both sides of the capillary seat. The double-sided sliding buttons respectively extend outwards from the openings on both sides of the housing, and the axial downward pressure of the capillary seat is realized by pressing the double-sided sliding buttons.

[0017] As a further improvement of the present utility model, a pressure supply spring is further provided in the housing. When the double-sided sliding buttons are pressed to move the capillary seat to the lowest point position, the pressure supply spring is compressed. When the external force restricting the upward movement of the capillary seat is removed, the capillary seat resets to the highest point position under the action of the pressure supply spring.

[0018] As a further improvement of the present utility model, a support seat is further provided in the housing. The support seat is located at the bottom of the capillary seat and there is a distance between the two. The two ends of the pressure supply spring are respectively abutted against the capillary seat and the support seat.

[0019] Compared with the prior art, the present utility model has the following beneficial effects:

[0020] 1. By setting the capillary base, spiral counting ring, and counter as a linkage structure, during the spraying operation, as the capillary base moves axially, it will drive the counter to move up and down through the spiral counting ring, thereby recording the usage times or dosage of the device, facilitating users to monitor the remaining dosage and avoiding overuse or underuse.

[0021] 2. The upper gear ring and the lower gear ring are misaligned and have different inclination angles. When the capillary base moves axially, the convex point always moves unidirectionally along the tooth surface. At this time, the spiral counting ring rotates unidirectionally. Since the counting tooth surface of the counter meshes with the external thread of the spiral counting ring, with the unidirectional rotation of the spiral counting ring, the counter can be driven to move unidirectionally, thus achieving the purpose of quantitative counting of the counter.

[0022] 3. Through the setting of the bilateral slide buttons, when using, the user only needs to place the thumb on the bottom of the housing and press the bilateral slide buttons with the index finger and middle finger simultaneously to achieve the pressing action of the capillary base. The entire operation process can be completed with one hand, making it more convenient to use. Description of the Drawings

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figures 1-4 As shown, the utility model provides a counting structure of a sprayer, comprising:

[0035] The capillary seat 100 realizes the extraction and injection of the liquid medicine by the sprayer through its axial movement;

[0036] The spiral counting ring 110 is sleeved on the capillary holder 100 and the two are linked and cooperated. The axial movement of the capillary holder 100 drives the spiral counting ring 110 to rotate in the original position.

[0037] The counter 120 has a counting rack 121 on its inner wall, and the counting rack 121 is connected to the external thread 111 on the outer wall of the spiral counting ring 110. As the spiral counter 120 rotates, the counting rack 121 is driven to move for counting.

[0038] It should be noted that when the sprayer performs a spraying action, the capillary holder 100 has two movement processes. The first process is that by pressing down the capillary holder 100, the one-way valve of the capillary opens and the medicine in the medicine bottle 200 is extracted by vacuum. The second process is when the capillary holder 100 is reset upward, the one-way valve of the capillary closes and the medicine is pushed upward.

[0039] The focus of this embodiment is that the capillary holder 100, the spiral counting ring 110 and the counter 120 are arranged as a linkage structure. When the spraying action is performed, as the capillary holder 100 moves axially, the counter 120 is driven to move up and down through the spiral counting ring 110, so as to record the number of times the device is used or the amount of medicine, so as to help the user monitor the remaining dosage and avoid excessive or insufficient use.

[0040] Preferably, an upper gear ring 101 and a lower gear ring 102 are disposed up and down on the outer circumference of the capillary holder 100 , and a receiving space is formed between the upper gear ring 101 and the lower gear ring 102 .

[0041] Correspondingly, a plurality of protrusions 112 are provided on the inner circumference of the spiral counting ring 110, and the protrusions 112 are located in the accommodating space. As the capillary holder 100 moves up and down, the protrusions 112 move along the tooth surfaces of the upper gear ring 101 and the lower gear ring 102. At this time, since the axial position of the spiral counting ring 110 is limited by the sprayer, the purpose of driving the spiral counting ring 110 to rotate in situ by the up and down movement of the capillary holder 100 can be achieved.

[0042] Specifically, the upper gear ring 101 and the lower gear ring 102 are misaligned and have different inclination angles. During the axial movement of the capillary seat 100, the convex points 112 always move unidirectionally along the tooth surface. At this time, the spiral counting ring 110 rotates unidirectionally. Since the counting tooth surface of the counter 120 meshes with the external thread 111 of the spiral counting ring 110, with the unidirectional rotation of the spiral counting ring 110, the counter 120 can be driven to move unidirectionally, thus achieving the purpose of quantitative counting of the counter 120.

[0043] Preferably, the capillary seat 100 has a highest point position and a lowest point position along its axis. Specifically, in the initial state, the capillary seat 100 is located at the highest point position. When the sprayer completes one spray action, the capillary seat 100 moves from the highest point position to the lowest point position and then resets to the highest point position again. At this time, the spiral counting ring 110 rotates one week and the counter 120 completes one count.

[0044] That is, for each spray action, the counter 120 completes one count. Thus, the user can know how many remaining usage times are left according to the counting times of the counter 120, achieving the purpose of monitoring the remaining dose.

[0045] Preferably, it further includes a housing (not shown in the figure). The capillary seat 100 is arranged in the housing so as to be movable up and down along the axis direction, and an opening is provided on the side of the housing.

[0046] Preferably, both sides of the capillary seat 100 are provided with double-sided slide buttons 103. The double-sided slide buttons 103 respectively extend outwards from the openings on both sides of the housing. By pressing the double-sided slide buttons 103, the axial downward pressure of the capillary seat 100 can be realized. With such a setting of the double-sided slide buttons 103, when the user uses it, they only need to place the thumb on the bottom of the housing and press the double-sided slide buttons 103 with the index finger and middle finger at the same time to realize the downward pressing action of the capillary seat 100. The whole operation process can be completed with only one hand, making it more convenient to use.

[0047] Preferably, there is also a pressure spring 130 in the housing. When pressing the double-sided slide buttons 103 to move the capillary seat 100 to the lowest point position, the pressure spring 130 is compressed. When the external force restricting the upward movement of the capillary seat 100 is removed, the capillary seat 100 resets to the highest point position under the action of the pressure spring 130. During the process of the capillary seat 100 resetting to the highest point, its capillary can smoothly push out the liquid medicine.

[0048] Preferably, a support seat 140 is also provided in the housing. The support seat 140 is located at the bottom of the capillary seat 100 and there is a distance between them. The two ends of the pressure spring 130 respectively abut against the capillary seat 100 and the support seat 140 to ensure the stability of the pressure spring 130 after installation.

The above are the specific embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
